Nonproprietary name may be used without restriction by the public at large and can be called common name, generic name. Nomenclature agencies exist in US, Great Britain, Japan and so on. The agencies maintain liaison with onε another in an effort to secure the wide adoption of thε most appropriate and universally acceptable designation for each drug. To prevent the confusion which arises when several nonproprietary names are used for a single drug, either in the same country or in several different countries, the WHO has assumed the responsibility of coordination existing nomenclature at the international level. In this study, the nomenclature for new drugs and the terminology to harmonize specifications for revision of Korean Pharmacopoeia (KP) were established.

A large number of investigations have shown that changes in nutritional condition affect endocrine status in avian species. Herein, recent findings including novel peptides discovered by the development of the techniques in the field of molecular biology have been reviewed. The insulin-like growth factors (IGF-I and IGF-II) found in chickens have been characterized and shown to be 70 and 66 amino acid polypeptides, respectively. Plasma IGF-I level is very responsive to nutrition, Le. varying dietary proteins and energy intakes, and food restriction. Plasma IGF-II concentration is altered by nutritional deprivation to a much smaller extent than plasma IGF-I concentration. Almost all of the serum and tissue IGFs are found in a complex composed of IGF and IGF-binding protein (IGFBP). In the chicken plasma, the major IGFBP differs from that in mammalian plasma. The proglucagon mRNA encodes glucagon and two glucagon-like peptides (GLP-I and GLP-2). The intracerebroventricular administration of GLP-l strongly decreased food intake of chicks, and it was indicated that the inhibition of food intake by GLP-l was associated with neuropeptide Y, which is one of the neurotransmitters reported to enhance food intake.

This study was performed to investigate the eating habit, body image, and weight control behavior by BMI in Korean female high school students. Data on the 16,574 subjects was obtained from the sixth Korea Youth Risk Behavior Web-based Survey (2010). Only 52.2% of the subjects had regular breakfast. The rate of skipping breakfast was higher in the underweight group than in the obese group, but the rate of skipping dinner was on the contrary to this. Underweight students had a higher intake frequency of fruits, fast food, instant noodle, and snacks than the obese groups. 3.5% of underweight students considered themselves to be overweight or obese. 53.4% of obese students considered themselves to be overweight. The experience of weight control increased according to BMI, but underweight students considered weight control as an effort to be slimmer. Meal restriction was used more frequently to control weight. The perceived stress level was higher in obese student, especially due to appearance. Therefore, an appropriate, integrated and personalized high school nutrition program should be established for proper body image perception and to develop the self-esteem of female high school students.

Fat and sugar reduced yellow layer cake system was developed with varied replacement level of 30%, 60%, and 90% for AD(amylodextrin) and 10%, 30%, and 50% for PD(polydextrose). Physicochemical and sensory characteristics were investigated and optimum replacement level was also decided using response surface methodology. Sample groups of PD10AD30 had significantly the lowest specific gravity and viscosity, indicating the stable batter system with high air incorporation. Sample groups with PD10AD90 showed the highest volume index and were not significantly different from those of the PD10AD30. Sensory results indicated that PD30AD30 were significantly the most springy and moist, and the least hard of all sample groups. Sample groups with PD10AD90 had the least adhesiveness value. To establish the optimum substitution level using RSM, the restriction level was set up as moistness over five point, hardness under five points, and adhesiveness under four points. The optimum substitution level was 20% for PD and 88% for AD.

A method for the isolation and purification of DNA from a red algae, Porphyra was innovated. The innovation of the method consists mainly of three steps that include sodium acetate treatment, chloroform extraction, and 0.2 volume isopropanol precipitation step. The sodium acetate treatment was designed to remove polysaccharide contamination, and the isopropanol step to remove proteins and salts contaminents. Genomic DNA,s of several species(for example, P. tenera, P. yezoensis, P. seriata, and P. pseudolinearis) was successfully isolated by the innovated method. The amount of DNA purified from one g of sample material with the innovated method was 53 g in average. The resulting DNA was characterized to include high molecular weight and showed no nuclease activity. The DNA was pure enough to be digested directly by various restriction enzymes without any difficulties. Porphyra DNA was pure enough and adequate for amplification reaction through the polymerase chain reaction (small nuclear rDNA PCR amplification).

Conventional foodservice system has been the most prevalent system across the country. However, all the elementary students throughout the country is not being provided with school lunch program because of the restriction on equipping school foodservice facilities. So commissary foodservice system was introduced to school lunch program in 1991. This study was designed to evaluate condition of existing major equipment including volume, probable useful life, and frequency of use and determine equipment improvements on conventional and commissary school foodservice systems. A questionnaire was developed and mailed to 87 dietians of conventional and 46 dietians of commissary school foodservices in Kyunggi-do. Response rates were 89.1% and 91.3%, respectively . Approximately one third of commissary foodservices were converted from conventional to commissary. Only 52.6% of conventional and 53.5% of commissary foodservice facilities/equipments have been desirable in quality and quantity. Capacity, functional ability, using frequency, and relationship with efficient work management were analyzed according to school foodservice system. Content analysis was conducted regarding to dietitians' opinions on foodservice facilities/equipment.

IPSKCDNA gene(1.8 kbp) encoding rat brain IP3K enzyme contained Not I restric site in open reading frame. The Not I sequence, GCGGCCGC, was converted to GCAGCCGC by site-directed mutagenesis. The mutated IP3KcDNA was digested with EcoR I and ligated with EcoR I-restricted psp72·Not2 vector. The resulting psp72 · Not2-IP3KCDNA was digested with the Not I restriction enzyme and then subcloned into the Not I -digested PZIP · NeoSV(X) mammalian expression vector. The PZIP · NeoSV(X) -IPSKCDNA was transfected into CCL39 hamster lung fibroblast cells. The efficiency of the expressed IPSKCDNA gene was significantly higher than expected generally, not only a mean 5-fold increase in the amount of enzyme, but also 16-fold increase in enzyme activity from tractsfected CCL39 cells by the method of Western blot using anti-lP3K antibodies. Both distribution of IPSK in various rat tissues and biochemical properties were discussed.

This study investigated the prevalence of Listeria monocytogenes in slaughterhouses, and determined serovars and genotypes, and antibiotic resistance of the isolates obtained from slaughterhouses and humans in Korea. Two hundred ninety samples were collected from feces (n=136), carcasses [n=140 (cattle: n=61, swine: n=79)], and washing water (n=14) in nine slaughterhouses. Eleven human isolates were obtained from hospitals and the Korea Center for Disease Control and Prevention. Listeria monocytogenes was enriched and identified, using polymerase chain reaction (PCR) and 16S rRNA sequencing. Serovars and presence of virulence genes were determined, and genetic correlations among the isolates were evaluated by the restriction digest patterns of AscI. Antibiotic resistance of L. monocytogenes isolates were examined against 12 different antibiotics. Of 290 slaughterhouse samples, 15 (5.17%) carcass samples were L. monocytogenes positive. Most L. monocytogenes isolates possessed all the virulence genes, while polymorphisms in the actA gene were found between carcass and human isolates. Serovars 1/2a (33.3%) and 1/2b (46.7%) were the most frequent in carcass isolates. Genetic correlations among the isolates from carcass and clinical isolates were grouped within serotypes, but there were low geographical correlations. Most L. monocytogenes isolates were antibiotic resistant, and some strains showed resistance to more than four antibiotics. These results indicate that L. monocytogenes are isolated from carcass and human in Korea, and they showed high risk serotypes and antibiotic resistance. Therefore, intensive attentions are necessary to be aware for the risk of L. monocytogenes in Korea.

{\beta}-carotene$은 비타민 A 활성형인 retinol로 전환되어 그 기능을 수행하는 영양소로 알려져있지만 {\beta}-carotene$ 자체로서의 생리적, 영양학적 중요성이 부각되고 있다. 본 연구에서는 {\beta}-carotene$을 수준별로 공급하여 체내의 지질대사와 항산화 효소의 활성에 미치는 영향을 살펴보고자 계획되었으며 얻어진 결과는 다음과 같다. 간 미토콘드리아에서의 과산화지지르이 함량은 제한군과 과잉 공급군이 다른 처리군들에비해서 상대적인 증가를 보였고 BC 2군에서 가장 낮은 값을 나태내었다. SOD의 활성은 {\beta}-carotene$ 제한군이 공급군에 비해서 유의적으로 증가하여 SOD 활성에 대한 {\beta}-carotene$의 조절효과를 보여주었고 catalase와 GSH-Px의 활성에 대한 {\beta}-carotene$의 조절효과를 보여주었고 catalase와 GSH-Px의 활성은 과잉 공급군의 경우 가장 낮은 값을 보여주었다. {\beta}-carotene$ 공급에 따른 지질 함량의 변화는 간의 경우에 총지질 함량은 {\beta}-carotene$ 공급에 따라 감소하였고 중성지질은 전 군에서 유의적인 차이가 보이지 않았으며 인지질은 BC 2군과 BC 3군에서 유의적으로 낮은 값을 보였다. 콜레스테롤 함량은 BC 1군에서 가장 낮은 값을 보였다. 혈장에서는 {\beta}-carotene$ 공급이 증가함에 따라 중성지질의 함 은 증가하는 경향이었고 HDL-콜레스테롤은 BC 4군에서 가장 낮은 값을 나타내었다. HDL-콜레스테롤 함량비는 {\beta}-carotene$ 공급에 따라 증가되었으나 과잉공급군에서 제한군과 같은 수준으로 감소되었다. 이상의 결과에서와 같이 12,000mg의 {\beta}-carotene$을 급여한 군에서는 지질대사 관련효소 활성도와 체내 지질함량이 적정량을 급여한 군에 비해 크게 변화하였으나 10~1,200mg을 급여한 실험군들 사이에서는 큰 차이를 나타내지 않아 {\beta}-carotene$의 정량적 평가를 위한 지속적인 연구가 필요하다고 본다.하다고 본다.
