This study was conducted to investigate the changes of physical and psychological factors of obese children, obesity indices and blood serum levels, food habits and body and self-esteem after a weight control program. The results from this study were as follows: Participants of the study involved 20 boys (48.8%) and 21 girls (51.2%) totaling 41 children. Children's weight control experiences were 90.2% and parents' were 59.5%. Among methods of weight control, children and parents both used exercise and reduced amounts of meals. Sixty-one percent of the children had breakfast almost everyday. The reasons of skipping breakfast were having no time to eat by 44.4% and 50% of children watched TV while having a meal and they considered taste (55.3%) and nutrition value (21.1%) when choosing food. After the weight control program, the children's body fat percent (%) significantly decreased from 40.3% to 35.4% (p < 0.01). There was significant difference of boys and girls' hip circumferences (92.9 cm, 91.4 cm, p < 0.01) after the program but there was only a slight change in their WHR (0.91, 0.92). Girls' waist circumferences significantly decreased from 75.0 cm to 73.0 cm (p < 0.05) and there was a significant increase in HDL-cholesterol, 50.0 (mg/dL) to 55.2 (mg/dL), (p < 0.05). Knowledge levels of obesity significantly increased from 2.5 to 5.1 in the girls' cases (p < 0.001). Nonetheless, attitudes of weight control and food habits score had not changed a lot. After the program, both the boys and girls' body-esteem had significantly increased (p < 0.01) but self-esteem had not changed. These results suggest that a body weight control program must be included in nutrition education, exercise and psychotherapy to improve body and self-esteem of obese children.

This study was performed in an effort to standardize the quality of fresh-cut products. Here, consumers' perceptions of fresh-cut products were surveyed to determine the quality factors in preparing quality standards for fresh-cut products. According to the surveys, freshness was the most important factor for consumers when choosing fresh-cut products at the market. Secondary indicators of good quality, i.e., "sensory qualities," were determined to be vibrant color, clean taste, nice feel, neat presentation, etc., as well as knowledge of whether it was organically grown. Off-odors decreased a product's marketability. Likewise, the more wilted or brown it appeared, the less a product was desired. From the results, the quality control indices for fresh-cut products were derived as freshness, discoloration, off-flavor, uniformity, prohibition of adulteration by alien substances, packaging and labeling. The quality of fresh-cut lettuce samples was measured against three storage temperatures: $20^{\circ}C,\;10^{\circ}C$ and $5^{\circ}C$. Sensory quality evaluations revealed the following: produce stored at $20^{\circ}C$ lost its marketability in less than one day; produce stored at $10^{\circ}C$ lost its marketability in less than two days; on the other hand, produced stored at $5^{\circ}C$, maintained its marketability for six days. At these respective points, browning started to occur around cut areas, and increased gradually once it began. Vitamin C content decreased with storage time, but storage at $5^{\circ}C$ maintained vitamin content the longest duration. Finally, further examinations were performed on the sensory qualities of fresh-cut lettuce samples at four levels of increased browning. Up to the third level, the product score for marketability was 5.6.

본 연구는 동료(peer)에 대비한 학생의 상대적인 학업성취가 진로 결정에 어떠한 영향을 주는지를 살펴본다. 구체적으로 학교 내에서 학생들의 상대적인 수학 순위가 이과 선택에 미치는 영향을 분석하였다. 분석을 위해 서울시 소재 학생들의 패널데이터를 이용하였으며, 수학 성적을 통제하더라도 상대 순위가 낮은 경우 이과에 진학할 확률이 11%포인트 이상 감소함을 확인하였다. 높은 상대 순위는 여학생에게 추가적인 양의 이과 진학 효과를 나타내 상대 순위가 성별로 다르게 작용함을 보였다. 분석 결과에 따르면 상대 순위효과 중 약 12%만이 자신감과 같은 주관적 평가에 의해 설명되며, 이로 미루어보아 내신 성적을 통한 경로가 더 지배적일 것으로 추측할 수 있다.

This study was conducted to provide current information on dietary behaviors and dish preferences of elementary school children and to suggest guidelines for proper dietary behaviors. To accomplish study objectives survey was executed using the questionnaire for 420 fifth and sixth grade school children, chosen from schools in Kangwha-gun and East River District of Seoul. A questionnaire largely consists of categories including general characteristics, dietary behavior and preferences of the subjects for some dishes. Results showed 30％ of the subjects had breakfast irregularly. A majority of the subjects took Korean style dishes of cooked rice and soup for breakfast. fifty-eight percent of subjects had a regular meal time. Imbalanced diet(avoiding specific flood group thereby causing unbalance in nutrient intake) habit group was estimated to be 47.3%. Twenty one percent had a habit of overeating. In choosing the snack, taste was considered to be a more important factor than nutrition. Advertisement of the snack was shown to be one of the Important factors in selecting the snack. The girls were more concerned about weight control than the boys. Also the girls were likely to rely on the diet to control weight since they exercised only in the physical c1ass while the boys exercised regularly. Generally, children liked animal protein containing foods and the preference for vegetables was low. In order to improve overall dietary behavior, systematic nutrition education programs reflecting sex difference should be developed. Dish preference data would be very useful in selecting substitutive dish for the s[hoof lunch menu to improve imbalanced diet. (J Community Nutrition3(2) : 69∼76, 2001)

Colorectal cancer (CRC) is now common in Thailand with an increase in incidence over time. Health authorities are planning to implement a nationwide CRC screening program using fecal immunochemical test (FIT) as a primary screening tool. This study aimed to estimate preferences and acceptance of FIT and colonoscopy, explore factors influencing the acceptance, and investigate reasons behind choosing and rejecting to screen before the program was implemented. Patients aged 50-69, visiting the primary care unit during the study period, were invited to join this study. Patients with a history of cancer or past CRC screening were excluded. Face-to-face interviews were conducted. Subjects were informed about CRC and the screening tests: FIT and colonoscopy. Then, they were asked for their opinions regarding the screening. The total number of subjects was 437 (86.7% response rate). Fifty-eight percent were females. The median age was 58 years. FIT was accepted by 74.1% of subjects compared to 55.6% for colonoscopy. The acceptance of colonoscopy was associated with perceived susceptibility to CRC and family history of cancer. No symptoms, unwilling to screen, healthy, too busy and anxious about diagnosis were reasons for refusing to screen. FIT was preferred for its simplicity and non-invasiveness compared with colonoscopy. Those rejecting FIT expressed a strong preference for colonoscopy. Subjects chose colonoscopy because of its accuracy; it was refused for the process and complications. If the screening program is implemented for the entire target population in Thailand, we estimate that 106,546 will have a positive FIT, between 8,618 and 12,749 identified with advanced adenoma and between 2,645 and 3,912 identified with CRC in the first round of the program.

The purpose of this study was to examine some of the most important factors for the development of information systems with today's fast-paced, ever-changing, and exciting information system environment. Especially, it was focused to investigate current information technology related to develop information systems, to find some important problems during the development process, and to suggest solutions for the problems. Case research methodology was used because a natural setting was needed and a focus was on contemporary events for this study. Similarly, research phenomena was not supported by a strong theoretical base. The case was the development of an integrated information systems in a specific university. Multiple-case designs were desirable, but single-case study was used because of limitations of site selection. Multiple data collection methods were employed in this study such as documentation, interviews, and direct observation. Some major problems were found during the system development. First, the schedule to complete a project was delayed over six months. Second, the system did not ensure to align organizational goals and information systems goals based on BPR (Business Process Reengineering). Third, there was a difficulty in evaluating request for proposal (RPR) returns and choosing a vendor. Finally, information technology is changing too fast. So, it was very difficult to get the transparency of new technology The study has suggested a few solutions: top management support, matching If planning with business planning, complete project plan and control, user participation, and training Finally, joint application development (JAD) is strongly recommended, which is a workshop that unites management, IT specialists, and knowledge workers to define and specify the logical requirements and technical alternatives for a proposed system.

Background: To obtain the maximum additional information about the prognosis of gastric cancer, we compared CA-50 with other previously defined markers. Materials and Methods: This hospital based study was carried out in the Department of Biochemistry of Nepalese Army Institute of Health Sciences between $1^{st}$ July 2012 and $31^{st}$ December 2012. The variables collected were age, gender, AFP, CEA, CA19-9, and CA50, assayed with ELISA reader for all cases. The cut off values for serum AFP, CEA, CA19-9, and CA-50 were 10 ${\mu}g/l$, 10 ${\mu}g/l$, 37 U/ml, and 20 U/ml, respectively according to the manufacturer's instructions. Approval for the study was obtained from the institutional research ethical committee. Results: Of the 40 examined patients, 13 patients had tumors located in the upper third of the stomach, 6 patients had tumors in the middle third, 16 patients had tumors in the lower third, and 5 patients had tumors occupying two-thirds of the stomach or more. The distribution of lymph node staging of the patients was as follows: 7 patients belonged to N0, 9 patients to N1 stage, 10 patients to N2 stage, and 14 patients to N3 stage. The statistical method of Cox proportional hazards using multivariate analysis also illustrated that tumor markers including CEA (2.802), CA19-9 (2.690), CA50 (2.101), were independent prognostic factors, as tumor size (1.603), and lymph node stage (1.614). Conclusions: The tumour markers now available, like CEA, CA 19-9 and CA 50, chiefly perceive advanced gastric cancer. The preoperative rise in those tumour marker level have a prognostic significance and may be clinically helpful in choosing patients for adjuvant management.
