In this research, we investigated both present and potential entrepreneurs who are over 20 years old. The theme was that how businessmen's manners toward business and danger-perception have difference and are affected according to various factors. Besides, we also worked on the influence of manners toward enterprise and risk-perception variable on intention of starting and maintaining a business by using a decision-making model of consumers. The results are the followings. First, attitude toward enterprise was positive when the entrepreneur is man or unprofessional. This phenomenon was also observed if his or her parents had business foundation experience or he or she has self-realization motive rather than economical. Meanwhile, danger-recognition was high when the entrepreneur has no job, is more than 40 years old, has business background, or has affirmative enterprise attitude. Second, people who are man, have parents with business background or have self-realization motive on business foundation were more willing to start a business. Meanwhile, people who have affirmative enterprise manners, company with sales from 11 billion to 100 billion won or no business failure experience had high intention to maintain a business. Third, businessmen who are men, work in unprofessional job or have business experience had more strong desire to establish enterprise. Meantime, people who are old, have no jobs or have enterprise experience showed high danger-recognition level. At last, people who are men or jobless had strong will to start a business. So did the people who have positive attitude toward business or have parents who have business experience. Meantime, people with affirmative business manners or no experience of enterprise failure had strong intention to keep business.
A steady increase in the aged population poses a great challenge to nurses with their diversities of health care needs, especially of psychological nature, such as an alienation problems among the aged. The purpose of this study is to examine the nature of alienation problems among the aged in urban areas to provide basic informations for a better understanding of aged people. In this study, the investigator has tried to identify causes of alienation in the aged, and to determine the extent of alienation in relation to sex, family structure, religion, economic status and participation in social activities. The survey was done during the period from the last part of August to the end of September 1973. After a day's training, 10 interviewers have interviewed 210 stratified random samples of people over the age of 65 residing in Seoul with the free-ended questionnaire prepared by the investigator. The result of the study was tested by Critical Ratio. Following Hypothesis have guides formulation of the study: I. The extent of alienation in old man would be higher than in old woman, II. The extent of alienation in the aged who live alone would be higher than those living with their family. III. The extent of alienation in the aged who have no spouse would be higher than who live with their spouse. IV. The extent of alienation in the people without religious beliefs would be higher than the people with religious biles. V. The extent of alienation in the aged would be higher in proportion to decreased level of their economic productivity. Ⅵ. The extent of alienation in the aged who do not participate in social activities would be higher than that of the aged who actively participate. The analytic results of the study are as fellows: 1. The extent of alienation in woman was revealed higher than that of man by showing significant difference at P〈0.01 level. (CR=3.66) Accordingly hypothesis I was denied. 2. The extent of alienation in the aged wile live alone was revealed higher than that of the aged who live with their family by showing a significant difference at P<0.01 level. (CR=7.31) So hypothesis II was supported. 3. The extent of alienation of the aged who have no spouse was revealed higher than that of the aged who live with their spouse at the significant level of P <0.01. CR=4.65) Accordingly hypothesis III was supported, 4. There was no significant difference in the extent of alienation between the people with and-without religion. Thus hypothesis IV was rejected. 5. The extent of alienation in the aged was found to be higher in proportion to decreased level of their economic ability. a. The aged with greatest income showed least alienation b. The aged with no income had a greater extent of alienation than the aged with minimal income by showing significant difference at P <0.01 level . (CR=4.82) c. The difference between the greatest income group and the minimal income group was. found to be less significant than the difference between minimal income group and the-people without income. Thus hypothesis V was positively supported. 6. The extent of alienation in the aged who do not participate in social activities was higher than that of the aged who actively participate. (P <0.01, CR=6.24) According1y hypothesis Ⅵ was supported.

Marjolin's ulcer is a rare and often-aggressive cutaneous malignancy that arises in previously traumatized or chronically inflamed skin, particularly after burns. We experienced two cases after burns. Case I involved a forty eight year-old man who had suffered from a flame burn at the parietal scalp area, where had been initially described three years earlier as a full-thickness wound including the pericranium. The man consulted us for a persistent ulcerative and infected wound on the burned lesion during the last 24 months, which turned out on the contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) to be the squamous cell carcinoma with involving the skull and the dura mater. Although the posterior auricular lymph node was enlarged on the ipsilateral side, recent positron emission tomography (PET) CT did not show any metastatic lesion. It was impossible for us to resect the intracranial involvement of the tumor radically, and the postoperative PET CT still showed a focal fluorodeoxyglucose (FDG) uptake around the wall of the superior sagittal sinus. We think that an aggressive combined approach is essential for treatment in early stages for a high success rate, before the intracranial structures are involved because there is no consensus on the treatment for advanced disease, and the results are generally poor. Case 1 also did not involve a radical resection because of the intracranial invasion to the wall of superior sagittal sinus and the possibility of damage to the major cortical veins. He received adjuvant radiotherapy and must be followed periodically. Case 2 involved an eighty six year-old women who suffered from a painful scalp ulcer lesion after flame burns three years earlier. Unlike case 1, neither tumor infiltration into the dura nor lymph node enlargement was observed on the contrast-enhanced computed tomography (CT), magnetic resonance imaging (MRI), or positron emission tomography (PET) CT. We did a radical resection of the tumor, including the involved bone, and a cranioplasty with bone cement.

Since 1945, the periodical reforestation projects considered as the fundamental apparatus of the forest policy of the Government have been continuously carried out during last 40 years in Korea. As a result, some of the forests are ready to be harvested, especially in well-managed plantations as well as in the natural forests. This requires to pay more attention to harvesting the timber rather than planting trees. At the present, such timber harvesting operations such as cutting, felling, bucking, and skidding and yarding, particularly yarding operations in mountain areas with harsh terrains are in the most cases depend upon man power. However, the yarding operations should be more mechanized in the near future in Korea mainly because of the high cost of labour couppled with the lack of labour in forested areas. The Forest Work Training Center attached to the Forest Administration imported and tested the smallsized cable crane(K-300) with movable tower. The result of economic analysis of the yarding operation expenditures shows that the cable crane yarding costs more than the man yarding at the present time. As the labour cost will gradually increase and the efficiency of machine operation will improve, the results of the study indicates that the yarding operation by cable crane will be more cost-effective in the future.
This article is to search the aspects of realization and the characteristics of Gasa, Sijo, Japga among the Korean poetry genre based on Chohan-gosa. Chohan-gosa is a basic literary and historic discourse for the medieval intellectuals. The story had been realized its own literary value at almost every genres such as Chinese literature, novels, Gasa, Japga and Sijo etc. I focused on Gasa, Sijo and Japga among the genres in this article. First of all, I subjected to Wumiin-ga enjoyed in a area of boudoir culture from Gasa based on Chohan-gosa. I catch the meaning that the text has a characteristic that popularized history and normative ideology are mingled in through it. In the case of Sijo, I focused on the Sijo which Xiang Yu is appeared in because Xiang Yu has been most quoted person from people of Chohan-gosa. Xiang Yu was described as a strong man[hero] or a man who part with the beauty Wu. I understand that this point is caused by the theatricalized characteristic of the place where Sijo have been played. For the last time, Japga is played with the characteristic of stimulative reediting of the familiar normative ideology. Chohan-ga is based on contexts of former discourse eohan-yeonui but it was not plagiarized. Chohan-ga was organized for the way which attracted the interest of the public and stimulated the emotion of the public through using popular imagery or intensifying the sorrow.
Many types of occlusal splints are used for treatment of craniomandibular disorders. Most widely used splint among them is flat-type centric relation splint. Insertion of splint into the mouth may cause increasing of vertical dimension, masticatory muscle realignment and rearrangement of maxillo-mandibular relationship, so as a result of splint treatment, occlusal relation may vary whether you like it or not. From this point of view, occlusal state of patient shold be frequently monitored to prevent undesired or harmful effect during occlusal splint therapy. The purpose of this study was to investigate the effect of occlusal splint, especially centric relation splint, on the occlusal contact state after 3 months treatment. 32 patients with craniomandibular disorders who had unilateral symptoms participated in this study. To observe and record occlusal contact state, the author used T-Scan system (Tekscan Co. U.S.A.) at both pretreatment and posttreatment. The recorded date were analyzed with regard to contact number, contact force and contact time, change of anterior tooth contact and coincidence of first contact point with affected side were observed, too. Aan last, the subjects were divided into 2 groups and compared, according to average value of VAS index, with respect to joint pain, sound and limitation of movement, respectively. The collected date were statistically processed with SPSS and the result as follows : 1. Total occlusal contact number and force were not changed by occlusal splint therapy but total occlusal contact time decreased slightly. 2. There was a tendency of increasing number of subjects with anterior tooth contact after treatment and change of first contact point side were observed in as many as 40.6% of subjects. 3. There were no difference between higher and lower group of VAS index, and between pretreatment and posttreatment in each group, either.
The development project of Korean High Speed Train (KHST) was started in 1996. As a national research project, the KHST project aims for a development of the next generation prototype train that has a maximum speed of 350 km/h. The development process of prototype KHST including 7 vehicles was completed last year and currently the prototype train is on its way of test running over the test track with gradually increased speed. The prototype KHST uses the real time network called TCN (Train Communication Network) for exchanging information between various onboard control equipments. After 10 years of development and modification period, TCN was confirmed as international standard (IEC61375-1) for the electrical railway equipment train bus. In the prototype KHST, all major control devices are connected by TCN and exchange their information. Such devices include SCU (Supervisory Control Unit), ATC (Automatic Train Control), TCU (Traction Control Unit), and so forth. For each device that sends and receives data using TCN, a device has to find out whether TCN is in normal or failure state before its data exchange. And also a device must have a proper method of data validation that was received in a normal TCN state. This is a one of the major important factors for devices using network. Some misleading information can lead the entire system to a catastrophic condition. This paper briefly explains how TCN was implemented in the prototype KHST train, and also shows what kind of the fault diagnosis method was adopted for a fail safe operation of TCN system
Poria cocos is an edible and pharmaceutical mushroom with a long history of medicinal use in Korea. For the last 30 years, the domestic cultivated supply of Poria cocos has been unable to meet consumer demand, so Poria cocos is collected in mountainous areas and also imported from China. Thus, to increase the supply of Poria cocos, many artificial cultivation methods have been studied. In this study, Poria cocos is cultivated under different environmental conditions using plastic bags and the results compared. When cultivating Poria cocos at different temperatures (20, 25, 30 and $35^{\circ}C$) and using different numbers of plastic bag layers (1, 2), the most efficient cultivation conditions were a temperature of $25-30^{\circ}C$ and 2 plastic bag layers. The fastest growth was at $25-30^{\circ}C$, and the Poria cocos exhibited no weight change when cultivated using layers of plastic bags (1, 2).
The purpose of this paper is to assess the psychological status of the phoneme, syllable, and various postulated subsyllabic units in Korean by applying the Sound Similarity Judgment (SSJ) task, to compare the results with those in English, and to discuss the advantage and disadvantage of the SSJ task as a tool for linguistic research. In Experiment 1, 30 subjects listened to pairs of 56 eve words which were systematically varied from 'totally different' (e.g., pan-met) to 'identical' (e.g., pan-pan). Subjects were then asked to rate sound similarity of each pair on a 10-point scale. Not very surprisingly, there was a strong correlation between the number of phonemic segments matched and the similarity score provided by the subjects. This result was in accord with the previous results from English (e.g., Vitz & Winkler, 1973; Derwing & Nearey, 1986) and supported the assumption that the phoneme is the basic phonological unit in Korean and English. However, there were sharply contrasting results between the two languages. When the pairs shared two phonemes (e.g., pan-pat; pan-pen; pan-man), the pairs sharing the fIrst two phonemes were judged significantly more similar than the other two types of pairs. Quite to the contrary, in the comparable English experiments, the pairs sharing the last two phonemes were judged significantly more similar than the other two types of pairs. Experiment 2 was designed to conflrm the results of Experiment 1 by controlling the 'degree' of similarity between phonemes. For example, the pair pan-pam can be judged more similar than the pair pan-nan, although both pairs share the same number of phonemes. This could be interpreted either as confirming the result of Experiment 1 or as the fact that /n/ is more similar to /m/ than /p/ is to /n/ in terms of shared number of distinctive features. The results of Experiment 2 supported the former interpretation. Thus, the results of both experiments clearly showed that, although the 'number' of matched phonemes is the important predictor in judging sound similarity of monosyllabic pairs of both languages, the 'position' of the matched phonemes exerts a different influence in judging sound similarity in the two languages. This contrasting set of results may provide interesting implications for the internal structure of the syllable in the two languages.
Currently the universities in Korea have faced a critical situation for university entrants deficiency, especially in the fields of science and engineering. It will be act as a big crisis for the future national competences in science and technology. Therefore Kongju National University have been providing the engineering education program for highschool students during the summer vacation since 2001 as giving a chance of engineering laboratory experiences. During last 4 years, we have investigated the highschool students attended in engineering education program by questioning and contacting. This study is performed to improve the program by investigating their activities and thinking about engineering education. As results of the study, this manuscripts will summarized the characteristics of engineering education program and improvement schemes for the future application.
