The purpose of this study was to evaluate the diversity of food intake among Korean college students of a nutrition education course through the internet. Subjects were 796 nation-wide college students (male 278, female 518). A dietary survey collected from 3 day-recalls were analyzed by the Computer Aided Nutritional Analysis Program. Diet variety was assessed by DDS (dietary diversity score), MBS (meal balance score), and DVS (dietary variety score). The foods consumed in largest amounts were rice (54.42 g), citrus fruit (36.41 g) and milk (30.91 g). The foods consumed most frequently were rice (65.28%), garlic (63.65%) and salt (63.64%). The average food intake was 1325.3 g (male 1420.6 g, female 1274.1 g), with vegetable and animal food comprising 78.5% and 21.5% of total food intake, respectively. The consumption of the major five food groups comprised DDS, and 66.0% (male 56.1%, female 71.3%) of subjects had a DDS of 5 and 27.4% (male 33.5%, female 24.1%) of subjects had a DDS of 4..Groups most frequently missed were dairy products (56.5%) and fruits (41.6%). The average of MBS were 10.88 (11.61 in Seoul, 11.03 in Kyungsang, 10.88 in Chungcheong, 10.85 in Incheon, 10.57 in Kyunggi) in male and 11.08 (11.47 in Kyungsang, 11.20 in Seoul, 11.18 in Kyunggi, 10.82 in Chungcheong, 10.64 in Incheon) in female. Male students in Seoul (18.2) and female students in Kyungsang (18.6) had the greater number of consumed food items. Subjects who had higher DDS had significantly higher DVS (p < 0.001). Based on these results, the food intake of the subjects regarded as not adequate, especially with regards to the dairy and fruit groups. Considering their nutritional characteristics, dietary guidelines as well as education should be made to improve the food intake and include various foods in their diet.

This experiment was conducted to evaluate the effects of dietary protease on growth performance, blood constituents, and carcass characteristics of growing-finishing pigs. A total of 48 growing pigs (initial body weight, $34.8{\pm}0.62kg$) were randomly assigned to 2 dietary treatments (6 pigs/pen; 4 replicates/treatment). The treatments were a diet based on corn and soybean meal (CON) and CON supplemented with 0.01 % of protease (PRO). Pigs were fed respective dietary treatments with a 2-phase feeding program for 12 weeks. Pigs fed PRO had higher average daily gain (ADG; phase I, 866.38 vs. 821.75 g/d; overall, 910.96 vs. 866.30 g/d; p < 0.05) and gain to feed ratio (G:F; phase I, 0.345 vs. 0.363 g/g; p < 0.05) than those fed CON. However, there were no differences on blood constituents and carcass characteristics between CON and PRO of growing-finishing pigs. In conclusion, dietary protease supplementation in the typical diet for growing-finishing pigs improved growth rate.

Objective : The aim of the present study is to examine hepatic lipid-lowering and anti-inflammatory effects of silymarin combined with Jakyakgamcho-tang on non-alcoholic fatty liver disease in a high fat diet-induced obese mice model. Methods : C57BL/6 mice were divided into four dietary groups: (1) Normal, (2) Control (60% high-fat diet), (3) Control + silymarin 50 mg/kg/day (Silymarin), (4) Control + Silymarin 50 mg/kg/day + Jakyakgamcho-tang 100 mg/kg/day (SPG). After 12 weeks administration, mice were sacrificed and lipids and inflammation-related biomarkers were analyzed liver and plasma. Results : Silymarin and SPG treatments significantly lowered body and liver weights compared to the Control. Serumlipids (triglyceride (TG), total cholesterol) and pro-inflammatory cytokines (tumor necrosis factor alpha, interleukin 1𝛽, and IL-6) concentrations were significantly lowered in the Silymarin and SPG groups than the Control group. Silymarin and SPG treatments suppressed hepatic TG level and hepatic lipid droplets compared to the Control. Theses two treatments significantly increased hepatic kinase B1 and AMP-activated protein kinase protein levels, and significantly decreased hepatic key lipogenic enzymes (acetyl-CoA carboxylase, fatty acid synthase and stearyl coenzyme A desaturase 1) protein levels than the Control. SPG also significantly increased hepatic fatty acid oxidation-related protein (peroxisome proliferator-activated receptor alpha and uncoupling protein 2) levels than the Control. Conclusions: Silymarin and SPG suppressed hepatic lipid accumulation by regulating hepatic protein expression, and lowered blood pro-inflammatory cytokines concentrations though the synergic effect of silymarin and Jakyakgamchotang was not clear.

Maple syrup urine disease (MSUD) is an autosomal recessive metabolic disorder caused by a deficiency in branched chain α-keto acid dehydrogenase (BCKAD). Between 1997, when Korea's MSUD case was first reported, and 2023, 14 cases were reported in the literature. 29% of the cases experienced developmental delay, and 29% expired. The prevalence of MSUD in Korea was estimated to be 1 in 230,000. Of 21 MSUD patients currently being treated at the Korea Genetics Research Center, 19 were detected through newborn screening program, and 2 were diagnosed by the symptoms. 14 MSUD patients had confirmed genetic mutations; 6 (43%) were BCKDHA and 8 (57%) were BCKDHB. In one case, a large deletion was observed. 4 patients had leucine levels above 2,000 (umo/L), and post-dialysis diet therapy was initiated in the newborn period. No patient required further dialysis as diet therapy and regular monitoring proved highly effective. Most MSUD patients were growing normally; weight and height growth were above the 50th percentile in 76% of the cases while BMI values were higher than normal in 71% of cases. Developmental delays were observed only in 2 cases (10%) and anticonvulsant use in 3 cases (14%). With newborn screening available to all Korean infants, early diagnosis and intervention should allow most patients to remain asymptomatic. However, ongoing surveillance, dietary management and continued patient compliance as well as rapid correction of acute metabolic decompensations remain critical to a favorable long-term prognosis.

The aim of this study is the development of a fee - based model day care center for the elderly by inquiring into the current condition of facilities in America and in Korea, and in surveying the opinion of domestic elderly about day care facilities. A field trip to U.S. day care services was held between July 5 and July 15 in 1997, and an on-the-spot study for domestic facilities took place during March in 1998. Our research reveals that the overall supply of day care facilities can not meet future demand in terms of quality and quantity. Therefore a model must be created for day care centers of a that consists of a director from a professional group. an adequate environment, and a standardized in order to offer a qualified public health service linked to the home and community in Korea. The director of a day care center is a critical variable in determining the quality of service. Professional skills related to the needs of the elderly and the person's quality of service should be considered in appointing director for the center. This study belleves that a professional nurse should be the director of a day care center. The operating environment of a day care facility should be made up of considerable space comparable to the number of residents, should be in a comfortable and safe location, and should have equipment that provides a qualified, safe service to the elderly. Our model is designed for 20 persons and allocates 4 Peng per person. This model is comprised of a reading room. a craft room, a health room, a room for physical therapy, a dining room, a staff office, and a multi -purpose room connected to other rooms. Day care service should be a comprehensive service program meeting the multidimensional needs of the elderly. A comprehensive service program needs a team of various professionals made up of the elderly family, participants, nurses, social workers, physical therapists, nutritionists, and medical doctors. The program will also include health care service, physical therapy, speech therapy. diet, occupational therapy, transportation service, health and an education program, etc. In conclusion, a model of a day care center is developed with the following components: a professional director and an environment and program, that considers the physical, mental, and social characteristics of the elderly. A model should also motivate self-reliance self-fulfillment in the elderly in order to fulfill their health needs and to prevent isolation from society and mental depression. Furthermore, This facility will be a beneficial factor in reducing a family's burden on caring for the elderly that includes unnecessary hospital expenses. The following is a suggestion based on results this study: A service program should be developed to fit the conditions of the elderly in Korea by specifically analyzing the needs of the elderly.

Metabolic syndrome is a cluster of metabolic risk factors associated with increased risk of cardiovascular diseases. Recently, the prevalence of metabolic syndrome has increased in Korea. The aim of this study was to develop a Healthy Han-sik Nutrition Education Program (HHNEP) based on commonly recognized Korean foods in order to decrease metabolic syndrome risks. The target population of the HHNEP is adults with metabolic risk factors. The initial version of the HHNEP was developed based on a review of literature and various dietary guidelines by expert committees as well as the results of a survey on the perception of common Korean dishes and foods as Han-sik. The focus group discussion conducted of nine participants from the target population. After minor modification, the final version was developed. The contents included five sections: 1) aims, 2) introduction of Korean Food Guidance System, 3) cholesterol contents in food, 4) menu planning method using Han-sik, and 5) examples of daily Han-sik menu. The Han-sik list was selected based on the results from a Han-sik perception answered by 35 Korean adults aged 30-60 years using 517 frequently consumed Korean foods from the fourth Korea National Health and Nutrition Examination Survey. The nutrition education program was developed based on scientific evidence for the prevention of metabolic syndrome and focuses on tailoring education to an individual's dietary problems. Educational method was developed by a group of expert committees based in planned behavior theory and related research results. The education method consisted of assessment of current diet, four face-to-face nutrition education sessions over 8 weeks, and evaluation after 8 and 16 weeks. Initial version of nutrition education materials and methods was tested for feasibility by a select group of nine Korean healthy adults. Successful implementation of the program would include application by nutritional professionals at the health promotion center of the hospitals, public health center, and work sites. Intervention studies are needed to evaluate the feasibility and effectiveness of this program before large-scale applications.

청년기 여성들에게 널리 만연되어 있는 과잉 체중조절행동의 확산을 방지하기 위하여 체형에 따른 체중조절 행도의도를 예측하고자 하였다. 체중조절 행동의도를 예측하기 위하여 스트레스 과정 이론과 합리적 행동이론을 기반으로 한 연구모형을 만들고 이모형에 근거하여 결과를 분석하였다. 조사대상자는 대구시 소재하는 고등학교 대학교에 재학 중인 여학생 463명(고교생 337명, 대학생 126명)이었으며, 조사방법은 설문지를 이용하였고 통계처리는 SAS program을 이용하였다. 조사를 통해 얻어진 결과를 요약하면 다음과 같다. 1) 체형에 대한 불만족을 가져오는 스트레스 요인은 체형에 관계없이 모두 현재의 체형이 가장 큰 스트레스 요인이었고, 다음으로 체형에 대한 사회적 인식과 매스컴이 크게 영향을 미치는 것으로 나타났다. 자아존중 감은 모둔 군에서 인지된 스트레스에 영향을 미치지 못한 것으로 나타났다. 2) 다이어트 행동의도는 체형이 뚱뚱할수록 높았다. 3) 행동에 대한 태도에서 행동결과에 대한 신념은 저체중군에 비해 과체중군으로 갈수록 높게 나타났고, 행동결과에 대한 평가는 모든 군에서 긍정적인 평가를 나타내어 행동결과에 대한 신념이 태도에 대한 주요 결정변수인 것으로 나타났다. 4) 주관적 규범은 과체중군일수록 높은 값을 나타내어 다이어트 행동을 할 때 과체중군이 준거인의 뜻에 동의할 의사가 가장 높은 것으로 나타났다. 즉 과체중군이 정상체중 이하인 군 보다 준거인이 자신의 체중 조절 행동을 지지할 것이라는 신념이 높았다. 모든 체형군에서 남자친구의 경우에만 순응동기가 높았고 그 외의 준거인에 대해서는 과체중군에서 가장 높게 나타났다. 5) 저체중군에서는 인지된 스트레스와 다이어트 행동에 대한 태도가, 정상체중군에서는 다이어트 행동에 대한 태고, 인지된 스트레스와 함께 자아존중감이 행동의도에 크게 영향을 미치는 것으로 나타났다. 과체중군 에서는 특정한 요인이 다이어트 행동의도에 영향을 미치지 않은 것으로 나타났다. 자아존중감은 정상체중군에서만 영향을 나타내었고, 영양지식은 어느 군에서도 아무런 영향을 미치지 못했다. 이상의 결과를 종합하면 현재의 체형, 체형에 대한 인식, 매스컴의 영향 등이 체형에 대항 불만족이라는 스트레스로 인지되고, 이러한 이지된 스트레스와 체중조절 행동에 대한 태도가 체중조절 행동의도를 갖도록 하는 것으로 보인다. 특히 다이어트 행동에 대한 태도는 행동결과에 대한 신념이 주요 변수였음을 감안할 때 체형에 대한 불만족을 유발하는 요인들과 감안할 때 체형에 대한 불만족을 유발하는 요인들과 다이어트 행동 결과에 대한 신념이 주요 변수였음을 감안할 때 체형에 대한 불만족을 유발하는 요인들과 다이어트 행동 결과에 대한 신념이 체중조절 행동을 유발하는 주요 요인인 것으로 판단된다. 따라서 과잉 체중조절의 확산을 억제하기 위해서 현재 자신의 체형과 바람직한 체형의 기준에 대한 바른 인식을 갖도록 하는 것이 필요하다. 그리고 체형에 대한 사회적 인식이 중용한 스트레스 요인임을 감안하여 사회 전반에 만연되어 있는 바람직한 체형에 대한 인식의 변화를 위한 노력이 행해져야 한다. 또한 신념이 행동의도에 큰 영향을 미친다는 결과에 따라 다이어트 행동 결과에 대한 신념이 올바른 지식에 근거한 바람직한 신념으로 변화될 수 있도록 하여야 할 것이다. 또한 본 연구에서는 영양지식이 다이어트 행동의도에 아무런 영향을 미치지 않은 것으로 나타났다. 그러나 단기간에 실시한 영양지식의 교육이 행동의 변화까지는 영향을 미치지 않았으나 태도에는 영향을 미친 것을 참고하여 장기적인 목표를 갖고 영양 지식의 보급에도 힘을 기울여야 하겠다.
