Recently, we have used internal fixation with titanium miniplate which introduced by Champy in 1976 in facial bone fractures. In cases of mandibular fractures, particulary mandibular angle fractures, we usually underwent the open reduction extraorally. But extraoral approaches may leave scars and put the facial nerve at greater risk. So, we had undergone the intraoral approaches in 31 patients of mandibular angle fractures (male : 29, female : 2)> These patients visited in Wonkwang university hospital from October 1991 to June 1993. We got easy operation time as average 20 minutes than extraoral approach. And reduced the postoperative nerve injury(14.2%), but postoperative infection is 6.1% nearly as same as extraoral approach. TMJ problems after intraoral open reduction was similar to extraoral approaches.

3원교잡종(LY×D) 돼지를 이용하여, 60일 동안 미생물제제 K를 3% 급여한 A 처리구와 O를 3% 급여한 B 처리구 및 가고시마흑돼지에게 10% 고구마 사일리지를 급여한 C 처리구로 각 처리구별로 30두씩 공시하여 사양 시험 후 돈육의 지방산, 아미노산 조성 및 관능적 특성에 미치는 효과를 분석하였다. 가열육의 관능검사에서는 B 처리구가 다른 처리구들에 비하여 유의적으로 높은 값을 보였다(p<0.05). 처리구 간에 지방산 조성 변화를 보면 palmitic과 palmitoleic acid 함량은 C 처리구가 다른 처리구들에 비하여 유의적으로 높았다(p<0.05). Aspartic, threonine, serine, glutamic, isoleucine과 phenyl alanine 함량은 C 처리구가 다른 처리구들에 비하여 유의적으로 높았다(p<0.05). Proline, alanine, cystine, valine, methionine, leucine과 histidine 함량은 B 처리구가 다른 두 처리구들에 비하여 유의적으로 낮은 아미노산 함량을 보였다(p<0.05). A total of 90 pigs were used to investigate the effect of feeding microbes and sweet potato silage on physico-chemical characteristics of pork loin. About 60 kg pigs were randomly alloted into one of three experimental diet groups (A: Supplemented with 3% K microbe; B: Supplemented with 3% O microbe; C: Supplemented with 10% sweet potato silage). Pigs were slaughtered at approximately 110 kg live weight and fatty acid, amino acid and sensory characteristics were measured in pork loin. In cooked meat, sensory evaluation was significantly higher in B compared to other treatments (p<0.05). The palmitic and palmitoleic acid content of C treatment were significantly higher than those of other treatments (p<0.05). In amino acid composition, aspartic acid, threonine, serine, glutamic acid, isoleucine and phenyl alanine level were significantly higher in C treatment compared to other treatments (p<0.05).

Berkshire를 이용하여 70일간 산삼 배양액 급여 시 육의 이화학적 특성에 미치는 영향은 다음과 같다. 산삼 배양액의 급여에 의해 육의 수분, 조단백, 조지방, 회분, pH, 가열감량, 콜레스테롤 함량, 육색, 조직감의 응집성과 검성, 포화지방산 및 불포화지방산의 비율은 차이를 보이지 않았다. 보수력, 지방색 L^(*)값, 지방산 중 linoleic acid(18:2), arachidonic acid(20:4), 필수지방산의 함량, 아미노산 중 threonine, glutamic acid, valine, isoleucine, leucine, histidine, lysine 및 총아미노산 함량은 산삼 배양액의 급여에 의해 감소하였다. 전단가, 조직감의 표면경도, 경도, 씹힘성, 지방산 중 stearic acid(18:0), oleic acid(18:1) 함량, 아미노산 중 serine, glycine, cystine, methionine, tyrosine 및 phenylalanine의 함량은 산삼 배양액의 급여에 의해 증가하였다. 본 연구결과를 종합하면 산삼 배양액의 급여는 돈육의 경도를 증가시키는 효과 외에 뚜렷한 이화학적인 차이를 나타내지 않았다. 이러한 이유는 급여된 산삼 배양액 내에 함유된 생리활성 물질의 함량이 낮고, 급여수준이 낮은 결과로 사료되어진다. A total of 60 pigs (Berkshire) were used to investigate the effect of dietary artificial culture medium of wild ginsengs (CMG) on physico-chemical characteristics of pork. About 60 kg pigs were randomly alloted into one of two experimental diet groups (C:commercial diet feed; T:commercial diet + 1 L CMG per day for 70days). Pigs were slaughtered at approximately 110 kg live weight, and chemical composition and physico-chemical characteristics were measured in pork loin. Moisture, crude protein, crude fat and ash were not significantly different by dietary artificial culture medium of wild ginsengs. Water-holding capacity was decreased by dietary artificial culture medium of wild ginsengs, while shear force was increased. However, pH, cooking loss and cholesterol contents were not significantly different between two different treatments. In color, L^(*) of fat was decreased by dietary artificial culture medium of wild ginsengs. Brittleness, hardness and chewiness were increased in dietary artificial culture medium of wild ginsengs group. In fatty acid, stearic acid (18:0) and oleic acid (18:1) were higher in dietary artificial culture medium of wild ginsengs group, whereas linoleic acid (18:2) and arachidonic acid (20:4) were higher in control group. In amino acid, serine, glycine, cystine, methionine, tyrosine and phenylalanine were higher in dietary artificial culture medium of wild ginsengs group, whereas threonine, glutamic acid, valine, isoleucine, leucine, histidine and lysine were higher in control group.

Objectives : This study was designed to assess the relationship between alcohol use and stress. Methods : The study subjects were 1,261 people who drink among the 2,565 people who lived in Gangneung. We investigated the sociodemographic characteristics, Short Form-12 (SF-12), Global Assessment of Recent Stress (GARS) and Alcohol Use Disorder Identification Test (AUDIT). Results : In Problem drinking group the GARS was significantly positively associated with the AUDIT (p=0.02). In Social drinking group sex (p<0.001) and age (p=0.02) is significantly associated with the AUDIT. Conclusion : This study showed the significantly positively association between stress and alcohol use. We think that the intervention and active management of the stress can prevent the alcohol problem.

e-로지스틱스에서 효율적인 차량관제를 위한 질의 처리기 구현

김동호,김진석,류근호 한국지리정보학회 2004 한국지리정보학회지 Vol.7 No.3

최근 부각되고 있는 텔레매틱스와 위치기반서비스의 효율적인 구축을 위해서는 실시간으로 수집되는 방대한 분량의 위치 데이터의 저장, 질의, 프리젠테이션 등을 포함하는 이동체 기술이 필요하다. 특히 물류분야에서 이동중인 차량의 데이터에 대한 효과적인 검색과 분석을 위해서는 응용별 특화된 형태의 데이터를 획득할 수 있는 질의구문이 요구되며, 전통적인 데이터베이스 질의어와 비교할 때 그 구조는 복잡한 양상을 보인다. 이에 대한 효과적인 대안으로는 SQL과 같은 표준화 데이터베이스 언어를 통한 접근을 고려할 수 있다. 따라서 이 논문에서는 e-로지스틱스 기반의 차량관제에서 요구하는 질의에 대하여 SQL를 확장한 이동체 질의어(MOQL)를 제안하고, 이를 효과적으로 처리하기 위한 질의처리기를 설계 및 구현한다. Telematics and LBS is one of rapidly emerged technology domains. In order to efficiently construct them, moving object technology which manages huge volume of real-time location data is required. Especially, the query which obtains special sorts of information closely related to the detailed applications is required in order to effectively retrieve and analyze the location data for moving object in logistics domain. It has also complex query structure comparing to the conventional database query. The approach using the standard database query language, like SQL, can be considered as an effective alternative choice. In this paper, we not only propose a new query language, entitled as MOQL based on SQL, for the query processing of the vehicle monitoring and control in e-Logistics but also design and implement the query processor.

Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherapy seems a logical choice for cancer chemotherapy. In this study, Mitomycin C (MMC)-activated charcoal (CH)-alginate (ALG) beads were prepared by the mixtures of CH particles adsorbed with MMC as an anti-cancer drug and aqueous alginate solution. The alginate is recognized as biodegradable, nontoxic, and biocompatible. The release of MMC from the beads in 0.1 M Tris buffer was stable and continuous until about 1 week. The MMC-CH-ALG beads can be applied in the peritoneal cavity for intraperitoneal chemotherapy since they provide a good adhesiveness on the tissue and controlled release pattern of the drugs.

완전뇌허혈후 재관류시에 국소뇌혈류, 체성감각유발전위 및 신경학적 회복에 대한 Mannitol과 Thiopental의 효과

박춘근,이상원,박영섭,최승진,허필우,정동섭,강준기,최창락 대한신경외과학회 1996 Journal of Korean neurosurgical society Vol.25 No.2

The cardiopulmonary bypass or cerebral circulation arrest is often used in the treatment of complex aneurysm or of arteriovenous malformation to decrease the risk of intraoperative aneurysm rupture. Although experimental studies have suggested that some drugs may protect the brain from ischemic injury, there are limitations in maintaining cerebral perfusion arrest without incurring neurologic deficits due to the initiation of detrimental processes including excitotoxic neuronal injury, activation of phospholipases, influx of calcium, and generation of damaging free radicals. The purpose of this study is to determine wheter mannitol or thiopental has any favorable effects on the recovery of neurologic deficits and on the regional cerebral blood flow(rCBF), somatosensory evoked potential(SEP) and electroencephalogram(EEG) in cats which underwent 15 minutes-complete global ishcemia-reperfusion. The complete global ischemia was produced in 38 cats by temporary intrathoracic occlusion of the innominate artery and the subclavian artery following ligation of bilateral mammary arteries and simultaneous induction of hypotension. The cats were allocated randomly to one of 4 treatment groups : (1) control group, 8 cats received equal volume of saline solution : (2) thiopental group, 10 cats received 45㎎/㎏ thiopental intravenously, (3) mannitol group, 10 cats received 2g/㎏ mannitol intravenously, (4) combined mannitol and thiopental group, 10 cats received equal dose of mannitol and thiopental intravenously. The drugs were administrated in a equally divided dosage before and after the ischemic episode. The results were as follos : 1) Eight animals which received saline showed the severe postischemic hypoperfusion and poor recovery of SEP and EEG, and 6 of them died within 6 hours after the ischemia. 2) Ten thiopental-treated animals also showed the severe postischemic hypoperfusion and poor recovery of SEP and EEG, and 6 of them died within 6 hours the ischemia. 3) Both mannitol-and combined treated groups showed early recovery of EEG, good recovery of SEP and EEG without the severe postischemic hypoperfusion, and 7 of 10 mannitol-treated animals and 8 of 10 combined treated animals were significantly recovered in all parameters. There were not significant differences in all parameters between the mannitol-and combined treated groups. 4) Thirty-four of 38 animals involved in this 15 minutes-ischemia resulted in the severe neurologic deficits inspite of treatment with mannitol, thiopental or both of them. These results suggest that, in cats, mannitol treatment is effective but not thiopental in preventing severe neurologic injury following complete global ischemia and the duration of complete ischemia should be far less than 15 minutes.

朴成振,尹東根,朴久富 진주산업대학교 1985 論文集 Vol.23 No.-

後期飼料를 3주령부터 조기에 급여한 9주령 Hubbad鷄肉의 3부위 근육을 공시육으로 하여 4℃에서 저장하면서 경시적(도살직후 저장후 2일 4일 7일)으로 지질의 함량을 추출하고 지방산의 조성을 GLC로 분석한 결과 다음과 같은 결과를 얻었다. 1. 지질함량은 도살직후 대퇴부위가 2.67%로 가장 높고 흉심부가 2.38%, 근위 1.28% 가장 낮았으며, 저장기간에 따른 지질함량의 변화는 3부위 모두 저장기간의 경과에 따라 지질함량이 감소하였다. 2. GLC로 분석한 지방산은 3부위 모두 myristic acid(14:0)로 부터 arachidonic acid(20:4)까지 10種을 분리 동정하였다. 3. 함량이 제일 높은 지방산은 세부위 모두 불포화 지방산인 Oleic acid로 40.7~45.5%였고 다음 Palmitic acid로 20.5~27.9%였으며 linoleic acid는 6.9~18.3%로 타육류에 비해 필수지방산인 linoleic acid의 함량이 높았다. 4. 3部位 모두 저장시간이 경과함에 따라 포화지방산의 함량이 증가되고 불포화지방산의 함량은 상대적으로 감소되었다. The meat cut 3 parts of leg, breast and gizzard of broiler-Hubbard at 9 weeks fed early finisher diet from 3 weeks were stored at 4℃ for four levels, immediately after slaughtering, 2 days, 4 days and 7 days after storing in order to extract lipid contents and fatty acid compositions was analyzed by the GLC method. The results obtained in this experiment were summarized as follows: 1. Lipid contents were the highest with 2.67% in the leg immediately after slaughtering and the lowest, with 1.28% in the gizzard. Fatty acid compositions were decreased in all the three parts as the storage time passed. 2. Ten fatty acids from myristic acid(14:0) to arachidonic acid(20:4) in all the there parts were identified by GLC. 3. The highest fatty acid was oleic acid with 40.7 to 45.5% and the next, palmitic acid with 20.5 to 27.9%. Linoleic acid was higher with 6.9 to 18.3% in broiler-Hubbard then in the other broiler. 4. As the storage time passed, saturation fatty acid increased and unsaturation fatty acid decreased relatively.

Objective : To compare two different methods of rigid fixation in postoperative stability after mandibular setback, Material and Methods : 28 patients with Class III malocclusion were treated by bilateral sagittal split ramus osteotomy(BSSRO) and mandibular setback were selected for this study. Group A(n=14) had the bone segments fixed with monocortical miniplate on the lateral side of the mandibular body and Group B(n=14) had three noncompressive bicortical screw inserted at the genial area through a transcutaneous approach. Cephalograms were taken preoperatively, postoperatively within 1 weeks and at a follow-up period (mean 8.9 months after surgery) and the amount of setback and postoperative change were measured. Results : Postoperative relapse between two groups was minimal in setback of the mandible. Statistical analysis showed no significant difference in postoperative relapse. Conclusion : This study suggests that both methods of skeletal fixation investigated give comparable postoperative stability and their use in mandibular setback appears to be a fairly stable clinical procedure.
