A survey of an endemic locality at Songjung Ri, Ogok Myun, Goksung County, South Cholla Province for the prevalence of Clonorchis sinensis and Metagonimus yokogawai was primarily done on 53 residence before medication using formalin-ether concentration method of stool examination. After praziquantel medication of all the clonorchiasis patients, 64 humans consisting 82.1% of total inhibitants and including 84.9% of primarily surveyed residents were secondly surveyed after 2-year post-treatment to evaluate the prevalence and reinfection. The prevalence of clonorchiasis was decreased from 35.8% before medication to 10.9% after medication(P<0.01), indicating this disease was not satisfactorily controlled although the rate was significantly lowered. The prevalence of metagonimiasis was dropped from 17.0% to 6.3% on post-treatment. In clonorchiasis cases, sex ratio showed no difference in both pre- and post-treatment, and mean age was the sixties after medication from the forties and fifties before medication, suggesting more aged people of both sexes were infected with this fluke. The reinfection of clonorchiasis and metagonimiasis following 2-year post-treatment was 15.8% and 25.0%, respectively. The proportion of reinfection among the egg positive cases was 50.0% in clonorchiasis and 100% in metagonimiasis. These findings mean that a high fraction of clonorchiasis and metagonimiasis was reinfected with these trematodes. In conclusion, to eradicate the C. sinensis and M. yokogawai in an endemic area, it should be preceded to control the reinfection of these parasites.

This paper is an in-depth case study to analyze integrated elementary science lesson planning and practical teaching by two teachers at an urban elementary schools. One is an experienced teacher and the other is a beginning teacher. For this study, researchers asked teachers to design 5 stages of lesson planning after sharing basic theories about the integrated science education. The first of the 5 lesson planning stages is curriculum analysis and choice of integrated science topic. The second stage is constructing the frame of integrated science lesson contents, and the third is drawing a diagram of the integrated science lesson development. The fourth stage is making a table of lesson plans, and the last stage is writing integrated science lesson plans. Then, the teachers implemented the lessons they created. They taught students one unit of science which is composed of 8 lessons. Difficulties that teachers meet during designing plans and integrated science class were analyzed. 5 staged lesson planning, video transcriptions, teacher interview about lesson planning and teaching, researchers' checklists, reports of inspection classes, teachers' self evaluation, and students interviews were used for this study. One of the significant results of this study is that both experienced and beginning teachers had many difficulties in deciding on time to teach and contents of science and other subjects, as well as selection and organization of whole topics of integrated science teaching. The beginning teacher especially had greater issues with developing definite teaching-learning strategy to conduct thoughts and views for integrated science at the whole unit and each lesson. However, the experienced teacher was using various teaching-learning strategies by utilizing integrated science teaching professionalism to develop students' integrated thinking ability during the instruction of other subjects. The outcomes of this study are that both teachers could deeply understand the need and value of integrated science education at the elementary school through planning and teaching 8 lessons, and that they could have self-confidence with development of teaching professionalism for integrated science teaching. It may be possible that this study could help the development of pre- and in-service program for improvement of integrated science teaching professionalism for elementary school teacher.

This study examined the development of a teacher's teaching practice and identified argumentation-specific pedagogical content knowledge (PCK) and the influence of the argumentation-specific PCK on teaching practice in an argumentation classroom. The teacher has a Ph.D degree in science education, a 19-year teaching career, and no experience in instructing in an argumentation classroom. The developed program consists of nine lessons regarding photosynthesis for 7th graders. The teacher participated in a collaborative reflection with researchers after each lesson once a week and five times in total, which lasted for thirty minutes. All of the lessons were video- and audio-recorded and the transcript of lessons and collaborative reflection, pre- and post-survey related to argumentation, and researchers' journals were analyzed. Analysis of the data showed that the teacher emphasized group interaction showing utterances of listening, evaluating arguments, counter-arguing/debating, and reflecting on argument process after the fourth lesson although the teacher focused on individual argumentation showing utterances of talking, knowing meaning of argument, and justifying with evidence in the first three lessons. Also, the argumentation-specific PCK, which was identified with the understanding of students, nature of argumentation and argumentation task strategy, also influenced the development of teaching practice. The teacher comprehended the students' challenges in argumentation, developed her understanding of the nature of argumentation from an individual plane to social plane, and demonstrated a deep understanding of the task strategy by voluntarily joining in modifying the argumentation tasks.

This correlational study sought to find the relationship among women's health status and the level of importance & performance of postpartal care. One hundred thirty three women who live in Seoul and rural area including hospitalized in a general hospital and midwifery clinic were studied from 1st April, 1998 to 25th April, 1998 for 25 days. Data analysis consisted of frequency, percentage, Pearson Correlation Coefficiency, t-test, ANOVA and Sheffe test as a post hoc, using SPSS. The results of analysis were as follows ; mean age of respondents was 31.9 years and mean number of children was 1.8. The most of family type was nuclear family and lived int apartment. Mean frequency of pregnancy was 2.7 times and most women delivered at local clinic, general or University hospital. Mean period of after delivery was 53.7 month. The level of importance and performance of traditional postpartal care (Sanhujori) was more higher than hospital postpartal care. The level of importance, performance of postpartum care and health status had significant relationship. The higher level of importance was, & the higher level of performance was higher, and the higher degree of health status. The factors related to health status were postabortal sahujori period after abortion, nuclear family, the evaluation of sahujori, whether women and followed the caregiver's advice well or not and whether they have physical symptoms or not, at the level of $5{\sim}0.1%$ of significance statistically. The factors related to the level of importance of postpartal care were the number of child, present health status and health status of pre-post of delivery, deliver place and the opinion of effective postpartum care method at the level of $5{\sim}0.1%$ of significance statistically. The factors related to the level of performance of postpartal care were delivery place, the opinion of whether they can do at the hospital or not and whether they have physical symptom or not at the level of $1{\sim}0.1%$ of significance statistically. In conclusion, this finding reconfirmed the relationship among women's health status and the postpartal care. It provides a challenge to the health professional caregivers to research continually and repeatedly and confirm the conceptual model of Sanhujori, reestablish effective and integrative postpartal caring system which contains oriental and western paradigm for women's life long health toward the 21C.

Background: This study aimed to evaluate the impact of a community-based health education and communication programme on reducing liver fluke infections caused by the consumption of uncooked fish among people in a high-risk area of Thailand. Materials and Methods: The study was quasi-experimental in nature, with three-stages. Stage 1 involved a situational and capacity analysis of designated communities in Khon Kaen province. This was followed by the development of a model for community-based health education and communication to prevent liver fluke infections among high-risk people, and, lastly, implementation and evaluation of the model were performed. Data were collected using both qualitative and quantitative methods. In total, 390 people were surveyed, and quasi-experimental and comparison groups, each with 90 people, were assessed between May 2011 and April 2012. Analysis was using statistical OR, 95 % CI, the Willcoxon matched pairs signed ranks test, the chi-square test, and the Mann-Whitney U test. Results: The findings showed that most respondents had a high level of knowledge and understanding of liver fluke disease (89.5%, 95% CI:86.0-92.4), and positive attitudes toward the prevention of the disease (94.4%, 95% CI:91.6-96.4). However, with regard to changes in consumption of uncooked fish, most respondents were still in the pre-contemplation phase (55.1%, 95% CI:50.0-60.1), followed by the contemplation phase, 22.6%. Furthermore, four factors were found to be associated with the consumption of uncooked fish - the consumption of alcohol (OR 4.16, 95% CI:1.79-9.65), gender (OR 3.17, 95% CI:1.53-6.54), smoking (OR 3.03, 95% CI:1.31-7.05), and age 40 years and above (OR 2.68, 95% CI:1.02-7.05). After nine months of the health education and communication programme using local media based on local wisdom, culture and persons, the results showed that, compared to the control group, members of the experimental group had a higher level of knowledge, a better attitude and lower levels of ill-advised consumption behaviour. Also, it was found that consumption of uncooked fish, by an assessment of the level of stage of change, was reduced. (p-value 0.002). Conclusions: The health education and communication programme developed as part of the study was effective in changing the consumption of uncooked fish. Therefore, this approach should be promoted in other high-risk areas in Thailand in the future.

The cost evaluation for voyage route planning in an ice-covered sea is one of the major topics among ship owners. Information of the ice properties, such as ice type, concentration of ice, ice thickness, strength of ice, and speed-power relation under ice conditions are important for determining the optimal route in ice and low operational cost perspective. To determine achievable speed at any designated pack ice condition, a model test of resistance, self-propulsion, and overload test in ice and ice-free water were carried out in a KRISO ice tank and towing tank. The available net thrust for ice and an estimation of the ice resistance under any pack ice condition were also performed by I-RES. The in-house code called 'I-RES', which is an ice resistance estimation tool that applies an empirical formula, was modified for the pack ice module in this study. Careful observations of underwater videos of the ice model test made it possible to understand the physical phenomena of underneath of the hull bottom surface and determine the coverage of buoyancy. The clearing resistance of ice can be calculated by subtracting the buoyance and open water resistance form the pre-sawn ice resistance. The model test results in pack ice were compared with the calculation results to obtain a correlation factor among the pack ice resistance, ice concentration, and ship speed. The resulting correlation factors were applied to the calculation results to determine the pack ice resistance under any pack ice condition. The pack ice resistance under the arbitrary pack ice condition could be estimated because software I-RES could control all the ice properties. The available net thrust in ice, which is the over thrust that overcomes the pack ice resistance, will change the speed of a ship according to the bollard pull test results and thruster characteristics (engine & propulsion combination). The attainable speed at a certain ice concentration of pack ice was determined using the interpolation method. This paper reports a procedure to determine the attainable speed in pack ice and the sample calculation using the Araon vessel was performed to confirm the entire process. A more detailed description of the determination of the attainable speed is described. The attainable speed in 1.0 m, 90% pack ice and 540 kPa strength was 13.3 knots.
