The purpose of this study is to quantitatively evaluate the amount of carbon storage for trees in forest ecosystem to support the foundation for carbon neutrality implementation in Korea National Park. It targeted 22 national parks designated and managed as national parks in Korea, and conducted research on forest trees in the terrestrial ecosystem among various natural and ecological carbon sink. The survey and analysis method followed the IPCC guidelines and the National Greenhouse Gas Inventory in Korea. The amount of tree carbon storage in the forest ecosystem of Korea National Park was confirmed to be about 218,505 thousand CO<sub>2</sub>-ton and the amount of carbon storage per unit area was 570.8 CO<sub>2</sub>-ton per hectare. Compared to 299.7 CO<sub>2</sub>-ton per hectare, the average carbon storage per unit area of the entire Korean forest, it was found that about twice as much carbon was stored when assuming the same area. In other words, it means that the tree carbon storage function of the national park is about twice as high as that of the average tree carbon storage function of entire Korean forest. It has great implications in Korea National Park not only provides biodiversity promotion and exploration services as a national protected area, but also performs excellent functions as a carbon sink.

We estimated the potential area roof greening in Gyeonggi-do that will mitigate the heat island effect. The estimation was based on building age, roof shape, and building use which were recorded in the building register from "Sewoomteo, the Building Administration System in the Ministry of Land, Transport and Maritime Affairs. The estimated potential roof greening area in Gyeonggi-do was approximately 102.5㎢ assuming that the buildings for residence, public, education(school), office, shopping mall are appropriate for roof greening. The area occupied by apartment buildings over six-story was 76.3% of the potential roof greening area 10.2% for individual houses, 5.9% for under five-story apartment buildings, and 3.7% for school buildings. The result indicated that it is residential buildings that we need to pay attention for roof greening, especially high-rise buildings over six-story. Greening of the whole estimated area, 102.5㎢, in Gyeonggi-do will result in the increase of green space per capita by 8.74㎡. This is 1.65 times greater than the area of current urban parks, and 1.97 times greater than the total area of neighborhood parks, children`s parks, and pocket parks. Greening of the estimated roof area will increase green coverage of urban area by twice, adding to current green coverage of the urban areas, 11.3%, in 10 major cities. In particular, the effect of roof greening would be remarkable in inceasing the green space of Anyang City, Gwangmyeong City, and Guri City where neighborhood park area falls short.

이 연구는 트레드밀 운동과 키네시오 테이핑의 효과에 따른 폐활량의 변화를 알아보기 위해 26명의 비흡연자가 참가하였으며 키네시오 테이핑을 적용하지 않은 그룹과 키네시오 테이핑을 적용한 두 그룹으로 무작위로 배정하고 각 군들을 주 3회 6주간의 트레드밀 훈련을 실시하였다. 실험 전과 후, 스파이로미터를 사용하여 키네시오 테이핑의 적용 따른 폐활량 변화 효과를 측정하였다. 이 연구의 결과를 종합해보면 키네시오 테이핑을 적용 그룹에서 적용하지 않은 그룹에 비해 FVC, FEV1에서 유의한 증가를 보였다. 이러한 결과는 건강한 성인에서 키네시오 테이핑을 적용한 경우 키네시오 테이핑을 적용하지 않고 트레드밀 운동을 한 경우보다 폐활량의 향상에 효과적이라고 생각되어진다. The purpose of this study was to investigate the variation of vital capacity(VC) according to the effects of kinesio taping with treadmill exercise. Twenty-six non-smokers were participated in this research and these subjects were randomly assigned into two groups. To measure the VC variation effects of kinesio taping, spirometer was used. The collected data were analyzed statistically by using a paired Mauchly test and repeated measure ANOVA. The results of this study were as follows; A group: treadmill with kinesio taping B group: treadmill without kinesio taping. Between A and B, there were significant differences. In the case of A group, there was 11.66% increase of VC, during 3 weeks experiment(p<.01). In the case of B group, there were significant differences, 3.35% increase of VC, during 3 weeks taping intervention(p<.01). After 6 weeks experiment, the improvement of VC shown a significant difference with intergroup (p<.05). From this result, it was revealed that treadmill exercise with kinesio taping was effective to improve VC to healthy adult than treadmill exercise without kinesio taping.

저자들은 환청과 망상을 주소로 정신과를 방문한 진행성 핵상 마비 환자를 진단하고 치료하였다. 진행성 핵상 마비는 보행 장해, 치매, 수직성 안구 운동의 장해가 특징적인 증상이며, 아직까지 특별한 치료법은 알려져 있지 않다. 정신과적 증상으로는 인지기능의 장해, 정동 및 행동의 변화, 수면 장해, 정신병적 증상 등이 있으며 정신분열병과 비슷한 증상을 보이는 경우는 극히 드물다고 한다. 본 증례에서는 파킨슨 증상과 정신병적 증상이 비슷한 시기에 발현된 진행성 핵상 마비의 예를 보고하면서 진단적 중요성을 강조하고자 한다. We have experienced a rare case of progressive supranuclear palsy with hallucination and delusion. The common manifestations of progressive supranuclear palsy are gait disturbance, mental change and sign of vertical ophthamoplegia but no efficacious therapy has been known. Neuropsychiatric symptom clusters include cognitive impairment, affective and behavioral changes, sleep disturbance, and psychotic symptoms. Though schizophrenia-like psychosis has been reported but this is certainly rare. Addressing a case of progressive supranuclear palsy, in whom parkisonian symptoms appeared with concurrent psychotic symptoms, we emphasize accurate diagnosis.

This paper presents a back-end system of hypermedia authoring system for courseware development. For the design, repersentative hypertext reference models, the Dexter model and the HAM(Hypertext Abstract Machine) which belongs to Campbell & Goodman model were analyzed. Based on those models, data objects, attributes, and operations of back-end system were designed and implemented. Because the application area of this system is on computer based education, the path mechanism is enforced for the various educational strategies. In order to reduce the user disorientation and cognitive overheads in navigating hypernetwork, filtering, backtracking and history mechanism were implemented.

The purpose of this paper is to develop an optical fiber displacement sensor. An optical fiber displacement sensor is based on simple principles. Electrical signal responds to the optical flux change due to the displacement change between a target and a sensor probe. In this paper, the performance of optical fiber displacement sensor has been investigated. Firstly, optical loss has been measured before and after polishing optical fiber endface. Secondly, allowance of optical fiber bending has been tested. Thirdly sensitivity and linear range of the sensor has been found out according to the shape of cross section of optical fiber.

Hydrogen embrittlement (HE) mitigation on the low alloy steel was studied using electrochemical technique. This method can be applied to reduce HE susceptibility. Hydrogen induced cracking (HIC) characteristics of the low alloy steel was investigated in aerated and deaerated borate buffer solution (0.3M H₃BO₃ + 0.074M N₂B_(4)O_(7), pH 8.4). The electrochemical properties of the low alloy steel showed passive behavior in this environment. By performing galvanostatic and potentiostatic test, hydrogen was charged and discharged to specimens respectively. By applying the potential of +630 mV_(SCE), the accumulated hydrogen was eliminated electrochemically. A specimen discharged for 24h indicated the efficiency of the hydrogen discharge up to 99.9%. Slow strain rate tests (SSRT) results showed that a specimen with higher hydrogen concentration revealed inferior mechanical properties such as shorter time to fracture, lower elongation, ultimate tensile strength and yield strength values. Furthermore, SEM fractographs revealed that the higher the hydrogen concentration is, the more probable the features of brittle fracture are. (Received July 26, 2004)
