The purpose of this study is to investigate the perception and need on home economics education curriculum by middle school students and to supply the basic data for progress of home economics education program. The major result of this study can be summarized as follows. 1. Students have the perception that home economics education is to prepare them for their future family life than to regard job education. 2. In students' need on contents of home economics curriculum, food and nutrition is mostly preffered, and the next is human development and family relationships, clothing and housing are leastly preffered. 3. Students' major complaint of home economics education is the lack of practice programs of curriculum and they want to learn the subject by the more and various practise than the knowledge and theory.

This study was designed to investigate the relation of variables of home environment to mental health of adolescences. The subjects employed were 868 students who are 1st grade of 10 highschools in Taegu city. The measurement of mental health consisted of Korean manual of Symptom Checklist-90-revision. Data were analyzed according to mean, standard deviation, t-test, X²-test, one way and two way ANOVA by using SAS and SPSS Programs. The results are as follows : 1. The healthy group of all the subjects was 49.42% and the other mental health condition showed 25.46% for protective group and 25.12% for unhealthy group. 49.42 percents of all the subjects showed the perfect healthy condition and the other 50.58% showed the unhealthy symptoms. The psychoticism was highest in the unhealthy group. The academic highschool students showed the higher points than that of vocational highschoolers in the obsessive-compulsive symptoms(P<.01) and depression(P<.05). In the condition by sex, the mean value of females(54.07) was somewhat higher than that of males(51.03). The mental health by sex showed the significant difference to the other 7 symptoms besides the somatization and phobic anxiety and to the mental health by group(P<.001). 2. The socio-economic status of family didn't show the significant difference to 9 mental health symptoms and groups. The order of birth didn't show the significant difference to 9 mental symptoms and to mental condition by group(P<.05). On the one hand, family pattern showed the significant difference to the depression(p<.01)and anxiety(P<.05)of 9 symptoms for mental health. Its difference in mental health condition by group appeared significantly(P<.05) The condition of parental absence showed the significant difference to interpersonal sensitivity(P<.05), anxiety(P<.05), paranoid ideation(P<.01)and psychoticism(P<.05)of 9s. The absence of father showed the significant difference to the other 7 symptoms besides anxiety and phobic anxiety, also to the mental health by group.(P<.01) However, the absence of mother didn't show the significant difference to 9 symptoms for mental health and to mental health groups. Of the process variables of home environment, the father's child rearing attitude showed the significant difference to 7 symptoms besides somatization and interpersomal sensitivity of 9 symptoms for mental health. The mother's child rearing attitude showed the significant difference to the obsessive compulsive(P<.05). depression(P<.05), hostility(P<.01) and the psychoticism(P<.05), but didn't show the significant difference to the mental condition by group(P<.05). The type of concern of parents showed the significant difference to 8 symptoms besides the phobic anxiety and to mental health by group(P<.05). The degree of satisfaction on their fathers and mothers showed the significant difference to 9 symptoms for mental health and to group for mental health. The marital relation between father and mother showed the significant difference to 7 symptoms besides the anxiety and phobic anxiety and to mental health by group. The domestic peace showed the significant difference to 9 symptoms for mental health and to mental health by group(P<.001). Accordingly, the mental health of adolescence seems to be more affected by the process variables rather than by the status variables of home environment.

The object of this study is to figure out charactristics on the deformation Haeundae beach through a statistical analysis by using leveling and water depth surveys which were carried out seven times. The result of the analysis is shows that a depositional summer-type-beach is built up from spring to summer and a erosional winter-type-beach up from fall to winter. From the analysis it can be concluded that the erosion is affected by moving drift sands along on-offshore direction and the deposition is affected by those along the longshore direction. Therefore, the most suitable protection method in Haeundae beach would be Zetty, Head-land or a composition structure incorporating detached breakwater method which is the suitable method for the protection of erosion along the longshore direction.

The security of Busan waterfront space mostly depends on the reclamation of the coastal zone. The temperature variation is caused by the reclamation, and the model formula of correlation with the reclamation quantity in the coastal zone of Busan is derived(X=logl0α, α=the total of the reclamation quantity). For the determinating coefficient γ²=0.86609 Y= - 157.06659 + 91.766855X - 16.6357X² + 1.0534768X³- 0.006741X⁴ From this, the later temperature increase followed by increase of the reclamation quantity is predicted.

波浪과 흐름이 共存하는 大河川 河口部인 洛東江 河口域에서 洛東江 河口둑을 基点으로 波浪, 흐름, 地形變動, 潮流, 洪水位等을 評價基準으로 하여 災害에 대한 基本的인 評價를 實施했다. 波浪, 潮流, 洪水位等이 水位上昇을 透發시켜 周邊地域을 浸水시킬 수 있는 危險性의 與否를 實測과 數値計算을 통하여 實施하였다. 地形變動은 實測만을 통하여 地形變動率을 調査하였다. 資料를 分析한 結果 洛東江 河口地域은 波浪, 흐름과 波浪이 共存하는 領域으로 區分된다. 數値計算結果에 의하면 河口部에서의 來襲波高가 直接 河口둑 水門과 주변構造物에 미치는 影響은 크지 않았다. 또한, 3次元 波高分布를 볼 때 河口 水路를 따라서 거슬러 올라오는 波浪의 影響은 거의 없었다. 洪水位와 流速은 災害를 透發시키는 主要因子로 評價되었다. 波浪에 의한 異常高潮와 漲潮流와 潮汐의 滿潮時間 및 最大洪水量이 時間적으로 一致되는 境遇, 河口둑 周邊地域의 水位 上昇과 流速의 停滯現狀으로 浸水狀態가 發生한다. For the investigation of inundation disasters by wave setup in the Nakdong Estuary of the Large River which waves and currents are coexist, the wave surveying data was analyzed and the numerical model was applied to the Estuary. In this study, the result of surveying data analysis shows that waves have little effect on the surroundings. As the result of numerical computation, waves have seldom direct influence upon the barrage and its gates. Also, according to three dimension distribution of waves, it is found that coming up waves along the Estuary channel and the setup of waves have seldom effect barrage structures.

수면, 기억 그리고 학습의 연관성은 실제 매우 복잡하다. 많은 연구에도 불구하고 명확한 연구결과는 아직 없다. 우리는 이 연구에서 평소와는 달리 시험 전날 수면 변화 양상이 집중력에 어느 정도 영향력을 미치는지 알아보고자 하였고, 이를 이용해 효율적인 수면 관리를 할 수 있는 기초자료로 삼고자 하였다. 동국대 의대 본과 1학년생 중 지원자 30명과 본과 2학년생 10명을 대상으로 평상시 상태와 시험 직후 수면이 부족한 상태에서 각각 K-PES TEST를 실시하여 총 8항목에 걸쳐 암기력, 판단력, 단순반응의 변화정도를 검사하였다. 또 설문조사를 병행하여 결과에 영향을 미칠 수 있는 다른 인자들도 파악하였다. 수면량에 대한 부호 숫자 짝짓기(순간 판단력)을 검사한 결과, 인간의 최대 생리학적 기능은 꼭 수면부족에 의해 좌우되는 것은 아니다. 그러나, 수면감소는 피로를 증가시키고, 동기부여를 감소시키나 단, 새로운 사실을 학습하는 데에는 큰 영향을 끼치지 않는다. 즉, 수면부족으로 장시간 깨어있는 것은 정확성과 반응성을 떨어뜨린다. 흡연에 대한 부호 숫자 짝짓기(순간 판단력)을 검사한 결과, 니코틴의 수면에 대한 상호관계는 알려지지 않았고, 인간의 감정이나 의식, 인식에 영향을 주는 것으로 알고있지만, 장기적은 측면에서 흡연이나 알코올은 인식능력과 무관한 것 같다. 카페인에 대한 숫자 외우기(암기력)검사 결과, 카페인은 spacial selective attention에는 특별한 영향을 주지 않지만 지각과정이나 주의 집중에 큰 효과를 주며, 인간의 의식 수행에 긍정적인 효과를 준다. 즉 카페인은 활력, 혼란, 피로상태를 변화시키고 visual analog scales에서 휴식상태에 가까운 양상을 나타낸다. 또 48시간 동안 수면을 취하지 않은 사람에게 카페인은 집중력과 장시간의 좋은 기분을 유지하게 하였다. 그러나 규칙적, 비규칙적으로 먹는 사람간에는 인지수행력의 차이를 보이지 않으며 상용자에서는 상당한 내성이 보인다. 수면패턴에 대한 숫자 더하기(순간 판단력)검사 결과, 집중력은 수면패턴에 의해서도 영향을 받고, 수면패턴이 바뀌게 되면 순간판단력을 저하시킨다. This study was performed to evaluate relationship of sleep and attention, and to control sleep effectively. We conducted a K-PES test of 40 medical students. K-PES contains eight elements, for example, simple response, selective response, color pairing, OddEven discrimination, number addition, number-symbol matching, memory, right-tapping, left tapping. Through these, we tested changes of memory, judgement, simple response. And we conducted a questionnaire survey to exclude bias. Results are as follows. As a results of number-symbol matching test, we know that sleeplessness is not complete responsible for physiologic function for humans. But, decreased sleep increases fatigue and decreases motivation, but no influence on learning new materials. So, long term sleeplessness decreases precision and responsibility. As a results of number-symbol matching test on smoking, a relationship of nicotine and sleep is not certain. A point of view in long term period, smoking and drinking is not related cognition, even if we know that those influence mood, consciousness and cognition. As a results of memory work test on caffeine, caffeine does not influence spacial selective attention, but mainly does perception, attention and consiousness process. Namely caffeine changes energetic activities, chaos, fatigue states and shows resting state in visual analog scales In sleeplessness for 48 hours, caffeine produced attention and good mood for a long time. But, in case of cognitive process no significance shows in regular or irregular diet. Regular diet shows high resistance. As a results of number addition test on sleep patterns, seep patterns influence attention, changes of sleep patterns decrease a moment judgement.
