2000년대에 들어와 현재 한국의 과학기술혁신정책은 정책 영역이 확장되고 위상이 높아지는 등 새로운 모습을 보여주고 있다. 그리고 이제는 외국 기술의 모방이 아니라 새로운 발전 궤적을 창출하는 창조형 전략을 명시적으로 주장하고 있다. 또한 과학기술계중심의 부문 정책, 경제성장 중심의 정책을 뛰어 넘어 사회정책과도 연계를 형성하는 통합적 정책의 양상들이 전개되고 있다. 그러나 이런 정책들은 핵심적인 정책 패러다임으로 발전하고 있지는 않다. 과거 추격시대의 모방형 과학기술중심 경제중심의 관행들이 여전히 작동하고 있어 새로운 경향들이 쉽게 자리 잡을 수 없기 때문이다. 따라서 2000년대 과학기술혁신정책은 '추격과 성장' 이라는 과거와 '창조와 통합'이라는 미래가 서로 공존하는 이행기적 양상을 보여주고 있다.

A survey on the fishing gear for octopus drift-line fishing was done in Gangwon-do, Sacheon, Gyeongnam and Hokkaido, Japan, while a survey on the environments of fishing grounds used data from January to August from the Korea east coast farming forecast system of Donghae Fisheries Research and Development Institute. The present situation of fishing was examined with boats engaging in drift-line fishing from March to August in the coastal waters along Gangneung. The fishing tackle for octopus drift-line fishing was made manually, and the size, shape, and weight of the hook and number of shooting used vary according to the fishing time and region. Lead is used as the material for sinkers. As bait, pork fat with skin is mostly used in Gangwon-do. The temperature of the bottom water layer in the coastal fishing ground of Gangneung from April to June ranges from $3.2-12.4^{\circ}C$, which is the optimal temperature for octopuses. During July and August, the temperature ranges from $5.0-20.6^{\circ}C$. The maximum difference between day and night temperatures reached up to $9.2^{\circ}C$. Salinity is generally stable at $33.2-35.324.6%_{\circ}$, which does not affect the inhabitation of octopuses. The octopus catch reached its peak from May to July, while most octopuses weighed less than 1 kg (76.7%). The results show that it is effective to carry out octopus drift-line fishing up to a depth of 40 meters; and that the maximum number of octopuses per line is obtained with an operation time of six hours.

These experiments were designed to study the influence of protein undernutrition during lactation period(3 wks) or after-weaning period(8 wks) on growth of organs, and on brain and liver composition of the experimental rats. The following experimental groups were studied. Group No. Rats Lactation(3 wks) (Diet of mother rat) After-weaning period(8wks) Rehabilitation Period(17wks) I 8 25% Casein diet 25% Casein diet 25% Casein diet II 8 12% Casein diet 25% Casein diet 25% Casein diet III 8 25% Casein diet 5% Casein diet 25% Casein diet IV 8 12% Casein diet 5% Casein diet 25% Casein diet After the perriod of rehabilitation(17 wks) with 25% casein diet, the following results were obtained. 1. Most of the organs except the spleen could not catch up with the normal group in their weights for the group of protein undernutrition during lactation(3 wks), even after 17 weeks of rehabilitation. For the group of protein undernutrition during after-weaning period(8 wks) brain, lung, heart, spleen and pancreas could catch up with the normal group after rehabilitation. According to this result it is assumed that the growth of brain, lung, heart and pancreas might be developed mostly during lactation and that the growth of liver and kidney might be developed after-weaning period continuously. 2. For the groups of protein underuntrition during lactation period or after-weaning period the amounts of total lipid, cholesterol and phospholipid of brain were lower than those of normal group. Especially, cholesterol level was significantly lower than normal group. And there was also a significant difference in the phospholipid level of the after-weaning(8 wks) deprivation group. 3. The groups of protein undernutrition during lactation or after-weaning period(8 wks) showed lower level of liver nitrogen and higher level of liver fat. Especially, protein undernutriton during lactation gave a greater influence on the lever of liver fat.

Objectives : We aimed to explore weekend catch-up sleep (CUS) by age and to find out the association between CUS and depression by the age group and weekday sleep duration (SD). Methods : Using data from the 2016-2018 Korean National Health and Nutrition Examination Survey, the CUS by age of 16,174 subjects was investigated, and the depression data of 11,088 subjects were analyzed. CUS was calculated as the weekend sleep duration minus weekday sleep duration (SD). The mean of CUS and weekday SD in depression group and non-depression group was compared by early, middle, and late adulthood groups, and logistic regression analysis was performed to investigate the effect of CUS on the depression by age group when weekday SD was insufficient. Results : The CUS tended to decrease continuously with age, the mean of CUS in the late adult group was the shortest. However, the average SD, adjusted for weekend CUS, was the shortest in the middle adulthood group. Overall, the sleep durations were shorter in the depression group than in the non-depression group, but the CUS difference between the two groups was significantly only in the middle adulthood. The risk of depression was significantly higher when weekend CUS was less than 1hour with a short weekday SD of less than 6hours (OR 2.44, 95% CI: 1.78-3.35), and this finding was significant in all adult groups. Conclusions : The findings of this study suggest that short weekday SD and inadequate weekend CUS are associated with depression and that CUS is an option to compensate for sleep deprivation and prevent depression.

Background and Objectives: Dizzy patients with abnormal otolith function tests, despite a normal caloric response, are defined as having specific (isolated) otolith organ dysfunction. This study was performed to compare the differences in clinical presentation between isolated otolith dysfunction (iOD) patients with lab- and Sx-based iOD group and lab-based iOD symptoms. Subjects and Methods: The medical records of 23 iOD patients with normal caloric response but abnormal cervical vestibular evoked myogenic potential (VEMP), ocular VEMP, or subjective visual vertical were reviewed. Non-spinning vertigo was considered as otolith-related symptoms. The patients' age, onset of dizziness, Numeric Rating Scale on the severity of dizziness, and concomitant vestibular disorders were analyzed. Results: Patients in the lab-based iOD group were significantly older than those in the lab- and Sx-based iOD group. Known vestibular disorders were significantly more common in the lab-based iOD group (83.3%) compared to the lab- and Sx-based iOD group (18.2%). Despite the normal caloric response, catch-up saccade was found in the video head impulse test in more than half (54.5%) of the lab-based iOD group patients. There was no catch-up saccade in the lab- and Sx-based iOD group. There were no significant differences in gender ratio, frequency of dizziness attacks, and duration of illness. Conclusions: We propose new definitions of definite iOD (lab- and Sx-based iOD) and probable iOD (lab- or Sx-based iOD). These new definitions may help researchers to identify patients who are more likely to have true iOD, and facilitate comparisons of results between different studies.

The sailors on seagoing ships experience much difficulty in communicating with their families, friends or associates ashore due to communication cost or technical difficulties so that they are sometimes unable to adapt to the rapid social changes promptly. This is mainly the result of an insufficient Information and Communication Technology (ICT)-environment on their ships. To surmount such a problem, an electronic shipboard voting system that guarantees the publicness and absolute secrecy in voting process has been proposed in this paper. The system not only helps crews to catch up with up-to-date news and provides them a feeling that they are being connected to the everyday lives of the outside world, but also allows them to cast their votes based on the newly acquired information (e.g., current political or economic situations in their respective regions and etc.).

Parks in Kwang Ju ar determined by the development of a housing project under the regulations of land development rather than the planning approach of park provision. This study tries to identify who is the provider of parks, to estimate the size of urban parks per person in the area of the housing project, to look at the spatial allocation patterns of park provision and to identify the character profiles of users and the social profile of an ares(Dong). This research has produced the following major conclusions : 1. The city government should set up a master plan of park provision to control park delivery system to avoid maldistribution. 2. A positive discrimination policy should be introduced to disadvantaged areas in terms of park provision. 3. The null hypothesis - there is no relationship between distance and park Use - is rejected by the correlation rate of 0.4984. 4. The ratio of parks per a person ; 10.43㎡/person in 1990 has decreased to 10.41㎡ /person in 1994. This means that the increase of parks in terms of quantity could not catch up the increase of population.

Currently national High Voltage Gas Insulated Switchgear (GIS) operating mechanism is made up of spring operating mechanism or hydraulic operating mechanism. On the contrary, advanced technology trend in foreign countries replace current mechanical mechanism with electrical motor-drive mechanism that leads to participate GIS bid and increase sales with the point of simplification of driving system and IT application. Therefor it is essential to develop high voltage GIS using the motor-drive system to develop national heavy electric machine industries and catch up the technology to the advanced level. This paper therefore presents design and analysis of permanent synchronous motor for high voltage GIS, verifies the performance by the experimental test.
