  • 1. 침파리의 동계사육 결과 평균온도 $23.7^{\circ}C$에서 유충기간 7일, 용기간 9.2일, 전산란기간 14.2일, 성충수명 23.3일이었다. 2. 5월부터 7월까지 사육온도 $25\pm1^{\circ}C$로 고정시켰을 때의 생육기간은 유충기간 8.0일, 용기간 5.3일, 전산란기간 11.7일, 성충수명 30.1일 이었다. 3. 용 개체중량은 5월-7월의 $25\pm1^{\circ}C$에서 13.3mg으로서 현저한 증가를 볼 수 있었다. 4. 전산란 기간중의 성충사망율은 습도 조절(R. H.)에 따라서 큰 차이를 보여주었으며 누대사육을위해서는 $55-65\%$의 R.H.를 유지할 필요가 있을 것으로 본다. 5. 성충의 산란율은 산란 시작후 제8-10일에 제일 높다.

  • In this paper, we discuss design considerations for an n-channel metal-oxide-semiconductor field-effect transistor (MOSFET) with a lateral asymmetric channel (LAC) doping profile. We employed a 0.35 ${\mu}M$ standard complementary MOSFET process for fabrication of the devices. The gates to the LAC doping overlap lengths were 0.5, 1.0, and 1.5 ${\mu}M$. The drain current ($I_{ON}$), transconductance ($g_m$), substrate current ($I_{SUB}$), drain to source leakage current ($I_{OFF}$), and channel-hot-electron (CHE) reliability characteristics were taken into account for optimum device design. The LAC devices with shorter overlap lengths demonstrated improved $I_{ON}$ and $g_m$ characteristics. On the other hand, the LAC devices with longer overlap lengths demonstrated improved CHE degradation and $I_{OFF}$ characteristics.

  • The purpose of this study was to investigate the attitudes of handed-me-down clothing in the Che-ju elementary school children. Measures of attitudes toward handed-me-down clothing consisted of: 1) attitudes of receiver's 2) feeling of receive.'s 3) behaviors 4) possession 5) frequency of wearing handed-me-down clothing. Two aspects of clothing behaviors were slightly modified to assess conformity?individuality, satisfaction in clothing. The sample consisted of 565 students in Che-ju elementary school children, Korea. The data, collected by means of a self-administered questionaire, were analysed by Chi-Square ($X^2$) and Correlation(R). The results indicated that: 1. Handed-me-down clothing was not significantly different between elder brothers (sisters) and child. 2. Most of the children wanted to wear comfort, good style, fit and neat in handed-me-down clothing. 3. Most of the children were satisfied with their handed-me-down clothing and tended not to be aware of the source in clothing. 4. Most of the children had higher interest of individuality and satisfaction in clothing behaviors.

  • The objective of this study was to investigate the effects of the feeding Cordyceps militaris extract on the improvement of the free fatty acid, lipid peroxide, creatinine and enzyme (creatine phosphokinase; CPK, lactate dehydrogenase; LDH, alkaline phosphatase; ALP, lecithin cholesterol acyltransferase; LCAT) activities in the sera of dietary hypercholesterolemic rats (SD strain, male) fed the experimental diets for 5 weeks. Concentrations of free fatty acid, lipid peroxide and CPK, LDH, ALP activities in sera were fairly reduced in the Cordyceps militaris extract administration group (CHE) than in the hypercholesterolemic diet group (CHD). However, no significance was found in the effect of an creatinine concentration among the groups. The LCAT activity in serum was increased in the Cordyceps militaris extract administration (CHE) than in the hypercholesterolemic diet group (CHD). From these results, Cordyceps militaris extracts were effective on the improvement of the lipid components and metabolic enzyme activities in sera of dietary hypercholesterolemic rats.

  • In this paper, we discuss design considerations for an n-channel metal-oxide-semiconductor field-effect transistor (MOSFET) with a lateral asymmetric channel (LAC) doping profile. We employed a $0.35\;{\mu}m$ standard complementary MOSFET process for fabrication of the devices. The gates to the LAC doping overlap lengths were 0.5, 1.0, and $1.5\;{\mu}m$. The drain current ($I_{ON}$), transconductance ($g_m$), substrate current ($i_{SUB}$), drain to source leakage current ($i_{OFF}$), and channel-hot-electron (CHE) reliability characteristics were taken into account for optimum device design. The LAC devices with shorter overlap lengths demonstrated improved $I_{ON}$ and $g_m$ characteristics. On the other hand, the LAC devices with longer overlap lengths demonstrated improved CHE degradation and $I_{OFF}$ characteristics.

  • International major container terminals are trying to expand automation facilities in order to dominate the competition and grow as central harbors. Recently, system design and development were put underway to fully integrate automation systems in container terminals. This is because it can focus on improving the efficiency of the yard operations in container terminals and facilitates integration with other container terminal operation processes. Automation in the container terminal business today is essential to better serve customers and improve profitability. Real-time position and status of container handling equipment (CHE) have been required for more efficient terminal operations and consequently higher productivity. This study examined the real-time location and status of the container terminal automation equipment using DGPS in container terminals, and reviewed the components and functions of the container terminal automation yard equipment systems that developed, applied, and operated the automation systems. In addition, this study compared the existing yard system and the automation yard system and presented application methods. Also, the results revealed that the productivity of the container terminal and the efficiency of the transportation equipment can be further increased when the optimal yard automation transportation equipment system is used to efficiently operate the transportation equipment, which is the core equipment of the container terminal.

  • This research was conducted to identify the following: the home care needs of patients with dementia and the burden on the primary family care giver: to provide basic data required to develop nursing intervention for the care giver: and to suggest recommendations for medical institutions and social services that could reduce the burden on the families of people suffering from dementia. subjects of this research were 53 patients of the two Public Health Centers of Cheju Province who are suffering from dementia and their families. The instrument used in the research was Kuen. Jung Don (1994)' s assessment tool of burden in the primary family care giver who has parents with senile dementia and Yoo. Young Mi(1998)'s assessment tool of home care need. modified by the researcher in the questionnaire by a Likert rating scale. The period of data collection was from February 8. 2000 to March 10. 2000. Collected data was analyzed by SPSS, using mean, standard deviation. ANOVA, t-test and Pearson correlation coefficient. The result of this research was that there was not a significant correlation between the burden on the care giver and the level of dementia, its duration, the patient's ability to perform daily tasks, the period of care giving. and the use of social services, although the lower the patient's ability to perform daily tasks. and the worse the care giver's own health situation, the higher the burden on the primary family care giver. The following suggestions are made based on the results of this research. 1. More than half of the subjects don't use social facilities and services. More publicity and referral efforts are needed about medical institutions. nursing institutions and other facilities that specialize in services for dementia sufferers and their families. 2. Nursing services should include intensive education for the primary care giver in the most important aspects of home care. 3. Further research should be done, and should include data from all parts of Cheju Province.
