To compare the treatment effects of back exercise on functional status, spinal mobility, SLR, pain severity, and treatment results satisfaction, and to determine whether spinal exercises during the low back pain reduces recurrent episodes of back pain. 1. Flexion and extension exercise groups did not differ in any outcome over 4weeks. After 1 week. both exercise groups had reduced disability score, a higher proportion returning to work, and fewer subjects with a positive SLR compared with the control group. 2. There was no difference among groups regarding recurrence of low back pain after $6{\sim}12$ months. 3. There was no difference for any outcomes between the flexion or extension groups. However, either exercise was slightly more effective than no exercise when patients with low back pain were treated.

권혁수(Kwon Hyeok Su) 한국문화콘텐츠학회 2014 문화예술콘텐츠 Vol.- No.12·13

본고는 카카오 게임 플랫폼 기반 소셜 네트워크 게임(Social Network Game:이하 SNG)의 지속적인 발전 현황에 주목하여 일반적인 특성을 파악하고, SNG의 다양한 구성 요소 중에서도 콘텐츠와 향유자 사이의 접점을 형성하는 유저 인터페이스(User Interface:이하 UI) 분석을 통해 아케이드 게임의 장르별 UI 특성을 도출하고자 하였다. 먼저, 게임 플랫폼 기반 SNG의 발전 현황 및 특성의 도출 결과를 통하여 카카오 게임 플랫폼 기반 SNG의 UI를 분석하고자 하였다. UI의 구성 요소는 게임의 외적 영역, 게임의 내적 영역, 사회적 교류영역으로 나누어 분석하였다. 외적 영역은 레이아웃 영역, 정보 영역으로 나누어 분석하였고, 내적 영역은 게임의 캐릭터, 게임의 배경, 게임의 정보, 게임의 아이템으로 나누어 분석하였으며, 사회적 교류 영역은 게임 외 교류 영역, 게임 내 교류 영역으로 나누어 분석하였다. 차후 연구에서는 분석 대상의 측면에서는 카카오 게임 플랫폼만이 아닌 여타 모바일 인스턴트 메신저(Mobile Instant Messenger:이하 MIM) 기반 게임 플랫폼과의 비교를 통한 후속 연구가 필요할 것이다. 또한, 연구 범위 측면에서는 본 연구의 방향성을 잇는다면 UI에서 나아가 좀 더 포괄적인 사용자 경험(User eXperience : 이하 UX)에 대한 분석을 통해 사용자의 경험적 요소에 대한 정성적/정량적인 접근으로 범위를 확장할 필요성이 있다. 향후에는 이러한 본 연구의 한계를 극복하고 MIM기반 SNG에 대한 포괄적인 특성을 제시하는 연구가 지속적으로 나오기를 기대해본다. This thesis is basically focused on the widespread characteristics of Kakao game Platform-based Social Network Game(hereinafter referred to as the SNG) considering the current status of its continuous development and try to determine the UI Characteristics of Arcade game through the analysis based on the User Interface(hereinafter referred to as the UI) between the contents and the person who enjoys the game. First of all, This thesis is to define UI of Kakao Game, platform-based SNG through the results, mentioned above, of the development status and features of Platform-based Arcade game. The components of UI are divided into the external field, the internal field and the social exchange field of the game. The external field is divided into the layout filed and the information field. On the other hand, the internal field is divided into the background, the game characters, the information and the items of the game. The social exchange filed is divided into the interaction field between the game and messenger. In the aspects of the analysis for the target, the follow-up study would be required through the comparison of both Kakao game platform and the game platform based on Mobile Instant Messenger(hereinafter refereed to as the MIM). Moreover, the further study is needed to expand the scope of the research related to the inclusive study for UX which is advanced model of the limited UI study. It s about the time the qualitative/quantitative approach would be required in the empirical factors of user. Thus, I expect that not only will the limitations in study be overcome but also better study results will come out with continuous study which suggests the comprehensive characteristics of MIM based SNG.

Markolf and Morris suggests that the deranged disk and torn annulus have an exellent recovery ability from the position of spine extension, where the posterior annulus is not under stress and the gel can move anterioly. McKenzie explains side gliding as a combination of rotation and side bending, his clinical studies indicate that side-gliding can gel laterally. In conclusion, the prone unilateral traction on the opposite side from the patient's pain along with the other treatment appered to have helped reduce those patient's pain. The method of treatment described in this report is suggested for Korean physical therapists who treat patients suspected of posterolateral herniated nucleus pulposus.

This research have been made to define how the IADL (Instrumental Activity of Daily Living) performance and the subjective health index of the Aged are affected by their residential circumstance, gender and age, and how deeply these two factors are related and interact. For the period of June 1 to July 31, 2000, we had conducted a questionnaire and direct interview with 693 persons over age sixty-five (65) in Daejon and in other adjacent area, grouping into three different residential types The Aged living at home, The Aged living at welfare facilities and The Aged living alone, and studied on how the IADL performance and the subjective health index of the Aged are influenced and interact as per their characteristics, daily activity and mentality. We had analyzed all the data obtained through this research by the method of : - analysis of frequency as per specific factors by SPSS 10.0/PC+, - x^2 test, - t - test, - ANOVA, - multiple regression analysis by factors. The research concludes followings : a. It appears that the three (3) factors such as gender, age and residential circumstance of the Aged deeply affect the IADL performance and subjective health index of the Aged. (p<0.01) b. With regard to IADL performance of the Aged by the gender, it was analyzed that the female-Aged gains 23.8 point on average, which shows the performance of the female-Aged is less independent. (p<0.01). In addition, it was also found that the IADL performance is becoming less and less independent following their age increasing. In analyzing IADL performance by the residential type, it appears that the Aged living at welfare facilities gains the lowest 21.5 points and is least independent. It was also found that the Aged living at welfare facilities need some assistances from others for their performing IADL. (20-24 point) (p<0.001) c. With regard to the subjective health index of the all-Aged participated in this research, the analysis indicates 8.8 point and this is considered as a point of general standard (7-10 point). In analyzing this index by the gender, the female-Aged gains only 8.6 point which explains a lot of female-Aged consider they are not really healthy. (p<0.001) In analyzing this index by the residential type, the Aged living at welfare facilities and the Aged living alone gain the comparatively lower point, - respectively 8.4 point for the Aged living at welfare facilities and 8.8 point for the Aged living alone. The Aged living at these two residential types express they are obviously in a bad situation of health. (p<0.001) d. With regard to the factors affecting the IADL performance and the subjective health index of the Aged, it was analyzed that the IADL performance can largely be affected by the factors such as depression, frequency of going-out and age rising, and that the subject health index can also deeply be affected by depression, pain and by how much they are satisfied with their current living conditions. e. It was analyzed that the interacting between the IADL performance and the subjective health index is not that strong but even weak. As a result, we were able to conclude that the IADL performances is less independent in case of the female-Aged, the Aged living at welfare facilities, and following the age rising. As for the subjective health state the Aged themselves are aware of, we concluded that the female-Aged, the Aged living at welfare facilities and the Aged living alone, are more critical about their health. From this research, we were able to realize that, when the OMT (Orthopedic Manual Therapy) needed, the physical therapists are really required to have a correct and cautious understanding of the situation in which the aged persons are, and take care of them with more concerns and more improved treatment.

The PT program provides relief to most patients with symptom of TOS. So the purpose of our study is to evaluate a effects of PT program in patients with TOS. PT program included orthopaedic manual therapy with the aim of rrestoring the function of the upper thoracic aper-ture is to be recommended, and long-term following is advisable. 1. Mean treatment duration was over an 11.4 day(range 4~24). 2. At the follow-up evaluation, 88.1% of the patients were satisfied with the effects of their therapy. 3. 73% of the patients returened to work after PT and 88% of the patients carrried through the recommendations given at discharge during follow up. 4. Normalized grip strength and Tinel' sign predicted patient satisfaction(p<.001) and re-turn to work(p<.001). 5. Return to work was more often successful if the work was sedentary rather than heavy (p<.05).
