The main purpose of this study is to analyze the impact of parenting behavior on school violence behavior of students of specialized high schools with experience in school violence, the impact of self-esteem on school violence behavior, the impact of parenting attitude on self-esteem, and the perception of school violence on students. A total of 122 students were subject to the study, with boys and girls from specialized high schools (101 men and 21 women) with experience in committing school violence. For measuring instruments, parents' adoptive attitudes and background information are based on Barber (1997), Kim Hae-young (2000) reconstructed and recreated based on Barber (1995), and Rosenberg (1965V s self-esteem measures were used by Lee Chun―jin and Won Ho―taek (1995),while Kim Sun-joon (1995) developed a Korean version of a school violence experience. The results of the analysis are as follows. First,after analyzing the impact of parental attitudes on school violence, it was found that the higher the self-esteem, the lower the school violence. Second, after analyzing the impact of parental attitudes on self-esteem, the higher the level of confidence among parents' attitudes, the higher the level of self-esteem. Third,after analyzing the impact of self-esteem on school violence, the results showed that self-esteem does not affect school violence. Fourth, after analyzing the perception of school violence by students with experience of committing school violence in specialized high schools,the school violence was most said to be very serious, in the order of normal,unresponsive and serious. As the leading solver of school violence, the parties responded the most,followed by schools,non-response, police and friends.

Fresh-cut 채소 제품이 소비자에 의해 선택되어 소비되려면 이의 친환경적 원료생산과 가공, 포장, 서빙에 이르는 전 과정에서 체계적인 품질관리가 이루어져야 하며 갈변제어, 연화제어 및 미생물적 제어 등 관련 기술의 연구개발이 요구된다. 본 연구에서는 시중 유통 · 판매되고 있는 fresh-cut 채소제품의 품질을 비교평가하기 위해 현재 유통되고 있는 9개사 제품을 선정하였으며, 관능검사를 포함하여 vitamin C, 무기질, 중금속 함량, 잔류농약 및 미생물오염 정도를 조사하였다. 관능평가에서는 갈변 등 품질변화로 인해 전반적인 기호도가 그다지 높지 않았다. 채소류에서 중요 영양성분인 vitamin C 함량은 9개사 모든 제품의 주재료인 양상추에서 거의 검출되지 않았고 다른 채소류의 vatimin C 함량 역시 식품성분표보다 소량이었다. 무기질 함량 역시 극히 소량이었는데, 이는 박피, 절단 등의 최소 가공 공정을 거치면서 파괴되기 쉬운 vitamin C와 무기질이 대부분 손실되었기 때문으로 사료된다. 안전성측면에서 평가한 잔류 중금속 함량의 경우 몇 개의 제품에서 구리와 납이 소량 검출되었으며 잔류농약은 검출되지 않았다. Most fresh-cut agri-food products are less stable than the unprocessed materials from which they are made. The objective of this study was the development of a quality control system for fresh-cut agri-food products. In this study, the vitamin C, mineral, residual heavy metal contents and pesticides of various fresh-cut agri-food products were analysed. Through the sensory evaluation, the reason for the lower than expected overall acceptability in most products is that cut products are likely to cause browning and easily lose their freshness. Therefore, the postharvest technology that can maintain the quality, freshness and appearance must be supplied. Vitamin C contents did not exist in all salad products of the selected 9 companies, although vitamin C and mineral contents that are main nutrients that can be supplied mainly in salads. The results showed that vitamin C and mineral contents were very small and extremely small in other vegetables compared with the standard of a food ingredient, It is possible that vitamin C and most minerals are easily destroyed were lost through the minimal process like peeling and cutting. In safety side, the remaining heavy metal contents of fresh-cut agri-food were investigated and the results showed that copper and lead existed in some products because cadmium in agricultural produce is only controlled by the minimum standard of heavy metal contents in Korea. No residual pesticides were detected in all products.

Laminated composites are in the form of laminates consisting of multiple laminae oriented in the design directions and bonded together in a structural unit. The virtually limitless combinations of ply orientations, ply thickness and ply stacking sequences offered by laminated constructions considerably enhance the design flexibility inherent in composite structures. And it is known that genetic algorithms has an excellent ability in the area of combinatorial optimization problem. Therefore, the present paper deals with the stiffness and weight optimization of laminated composites under multiaxial loading on the basis of genetic algorithms.

A biosurfactant-producing microorganism was isolated from activated sludge by enrichment culture when grown on a minimal salt medium containing n-hexadecane as a sole carbon source. This microorganism was identified as Pseudomonas sp. and it was named Pseudomonas sp. EL-G527. It's optimal culture condition is 2% n-hexadecane, 0.2% NH_4NO_3, 0.3% KH_2PO_4, 0.3% K_2HPO_4, 0.02% MgSO_4·7H_2O, 0.0025% CaCl_2·6H_2O, 0.0015% FeSO_4·7H_2O in 1ℓ distilled water and initial pH 7.0. Cultivation was initiated with a 2% inoculum obtained from starter cultures grown in 30 ㎖ of the same medium in 250 ㎖ flask. They were cultivated at 30 ℃ in reciprocal shaking incubator and the highest biosurfactant production was observed after 4 days.

Background : Previous data have been reported that subtype B is prevalent in South Korea, but neither the extent nor the proportion of subtypes could be evaluated. This study was designed to analyze the distribution of HIV-1 subtypes, temporal instructions and transmission dynamics between epidemiological groups. Methods : 1,280 Koreans had been diagnosed as HIV seropositive during the period 1985 to 2000. Among them, 134 individuals were selected for this molecular epidemiological study. 134 DNAs were isolated from uncultured or cultured peripheral blood mononuclear cells. V3-V5 (0.7 kb) fragment of HIV-1 env gene was amplified by nested polymerase chain reaction and was sequenced. Results : HIV-1 isolates from thirty-seven homosexuals were all subtype B (100%). On the other hand, 66 isolates from 94 heterosexuals were subtype B (70%) and 28 were non B subtypes (30% : 13 A, 4 C, 2 D, 8 E , 1 G). Only subtype B strains were isolated from 73 males who were infected with HIV inside Korea while 16 B and 20 non B subtype strains were isolated from 36 males who were HIV infected outside of Korea. However, B and non B strains were isolated half and half from females who were infected inside Korea except one. Conclusion : The HIV-1 subtype B strains are prevalent in Korea from the early HIV infection until present in both homo and heterosexuals. Non B strains have been transmitted from men who were infected outside Korea to their spouses and casual partners. So, we need further study to monitor subtype B and non B HIV transmission in epidemiological groups of Korea, (Korean J Infect Dis 33:311∼318, 2001)

Columella 缺損例의 成形外科的 治療 : 1例報告

임풍,조문제,빈주원,함기선 大韓成形外科學會 1976 Archives of Plastic Surgery Vol.3 No.1

Columella defect is a noticable deformity which is seen following its loss secondary to injures, diseases, or surgical excisions. The reconstruction of the defect can be achieved by one of the following four methods as advocated by Converse in 1964, i.e. 1) the cervical tubes, 2) the forehead flaps, 3) the nasolabial flaps, and 4) the composite grafts. There is tendency for most surgeons to prefer the nasolabial flap method because of the lesser extend of resulting scar and deformities. Authors obtained a good result in correcting a columella defect from a chronic inflammatory disease in 27 years old woman. Vomerian and nasal tip flaps were employed to make a new columella and the resulting inner raw surface was covered with buccal mucous membrane of the upper lip. The pedicle of the mucosal flap was detached on 10th postoperative day.

Laparoscopic sleeve gastrectomy can reduce morbidity and mortality in patients with morbid obesity, but it can cause complications such as a gastrointestinal leak. A 30-year-old morbidly obese female who had type 2 diabetes mellitus and hypertension with estimated body mass index of 40.2 kg/m2 was admitted. Laparoscopic sleeve gastrectomy was performed. On postoperative day 19, a leak was suspicious on physical examination and radiologic findings. Conservative management was performed, but the patient was hemodynamically unstable and imminently septic. After laparoscopic drainage procedure, esophagogastroduodenoscopy was performed and revealed the fistula opening at staple line just below gastroesophageal junction. Fibrin tissue adhesive was injected around the fistula and the esophageal covered stent was inserted to cover the leak. At 14th days after stent insertion, the barium study confirmed no more leak. In this case, we experienced that the esophageal stent insertion with fibrin tissue adhesive injection may reduce recovery time of the fistula developed after laparoscopic sleeve gastrectomy

Minimal inhibitory concentrations of total 148 strains isolated from blood culture at Seoul National University Hospital were determined by Vitek System. 90% MIC of gram-negative bacteria against amikacin was 2-16㎍/㎖, and those against beta-lactams was > 16㎍/㎖ in general, Except Salmonella spp,. 90% MIC against chloramphenicol and tetracycline was >8㎍/㎖. Range of 90% MIC against vancomycin was ≤.5-4㎍/㎖ in case of garm-positive bacteria, except Enterococcus spp. which showed 90% MIC as >16㎍/㎖. Against ampicillin, 90% MIC of Staphylococcus spp. was >16㎍/㎖, but those of Streptococcus spp. was ≤.25-2㎍/㎖. Streptococcus viridans group showed 90%MIC against penicillin as ≤.03㎍/㎖. Susceptibility of gram-negative bacteria was generally 98% against amikacin, and those of gram-positive bacteria was 80% against vancomycin. 34% of Staphylococcus spp. was resistant of oxacillin. These results may be useful for the primary selection and the dosage determination of antibiotics in the treatment of patients with bacteremia.
