  • 20 species of plants were extracted with Methanol and were investigated for DPPH radical scavenging activity and ABTs free radical scavenging activity to quest anti-oxidation ability depending on the proton beam irradiation quantity. In the proton beam irradiation, 15 species's activities increased but among them, Pharbities nil Choisy decreased at 10 KGray and 4 species' activity didn't change at all. In hydrogen ion radical elimination activity, Ulmus macrocarpa (84 %) showed the highest and Pharbitis nil Choisy showed 6 % decreasing at more than 1 KGray. By comparison with untreated $IC_{50}$ value, the beam-treated $IC_{50}$ value increased 6.3 times for Dioscorea batatas Decne. at 1 KGray, 2.1 times for Trichosanthes kirilowii Max., and 2.8 times for Dioscorea batatas Decne. at 5 KGray. In ABTs free radical elimination activity, the activity increased 60 % for Terminalia chebula Retzius compared with untreated one. Besides, the beam-treated $IC_{50}$ value increased 2 times for Gray Ephedra sinica Stapf, 2.5 times for Terminalia chebula Retz. and 2.4 times for Arctium lappa Linne at 1 KGray.

  • 참가자미, Limanda herzensteini는 가자미목 (Pleuronectiformes), 가자미과 (Pleuronectidae)에 속하며, 우리나라의 동해, 일본의 세토내해 이북, 중국 및 사할린 근해에 분포하는 어종이다. 본 종은 연안정착성 어종으로 동해안에서 낚시 및 저인망 어업에 의해 어획되는 산업적 가치가 큰 고급어종이며, 저수온에 강하여 한류성 해역에서의 양식 가능성이 매우 높다고 할 수 있다. 또한 최근에는 참가자미의 자원량 감소가 두드러지고 있으므로 자원증강이 절실히 요구된다. 이 연구에서는 주 어획지역인 강원도 주문진 인근해역에서 1998년 9월부터 1999년 10월까지 자연산 참가자미의 연간 생식소중량지수의 변화를 조사 하였으며, 조직학적 조사에 의한 생식소 발달과정과 생식주기를 밝혔다. 정소는 정소엽 형태이며, 각각의 정소엽은 여러개의 소낭구조를 가진다. 각 소낭내의 생식세포들은 같은 단계의 발달상태를 보인다. 난소는 원추형의 낭상으로 체강벽에서 연결되는 난소간막에 의해 부착되어 있으며, 내부는 결체성 조직인 다수의 난소박판으로 구성되며, 이곳에서 난원세포가 유래한다. 수컷의 GSI는 1월에 가장 높았으며, 암컷의 GSI는 3월에 가장 높은 값을 보였다. 생식주기는 성장기(6~9월), 성숙기(10~12월), 완숙 및 산란기(1~3월) 그리고 회복 및 휴지기(4~5월)로 나눌 수 있었다. 난모세포의 발달양식은 난군동기발달형에 속하였다.

  • Purpose: This study was carried out to investigate the effects of Guibi Tang(GT) and Placenta Hominis blended Guibi Tang(GTPH) on the postmenopausal osteoporosis. Methods: In order to observe the potential effects of GT and GTPH on the osteoporosis induced by ovariectomy, antioxidative effects of GT and GTPH were measured. Antioxidative activity for the samples was investigated by Rancimat method. Animals were observed for 8 weeks, and vehicle and extracts of prescriptions were administered ad libitum. And we measured the variance of body weight, femoral bone weight, serum level of osteocalcin, calcium, alkaline phosphatase(ALP), estradiol, cholesterol, triglyceride, alanine aminotransferase(ALT) and creatinine. Results: As a result, GTPH showed antioxidative effect, but did not in GT. Body weight increased significantly in 6 weeks after ovariectomy, and the weight of GTPH administered group decreased significantly. GT and GTPH decreased the serum level of cholesterol and triglyceride. Administration of GTPH increased the serum level of ALP when compared with control group. Ovariectomy and GT, GTPH administration had no influence on serum level of ALT and creatinine. Conclusion: According to above results. We suggest that GT and GTPH may be used prevention and curing the postmenopausal osteoporosis.

  • A single bothid specimen (113.9 mm in standard length) was collected by bottom trawl from southern Jejudo Island, Korea. It was easily identified as Kamoharaia megastoma (Kamohara, 1936), based on extremely large mouth. The species is characterized by maxillary extending beyond eyes, three pairs of long curved canines on lower jaw, tip of vomer projecting into mouth cavity, blackish pectoral fin, and blind side without lateral line. We described it as the first record to Korean fish fauna, and proposed the new Korean name, "Keun-ip-dung-geul-neop-chi" for this species.

  • The re-identification of two Korean tonguefishes, Cynoglossus interruptus and Symphurus orientalis, was carried out using eight specimens collected from Korean waters in 2007 and 2013. C. interruptus is characterized by having a single row of scales between rows connected to the supraorbital line and the middle lateral line, 107–113 dorsal fin rays, 86–89 anal fin rays, and 53–55 vertebrae. S. orientalis is characterized by having a 1-2-2-2-2 ID pattern, 97–100 dorsal fin rays, 83–89 anal fin rays, and 52–55 vertebrae. Molecular analysis using mitochondrial DNA Cytochrome Oxidase subunit I sequences showed that specimens of the two species corresponded well to Japanese C. interruptus and Taiwanese S. orientalis, respectively. Therefore, although several reports have raised questions regarding the distribution of C. interruptus and S. orientalis in Korean waters, morphological and molecular data confirm that these two species are indeed distributed in these waters.

  • The present study attempts to (1) identify the critical dimensions that affect job performance of computer programmers and (2) clarify the specific behaviors that are related to each performance dimension, and measure them fairly and accurately. In particular, this study focus on producing a Behaviorally anchored Rating Scales (BARS) with a high level of acceptability by both raters and rates. 422 computer programmers from 8 companies participated in the process of developing the scale, which consisted of typical 5 phases. The results demonstrated that 13 performance dimensions were derived and the final job performance rating scale was made by vertically arraying 5 representative behavior anchors order by their scale value for each of 13 dimensions.

  • Resistance to antibiotics is a problem all over the world, and this problem also is so extended in veterinary fields. Therefore, this study aimed to find out the antibacterial substances from natural medicinal herbs against bovine mastitis pathogens, especially methicillin-resistant Staphylococcus aureus (MRSA). Among seventy two medicinal herbs, Terminaliae chebula extract showed antimicrobial effect against MRSA isolated from mastitis milk in cow and patient in human. However, Terminaliae chebula extract didn't show antibacterial effects on various strains including other contagious and environmental pathogens related with mastitis of dairy cows.

  • For the efficient application of curriculum discretion activity, I developed the program, 'Let's go together', so that curriculum discretion activity can be applied in the classroom. The program consists of several experiences, which are <Man to man paired study>, <the learning materials for Mathematics in our lives>, <the cooperative study in the class> and <the variety experiences about Mathematics>. This study shows the following results: First, T-test about the students' learning attitude and interest in Mathematics, there was dramatic change in students' desire, interest and attitude for mathematics learning. Second, as the role of Baewomi & Dowomi in 'Man to man paired study', Baewomi & Dowomi provided students with confidence of mathematics learning. We were able to ensure this fact from students' essay after the class. Third, teachers found that the number of students who had positive attitude with Self-directed study increased. And students tried to solve mathematical problems by themselves and the time using self-directed learning experience was also increased. This study suggests that there needs more development for learning materials for mathematics in our lives.

  • In this thesis I tried to unearth some Korean Akjang, written and sung by Korean language, not by the form of Chinese verses. In 19th century they used the Korean Akjang at Court banquet cerymony in Chosun Dynasty. I had got four meaningful conclusions through this study, as follow. 1. There are various banquets but they used Korean Akjang only at YaYeon, a sort of night banquet. 2. The Akjangs arranged at YaYeon are called Ak-ka-Samn-jang which means three songs at the banquet. 3. These Akjangs were usually composed of 3 pieces of Gagok, the Korean traditional vocal music, as one. 4. The Kings and princes wrote all the words of these music.
