Epilepsy is any of various neurological disorders characterized by sudden, recurring attacks of motor, sensory, or psychic malfunction with or without loss of consciousness or convulsive seizures. It could be divided into subcategories due to the international classification of epileptic seizure and the complex partial seizure, that is one of epileptic seizure subcategories, is characterized by elaborate and multiple sensory, motor, and/or psychic components accompanying the clouding of consciousness, prodrome, automatism, postictal confusion. This study reports a patient who was presumptive diagnosed as complex partial seizure by having the clouding of consciousness, prodrome, postictal confusion. We also diagnosed him as a ‘dianxian’ patient induced by sum deficiency of liver & kidney. This patient was treated by acupuncture to tonifying eum of liver & kidney and it achieved markedly improved symptoms.

A transitional trend of architectural elements which would happen naturally in a building may be a cue to the changes of the times. In this respect, this study is to investigate the transformation of types of windows and doors with the full-openable bay size in Korean Buddhist Temples and search for transitional process on types of windows and doors according to the flow of the times. As the results of this study, the following conclusion could be obtained. 1. The type of bunhap(connected door frame) Deul E-Yul-Gae doors + Deul E-Yul-Gas (life up) single windows would be changed from windows of a bay just beside a on the transition that the whole would be altered into the same type. 2. The type of Bunhap (connected door frame)Deul E-Yul-Gae doors + Bunhap (connected door frame) Deul E-Yul-Gae doors would be changed into Bunhap swinging doors that the whole of windows and doors could be opend very easily. 3. The type of Bunhap swinging doors + Bunhap swinging doors would be seen in the transition that windows and doors would be altered separately due to the exchange from window and doors of one of a middle bay or a bay just beside a middle bay to swinging doors and etc.

The methods of checking the exuberance of yang (潛陽法) are a kind of medical treatments which cure various symtoms caused by hyperactivity of liver-yang, at the same time used for treating apoplexy. Thus, I investigated the application of checking the exuberance of yang to treat stroke. The conclusions are as follows. We can find application of checking the exuberance of yang to apoplexy on Synopsis of the Gold Chamber. After Ye Gui who persisted the theory of endogenous wind, many physicians applied the method of checking the exuberance of yang and this method has usually applied with nourishing yin. The methods of checking the exuberance of yang are concretely applied as follows. 1) a portion of apoplexy involving the channels and collaterals, which is caused by deficiency of yin and wind-fire pathogen. 2) excessive-syndrome of coma accompanied by heat syndrome. 3) epilepsy caused old apoplexy. The majority of shells for example abalone shell, hawksbill shell, oyster shell, tortoise-shell etc. are the most frequent use of herbal drug which check the exuberance of yang. The precriptions of checking the exuberance of yang are Ho-jam-hwan(虎潛丸), Ko-bon-dan(固本丹), Cheon-ma-gu-deung-eum(天麻鉤藤飮), Chin-gan-sik-pung-tang(鎭肝熄風湯) etc.

This study analyzed the aspect of the decision of the Korean part of speech and the properties of the grammatical items based on "韓語通" which was published in 1909. "韓語通" is a Korean grammar book written by 前間恭作 who also published "校訂交隣須知" in 1904. "韓語通" is known for influencing of 'Otsuki grmmar(大槻 文法),' dividing Korean part of speech into eleven. Based on 'mood' and 'voice' we can assume that "韓語通" adopted Otsuki's grammar. '存在詞' is another clue that "韓語通" adopted Yamada's grammar. However, 前間恭作 persisted that Korean language is different from Japanese language. This view is different from 寶迫繁勝, 高橋亨, 藥師寺知? etc. This study tried to investigate the interchange of the two languages in historical study of Korean and Japanese linguistics during modern and contemporary period. For this purpose, we searched the aspect of the part of speech and analyzed the grammar items. In conclusion, we was able to light on how Japanese scholars approached to Korean grammar system in late 19th and early 20th centuries.

The purpose of this study was to broaden our knowledge on the productivity and costs of felling operation in three different harvesting methods(whole tree, tree-length and cut-to-length). Felling was conducted in three different harvesting methods with two workers who have different work experiences. Worker A and B have had felling experiences for about 5 years and 15 years, respectively. Felling productivity in whole tree method was $10.3m^3/SMH$ for worker A and $12.7m^3/SMH$ for worker B. Felling costs for worker A and B were $2,066won/m^3$ and $2,201won/m^3$, respectively. Although felling productivity of worker B in whole tree method was higher than worker A, felling costs of worker A were similar to worker B because the wage of worker B was more expensive than the wage of worker A (p>0.05). In tree-length method, felling cost of worker B were cheaper than that of worker A. Felling productivity and cost in tree-length method were $2.2m^3/SMH$ and $9,890won/m^3$ for worker A and $3.3m^3/SMH$ and $8,459won/m^3$ for worker B, respectively (p<0.05). In cut-to-length method, felling productivity and cost were $2.3m^3/SMH$ and $9,584won/m^3$ for worker A and $3.0m^3/SMH$ and $9,395won/m^3$ for worker B, respectively. Felling productivity of worker B was higher than that of worker A(p>0.05). Our preliminary results found that harvesting methods and worker's experiences highly affect on the productivity and costs of felling operations. These results should be useful for forest managers when planning cost-effective harvesting operations.

This study was conducted to develop a simulation model for estimating the amount of such products as round wood, dimension lumber and the residual wood biomass produced by processing the individual trees of Larix kaempferi. In the model, the stem volume is assessed using the taper equations of the species to estimate the stem forms. Then, the model simulates the conversion processes of logs to round wood or lumber and assesses the maximum amount of the wood products by the lumber dimensions or round wood size. Also the model provides information on the amount of residuals for kerf and slabs produced on the conversion processes for sawn timber or round wood. According to the results of an application of the model to a L. kaempferi process, the trees greater than 12 cm of DBH can be converted to logs for lumber or round wood production. For the trees, of which DBH is available for log conversion, the maximum amount of final products by dimensions were analyzed. In this analysis, production of the bigger dimension lumber was assumed to be preferred to that of the smaller or round wood. This model can be used for assesment of forest economic value through estimation of merchantable volume for the trees, and assessment of mill residues which has the potential to provide significant amount of feedstock for bioenergy production as well.

Two strategies for calculating economic feasibility are the machine rate and cash-flow methods. This study used the cash-flow method to evaluate the economic feasibility of the HAM300 yarding operation for extracting tree length logs in Larix kaempferi forest stands. In financial analysis based on 7-year cash-flow, the net present value and pay-back period method were used. We analyzed two scenarios: operating opportunities (50, 100, 150, and 200 days per year) and productivity change yield (7.5 and 10.5 ㎥/scheduled machine hour: SMH). The analysis indicated that high rates of return on extraction activity investment can be achieved when machines are used for >150 days per year. In addition, improved productivity (10.5 ㎥/SMH) increased financial feasibility compared to current productivity (7.5 ㎥/SMH) when machines were operated for 100 days per year. These results suggest that the appropriateness of HAM300 harvesting depends on the number of annual operating days and productivity.

원가 측면에서 유리한 저항점용접(Resistance Spot Welding)이 차체 용접에 80%이상으로 가장 많이 적용되고 있다. 첨단고강도강(Advanced High Strength Steel)의 저항점용접성 및 용접부 특성에 미치는 공정 변수의 영향에 대한 연구결과는 많으나, 합금원소의 영향에 대해서는 전무하다. 특히, Si는 DP(Dual Phase)강에 첨가 시 균일한 마르텐사이트의 분포를 촉진하는 원소로 저항 점용접성 및 용접부 특성에 영향을 미칠 것으로 예상되며, 이에 대한 연구는 보고된바 없다. 본 연구에서는 냉연 DP강의 저항 점용접시 중요한 인자 중 하나인 너깃경과 전단인장강도에 미치는 Si함유량의 영향을 검토하였다. 사용된 강재 및 용접기는 1.2mm 두께의 Si함유량(0, 0.5, 1.0, 1.5wt%)이 다른 인장강도 780~1000MPa급 냉연 DP강과 단상 AC용접기를 사용하였다. 용접조건은 ISO 18278-2규격에 따라 가압력 4kA, 초기가압시간 40cycle, 유지시간 17cycle로 고정하고, 용접전류만 변화하여 용접을 실시하였다. 너깃경은 용접부 단면을 컷팅 후 폴리싱 하여, 광학현미경과 Image Pro plus를 이용하여 측정했으며, 인장시편규격은 JIS Z 3137를 이용하였다. Si함유량이 증가에 따라 스패터 발생 전류는 감소했고, 너깃경은 직선적으로 증가했다. Si함유량 증가에 따른 너깃경 증가 이유는 저항(R) 측정결과, Si함유량 증가에 따라 모재의 저항이 높아져, 따라서 입열량($Q=I^2Rt$)이 많아지기 때문으로 판단되었다. 인정전단강도는 Si함유량 증가에 따라 직선적으로 증가했다. 이러한 이유는 Si함유량 증가에 따라 너깃경이 증가되기 때문으로 판단되었고, 너깃경과 인장전단강도 사이에 직선적 관계(PL(kN)=$3.2N_{dia.}$-0.81, $R^2$=0.93)를 가지고 있었다. 파단양상은 Si함유량에 상관없이 5.4kA이하에서는 계면파단이 일어났고, 6.0kA이상에서는 풀 아웃 파단이 일어났다. 계면파단주원인은 용접부 가장자리에 지름이 약 $5{\mu}m$이하의 예리한 노치가 존재하여 노치응력집중과 HAZ계면 근처에 미접합부가 존재하기 때문으로 판단되었다. 6.0kA이상에서는 예리한 노치가 없었고, HAZ부가 완전히 접합되어 있기 때문에 풀 아웃 파단이 일어난 것으로 판단되었다. 따라서, Si함유량 증가에 따라 적정용접전류 구간은 감소했고, 너깃경은 직선적으로 증가했다. 또한, Si함유량 증가에 따라 인장전간강도는 증가 했으며, 너깃경과 인장전단강도 사이에 직선적 관계를 가지고 있었다. 파단 양상은 Si함유량에 상관없이 5.2kA이하에서는 계면파단이, 6.0kA이상에서는 풀 아웃 파단이 일어났다.

This study was conducted in order to observe some descriptive epidemiological findings and causes of life-long labour force loss in the rural population of Korea, and to consider, on the basis of these observations, some principles of the necessary control measures. The total number of subjects in the study was 27,172, all family members of 4,174 households. The study population was located in the 81 counties, out of a total of 138 counties, where the college students conducted service activities during the summer of 1974. In each village area where these service activities were conducted, one household per student interviewer was randomly selected. Student interviewers were instructed on the contents of the questionnaire prior to the survey. The main contents of the questionnaire form included address, name, sex and age of each family members, and present life-long labour force loss, if any, of each family member. In cases of current labour force loss, the age of onset and causes were recorded. Of the total households surveyed, 8.9% had family members (1-4 in number) with life-long labour force loss. Of the total persons surveyed, the crude prevalence rate for life-long labour force loss was 15.1 per 1,000; and the age-standardized prevalence rates for male and female were 16.3 per 1,000 and 13.4 per 1,000, respectively. The rates, in both sexes, were gradually increased as the ages were increased. The prevalence rates per 1,000, in order, for life-long labour force loss by the causes were 10.2 for senility, 2.4 for impairment of extremities, 1.2 for chronic diseases of internal organs, 0.5 for other conditions of muosculoskeletal system, 0.4 for blindness in both eyes, 0.2 for impairment of spine, 0.2 for psychoses, and 0.1 for epilepsy. Among them the causes of impairment of extremities were stroke, poliomyelitis, accidents, arthritis and injury due to war operation, in that order of higher relative frequency. The frequency ratios by age of onset were also observed by the causes and sex.
