This study was carried out to analyze the characteristics of forest environmental and stream morphological factors by using the quantification theory (I) for prediction of the suitable dam site. The results obtained from this study were summarized as follows; The selection of suitable site for erosion control dam was estimated by normalized score of each category. And the prediction method of suitable site for erosion control dam divided into class I (Very suitable site), II (Suitable site), and III (Poor suitable site) for the convenience of use. In conclusion, if we select the suitable site for construction of erosion control dam for disaster prevention, we could save the loss of tremendous budget, avoid the poor suitable site due to subjective judgment, and it would promote the functions of erosion control dam.

The purpose of this research Is to clarify the relationship between leisure activity participation, job stress, social support and subjective well-being among security agents. 356 (92%) questionnaires were obtained from 12 private security companiesin metropolitan Seoul. The conclusion follows. First, the frequency of participation in activities on the subjective well-being reflects the direct influence. and period by participating in the job stress on the subjective well-being reported more negative affect, in other words, Job Stress is reduced, social support and subjective well-being is increased. Second, job stress has a negative effect as a parameter to subjective well-being and participation in the period, in other words, subjective well-being is decreased by the more get job stress. Third, social support affects the subjective well-being, leisure activity participation and social support that have no relationship, In other words, subjective well-being is increased by the more get social support. Fourth, frequency and duration of participation in leisure activity directly and indirectly affects to subjective well-being. increasing the frequency of participation activities make that subjective Well-being is increased, increasing the participation period makes that job stress is reduced, job stress reduction make that subjective well-being is increased, and increasing the social support makes that subjective well-being is increased.

The purpose of this study is to present foundational data to promote the cultural welfare status of youth. The actual condition of the youth's cultural welfare was investigated by investigating the degree of youth's cultural welfare satisfaction and needs by regional groups. A total of 1486 questionnaires were used for the final data analysis. The analysis revealed the following results. 1. Actual conditions of adolescents cultural welfare. 1) Among various cultural activities, adolescents find leisure and social activity, artistic, mass media and video-media activities very boring and one-sided, Instead, they have greater interest in computer- and Internet-related activities, such as getting and sharing information and communication. 2) While adolescents living in urban areas benefit from well developed social infra-structure, those living in rural areas seldom take advantage of it. 3) The obstacles against cultural welfare of the youth can be categorized as: 'lack of money,' 'lack of time,' and 'lack of cultural facilities. ' In urban areas 'lack of time' becomes an issue, whereas in rural areas 'lack of money' and 'lack of cultual facilities' are important. 2. Degree of cultural welfare satisfaction of the youths. Youths generally appear either 'unsatisfied' or 'neutral' concerning their satisfaction degree about leisure and social activity parts, and art and play-activity paris. On the other hand, they appear 'neutral' concerning their satisfaction degree about computer- and Internet-related information and communication parts, and mass- and video-media activity parts. In addition, urban youths show a higher degree of satisfaction than rural youths. 3. What the youths need To improve their culture welfare status, they need a lot of supplements for cultural activity in the form of cultural infra-structure. Regarding the cultural infra-structure, rural youths need more than urban youths.

Aromatherapy는 향을 이용하여 생리적 및 심리적 효과를 나타내는 치료법이다. 향의 종류에 따라 여러 효과들이 나타나고 있는데 본 연구에서는 이완 유도향 제품을 개발하기 위해 자율신경계로부터의 신호인 Galvanic skin resistance(GSR), 피부온도, 심박수 등과 뇌파에서의 변화를 측정하여 이완의 정도를 측정하고자 하였다. 실험방법은 4 종류의 aromatherapy용으로 조제된 복합향(#2033, #2026, #11, #13)을 이용하고 피검자는 후각기능이 정상이며 물리적 및 심리적 stress가 없고, 음주, 담배를 3일전까지 경험이 없는 군을 택하였다. 향을 주는 시간은 1분으로 하였으며 순서에 의한 효과를 없애기 위해 4 종류를 random order에 의해 실시하였다. 대조군으로는 증류수를 이용하여 실험 전, 실험 중, 실험 후에서 각각 측정하였으며 또한 각성효과가 좋은 jasmine과 이완 효과를 보이는 lavender를 같은 protocol로 시행하여 이완의 효과를 비교하였다. 뇌파는 FFT분석에 따라 각 주파수 영역 즉 beta, alpha, theta, delta로 나누어 분석하였다. Jasmine과 lavender의 이완 효과에서는 GSR의 변화와 HRV의 변화를 보고한 바 있다(백,1998). 또한 심리불안 효과와 향 이미지 검사를 동시에 시행하여 주관적지표로 삼았다. 실험 결과에서는 이러한 4 종류의 향은 모두 GSR의 현저한 감소 효과를 보였으며, 심박수와 피부온도의 감소경향을 나타내었다. 자율신경계 반응에 따라 4 종류 향의 이완 효과의 순서를 결정할 수 있었다. 주관적 검사와의 상관관계도 잘 나타났으며 이미지는 이완 정도와 섬세하다 항목이 잘 반영되었다. 뇌파의 변화에서는 의미 있는 변화는 보이지 않았다. 결론적으로 relaxation 효과는 GSR를 비롯한 자율신경계지표에서 잘 반영되었다.^2$=.792가 되었다. 설명되는 누적분산값은 67.18%였다.주관적 평가의 결과와 객관적 평가 결과를 이용해 마직물의 태를 평가하는 산출식을 제시하였다. 태 평가치의 경우 16가지 특성치를 모두 넣는 방법과 stepwise 방법, 또 Kawabatark 사용한 순차적 군 회귀법의 세가지 방법의 회귀식 중 16가지 특성치를 모두 넣는 방법의 결정계수가 가장 높았다.tosterone농도는 107.7$\pm$12.0 pmol／l이었고, 남성의 타액내 농도는 274.2$\pm$22.1 pmol／l이었다. 이상의 결과로 보아 본 연구에서 정립된 EIA 방법은 RIA를 대신하여 소규모의 실험실에서도 활용할 수 있을 것으로 사려된다.또한 상실기 이후 배아에서 합성되며, 발생시기에 따라 그 영향이 다르고 팽창과 부화에 관여하는 것으로 사료된다. 더욱이, 조선의 ${\ulcorner}$구성교육${\lrcorner}$이 조선총독부의 관리하에서 실행되었다는 것을, 당시의 사범학교를 중심으로 한 교육조직을 기술한 문헌에 의해 규명시켰다.nd of letter design which represents -natural objects and was popular at the time of Yukjo Dynasty, and there are some documents of that period left both in Japan and Korea. "Hyojedo" in Korea is supposed to have been influenced by the letter design. Asite- is also considered to have been "Japanese Letter Jobcheso." Therefore, the purpose of this study is to look in

Purpose : This study was done to evaluate xerostomia fellowing intensity modulated radiotherapy for patients with head and neck cancer, and to analyze the correlation between the dosimetric parameters and xerostomia parameters. Materials and Methods : From February till October 2003, 13 patients with 3 months of follow-up were evaluated for xerostomia after being treated for head and neck cancer with IMRT. Their median age was 57 years(range: 43$\~$77). Xerostomia were assessed with a 4-question xerostomia questionnaire score (XQS) and a test for salivary flow rates (unstimulated and stimulated). The patients were also given a validated LENT SOMA scale (LSC) questionnaire. The evaluations were completed before radiation therapy (pre-RT) and at 1 and, 3 months after radiation therapy (RT). We evaluated xerostomia at pre-RT, 1 and, 3 months after RT. The association between the xerostomia parameters (XQS and LSC) and salivary flow rates (unstimulated and stimulated: USFR and SSFR) was assessed at 1 and 3 months after RT. Resrlts : All 13 patients showed no significant changes in XQS, LSC and Salivary Flow rates. As a result, we couldn't find out about xerostomia development. Based on the total mean parotid dose, 3,500 cGy, we divided these patients into two groups. The 8 patients (<3,500 cGy) showed no significant changes in XQS, LSC and Salivary Flow rates However, in 5 Patients ($\geq$3,500 cOGy), there was a significant increase in USFR and, SSFR at 3 months after RT, and for the XQS and, LSC at 1 and 3 months after RT. The correlation between XQS and, LSC, and USFR and, SSFR in ail patients (13) was significant at 3 months after RT. The correlation had a tendency to the decrease for USFR and, SSFR in proportion to the increase of XQS and, LSC. Conclusion : Based on the results of this study, IMRT seem to be an effective treatment to significantly decrease the xerostomia. XQS and, LSC seem to be a effective tool for predicting the xerostomia. A total parotid gland mean dose of <3,500 cGy should be a planning goal if substantial sparing of the gland function is desired. Furthermore, patients should be enrolled in a study to define a more accurate threshold dose for the parotid gland.
