I am Lim Yueh Hwa from Secondary 2A and my index number is 20. I will protect my family, relatives, church friends, close school friends, my most favourite items, such as my laptop, psp, and hand phone, and last but not least, my country. I will protect my parents as they are ones who gave me support and raised me up together with my siblings. Since I have a close bond with my siblings, i will also protect them. Next, I will protect my relatives as we spent our childhood time playing together. My aunties and uncles also play a part in giving me advice. My church friends and I also played together since young and I have many wonderful childhood memories. They also celebrated my birthday with me and gave me birthday presents. I also have a close bond with them. When I am bored and when I have nothing to do, and when my relatives and church friends are not at my house, I will use my laptop or play my psp. I may also use my hand phone to send text messages or call my friends, be it school friends or church friends. Hence, I will also protect them. Finally, I would do my best to protect my country as that is where I live. Without my country, I would have to find somewhere else to live.

This week we had to finish up the draft of our IPW and hand it in. Yueh Hwa and Malcolm did the main body while me and Justin did parts of them, adding to the total. Fortunately on thursday, we were able to complete the draft and our IPW teacher allowed us to print it and hand it to him.

I think our group should keep track of time and hand in our work early and not last minute like on thursday.

Today we finally decided on our product, a video on how to prevent dengue with Justin as the main actor. The deadline, unfortunately,is this week and this week we are rather busy ourselves for the IPW project so we have managed to find time on thursday to get together and make the product. We have also have tasks distributed to us by our leader Yueh Hwa. I am doing the cover for the slide show, Justin and Yueh Hwa doing the main body in which i think we will edit further on on thursday. I hope we can complete the project in time for submission.

Reflection 10 - Justin

This week we spread out the work for the report and are hoping to get it done by the end of the week. I will be working on the abstract, background and introduction. Sounds like a lot of work? Well the one with the most work is doing the main body. I have to agree with Yueh Hwa about the group being disorganized and distracted. I must admit a few times i have been distraceted myself haha .. but at least i still get the work done. The deadline for our report and prodect is the end of this week, most probably there will be some difficulties in completion but i will try my best. Yueh Hwa, your the group leader, you should try to take charge a bit more.

Reflection 9 - Justin

We finaly completed the summary of our survey findings and have posted them on the blog. This week the teacher suggested that we come up with a product, so we brainstormed for ideas. We are also required to submit a group report of over a few thousand words.

Grace Blog Reflection 10 - Lim Yueh Hwa

This week we discussed about what to write for our group report. We will be working on it sometime this week and should be ready by next week. I feel that the group is quite disorganized as they are very distracted by other things such as pictures, games and so on. I also few that one of the group members is not contributing to our project at all. 

reflection 9-Gavin

Today we finally managed to get the blog working again and so i could finally post the final survey results after a week of delay. We also got some tips on how to make our product and we are planning on making the product really soon as we have almost decided on what product to make.

The product should be about a video about dengue.

Grace Blog Reflection 9 - Lim Yueh Hwa

Today, we finally presented most of our survey findings on our blog. Our teacher gave us a very useful suggestion for our product that we could consider. We will be posting the full findings and statistics for our survey by midnight today. We will also be working on our product as soon as possible.  

Grace Blog Reflection 8 - Lim Yueh Hwa

Last week, we were supposed to present our survey findings and statistics on the blog but I fell sick and was unable to come to school. What I heard from my teammates was that they started to brainstorm on what our product would be.  

Reflection 8 - Justin

This week we finished all the surveys and came together with the results. Unfortunately, yueh hwa, our group leader was sick and did not come to school. So we were unable to sum up our survey. Instead we brainstormed for ideas.

reflection 8 - Gavin

today we brought our filled survey forms to school for Yueh Hwa to check and see if they could be handed in. A couple of incomplete survey forms were rejected and I was told to ask someone else to do the survey. Yueh Hwa also wanted the names and occupations of the people who did the surveys so I had to bring back mine to wright down the names. Last week I was supposed to go to Yueh Hwa's house for the project on Monday but I did not go as i had CCA so I did not have much idea what to do for the surveys.

Malcolm Wu - Research on the Life Cycle of a Mosquitoe

IPW Research – Life Cycle of Mosquitoes

The mosquito goes through four separate and distinct stages of its life cycle and they are as follows: Egg, Larva, pupa, and adult. Each of these stages can be easily recognized by their special appearance. There are four common groups of mosquitoes living in the Bay Area. They are Aedes, Anopheles, Culex, and Culiseta. 

Egg : Eggs are laid one at a time and they float on the surface of the water. In the case of Culex and Culiseta species, the eggs are stuck together in rafts of a hundred or more eggs. Anopheles and Aedes species do not make egg rafts but lay their eggs separately. Culex, Culiseta, and Anopheles lay their eggs on water while Aedes lay their eggs on damp soil that will be flooded by water. Most eggs hatch into larvae within 48 hours. 

Larva : The larva (larvae - plural) live in the water and come to the surface to breathe. They shed their skin four times growing larger after each molting. Most larvae have siphon tubes for breathing and hang from the water surface. Anopheles larvae do not have a siphon and they lay parallel to the water surface. The larva feed on micro-organisms and organic matter in the water. On the fourth molt the larva changes into a pupa.

Pupa: The pupal stage is a resting, non-feeding stage. This is the time the mosquito turns into an adult. It takes about two days before the adult is fully developed. When development is complete, the pupal skin splits and the mosquito emerges as an adult.

Adult: The newly emerged adult rests on the surface of the water for a short time to allow itself to dry and all its parts to harden. Also, the wings have to spread out and dry properly before it can fly.

The egg, larvae and pupae stages depend on temperature and species characteristics as to how long it takes for development. For instance, Culex tarsalis might go through its life cycle in 14 days at 70 F and take only 10 days at 80 F. Also, some species have naturally adapted to go through their entire life cycle in as little as four days or as long as one month

Reflection 7 - Justin

This week we reviewed the survey questions. It turns out some question were not very good or could not carry out the right message. So Mr Seow recommended that we rephrase our questions. We also decided that we we should interview about 20 to 30 people. During the holidays we will try to get together and finish up our survey questions and start surveying people. Hope to complete the task by the end of the school holidays. Will be difficult due the team members individual activities...

reflection 7 - Gavin

This week we added on the number of people to be surveyed and edited the survey questions even more. We increased the number of people to be surveyed from 20 to 30. Our questions were also reviewed by our teacher and we were asked to go through them again and see if we could come u with better questions. The teacher also gave us some idea on how to present.

Grace Blog Reflection 7 - Lim Yueh Hwa

This week, we are supposed to come with our survey questions, show it to our teacher, formalize it (putting it into a table), conduct our survey by asking other people and going to various places to interview them and finally, after the blog, post our reflections about how we felt about the survey.  

Malcolm Wu Week 7

This week, we were suppose to make survey questions for our interview but we had already done it. It was just that our questions we made up are reasonable but we have to rephrase them as it didn't seem to be in proper english or wasn't written properly. Therefore we had to spend about half of the period asking someone that is good in english to help us think of ways to make our questions sound better so that the people that we are going to interview have a much better understanding of what we are trying to ask and hopefully can give us a much more fulfilling answer or one that we most probably want to hear. After that, we still have to post our survey questionnaires on our blog and once we have done that, we have to conduct our surveys and after which, we still have to write down our experience on surveying the people and describe how we felt and our reactions when interviewing them on our blog

This week to catch up on our IPW project me and Justin went to Yueh Hwa's house. We thought of survey questions and how we would present them. We decided on multiple choices and in Yes and No choices. below the Yes and No choices also had some other choices and a free answer choice. We are now waiting for Yueh Hwa to send us the soft copies and print some hard copies as well. I think we did fairly well this week for the IPW project.

Reflection 6 - Justin

This week, Gavin and I went to Yueh Hwa's house to complete the survey questions.
So whats left is survey some people. Both Yueh Hwa and I have completed the research, i am unsure of the progress of of Gavin and Malcolm though. Anyways the CA's are here so we will be taking a short break from IPW for a while. Hopefully we can complete everything after the exams...

Dengue Fever Research - Signs and Symtoms - Lim Yueh hwa

This is manifested by a sudden onset of severe headache, muscle and joint pains (myalgias and arthralgias—severe pain gives it the name break-bone fever or bonecrusher disease), fever, and rash.^[5] The dengue rash is characteristically bright red petechiae and usually appears first on the lower limbs and the chest; in some patients, it spreads to cover most of the body. There may also be gastritis with some combination of associatedabdominal pain, nausea, vomiting, or diarrhea.

Some cases develop much milder symptoms which can be misdiagnosed as influenza or other viral infection when no rash is present. Thus travelers from tropical areas may pass on dengue in their home countries inadvertently, having not been properly diagnosed at the height of their illness. Patients with dengue can pass on the infection only through mosquitoes or blood products and only while they are still febrile.

The classic dengue fever lasts about six to seven days, with a smaller peak of fever at the trailing end of the disease (the so-called biphasic pattern). Clinically, the platelet count will drop until the patient's temperature is normal.

Cases of DHF also show higher fever, variable haemorrhagic phenomena, thrombocytopenia, and haemoconcentration. A small proportion of cases lead to dengue shock syndrome (DSS) which has a high mortality rate.

DHF combined with a cirrhotic liver has been suspected in rapid development of Hepatocellular Carcinoma . Given the DEN virus is related to the Hepatitis C virus this is an avenue for further research as HCC is the top 5 leading Cancer cause of death outside of Europe and North America . Normally HCC does not normally occur in a cirrhotic liver for 10+ years after the cessation of the poisioning agent. DHF patients can develop HCC within one year of cessation of abuse.

This week, we will continue to come up with more survey questions and improve and edit our survey further to make it more neat and presentable so that our viewers will be able to give us their comments and feedback on the topic that we are researching on. 

Malcolm Wu Week 6

Today, we focus on the survey skills in creating the survey table and thinking of survey questions to ask the people of Singapore. We also have to go around interviewing about 20 people which includes students, teachers and the people that work in the civil service and adults by the end of this week.Our survey questions need to have a balance of open-ended questions and multiple choice. 

Malcolm Wu Week 5

Malcolm Wu Week 5

In week 5, my team and i decided to get down to work and finish up the project planner A which Justin did and the survey questions. We also did the distribution of work and research and i was supposed to do the research of the life cycle on dengue mosquitoes and such.

research - justin (how climate affects the breeding of mosquitoes)

Mosquitoes transmit dengue viruses. The virus replicates in the mosquito, this process takes one to two weeks from the time a mosquito imbibes infected human blood until the virus reaches the salivary gland of the mosquito and replicates to titer high enough to be transmitted. This incubation period in the mosquito is shorter if the ambient temperature is warmer. This is found most in mosquitoes that live near human dwellings, in flowerpots, water storage jars, cisterns, metal cans, discarded tires, and any other fresh water containers that people leave standing. The mosquito does not survive freezing weather and, thus, is primarily a tropical vector. One description of a dengue epidemic is that of Benjamin Rush in Philadelphia in 1780. The mosquito and dengue virus were imported to Philadelphia during the summer, but the mosquito did not live over the winter and the disease disappeared. The mosquito lives in the tropics wherever people live. The mosquito thrives in areas of high rainfall, but it also paradoxically thrives in desert areas because people often provide water containers for breeding. Mosquitoes cannot stand freezing weather, thus, it is limited to tropical and subtropical regions. Global warming is said tt oaffect regions in the tropics and has a greater effect at night. All these conditions are favourable for the mosquitoes as their breeding rate is always increasing. The risk of dengue outbreak is enhacned by two factors. Firstly, dengue multiplies more in high temperatures than in low ones. Secondly, the mosquito also grows rapidly in high temperatures than in low ones. This combination is condusive to a very short incubation period in the mosquito and rapid mosquito population increase. A short incubation in the mosquito along with rapid population increase inturn can lead to more rapid, and sometimes explosice transmissions in the human population. This prediction, however, should be accompanied by a caution. Warmer temperaturesalso leads to a shorter life span of the mosquito, and shorter life means less time to transmit the virus to another person.

Reflection 5 - Justin

This week we discussed more on survey questions, we also discussed a bit on who we were planning to ask the survey questions to. We decided to ask teachers, parents and friends. I have begun my research on how the climate effects the breeding of dengue mosquitoes. The topics of reserach have alreadly been deceided by the project planner. Malcolm has agreed to research the life cycle of mosquitoe while Gavin is researching the governments actions against the breeding of mosquitoes and finaly Yueh Hwa will researching about dengue fever and its symtomps. However i am not sure if we can meet the research deadline due to the approaching common test in the late feb to early march ...

Reflection 4 - Justin

Having problems with signing in lately, so this is a rather late post.
Last week, we were required to complete project planner A and B and also come up with survey questions. Well both Yueh Hwa and I have completed the project planners so we are left with survey questions and research. However due to comming exams i do not think we will be able to complete it so soon.

Today we discussed more on the survey questions and when we would get together for more group work outside school. The main topic is about wether the government had done enough for Singapore against dengue and wether anything more should be done. I think we should be able to complete the project rather soon.
