SLAP(Superior labrum anterior to posterior) lesion is found in superior labrum injury alone and also combined with extension of the Bankart lesion(anteroinferior labral tear) in recurrent shoulder dislocation patients and rarely accompanied by the posterior Bankart lesion. There have been reports about SLAP lesions associated with various lesions, however, posterior type II SLAP lesion associated with posterior Bankart lesion has been rarely reported. In such a case, there are important technical tips in inserting anchors and suturing during arthroscopic repair. We experienced a rare case of posterior type II SLAP lesion associated with posterior Bankart lesion, occurred not after repetitive throwing(common mechanism) but after trauma in slipping down with the arm stretched during riding a bicycle. The satisfactory result was obtained after arthroscopic repair in this case.

Since conventional image surveillance systems employ methods for video recording and transmission, a huge amount of data is transferred and stored so that those systems are overloaded. However, for capturing and recording the scenes of illegal trash throwing and unpermitted parking, it is sufficient to use a surveillance system using images. In this paper, we propose a surveillance system using images and motion detection sensors. Our system recognizes the occurrence of movement events through changes of sensors, captures still images of the region under surveillance, and stores them into the database at a remote site. The system proposed herein provides a functionality to detect the occurrent of those events more accurately and faster than previous video-based systems, and has an advantage of reducing the amount of data significantly. Also, our system is agent-based, it enables us to add new modules or modify existing modules easily later.

Self-weight consolidation test and soil property of dredged soil at Incheon habour route were analyzed to determine the initial dredging reclamation amount, reclamation depth, and estimating the required time of self-weight consolidation with calculation of the final planned height of dredging reclamation site. The moisture content, void ratio and ratio of volume change with elapsed time after throwing were estimated through Yano's empirical equation. As a result, there was a less variation in elements when fine-grained soil content was low as similarly to the behavior of coefficient of sedimentation-consolidation, Cs and the highest variation was shown at the fine-grained soil content of 50%. The retention ratio according to the fine grained soil content that could reinforce the comprehensive aspect of retention ratio for each particle size presented in the standard of estimate for reclamation construction work was calculated and presented using the calculated ratio of volume change.

Purpose: We compared the results of open and arthroscopic Bankart repair in traumatic recurrent anterior dislocation ,3f the shoulder. Materials and methods: We analysed 7 cases underwent open Bankart repair (group I) and 13 cases underwent arthroscopic Bankart repair (group Ⅱ). The average follow-up period was 68.1 months (51-113 months) in group I and 41.1 months (16~57 months) in group Ⅱ. All patients in group I and Ⅱ were non-athletes. We analyzed statistically objective evaluation, such as the stability of shoulder joint, the range of motion, pain, impaired throwing, Bankart rating system by Rowe and subjective evaluation, visual analog scale (VAS) between two groups. Results: In terms of dominant and non-dominant shoulders, the age at initial episode of dislocation, the elapsed time from injury to surgery, the number of preoperative dislocations associated with susceptibility to apprehension. respectively, there was no statistically significant differences between two groups. In group I the average Rowe's scortls was 84.3 and 3 cases (43%) had excellent results,4 cases (S7cfo), good ones. In group H the average Rowe's scores was 87.3 and 7 cases (54%) had excellent results,6 cases, good ones. There was tendency to show more excellent results in group ll, but there was no statistically significant differences. The average VAS were 90.3 points in group I and 88 points in group Ⅱ, which showed also no statistically significant differences. Conclusion: Open and arthroscopic Bankart repairs had no significant difference and showed also good results in travinatic recurrent anterior dislocation of shoulder.

The purpose of this study was to provide information about kinematic variables of the gliding and delivery motion of Hyung-Keun Lee, a high school shot putter who was ranked 1st at the 2011 National Sports Festivals. Three-Dimensional motion analysis using a system of 4 video cameras at a sampling frequency of 60 Hz was conducted during shot-putting events at the 2011 National Sports Festivals. During the gliding and delivery phase of the player the results showed following characteristics; 1) The gliding technique types of the player appeared to be the short-long technique as the gliding and stance length ratio were $42.3{\pm}3.87$ % and $57.7{\pm}3.87$ %, respectively. In addition, the trajectory of shots during the gliding and delivery phase showed different trajectory patterns with "S-shaped" type of elite players due to the deviation from a central axis of the APSS (athletic-plus shot system). 2) The horizontal velocity of COG made from gliding should maintain the velocity during transition and release phase, but the player showed a small momentum for a gradual decrease of velocity. 3) Therefore, the player requires to adjust an appropriate ratio between gliding and stance length with a strong muscle power at the trunk, throwing arm, and the lower extremity during gliding and delivery phase.

Purpose: The aim of the study was to investigate how adolescents' behavior is correlated with child abuse they experience, and how childrearing attitude of mothers perceived by the adolescents is correlated with child abuse experience by the adolescents. Method: A convenient sampling strategy was used. A total of 160 adolescents participated in this study. Of the 160 responses, 116 were used for final analysis. The data were analyzed using K-YSR program and SPSSWIN. Result: The results were as follows. Mild child abuse experiences reported by the subjects were Throwing the object at me (12.9%, N = 15), Clutching and pushing (12.9%, N = 15), and Slapping on the cheek (14.7%, N = 17)'. Severe child abuse experiences reported by the subjects were Kicking, pounding and biting (10.3%, N = 10), Rod, stick, belt, broom beating using various objects (41.4%, N = 38), and Beating all over the body (6.7%, N = 8). Very severe child abuse experiences reported by the subjects were Burning with cigarette (0.4%, N = 1), Threatening me with objects such as a knife, a hammer, an axe, or a gimlet (0.8%, N = 2). Injuring me with the objects (0.4%, N = 1), and Hospitalized by belting (0.4%, N = 1). In terms of correlations among the main study variables, physical child abuse had significant positive correlations with externalizing problem (r=.271, p=.001) and total behavioral problem (r=.288, p=.002). Physical child abuse also had a significant positive correlation with authoritarian childrearing attitude of mother (r=.363, p=.000). Physical child abuse had significant negative correlations with mothers affectionate childrearing attitude (r=-.191, p=.050) and active participative childrearing attitude (r=-.101, p=.035). Conclusion: Mothers childrearing attitude is a salient factor for preventing child abuse. In addition, child abuse is an important factor for preventing adolescent's behavioral problem.

The purpose of this study was to identify biomechanical characteristics of glide and delivery motion of In-Sung Hwang, player who is a member of the national team among the finalists in the men's shot put at the 2010 National Sports Festivals. Three-Dimensional motion analysis using a system of 3 video cameras at a sampling frequency of 60 Hz was performed for this study. During the glide and delivery phase the results showed following characteristics; 1) The glide type was suitable for the short-long technique, but the trajectory of shot at the glide and delivery phase showed a different trajectory pattern with "S-shaped" type of elite players due to many deviating from central axis of the APSS(athletic-plus shot system). 2) Left knee was more flexed during failed trials compared to successful trials but COG was higher. Therefore, the player showed less stability of COG as he may not get enough breaking force at the left foot. 3) Furthermore, it would be required to have strong muscle power at the trunk, throwing arm, and the lower extremity in order to achieve maintain a low projection angle of the release.

This study is to discuss the content of Posangkimun on the whole and to report the understanding of Seokgok Lee Gyujoon on western civilization. Through the overall analysis of Posangkimun, it is found the following facts: 1. Posangkimun aroused interest of academic circles as it covered theories of western civilization. Most of the introduction to western civilization contained in the book is related to astronomy and geography. Seokgok criticized all the western theories on revolution of the earth, astronomy, continents and oceans on the ground that these theories were not congruous with the teaching of the Oriental sages. 2. Seokgok found the reasons why the West had led the East from 'nationalism' of the West. The nationalism mentioned here were more similar to 'democracy' in modern sense, or rather 'democratism'. What is specially noteworthy is that he did not find the reasons of western advancement from the spiritual issues not from the machine civilization. In this way, Seokgok could avoid the fallacy of throwing away traditional ideas to concentrate in western machine civilization. 3. The content of Posangkimun shows that Seokgok was a person with a very conservative view. Notwithstanding his inclination, he had good knowledge about western theories, most of which were gathered from newspapers and magazines at that time. It means that newspapers and magazines should be treated with more importance when studying Korean intellectuals in late Joseon period or during the time of Japanese forced occupation.

ML's exception handling makes it possible to describe exceptional execution flows conveniently. Sometimes, current implementation of exception handling introduces unnecessary overhead. Our goal is to reduce this overhead by source-level transformation. To this end, we transform source programs into variant of continuation-passing style(CPS), replacing handle and raise expressions by continuation-catching and throwing expressions, respectively. CPS-transforming every expression, however, introduces a new cost. We therefore use an exception analysis to transform expressions selectively: if an expression is statically determined to involve exceptions then it is CPS-transformed; otherwise, it is left in direct style. In this article, we formalize this selective CPS transformation, prove its correctness, and present possible improvement for our transformation.

Most of families in Korea keep some medicines that has been expired or not been used for a long time, and these medicines could be causing environmental or social problems. Currently many people concerned about their health and therefore show a tendency to visit many health facilities. It eventually brings to remain more medication in home The aim of this study is to determine the drug waste minimization and drug disposal in Korean home and provide the proper guideline for them. This study were performed by visiting total randomly selected 140 homes at the Seoul area from July 23rd, 2008 to July 31st, 2008 by questionnaire. This survey comprised total 6 parts and total 22 questions. In results, 77 (55.0%) among 140 families answered to this survey. 89.6% of families keep unused medicine in the home. Most were tablet (66.3%) and syrup (19.2%) dosage type. They usually kept the unused medicine in the room (41.6%) or no certain place. 76.6% families reused the medicine and used for themselves. The reason for reuse is similar symptoms by their decision. The reason for medicine was left over is not following the prescription's direction (31.3%). They mostly dispose the unused medications by throwing into a trash can (71.4%). In conclusion, many families keeps unused medication and it could cause health and environmental problems.
