The purpose of this study was to identify the response patterns of Health Locus of Control (HLOC) and to analysis of the health promoting behaviors depending on the response patterns of HLOC in Korean adults. The sample was composed of 300 healthy adults ranged from twenties to seventies. In data analysis, SPSS PC/sup +/ program was utilized for descriptive statistics, pearson correlation, ANOVA and cluster analysis. The results of the study were as follows : 1. The average scores of HLOC in Korean were HLOC-I : 24.12(range 6-30), HLOC-P : .21.72, HLOC-C : 17.46. 2. The total mean score of the health promoting behavior scale was 2.50 (range 1-4), and the mean scores on the subscales were ; self actualization 2.60, health responsibility 2.14, exercise 2.28, nutrition 3.16, interpersonal support 2.74, stress management 2.15. 3. The HLOC-I and health promoting behavior were correlated positively(r =0.184, p=0.001), and the HLO-C and the health promoting behavior were correlated negatively(r=-0.102, p=0.039). The HLOC-P and the health promoting behavior weren't correlated in the level of statistical significance. 4. The response patterns of HLOC in Korean adults were identified 6 types, such as pure internal, pure chance, believers in control, yea sayer, nay sayer, and complex control. The type of believers in control and the type of yea sayer were subdivided in two different types. The believers in control was the largest group(33.67%), and yea sayer was the next large group(26.33%). The pure chance and the complex control type was the smallest groups. 5. There was a significant difference in health promoting behavior depending on the response patterns of HLOC(F=2.67, p=0.010). There were also significant differences in 4 subscales of health promoting behavior : self actualization(F=3.12, P=0.003), health responsibility(F=2.15, P=0.038), nutrition(F=5.08, p=0.000), and interpersonal support(F=2.26,p=0.029). These results suggest that the response patterns of HLOC is the important factor to predict the level of health promoting behavior in Korean adults.

Recently, there was an increasing demand for an integrated access control system which is capable of user recognition, door control, and facility operations control for smart buildings automation. The market available door lock access control solutions need to be improved from the current level security of door locks operations where security is compromised when a password or digital keys are exposed to the strangers. At present, the access control system solution providers focusing on developing an automatic access control system using (RF) based technologies like bluetooth, WiFi, etc. All the existing automatic door access control technologies required an additional hardware interface and always vulnerable security threads. This paper proposes the user identification and authentication solution for automatic door lock control operations using camera based visible light communication (VLC) technology. This proposed approach use the cameras installed in building facility, user smart devices and IoT open source controller based LED light sensors installed in buildings infrastructure. The building facility installed IoT LED light sensors transmit the authorized user and facility information color grid code and the smart device camera decode the user informations and verify with stored user information then indicate the authentication status to the user and send authentication acknowledgement to facility door lock integrated camera to control the door lock operations. The camera based VLC receiver uses the artificial intelligence (AI) methods to decode VLC data to improve the VLC performance. This paper implements the testbed model using IoT open-source based LED light sensor with CCTV camera and user smartphone devices. The experiment results are verified with custom made convolutional neural network (CNN) based AI techniques for VLC deciding method on smart devices and PC based CCTV monitoring solutions. The archived experiment results confirm that proposed door access control solution is effective and robust for automatic door access control.

In spite of school science learning, the students' conceptions have not been changed easily. Therefore, to make students overcome their non scientific conceptions has been an important issue in science education. The purpose of this study was to identify the conceptions of students and teachers on the motion of the earth and the moon. The instrument was developed for estimating students' understandings of the concepts related to the motion of the earth and the moon. The validity of the instrument was examined by the specialists in Science Educator and Astronomer. At the same time, the two field trials had been executed, and the items were modified. Also, it consists of 12 items including 9 two-tier multiple choice items and 3 multiple choice items. The population of this study consists of 250 eighth-, 299 tenth-, 292 eleventh-grade students, 134 science teachers in secondary school. SPSS/PC+ was adopted for the statistical analysis. The type of misconceptions possessed students were as follows: 1) At 12:00 noon, the sun is directly overhead. 2) First quarter moon is a half of overall surface of the moon. 3) Air don't rotate with the earth surface because it keeps apart from the earth surface. 4) Summer is warmer than winter, because the earth is nearer from the sun in summer. 5) Whenever season is changed, the direction of rotation axis of the earth is changed. 6) The moon is the brightest at the position of new moon, because the distance between the moon and the sun is the shortest and the moon is received strongest sunlight. 7) The moon is not seen at the position of real full moon, because it is covered with shadow of the earth. 8) When the moon is not seen in the earth, sunlight is not reached at the moon. The major findings were as follows : 1) The middle school students had more misconceptions than those of high school students. And female students had more misconceptions than those of male ones. 2) The rate of correct answer and the type of conception in the tenth grade students were very similar with eleventh grade students. 3) The higher cognitive level, the better development of scientific conception and the less misconception. Also, the correlation coefficient between scientific conception score and GALT score was 0.57. 4) The students in scientific part had higher the rate of correct answer than those of students in human part and the former had less misconception than the latter. 5) The rate of correct answer about model and figure items was lower than descriptive ones, because they did not understand about figures itselves. These types of misconceptions will be used for science instruction and studies of other conceptions need.

Objectives : This study was performed to investigate the effects of Needle Electrode Electrical Stimulation (NEES) on ischemia-induced cerebrovascular accidents. After obstruction and reperfusion of ${\ast}{\ast}$ arteries in white mice, the amounts of necrosis and inflammation related substances IL-6, Caspase-3, and PARP, C-fos were measured in neurons of the hippocampus. The following results were obtained. Methods : This study used 21 male specific pathogen free (SPF) SD (Sprague Dawley) rats, 8 weeks of age and approximately 300 g in weight, that were given at least 1 week to adapt to the lab environment Each exposed artery was completely occluded with non-absorbent suture thread and kept in that state for 5 minutes. The sutures were then removed to allow reperfusion of blood. Test group is control group for comparison with the common carotid artery occlusion models, a GI group that underwent common carotid artery occlusion, and a needle electrode electrical stimulation (NEES) group that underwent NEES after artery occlusion. The GI and NEES groups were given 12, 24, or 48 hours of reperfusion before NEES. NEES device (PG6, ITO, Japan, 9V, current, 2Hz) was used to stimulate the right and left acupoint ST36 of the SD rats for 30 minutes while they were sedated with 3% isoflurane. An immunohistochemistry test was done on the forebrains of the GI induced rats. All the data collected from this study was symbolized and analyzed using a statistics processing program (SPSS 12.0K/PC). The level of significance was set at ${\alpha}$=0.05 and a T-TEST analysis was used to find out the effects of treatment on each of the groups: the normal group, the CVA induced group, and the treatment after CVA induction group. Results : Both PARP and C-fos immuno-reactive cells, related to apoptosis, were greater in the GI groups than the NEES group. Caspase and IL-6 immuno-reactive cells, related to inflammation, were greater in the GI and NEES groups than the control group. Conclusions : This research was conducted to study the effects of NEES on CVA due to ischemia. Occlusion and reperfusion was performed on the common carotid arteries of white rats, after which amounts of substances related to neuron necrosis and inflammation - PARP, IL-6, Caspase-3, and C-fos - were measured in the Hippocampus

전통적인 향기치료제로 쓰여 온 회향, 유향 그리고 노간주를 사용하여 최근 신기술로 평가되고 있는 초임계 유체추출법을 통해 생체 조절기능을 지닌 기능성 정유 성분을 추출하였다. 기존의 SDE 추출법과 비교하여 추출수율 측면에서 비교적 높은 결과를 얻어내어 정유 추출시 장차 SDE 추출법을 대체할 신기술로 평가되었다. 추출용매를 사용해야 하는 SDE 추출법과는 달리 무색, 무취인 $CO_2$를 이용하여 정유 성분을 분리하는 초임계 추출법은 인체에 무해한 정유 성분을 얻을 수 있다는 것이 가장 큰 장점이라 사료되며, 분리된 정유 물질에 대해 성분 분석 결과 대부분이 휘발성 알코올 계열에 물질임을 확인할 수 있었다. 정유 성분들에 대한 생리활성 실험결과 항암, 항 돌연변이 그리고 신경활성이 아주 높은 것으로 나타나 aroma-theraphy로서의 가능성을 제시하였다고 사료된다. 나아가 이 정유성분에 대한 in vivo 실험을 통해 기초 의약품으로서 연구가 수행되어진다면 전통적인 치료제로서 사용된 천연물에 대한 현대적 가치부여가 가능하다고 생각된다.

Objectives : By analyzing the affects of the mother's oral care to the caries experiences of the elementary school children, To looking for the way to prevent dental caries in the primary school, to provide baseline data to perform the associated oral health education. Methods : Between the 3,676 children's dental check-up data and the 2,934 survey of parents from 9 elementary schools in the the Gyeonggi Province, the exactly matching data of 2,358 pairs, children versus mothers, were analyzed during the period, 2009 May 4 to July 20, By using the PASW 18(SPSS-PC 18), Frequency analysis of the collected data, and cross-analysis, ANOVA, Bonferroni post-analysis was performed. Results : The findings of the study were as follows. 1. In children, the ratio(DMF rate)of the dental caries experience in permanent teeth, appeared higher for men than women. Divided by grade level, the ratio of caries experience in the permanent teeth(DMF rate) generally appear higher in older than young. Thus between the child's gender and grade level by the ratio of caries experience in the permanent teeth(DMF rate) showed the statistically significant differences (p<0.05). 2. Between the socioeconomic characteristics of mothers and the children's level of dental caries experiences, not showed the statistically significant difference.(p>0.05). 3. The significant difference showed between the dental caries levels of the children and the mother's oral health care behavior - a toothbrush replacement period, mother's broken teeth, mothers guidances of the brushing after snacks for children(p<0.05). Conclusions : The mother's oral health attitudes and behaviors can affect to their children's oral care habits. Therefore The mother themselves should have the right proper habit of oral health care, so that in oral health care mothers should be the model for their children. Institutionally more systematic and detailed oral health educational program in conjunction with the family is needed.

목적: 본 연구는 Q-방법을 적용하여 배우자 사별여성들의 경험에 대한 주관성 유형을 확인하고 그 특성을 알아보고자 수행되었다. 방법: Q-모집단은 문헌고찰과 사별한지 2년 미만의 배우자 사별 여성 5인의 면담을 통하여 209개의 진술문을 추출하여 구성되었다. Q-표본은 Q-모집단 진술문들을 통합, 범주화한 후 자문을 거쳐 46개의 진술문으로 선정되었다. P-표본은 사별한지 2년 미만의 배우자 사별 여성 13인을 대상으로 선정되었으며, 2004년 10월부터 2006년 12월까지 연구자가 개인면담을 진행하였다. 이들 P-표본 대상자들은 Q-표본 진술문을 강제정규분포 방식으로 Q-분류하였다. 자료는 Quanl PC 프로그램으로 처리하여 유형을 분류하고, 그 특성을 파악하였다. 결과: 배우자를 사별한 여성들의 경험은 2개의 유형 즉, 상실고통형과 수용적응형으로 분류되었다. 상실고통형은 비교적 젊은 나이의 남편과 예측하지 못한 사별을 한 후 얼마 되지 않는 여성들로, 이들은 남편의 빈자리를 정서적, 가정적, 사회경제적 영역에서 크게 느끼면서 불안감, 외로움, 죄책감 등이 높은 특성을 지녔다. 수용적응형은 어느 정도 예측된 고인의 죽음을 수용하는 태도를 보이며, 어려움을 신앙과 성숙으로 극복하여, 긍정적으로 세상을 대하며, 새로운 삶에 재적응하는 모습을 보여주고 있다. 결론: 이상의 연구결과 배우자를 사별한 여성들은 공통적으로는 모두 사별로 인한 슬픔과 고통을 느끼고 있었으나 죽음의 성격, 사별기간, 개인 성격과 영적상태에 따라 상실고통형과 수용적응형으로 유형화할 수 있었다. 따라서 사별가족관리 전문가들은 배우자를 사별한 여성들의 유형을 파악하여 각 유형에 맞는 사별돌봄 전략을 개발하여 섬세한 돌봄을 제공하여야 하겠다.
