Author have measured the depth of gingival sulcus of the primary teeth. 333 teeth were selected from the children who attended on the department of pedodontic, College of dentistry, Yonsei University, and kindergarten children at Won Ju city aged from 1 year 8 months to 10 year 2 months. 1998 point were measured. The results were as follows. ; 1. Facial surface was the shallowest in sulcus depth compared with other surfaces. It was 1.56 mm. The depth of sulcus in lingual surface was deeper than facial. 2. The deepest part of each surface was mesial and distal, There were no statistical differences between mesial and distal part of the sulcus depth. 3. The mean sulcus depth of each tooth was as follows. Primary central incisor.....1.71mm. Primary canine....1.75mm. Primary second molar.....2.03mm. 4. The mean sulcus depth of upper was 1.86mm, and the lower was 1.76mg. The upper tooth was deeper than lower in sulcus depth. 5. The lower primary central incisor had the shallowest sulcus and the upper 2nd primary molar had the deepest compared with other tooth. 6. There wasn't specific statistical differences between the age groups of primary dentition and mixed dentition.

Socks and stockings played a role as the first clothing covering foots and legs in ancient times. During the Middle Age they have represented clothing for legs and have been transformed into plasticity and aesthetic outlets for human beings aesthetic desire. Recently in around 1980 various experiments have been tried on them as part of total fashion changing as fashion trends changes. In 1990s the industry of socks and stocking in Korea has grown up as niche market, increasing the export amount twice as much as before. Therefore, this paper reveals the plasticity through historical study of socks and stockings. The purpose of this research is to analyse the plasticity by image classification of socks and stockings in 1990s on the basis of historical studies, which will be the basic data for developing high value added products. The major plasticity features of socks and stockings are material, technic, formativeness, ornament, color in a word. In 1990s the images of socks and stockings are classified into romantic, sporty, ethnic, ecology, avant- garde image. In 20th century knit and nylon became common and the part of the total fashion, completing the whole fashion.

This study identifies methods to design patterns for jeans that are suitable for women in their twenties. Five patterns suggested by previous researchers were used to draw the same size of jeans (waist 67 and hip 91). The author compared and analyzed the measurements and shapes of the patterns, ranging from waist to crotch. Samples were produced based on these patterns and then tests were conducted to observe the dynamic functions and exteriors of the samples. The dynamic functions observed in this study include walking, ascending stairs, descending stairs and sitting on chairs. The results of the current study are as follow. The best evaluated pattern in terms of exteriors is the one where the hips and thighs are tightest compared to other patterns and where the back part is wider than the front part. This pattern also received high evaluations in dynamic functions due to comfort when walking. Regarding ascending or descending stairs, the tests found that all its parts (except the front crotch) are more comfortable than those of any other patterns. All these results show that a comfortable fit and easy movement is possible when the crotch width of the back is broader than the hip width so that the hips are comfortably supported.

Purpose This study was performed to evaluate the stability of dual thread implant using resonance frequency analysis in human. Materials and methods Fifty-five patients(32 males and 23 females) with a mean age of 50 years and 1 month who were treated during March, 2005 to July, 2007 in Pusan National University hospital. Totally 145 dual thread Implants were installed and initial stability was measured by Osstell $Mentor^{TM}$. After 3-6 Months, secondary stability was measured at the time of second surgery or before prosthetic treatment. Results At the time of 1st surgery, average ISQ value was $75.12{\pm}12.06$. Only 1 implant was failed during the healing period. Before prosthetic treatment, ISQ values were measured and its mean value was $80.94{\pm}6.12$. Conclusion These results suggest that the increased stability of the implant verifies the clinical relevance of double thread implant.

The purpose of this study was to compare time use pattern of Korean working couples with those of Japanese counterparts. The data for240 Korean couples living in Seoul and 162 Japanese couples living in Tokyo were collected using structured questionnaire and time diary. The time use patterns of couples were analyzed according to employed status of wives. The results were as follows. The similar time use patterns were found between couples of two country. However the amount of time allocated for daily activities was found to be somewhat different. The amount of time spent by husbands on paid and house work was found to be different according to their wives employment status. The orean husbands of full-time employed wives and the Japanese husbands of part time employed wives spent the longest time on paid work. The Japanese husbands of full-time employed wives spent much more time on housework than those of Korean counterparts did. The social-cultural time of Korean couples was enerally longer than that of Japanese couples. The Korean couples spent more time on watching TV whereas the Japanese couples used more time doing family activities hobbies and moving for social-cultural activities.

Three occupational safety and health (OSH) activities, one international and two national workshops, were documented as part of OSH activities conducted under the International Labor Organization/Korea Partnership Program in the year 2011-2012. This study aimed to provide information on what the three OSH activities were implemented and how they contributed to the improvement of OSH in Asian countries. The international workshop was useful for the participants to understand a variety of information on OSH as well as participatory action-oriented training (PAOT) approaches at the regional and global levels. The two national workshops were practical for participants to strengthen their knowledge and skills on the PAOT at the enterprise and national levels. The study shows that the three OSH activities contributed to the understanding of the participants on OSH and PAOT, and that the activities promoted the improvement of OSH across countries in Asia.

The purpose of this study was to explore the prevalence of hypertension in Haiti and to describe regional characteristics, and thus to speculate Haitian specific regional risk factors. This is a descriptive and comparative study. Subjects were 145 male/female Haitians, who aged between 30 and 59 and have lived in rural areas, had their hypertension indicators being screened. Data were analyzed with descriptive statistics, t-test and ANOVA. More than four fifth of the subjects (82.8%) showed pre-hypertensive or moderate to severe hypertensive condition. 65.5% of the total had abnormal pulse pressure ($PP{\geq}50$) and 13.8% of the sample showed tachycardia (Heart $Rate{\geq}100$). Female Haitian tended to have higher diastolic blood pressure and faster heart rate than male Haitian. The residents who lived in Part 5-1 area with less accessibility to drinking water tended to have higher systolic and diastolic pressure. Hydration status of Haitians was highly considered as an affecting factor on the distribution of hypertension as evidenced by different level of accessibility to drinking water.

To estimate the thermal effect of the vegetation canopy on the surface sublayer environment numerically, we used the combined model of Pielke's1) single layer model for vegetation and Deardorff's2) Force restore method(FRM) for soil layer. Application of present combined model to three surface conditions, ie., unsaturated bare soil, saturated bare soil and saturated vegetation canopy, showed followings; The diurnal temperature range of saturated vegetation canopy is only 20K, while saturated bare soil and unsaturated bare soil surface are 30K, 35K, respectively. The maximum temperature of vegetation canopy occurs at noon, about 2 hours earlier than that of the non-vegetation cases. The peak latent heat fluxes of vegetation canopy is simulated as a 600Wm-2 at 1300 LST. They have higher values during afternoon than beforenoon. Furthermore, the energy redistribution ratios to latent heat fluxes also increased in the late afternoon. Therefore, oasis effect driving from the vegetation canopy is reinforced during late afternoon compared with the non-vegetated conditions.

The development of information & communication technology in 21st century along with the mass media In 20th century, the influence of state-of-art culture in our society rapidly increased in these days. This state-of-art culture makes the world becomes single-channeled by network, and there is a big change not only in human life but also in concept and understand for art and space. The development of digital paradigm and media technology is exerting a strong influence on the Ubiquitous computing environment that is being drawn great interest. The ubiquitous is concerned as expansion of media art, and the interactive art which is part of media art has the similarity with the ubiquitous computing environment. In this study, the possibility of connection between the territory of ubiquitous environment which is recently focused and has strong interrelation feature, and the territory of interacting will be examined. Furthermore, possibility of new space design work through seeking the possibility of connection between two territories will be estimated.
