BACKGROUND/OBJECTIVES: The current study examined trends in adherence to dietary recommendations and compared the levels of adherence between diagnosed and undiagnosed subjects with type 2 diabetes mellitus (T2DM) in Korea over the past 14 years. SUBJECTS/METHODS: Data were collected from the 1998-2012 Korea National Health and Nutrition Examination Surveys (KNHANES). Diagnosed diabetes was defined as giving a positive response to questions about awareness of the disease, a physician's diagnosis of diabetes, or medical treatment for diabetes, whereas undiagnosed diabetes was defined as having a fasting glucose level ${\geq}126mg/dl$. Assessment of adherence level was based on 6 components of dietary guidelines, considering meal patterns and intake levels of calories, carbohydrates, vegetable/seaweed, sodium, and alcohol. The participants received 1 point if they met the criteria for each of the 6 components, and the total possible score ranged from 0 to 6 points. Multivariate generalized linear regression was performed, taking into account the complex survey design. RESULTS: Among all diabetic patients aged 30 years or older, the proportion of diagnosed diabetes increased dramatically, from 40.9% in 1998 to 75.9% in 2012 (P for trend < 0.001). The overall adherence levels to dietary recommendations were low and did not significantly differ between diagnosed and undiagnosed subjects with T2DM for all survey years. Several improvements were observed, including increased adherence to maintaining sufficient vegetable/seaweed consumption (increased from 0.12 to 0.16 points) and limiting sodium intake (increased from 0.12-0.13 points to 0.19-0.24 points; P for trend < 0.001), while adherence to maintaining moderate alcohol consumption decreased. CONCLUSIONS: Analysis of data collected by the KNHANES indicates that Korean T2DM patients have poor adherence to dietary recommendations and maintenance of a healthy lifestyle, regardless of disease awareness. This finding suggests that development of practical, evidence-based guidelines is necessary and that provision and expansion of educational programs for T2DM patients is critical after diagnosis.

Since 1995, MOCT(Ministry of Construction and Transportation) and KOWACO(Korea Water Resources Corporation) have established the National Groundwater Monitoring Network in South Korea and also MOE(Ministry of Environment) has operated Groundwater Quality Monitoring network. Until 2001, 202 monitoring stations by MOCT and 780 monitoring wells by MOE have been constructed, measured groundwater level and analyzed water samples. Groundwater quality analysis has been conducted two times a year during last 6 years for all monitoring wells. The quality data has about 15 components including pH, COD, Count of Coliform group, and etc.. Trend analysis has been peformed for 6 components(Coliform, pH, COD, NO$_3$-N, Cl and EC) of water quality which are analyzed more than 7 times for total monitoring wells. Two test methods have been used ; Sen's test and Mann-Kendall test. These trend tests have been done at the 0.05 significance level. By the result of Sen's test, Count of Coliform group has either upward or downward trends at 4.3 percent of the monitoring points. pH does at 5.6 percent, COD does at 8.6 percent, Nitrate-Nitrogen does at 13.2 percent, Chloride does at 13.4 percent, and. EC does at 11.6 percent of the monitoring points. The exact causes of the groundwater quality trends are difficult to specify. Notable downward trends in nitrate at many monitoring points may be the result of reduction on some contamination sources. Potential causes include diminished agricultural areas, improvements in sewage treatment and a decrease in atmospheric deposition. Increase in chloride at many monitoring points may be the result of increased non-point source pollution such as road salting and runoff from sprawling paved developments and suburbs.

The Direct Instruction (DI) was applied to the learning-disabled in the basic engineering education (especially, physics education). The DI is specified as an educational method in which the instructor strongly controls during the whole process of the entire course. The tests of understanding, reasoning, memory, and problem-solving speed showed that 20 students (20%) out of random 100 students are learning-disabled. The average points of mid-term and final exams were 53.7% and 61.0% respectively for a certain 41-students class. However, in this class, for the lower point students who obtained less than 50% points, the average points of mid-term and final exams were 29.8% and 28.2% respectively, which showed decreased. From this lower point group, the 8 students (20% students of 41 students) were selected as the learning-disabled. With additional DI studies provided, the average points of mid-term and final exams for the learning-disabled were 18.9% and 25.5% respectively, which showed 6.6% increase that means the DI for the learning-disabled was effective.

The elderly population is rapidly increasing in South Korea, and interest in food development considering the Sasang constitution theory from oriental medicine and balanced nutrition is increasing. We developed the oriental medicinal porridges based on the Sasang constitution for the elderly. By Sasang constitutional medicine, Taeyangin has a large lung and small liver, and Soyangin has a large stomach and small kidney. Taeeumin has a small lung and large liver, and Soeumin has a small stomach and a large kidney. In this study, proper oriental medicine and food ingredients were identified, and a total of 12 oriental medicinal porridges were developed for 3 items by 4 Sasang constitution types. A single portion was developed based on about 600±66kcal, and the food ingredients were chopped. After cooking the menu developed based on the Sasang constitution, a sensory test was conducted. Five items, such as taste, appearance, aroma, texture, and overall preference, were evaluated on a 7-point scale. Sewage omegaenggul porridge among porridges for Taeyangin had the highest overall acceptance (6.17±0.7 points). Sukjihwang abalone black sesame porridge for Soyangin had the highest score(5.83±0.9 points). Sanyakyulmu hwangtae porridge for Taeeumin had the highest score(5.90±0.6 points). Ginseng chicken curry porridge among porridges for Soeumin had the highest overall preference in taste, appearance, aroma, texture, and overall acceptability (6.53±0.7 points). A limitation of this study was that the clinical trial could not be conducted on the elderly classified as Sasang constitution. In the future, the elderly will be able to have oriental medicinal foods according to the classification of Sasang constitution.

The research was conducted by center for children's foodservice management in Hanam-si. In order to improve job satisfaction, a survey was carried out by working conditions and job satisfaction in children foodservice employees working at child daycare centers registered from January to April. Ninety-five surveys out of 120 were collected, and 76 surveys were analyzed. Job satisfaction consisted of four elements, working environment, welfare, human relationships, and job-itself, analyzed by general characteristics. Pearson's correlation was carried out between job satisfaction and intention to change job by Likert 5 scales using SPSS statistic program. The percentages of child daycare centers owned by civilians was 52.6%, high school education level was 65.8%, permanent workers was 68.4%, and less than 1 year of foodservice was 34.2%. Average scores of job satisfaction were as follows: working environment scored 20.6 out of 25 points, welfare scored 10.3 out of 15 points, human relationships scored 17.5 out of 20 points, and job-itself scored 13.2 out of 15 points. The lowest job satisfaction average was 'I get paid fairly regarding the working hours and the amount of work' with a score of 3.6 points. Job satisfaction based on facility type, age, education level, and working period did not show significant differences, whereas hired status, numbers of foodservice children, and intention to change jobs showed significant differences. Hired status showed significant differences with welfare satisfaction (P<0.05). Numbers of children showed a significant difference with welfare and human relationship satisfaction (P<0.01, P<0.05). Intention to change job showed a significant difference with four elements of job satisfaction (P<0.05, P<0.01, P<0.01). In conclusion, to improve job satisfaction of children foodservice employees, working conditions and welfare satisfaction should be increased.

To investigate the effects of negative therapy at back meridian points on blood gas components and immune functions in male college students, this study was conducted on treatment types(abdomen group and back group) at three sampling times (before, post-2 wks and post-4 wks) by using $2{\times}3$ factoral design. Blood gas $components(pH,\;PCO_2,\;PO_2,\;HCO_3^-,\;O_2SAT,\;BE)$, red blood cell, hematocrit, hemoglobin, white blood cell and subsets(neutrophil, basophil, eosinophil. lymphocyte, monocyte), total T cells, helper T cells, suppressor T cells, Th/Ts ratio, total B cells, serum immunoglobulin levels (IgG, IgA, IgM, IgD, IgE), Cytokines(Interlukin$-1{\beta}$, -2, -4, 2 receptor, -6 and ${\gamma}$-interferon), NK cells were measured. Collected with data were analyzed statistically by repealed measured ANOVA. The pattern of change between two groups for hematocrit, hemoglobin, suppressor T cells, interleukin-6, ${\gamma}-interferon$, NK cells at post-2 weeks and BE, lymphocyte, basophil at post-4 weeks was significantly different(p<0.05) And also the pattern of change over time for ${HCO_3}^-$(2 wks vs 4 wks), WBC, neutrophil, lymphocyte(0 wks vs 2 wks and 2 wks vs 4 wks) was significantly different(p<0.05). In summary, these data suggest that negative therapy at back meridian points had an effect on blood gas components and immune functions in male college students because practicing negative therapy at back meridian points was not associated with changes of all blood gas components and immune factors but associated with changes of BE, hematocrit, hemoglobin, WBC. neutrophil, lymphocyte, interleukin-6. ${\gamma}-interferon$, NK cells.

The purpose of this study was to clarify the level of knowledge and the attitude about AIDS. according to high school students demographics. and the AIDS education effects in a week or 6 months. The data were surveyed from 74 bounding for university high school students and 98 vocational high school students from two counties in Chonnam. The data were collected from November 5. 1999 to May 24. 2000. using a 50-item Questionnaire. and analyzed by SPSS PC+ program for t-test. ANOVA, Repeated measure ANOVA, Duncan test. $x^2-test$ and pearson correlation coefficients. The result of study summarized as follows : 1. The knowledge score for AIDS was significantly higher in the group bounding for university. in the second grade group and the group who have drunken experience. The positive attitude score for AIDS was significantly higher in the group who have smoked experience. 2. After 1 week of AIDS education. the knowledge score for AIDS(15.02 points) was significantly higher than the one before the education(10.85 points) but after 6 months of AIDS education. the knowledge score for AIDS(12.30 points) was significantly lower than in a week(F=55.49. p=.000). 3. After 1 week of AIDS education. the positive attitude score for AIDS(3.54 points) was significantly higher than the one before the education(3.35 points) and after 6 months of AIDS education. the positive attitude score for AIDS was same the one in a week(F=7.85. p=.000). 4. We could find the significant correlation between the knowledge and the attitude for AIDS just only in a week(r=.249. p=.001). In conclusion. the knowledge score for AIDS had increased in a week of education on AIDS but it had decreased as time goes by since education. The increased positive attitude for AIDS in a week has maintained the same as time goes by since education. Therefore. It should be needed re-education on AIDS to students at proper time in order to get the aim of AIDS education. We have to develop variety education methods for educational effects. It should be included comprehensive social aspect such as a question of personal rights to increase the positive attitude for AIDS.
