An insect faunal survey was carried out to investigate insect community structure along the vegetation community to monitor insect species in forest ecosystem. We performed day and night collections from June to August along three vegetation communities of Is. Nam-hae in 2014: the first stand with Pinus thunbergii, the second P. thunbergii with Quercus serrata and the third P. thunbergii with various Quercus species. In total 2,259 individuals of 532 species, 99 families, 13 orders are identified. Cluster Analyses (CA) showed that all three vegetation communities were relatively similar between vegetation community types. According to indicator species analysis (ISA) result, nine significant indicator species were identified (p < 0.05); five species were found to be affected by the vegetation cluster and four species the month cluster.

N/A Objectives: Mutations in the glucokinase (GCK) gene are considered a possible cause of maturity-onset diabetes of the young. The purpose of this study was to evaluate the contribution of this gene to the development of non insulin dependent diabetes mellitus (NIDDM), gestational diabetes mellitus (GDM) and post-renal transplantation diabetes mellitus (PTDM). Method: Identification of GCK mutation was attempted on 39 NIDDM patients, 2 GDM patients and 58 selected renal allograft recipients with PTDM and 45 normal controls. The exons in the GCK gene were examined by polymerase chain reaction (PCR), followed by analysis of single-stranded DNA conformational polymorphism (SSCP). The abnormal bands were also confirmed by DNA sequencing analysis. The exons of affected family members were also investigated for mutations of the GCK gene. Results: Two of the 58 PTDM patients (3.4%) were found to have CKK mutations. One had the mutation on exon 5 and the other on intron 7. One control subject had the mutation on intmn 9. The mutation of exon 5 was identified as a substitution of CCT (proline) for CTT (leucine) at codon 164, which has not ever reported before. The family members of the PFDM patient with mutation of exon 5 were analyzed by PCR followed by SSCP, and two of them revealed the same mutation. The abnormal band on the SSCP analysis of exon 7 was identified as the insertion of base C/T at the 39th nucleotide in intron 7. Two family members of this patients also had same band on SSCP. The one mutation of 45 normal controls was CT located at the 8th nucleotide in intron 9, which was a common polymorphism. Conclusion: We found GCK mutations in subjects with PTDM and we speculate that these mutations may be one of the contributing cause of PTDM.

권순경,이은방,김미경,박영남 德成女子大學校 藥學硏究所 1998 藥學論文誌 Vol.9 No.1

Allylthio group of the sulfur compounds of garlic oil plays an important role for prevention and treatment of hepatic diseases to be introduced by toxic substances or carbon tetrachloride. Thus allylthio group as a pharmacologically active group was introduced into pyridazine nucleus and a substituent such as halogen or alkoxy was also introduced into the para-posi-tion of allylthio group. Three allylthiopyridazine derivatives were synthesized and their hepatoprotective activities were screened in rat. Under the three compounds (6, 7, 8), 7 and 8 (methoxy-, ethoxy-substituent) are hepatoprotective, but 6 (chloro-substitu-ent) is negative.

최근에 가전 및 군수분야등 여러 분야에서 스위치드 리럭턴스 전동기의 응용에 대한 관심이 커지면서 간단하고 저가이면서 양호한 구동특성을 보이는 속도제어 방식에 관한 연구의 중요성이 증대되고 있다. 본 논문에서는 스위치드 리럭턴스 전동기의 속도제어 방식에서 제어 가능한 변수로서 점호각과 소호각, 소정의 전류슈준을 설정하여 이 세가지 제어변수를 고려한 전압제어 및 전류제어 알고리즘을 설계하였다. 특히 스위치드 리럭턴스 전동기 및 인버터 구동회로를 포함하는 전체시스템의 특성을 고려한 전압제어 및 전류제어 알고리즘을 강구하였으며 이와 함께 원칩 마이크로프로세서인 80C196KC를 이용한 전압제어 및 전류제어를 구현하였다. 80C196KC는 고속입출력기능, PWM 기능, A/D컨버터기능 등을 내장하는 16비트 원칩 마이크로프로세서로서 본 연구에서는 이러한 기능들을 적절히 활용하는 전압제어 및 전류제어 알고리즘을 구성하고 상호 비교를 수행하였다. 본 연구에서 설계된 전압제어 및 전류제어 시스템은 실험을 통하여 운전특성 및 성능을 검증하였으며 본 연구를 통하여 80C196KC가 가지는 기능들은 불연속여자특성을 가지는 스위치드 리럭턴스 전동기의 전압제어 및 전류제어 구성에 매우 부합됨을 확인하였다. 본 연구에서 구성된 속도제어 시스템은 간단하고 저가이면서 양호한 구동특성을 보이는 속도제어 시스템에 활용될 것으로 기대된다. The switched reluctance motor is comparable to the inverter driven induction motor. Recently a switched reluctance motor is highly considered for the applications to home appliances and defence industry. Simultaneously a low cost controller with high performances becomes more significant for a switched reluctance motor drive. This paper investigates voltage and current controls of switched reluctance motor which are considering turn-on angle, turn-off angle and current level as controlled variables. One-chip microprocessor 80C196KC, an embedded microcontroller, is well applied to voltage and current controls of switched reluctance motor because a switched reluctance motor is excited by the excitiation modes of pulse type. Voltage and current control algorithms are implemented by utilizing several functions of 80C196KC. The proposed drive system is verified through the experiments, and may be utilized as a drive system with a low-cost and high-performance controller.

권영경,이영남 동아시아식생활학회 2004 동아시아식생활학회지 Vol.14 No.6

This study was aimed for examining the changes of eating habit and behavior according to the degree of stress of elementary school students. It was tried to identify their daily stress levels and their relevances with the changes of their eating habits and behaviosr. The subjects were 500 students from fifth and sixth grades in three elementary schools in Seoul. The students surveyed showed to get moderately stressed in general. The stress level of girls were higher than that of boys(p<0.001) in the individual area. The breakfast ratio of the low stressed group(LS) marked higher(p<0.001) than those of both the middle-(MS) and highly-stressed group(HS). In other words, the LS group had regular breakfast. The main reason why they were skipping breakfast was lack of time. The amount of a meal in the HS group was noticeably bigger than the other two groups(p<0.05) and the amount of salt and spices used was higher(p<0.01).The amount of food taken when they got stressed was increased remarkably higher in the HS group and students in that group had snacks as the way of relieving the stress. The HS group displayed higher ratio of the unbalanced diet habit. There were noticeable differences in the eating habit and behavior, i.e. the amount of meals, of salt used and whether eating breakfast or not, in accordance of the levels of stress.

A bacterium producing Cyclodextrin Glucanotransferase (CGTase) and Cyclodextrinase (CDase) was isolated from soil, and named as Bacillus stearothermophilus KJ16 . The growth of the isolated strain occurred in two steps, and syntheses of CGTase and CDase were dependent on the growth cycle of the cell. CGTase was constitutively synthesized during the 1st growing phase. while CDase was synthesized inducibly during the 2nd growing phase. When the medium pH was controlled at 7.0, the maximun enzyme activities of CGTase and CDase were increased by 12-fold (1300 mU/ml) and 2-fold (225 mU/ml), respectively, compared with the pH-uncontrolled batch culture. The CGTase of the isolate converted soluble starch to CDs with the ratio of α-CD:β-CD:γ-CD=42:46:12 at 55℃. The optimal pH and temperature of CGTase were 6.0 and 60℃,respectively and the optimal pH and temperature of CDase were 6.0 and 55℃. The molecular weights of the purified CGTase and CDase were estimated to be 65,000 and 68,000 dalton, respectively, Among serveral substrates, γ-CD was most rapidly hydrolyzed by the purified CDase.

The purpose of this study is to estimate the National Health Insurance budget needed for the Korean elderly's denture service coverage. For more exact estimating the budget, denture need and demand were calculated by using 2000 National Oral Health Survey data. The results were summarized as follows ; 1. Over 65 years old, full denture and partial denture need per arch were each 8.5% and 16.8%. And over 70 years old, those were each 11.3% and 17.8%. 2. Over 65 years old, full denture and partial denture demand per arch were each 22.8% and 21.2%. And over 70 years old, those were each 27.%% and 21.1%. 3. Based on the denture need, the health insurance budget needed in the first operative year was about 955.4 billion won, over 65 years old and about 644.2 billion won, over 70 years old. 4. Based on the denture demand(wear), the health insurance budget needed in the first operative year was about 207.5 billion won, over 65 years old and was about 151.6 billion won, over 70 years old. If health insurance policy of elderly's denture service coverage is performed, actual denture wear rate is going to increase, and the budget needed is also increasing. Because current National Health Insurance budget status is poor, it is difficult to execute health insurance coverage for elderly's denture service. Therefore we suggest that health insurance coverage for preventive service is to be considered in order to reducing denture need in the long term view.
