The purpose of the survey was to clarify the clinical features and management of the anorectal malformations (ARM) in Korea. Twenty-seven members of the Korean Association of Pediatric Surgeons were surveyed. The members completed a case registration form for each patient during the two years period of 1996-1997, and a questionnaire that contained their management preferences for primary and complicated patients. Twenty-four members of the 22 institutions registered 295 cases of the ARM, and 27 out of 34 members (77.1 %) responded to the questionnaire. The patients were classified by the Wingspread classification of ARM(1984). The case registration form was a modification of Wingspread workshop for the postoperative assessment and case registration. The male to female ratio was 1.7 : 1. The average number of patients per surgeon was 6.1 cases per year. Prematurity(< 36 weeks) was present in 1.9 % of cases and low birth weight (< 2.6 Kg) in 12.1 %. Among 187 male patients, 62 were high(H) type, 29 intermediate(l) type, 88 low(L), and 8 unclassified. In female, there were 2 cases of cloacal anomalies(C), 4 H type, 30 I type, 66 L type and 6 unclass ified. For male, 87.9 % of H and I type were operated by the Pena procedure, but only 7.9 % in L types. In female, all of C, H and I types, and 40.9 % of L type were done by the Pena procedure. One case expired (MR; 0.003%) as a result of surgical complication. Over-all complication rate was 12.5 %. Among 6 cases of reoperation, 4 were failed Pena procedures. Among 140 colostomies sigmoid colon was utilized in 75.7%, and loop colostomy was commonly used. Ten surgeons prefered primary maturation of the stoma. In conclusion, posterior sagittal anorectoplasty is popular for high types of ARM in this country, but considerable number of patients are still suffering from failed operations. For better understanding and analysis, necessity of prospective study by new classification was discussed.

Red spotted grouper, Epinephelus akaara is distributed in the south and west coasts of Korea. The natural stocks of the fish are decreasing sharply year by uear because of reckless overfishing. This research was carried out to understand general informations on maturation, sex composition and sex-reversals of the fish. Annual fishing uields of red spotted grouper in the castal area of Byonsan Peninsular of Kora decreased over 10% from 1992 to 1994. The main fishing season was from May to July with fishing gear of Hand-lines. Gonadosomatic index (GSI) and condition factor were highest on early and late July, respectively, thus main spawning reriod was assumed from late July to early August. The relationship between total length (X) and body weight (Y) for wild adults was represented as a regression, Y=$0.0169X^{2.9705}$, ($r^2$=0.96). Frequency of sex of wild red spotted gouper showed that the number of female below 38cm in total length was more than that of male, and hermaphrodite mainly occurred from 28cm to 32cm in total length the frequency of male and female were almost same. Also hermaphrodite occurred mainly between 25~29cm. Sex reversal ration of the adults reared in a tank for a year with different sexual compositions revealted that the frequency of female reversed from male was more than that of male reversed from female at 1:1 and 1:2 stocking densities of female and male, respectively. Also, about 20% of female was reversed to male when all females were reared. And the size of the fish reversed to male was larger than that of non-reversed female.

Background: Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation that is not fully reversible. COPD has systemic effects, such as skeletal muscle dysfunction and abnormal weight loss. It also has been suggested that COPD is related to other chronic disease, such as cardiovascular disease, osteoporosis, and anemia. The aim of this study was to evaluate a symptom questionnaire and laboratory findings in subjects with air flow limitation. Methods: We evaluated a symptom questionnaire and laboratory findings in subjects with airflow limitation detected by spirometry in conjunction with the Second Korean National Health and Nutrition Examination Survey. A total of 9,243 adults over the age of 18 were recruited. Among the adults, we finally analyzed 2,217 subjects who met the acceptability and repeatability criteria of spirometry, showed normal findings on chest radiography, and were older than 40 years of age. Results: There were 288 subjects with airflow limitation as determined by spirometry. The frequency of respiratory symptoms such as cough, sputum and wheezing were significantly higher in subjects with airflow limitation (p <0.01). Hemoglobin and hematocrit levels were higher in subjects with airflow limitation (hemoglobin level 13.98 mg/dL vs. 13.62 mg/dL, hematocrit 42.10% vs. 40.89%; p<0.01). The HDL cholesterol level was lower in subjects with airflow limitation (44.95 mg/dL vs. 45.60 mg/dL; p<0.01). There was no significant difference in the total cholesterol, triglyceride, blood urea nitrogen, creatinine, and fasting glucose levels. Conclusion: In subjects with airflow limitation, prevalence of respiratory symptoms was higher than in normal spirometry subjects and the levels of hemoglobin and the hematocrit were higher. The HDL cholesterol level was lower in subjects with airflow limitation.

The purpose of the study was to provide baseline information that could encourage consumers and establish the direction of development for sprouts and leafy vegetables. A survey on the consumption and preference for sprouts and leafy vegetables of 823 people over 20 years of age in Seoul and Gyeonggi province was conducted. The preference for sprouts was higher in men ($3.75{\pm}0.96$) than in women ($3.64{\pm}0.84$), whereas the preference for leafy vegetables was higher in women ($4.06{\pm}0.74$) than in men ($3.88{\pm}0.90$). Based on age, the respondents in their 40s or above had high preferences for sprouts and leaf vegetables due to the importance that they accorded to health and nutrition (p<0.01). The sprouts and leafy vegetables were purchased mainly for their high nutritional value. The purchase frequency of once a month or more for leafy vegetables (82.7%) was higher than that for sprouts (57.1%). The consumers purchased sprouts and leafy vegetables mainly from a large discount store. The respondents in their 20s showed the highest percentage of purchasing from a local store whereas the older ones showed a high preference for traditional markets. The reason for the choice of the place of purchase was convenience. The freshness and price were important factors in the consumption of sprouts and leafy vegetables. In the case of leafy vegetables, the consumers preferred to buy them using the conventional weight measurement system rather than in small packages. On the other hand, mixed small packages were preferred for sprouts. The purchase frequency was correlated with the preferences, need for improvement and purchase intent for sprouts and leafy vegetables. The aspects that require improvement for producing high-quality sprouts and leafy vegetables were the nutritional and functional properties. To increase the consumption of sprouts and leafy vegetables, there is need for variations and improvement of the quality and safety of the products.

The effects of Opuntia ficus-indica var. saboten powder on the growth of lactic acid bacteria (LAB) were investigated in order to explore the possibility of manufacturing fermented milk containing the powder. Differences in pH, acidity, LAB counts, viscosity, and sensory evaluation were measured. Also the effects of dietary supplementation on the growth of piglets were evaluated by feeding fermented milks containing 0.1%, 0.2%, 0.5%, and 1.0% Opuntia ficus-indica var. saboten powder. Levels of pH, titratable acidity, viable LAB counts and viscosity were significantly different by the addition of the powder. When fermented milks containg 0.1%, 0.2%, 0.5% and 1.0% Opuntia ficus-indica var. saboten powder were kept at $4^{\circ}C$ for 30 days, viable LAB counts remained high after 30 days of storage. The effects of dietary supplementation of 0.2% Opuntia ficus-indica var. saboten fermented milk were investigated by examining piglet growth rate and fecal ammonia gas release. The piglets were fed 100g/herd of the fermented milk for 14 days. Average daily body weight gain was significantly (p<0.05) improved (110%) with dietary supplementation of the fermented milk, compared to a control group. More over, fecal ammonia gas emissions were reduced by dietary supplementation of the Opuntia ficus-indica var. saboten fermented milk. Sensory evaluation results showed that the samples containing 0.1% and 0.2% Opuntia ficus-indica var. saboten powder had the most parameters similar to those of the control.

This paper reviews the present situation of Triticale cultivation and examines the potentiality of contribution to livestock as well as poultry sector in Bangladesh Agriculture. Triticale is a human-made cross between rye and durum wheat that has the ability to produce quality green fodder, and then re-grow after first and second cutting to produce grain. In Bangladesh, it is a non-traditional cereal that grows well during the cool and dry Rabi season (November-March) when fodder and feed scarcity is a major limiting factor for ruminant livestock. In Bangladesh Triticale was started to grow in the late Ninety's. The scientists of Bangladesh Agricultural Research Institute (BARI) were first introduced triticale in Bangladesh. Still now the situation of Triticale is grown as fooder and feed in Bangladesh within the scientists under trial. High quality grass fodder was obtained by cutting green triticale plants twice, at 35 and 50 days after seeding, while later the ratooning tillers produced grain to a yield of 1.1-2.4 t/ha of grain for poultry feed or human food. Triticale straw was twice as nutritious as rice or wheat straw and its grain contained more protein than other cereals. Researchers and farmers have also successfully made triticale hay and silage from a mixture of triticale green cuttings, rice straw and molasses. A feeding trial at Bangladesh Livestock Research Institute(BLRI), Savar station showed a large(46%) increase in cow live weight gain and a 36% increase in milk yield (but no change in milk quality or dry matter intake) in cows fed triticale silage compared with those fed rice straw over a period of nine weeks. In another feeding trial, it was found that triticale grain was a good replacement for wheat in the feed blend for chickens in Bangladesh. So it will be a good chance to alive our livestock as well as poultry sector if triticale enters to our existing cropping system as fodder cum grain. The challenge in Bangladesh is to identify fodder technologies that match existing small-scale farmer cropping patterns without needing major inputs or increasing risks. Preliminary field experiments revealed that triticale is a crop with good potential to produce quality fodder and grain for small scale farmers in Bangladesh.

In order to determine the effective concentration, 2, 7, and 14 brix black garlic extracts (BGE) were fed to restraint stressed rats and the lipid metabolism was analyzed. The dietary intake of the 14 brix BGE-fed group was $547.64{\pm}13.99$ g/4 weeks and it was significantly higher than that of the control group. The weight of all organs from the all BGE-fed groups showed no significant differences. While BGE concentration increased, BGE-fed groups tend to have low content of blood glucose. It was the lowest in the 14 brix BGE-fed group ($121.32{\pm}3.50$ mg/dl). Total cholesterol content was $54.54{\pm}1.63{\sim}65.84{\pm}2.61$ mg/dl. Total cholesterol content of the 14 brix BGE-fed group was the lowest and, in addition, lower than the normal group. Triglyceride content of serum showed the same tendency. HDL-cholesterol concentrations of the restraint stressed control (RSC) group were significantly higher than those of 7 and 14 brix BGE-fed groups. LDL and VLDL-cholesterol contents showed contrary results. GOT, GTP, and ALP activity of serum were lower when BGE concentration was higher. It is expected that BGE has a liver protective activity. In the liver, total lipids and triglyceride contents were significantly lower in BGE-fed groups than in the ISC group. However, total cholesterol content showed no significant difference between groups. TBARS content in liver of the 2 brix BGE-fed group was not significantly different than control, while 7 and 14 brix BGE-fed groups were lower than control. Glycogen content in the liver was only significantly lower in the 14 brix BGE-fed group than in the RSC group. Findings indicate that feed of BGE over 7 brix contributes to resolving the restraint-stressed rats by improving the lipid metabolism and liver protective activity.

Peach (Prunus persica) has been recognized as a food allergen for over 20 years. However, there is little information about cross-reactivity with other foods. The aim of this study was to research cross-reactivity of Korean cherry and hot pepper on patients allergic to peach and its stability by digestive enzyme treatment. Peach, Korean cherry, and hot pepper proteins were extracted and separated by Tricine-SDS-PAGE analysis. The protein extracts had a wide range of molecular weight, from 3 kDa to more than 26 kDa, and displayed different patterns of protein bands on Tricine-SDS-PAGE. Peach allergic patients' sera were used to detect the allergenic protein in three samples. Three peach allergic patients' sera reacted strongly with 9 kDa protein of peach, which was the expected lipid transfer protein (LTP) as the major allergen of peach and was detected with anti-LTP1 polyclonal antibody. However, the reactivity of the 23 kDa protein in Korean cherry and hot pepper protein was stronger than that of the 9 kDa protein. The stability of protein extracts on digestive enzyme treatment was examined using simulated gastric fluids (SGF) and simulated intestinal fluids (SIF), in which digestive enzyme stability is one of the characteristics of allergen potentially causing food allergy. Findings confirmed that allergenic proteins in peach, Korean cherry, and hot pepper were not completely digested by SGF and SIF treatments from results of SDS-PAGE analysis. These results confirmed that Korean cherry and hot pepper might cause cross-reactivity in peach allergic patients, and its allergenic proteins have stability against digestive enzymes.

An evaluation of the influence of nutritional health camp for in obese elementary students was assessed. Anthropometric measurement, 24-hour recall of dietary intake, MMTIC(Murphy-Meisgeier Type Indicator for Children) and questionnaire response(nutritional knowledge, nutritional attitude, and self-satisfaction) was documented in 43 obese elementary students(29 boys and 14 girls). The mean age of the elementary students was 11.2 years. The mean height, body weight and obesity index was 144.7 cm, 55.4 kg and 41.0% in boys, and 136.1 cm, 45.2 kg, 40.0% in girls. The mean energy intake was 1,522.4 kcal in boys and 1,494.9 kcal in girls. The subjects taking less than estimated average requirement(EAR) for vitamin ${B_2}$, folate, vitamin C and calcium was over 70%. A considerable number of students(65.1%) showed U band(undetermined character). The students demonstrated a propensity towards increased average nutritional knowledge and self-satisfaction after attending the nutritional health camp. In addition, a significant increase in average nutritional attitude was observed(p<0.001). The results of this study suggest that nutritional health camp positively influenced the nutritional attitude of elementary students.

This study proposes a new methodology for future water balance projection considering climate change by assigning a weight to each scenario instead of inputting future streamflows based on GCMs into a water balance model directly. K-nearest neighbor algorithm was employed to assign weights and streamflows in non-flood period (October to the following June) was selected as the criterion for assigning weights. GCM-driven precipitation was input to TANK model to simulate future streamflow scenarios and Quantile Mapping was applied to correct bias between GCM hindcast and historical data. Based on these bias-corrected streamflows, different weights were assigned to each streamflow scenarios to calculate water shortage for the projection periods; 2020s (2010~2039), 2050s (2040~2069), and 2080s (2070~2099). As a result by applying the proposed methodology to project water shortage over the Korean Peninsula, average water shortage for 2020s is projected to increase to 10~32% comparing to the basis (1967~2003). In addition, according to getting decreased in streamflows in non-flood period gradually by 2080s, average water shortage for 2080s is projected to increase up to 97% (516.5 million $m^3/yr$) as maximum comparing to the basis. While the existing research on climate change gives radical increase in future water shortage, the results projected by the weighting method shows conservative change. This study has significance in the applicability of water balance projection regarding climate change, keeping the existing framework of national water resources planning and this lessens the confusion for decision-makers in water sectors.
