The objectives of this study were to develope slacks basic block to be used for improving the attactive silhouette and bodily fitness in ready-to-wear and educational patterns. The subjects were from 20 to 24 years old and twenty six body measurements were taken on the National Anthropometric Survey of Korea in 1977. The women in 20's think ideal body shapes are high stature, long legs, slander waist, hip, abdomen, thigh, ankle and light weight. And so it needs to be studied to studied to make slacks pattern which show slander girth and long length. The study was carried out by the following procedures. 1. Through the comparative investigation on the conventional slacks patterns of System M. Muller & Sohn, Secolli, 文化's in Japan, and Won-ja Rim's and the clothing experiment, the characteristics of every four patterns were found. 2. According to the center back slant, reflecting the change of waist circumference, thigh circumference, back crotch length, and the new suitable slacks pattern was achieved. 3. The sensory evaluation for appearance and comfort was applied to evaluate the new slacks pattern by comparing with the conventional slacks pattern. From the result of the sensory evaluation, it was found that the new slacks pattern was more suitable for appearance. 4. The new slacks pattern for women in their 20's were developed as follows ; The waist line came down 2 ㎝, the waist circumference was plus 2㎝ than originally, and the back hip circumference was larger 1 ㎝ than the front hip, the slacks length was created stature/8×4.9, the knee length was stature/8×2.7. The center back crotch length was interspaced 1∼1.5㎝ at the center front, and was at right angle the point which was raised 5㎝ at the side front. This size is not the absolute size but it helps to make the surplus on any other ready-made slacks for women.

Let M be the maximal ideal space of the Banach algebra $H^{\infty}$ of bounded analytic functions on the open unit disc $\triangle$. For a positive singular measure ${\mu}\;on\;{\partial\triangle},\;let\;{L_{+}}^1(\mu)$ be the set of measures v with $0\;{\leq}\;{\nu}\;{\ll}\;{\mu}\;and\;{{\psi}_{\nu}}$ the associated singular inner functions. Let $R(\mu)\;and\;R_0(\mu)$ be the union sets of $\{$\mid$\psiv$\mid$\;<\;1\}\;and\;\{$\mid${\psi}_{\nu}$\mid$\;<\;0\}\;in\;M\;{\setminus}\;{\triangle},\;{\nu}\;\in\;{L_{+}}^1(\mu)$, respectively. It is proved that if $S(\mu)\;=\;{\partial\triangle}$, where $S(\mu)$ is the closed support set of $\mu$, then $R(\mu)\;=\;R0(\mu)\;=\;M{\setminus}({\triangle}\;{\cup}\;M(L^{\infty}(\partial\triangle)))$ is generated by $H^{\infty}\;and\;\overline{\psi_{\nu}},\;{\nu}\;{\in}\;{L_1}^{+}(\mu)$. It is proved that %d{\theta}(S(\mu))\;=\;0$ if and only if there exists as Blaschke product b with zeros $\{Zn\}_n$ such that $R(\mu)\;{\subset}\;{$\mid$b$\mid$\;<\;1}\;and\;S(\mu)$ coincides with the set of cluster points of $\{Zn\}_n$. While, we proved that $\mu$ is a sum of finitely many point measure such that $R(\mu)\;{\subset}\;\{$\mid${\psi}_{\lambda}$\mid$\;<\;1}\;and\;S(\lambda)\;=\;S(\mu)$. Also it is studied conditions on \mu for which $R(\mu)\;=\;R0(\mu)$.

Deokjin Park in Jeonju City was the site of a pond during the Koryo Period. Although Jeonju City has developed rapidly in modem times, Deokjin Pond was preserved and was developed into a park It can be theorized that Deokjin Pond's latent character has made it possible for it to adapt to the changes it has undergone throgh the years. In this study, the placeness of Deokjin Park is determined by examining its role in the adaptation process. Placeness can be determined by examining the objective character of a certain environment and the subjective experience related to it. For this paper, documents about the history of Deokjin Park were examined so that the facts related to it could be established. In addition, a number of Jeonju citizens were asked about their memories of Deokjin Park since memories reveal people's subjective experiences. The results of this study can be summarized as follows. Deokjin Pond is an ideal space for Feng Shui. It is a holy place because the tomb of the founder of the Chosun Dynasty is close to it. In addition, it has scenic value as it is part of the Jeonju Palkyoung (eight sceneries). To this day, we can see people washing their hair in the pond, proof that Deokjin Pond is still the subject of folk beliefs. When Korea was under Japanese rule, Deokjin Pond became Deokjin Park because of its ideal location, scenic value, and grand possibilities as an amusement center. Over the years, though its scenic value decreased after the death of its pine trees. Jeonju City, however, was able to revive the park's charm though a series of renovation projects and through the addition of several facilities. Deokjin Park is now surrounded by many cultural buildings. The significance of Deokjin Park can be expected to evolve with these changes. This study helps to predict the future of Deokjin Park and to elucidate the importance of landscape architecture from the point of view of an "evolving place."

Objectives : In this study, 233 dental hygiene students in Seoul and Gyeonggi areas were surveyed in order to provide the basic data for more effective clinical practice by investigating the stress they experience during the clinical practice and how they cope with stress; Methods : 5 areas in stress factors as environmental factor, interpersonal factor, role and activity, ideal and value, and the amount of BEPSI and 4 areas in their coping methods as problem-oriented, social support, emotion-oriented, and wishful thinking were measured by Liker 5-point scale. Results : 1. The satisfaction level of subjects on their major was the highest as 'generally satisfied (50.6%),' and their satisfaction level of clinical practice was also the highest as 'generally satisfied (32.6%).' 2. The clinical practice stress was 2.76 points on average, and their stress factors were ideal and value (3.18), environmental factor (2.98), role and activity (2,70), the amount of BEPSI (2.55), and interpersonal factor (2.37). And the way how they cope with stress were 3.29 points on average, wishful thinking (3.71), social support (3.36), problem-oriented (3.13), and emotion-oriented (2.95). 3. The clinical practice stress according to clinical training institutions showed significant differences: university dental hospitals and general hospitals (2.83), dental clinics (2.65), and dental hospitals (2.63). 4. The clinical practice stress showed a negative correlation between the satisfaction level of major and the satisfaction level of clinical practice (p<0.01), and the more satisfaction they had in their major and clinical practice, the less stress during the clinical practice. 5. In the correlation between each subordinate factor of the stress in clinical practice and how to cope with it, interpersonal factor and emotion-oriented factor, the amount of BEPSI and wishful thinking showed a positive correlation (p<0.05). Conclusions : In this study, it is necessary to develop clinical practice program that is to increase satisfaction and provide motivation in order to reduce the stress during clinical training.

Objectives: The purpose of this study was to suggest an effective instruction method for dental hygiene students by determining the degree of importance and satisfaction that they attach to the courses. Methods: Data obtained from a survey that was conducted on 654 dental hygiene students were analyzed. Statistical Package for the Social Sciences version 23.0 was used for the statistical analysis. A paired t-test was conducted to detect the differences between the degree of importance that the respondents attached to the courses and the degree of satisfaction they achieved. A comparative analysis of the two was performed using the IPA analysis. Results: Regarding the items, the respondents found the environment most important, followed by the content, method, perspective, and assessment. Regarding satisfaction, they were most satisfied with the environment, followed by the perspective, method, content, and assessment. Regarding the importance of ideal teaching, the respondents gave the highest priority to 'a class in which the core content is summarized, emphasized, and explained.' The satisfaction was the highest toward 'PowerPoint-based classes in which the core content is well-organized.' Based on the results of the IPA analysis, the respondents regarded 16 items as requiring maintenance and continuous efforts, 12 items as low priority, and 4 items as requiring excessive efforts and timely improvement. Conclusions: An ideal class requires the instructor to utilize various teaching methods that would enable the students to comprehend the detailed teaching content and elicit active interaction and feedback from the students through easy-to-understand lectures that are appropriate for students.

Ecological network can solve the ecological problems such as habitat cutting and fragmentation that are resulted from urbanization. Recently, rooftop biotope construction has been appeared as a usefull method for ecological networking in urban area. The objective of this study is to seek the possibility of rooftop greening introduction as well as to select target species for rooftop greening construction from the urban ecological network point of view. In order to select target species, we monitored two adjacent rooftop greening sites, where we found 22 species of birds and insects and 33 species of plants. We set criteria to select target species through documents research, and gave marks species according to the criteria with the help of specialists. We divided the target species into 5 groups on the basis of the 12 selecting criteria. In those two monitored rooftop greening sites, we did not find any species belong to group A, which is the best target species, but we found species belong to the other groups. Orthetrum albistylum, Sympetrum dawinianum belong to group B, which is the priority target species, 7 species besides Passer montanus, Coccinella axyridis, Agrionidae to group C, which is the possible target species, 6 species besides Atractomorpha lata to group D, which is the potential target species, and the others were found to be inadequate to the target species. We found Orthetrum albistylum, Sympetrum dawi-nianum to be the best appropriate target species in the two sites. According to the result of this study, the method of ecological network construction from the dra-gonfly habitat network point of view through the construction of rooftop habitat is ideal for Orthetrum albistylum, and Sympetrum dawinianum. For successful urban ecological network construction, selection criteria and construction techniqes & methods for rooftop habitat should be developed through future research.

Tetanus is a specific infectious disease, which is often associated with catastrophic events such as earthquakes, traumas, and war wounds. The obligate anaerobe Clostridium tetani is the pathogen that causes tetanus. Once the infection of tetanus progresses to an advanced stage within the wounds of limbs, the rates of amputation and mortality increase manifold. Therefore, it is necessary to devise a rapid and sensitive point-of-care detection method for C. tetani so as to ensure an early diagnosis and clinical treatment of tetanus. In this study, we developed a detection method for C. tetani using loop-mediated isothermal amplification (LAMP) assay, wherein the C. tetani tetanus toxin gene was used as the target gene. The method was highly specific and sensitive, with a detection limit of 10 colony forming units (CFU)/ml, and allowed quantitative analysis. While detecting C. tetani in clinical samples, it was found that the LAMP results completely agreed with those of the traditional API 20A anaerobic bacteria identification test. As compared with the traditional API test and PCR assay, LAMP detection of C. tetani is simple and rapid, and the results can be identified through naked-eye observation. Therefore, it is an ideal and rapid point-of-care testing method for tetanus.

Purpose: The mastoid region is ideal for studying sexual dimorphism due to its anatomical position at the base of the skull. This study aimed to determine sex in the Iranian population based on measurements of the mastoid process using different data mining algorithms. Materials and Methods: This retrospective study was conducted on 190 3-dimensional cone-beam computed tomographic (CBCT) images of 105 women and 85 men between the ages of 18 and 70 years. On each CBCT scan, the following 9 landmarks were measured: the distance between the porion and the mastoidale; the mastoid length, height, and width; the distance between the mastoidale and the mastoid incision; the intermastoid distance (IMD); the distance between the lowest point of the mastoid triangle and the most prominent convex surface of the mastoid (MF); the distance between the most prominent convex mastoid point (IMSLD); and the intersecting angle drawn from the most prominent right and left mastoid point (MMCA). Several predictive models were constructed and their accuracy was compared using cross-validation. Results: The results of the t-test revealed a statistically significant difference between the sexes in all variables except MF and MMCA. The random forest model, with an accuracy of 97.0%, had the best performance in predicting sex. The IMSLD and IMD made the largest contributions to predicting sex, while the MMCA variable had the least significant role. Conclusion: These results show the possibility of developing an accurate tool using data mining algorithms for sex determination in the forensic framework.
