Purpose : In this study, rectus abdominis relaxation intervention was administered to office workers who were experiencing low back pain due to sitting for extended periods of time in an incorrect posture. This study aimed to develop an effective treatment program for individuals who experience low back pain. This was done by verifying changes using the Korean Oswestry Disability Index (K-ODI) and considering kyphosis. Both factors are related to low back pain. Methods : This study included 39 office workers with low back pain. The participants were randomly assigned to three groups. 1) The functional massage and self-stretching (FAS) group (n=14). 2) The diaphragmatic breathing and self-stretching (DAS) group (n=13). 3) The self-stretching (S) group (n=12). All groups applied the intervention for 30 minutes a day, thrice a week for four weeks. All participants were evaluated using the K-ODI and thoracic kyphosis measurements before and after the intervention. Results : The findings of this study are as follows. All three groups had improved K-ODI scores after the intervention. The FAS and DAS groups showed a greater effect than the S group. However, there was no difference in effect between the FAS and DAS groups. Kyphosis was not improved in any of groups after the intervention, and there was no difference between the three groups. Conclusion : This study showed that the FAS, DAS, and S programs were effective relaxation interventions that improved the K-ODI for office workers with low back pain. The FAS and DAS programs were more effective than the S program. Therefore, it is recommended to combine relaxation and stretching of the rectus abdominis muscle for office workers who experience low back pain. Clinically, a relaxation intervention that is most appropriate for the patient, depending on his or her condition, should be.

Objective: To compare the effects of lumbar dysfunction and balance when office workers with chronic back pain performed the abdominal drawing-in maneuver. Methods: A total of 16 office workers with chronic low back pain were included in this study. The participants were randomly divided into two groups: the general and abdominal drawing-in maneuver groups. The intervention was applied for 6 weeks, 3 times a week, 70 min per day. Participants in the general exercise group(n=8) performed the general physical therapy and lumbar flexibility exercise, whereas those in the abdominal drawing-in maneuver group(n=8) performed the general physical therapy and lumbar stabilization exercise using abdominal drawing-in maneuver(3 times/week for 6 weeks). All tests, were the Korean Oswestry disability index (KODI) and balance ability, were completed pre and post-intervention. Results: Significant improvements in the KODI and balance ability test were observed in the abdominal drawing-in exercise group (p<.05), whereas no significant changes (p>.05) were observed in the general exercise group. Conclusion: This study revealed that abdominal drawing-in maneuver can effectively improve the lumbar dysfunction and balance ability of office workers with chronic back pain.

Background: Low back pain (LBP) is a major problem for office workers. Individuals adopting poor postures during prolonged sitting have a considerably increased risk of experiencing LBP. This study aimed to investigate seat pressure distribution characteristics, i.e., average pressure, peak pressure ratio, frequency of postural shift, and body perceived discomfort (BPD), during 1 hour of sitting among office workers with and without chronic LBP. Methods: Forty-six participants (chronic LBP = 23, control = 23) typed a standardized text passage at a computer work station for an hour. A seat pressure mat device was used to collect the seat pressure distribution data. Body discomfort was assessed using the Body Perceived Discomfort scale. Results: Office workers with chronic LBP sat significantly more asymmetrically than their healthy counterparts. During 1-hour sitting, all workers appeared to assume slumped sitting postures after 20 minutes of sitting. Healthy workers had significantly more frequent postural shifts than chronic LBP workers during prolonged sitting. Conclusion: Different sitting characteristics between healthy and chronic LBP participants during 1 hour of sitting were found, including symmetry of sitting posture and frequency of postural shift. Further research should examine the roles of these sitting characteristics on the development of LBP.

Objective: In clinical practice, there are a lot of exercise to reduce body weight or reduce the amount of body fat in order to solve back pain. However, many studies have contradicted the relationship between back pain and weight or body fat mass. The purpose of this study was to investigate the relationship between fat mass, body mass index and low back pain of office worker. Design: Crossed-sectional study Methods: Among the white-collar workers diagnosed with non-specific back pain by doctors, subjects who were not included in the exclusion criteria were selected to measure the subject's body fat mass, body mass index, pain intensity, and disability index due to back pain. The NPRS was used for the intensity of back pain of office workers, and the ODI was used for the degree of disability due to back pain. A body composition analyzer was used to measure the body fat mass and body mass index of white-collar workers. Results: There was no significant difference between the two groups in the comparison between the normal group and the excessive group according to the criteria of fat mass and body mass index. In the correlation analysis of fat mass, body mass index, pain intensity, and disability index, it was found that there was a significant correlation between fat mass and body mass index. However, neither fat mass nor body mass index had a significant correlation with pain intensity and disability index. Conclusions: The fat mass and body mass index of office worker do not affect low back pain.

Gains promised by the introduction of e-commerce back-office systems are not easily realized due to poor technology acceptance, especially in developing countries. This study aims to analyze factors which affect information technology acceptance in developing countries. A research model based on TAM is proposed, and it is empirically tested for the hypotheses of factors which affect the acceptance behavior. The result shows that antecedents such as user training influence the technology acceptance in different ways. This study may help accelerate the adoption of back-office systems in developing countries.

사적 제439호인 강원감영은 1395년 원주에 처음 설치된 이래 1895년 23부제의 실시로 폐지되기까지 500년 동안 존속하였다. 강원감영은 관찰사의 겸목제(兼牧制) 시행으로 17세기 이후 본격적 영건이 시작되어 폐지 직전까지 약 50동 670칸 규모로 존속되었다. 일제강점기와 한국전쟁을 겪는 과정에서 대부분의 전각이 훼철되어 2005년 시설 일부를 수리 복원하였고, 현재는 (구)원주우체국 철거 후 감영 후원(後園)에 해당되는 시설을 복원 중에 있다. 강원감영 후원은 일제강점기 일본군 원주수비대 운동장이 조성되면서 전부 없어졌다. 후원 조성을 위한 발굴조사 결과 연못 일부와 건물지가 확인되긴 했으나, 그 전모를 밝히기에는 유구의 교란과 훼손이 심하였다. 그러나 문헌과 그림 등을 통해 후원 전각들을 고찰해본 결과 연못 안에는 봉래각(蓬萊閣) 영주사(瀛洲?:관풍각) 채약오(採藥塢) 조오정(釣鰲亭) 홍교가 건립되어 있었음을 알 수 있었다. 그리고 연못 밖에는 환선정(喚仙亭)과 방장대(方丈臺)가 건립되어 있었다. 후원 전각의 조성경위와 명칭을 살펴보면 모두 신선과 관련되어 있다. 연못 안에는 전설의 신선세계인 삼신산(三神山)을 의미하는 삼도(三島)를 만들고, 그 위에 전각을 지었다. 봉래각을 시작으로 후원에 건립되는 전각들에 영주 방장이라는 이름을 붙이고, 나머지 전각들에도 선가(仙家)의 이름을 부여했다. 후원뿐 아니라 그 주변의 전각들에도 신선과 관련된 이름을 붙였다. '봉래산'인 금강산을 관할했던 강원감영 후원에 이와 걸맞는 신선세계를 조영하였던 것이다. 강원도관찰사들은 여가에 수시로 후원에 나가 신선이 되어 탈속하는 풍류를 즐겼고, '봉래주인', 즉 신선세계의 주인이라 자처하였다. 강원감영은 금강산이 소재해 있던 강원도의 특징이 잘 반영된 신선세계가 구현되어 있었다는 매우 독특한 역사적 의미를 내포하고 있는 것이다.

All chairs are uncomfortable in the long run, but some chairs become uncomfortable more rapidly than others, and in any particular chair, some people will be more uncomfortable than others. Comfort will depend upon the interaction of chair characteristics, user characteristics, and task characteristics. In this study, we intend to design the comfortable office chair by investigating the anthropometric and biomechanical aspects for Korean. Therefore, we determine the design dimensions using the analysis of anthropometric data. With these dimensions, we design the chair mechanism of which backrest reclines with increasing chair pan declination. This mechanism allows the back to get adequate support at the correct level for any backrest declination. Also, the lumbar support in the backrest descends with increasing backrest reclining. By using this chair, a considerably better sitting posture can be obtained, and uncomfortable feeling and back pain may be prevented.

Objective: The purposes of this study are to investigate ergonomic problems and to propose their improving measures in office environment of big general hospitals. Background: Office tasks have varying risk factors of work-related musculoskeletal disorders (WMSDs). The first symptom resulted from the office work was recognized as an occupational disease in Korea in 1986. Although the symptoms have increased since its first recognition, there has been few study on the effect of office work environment settings. Method: First, the author took pictures of working scenes performed in three big university hospitals. Next, the pictures were analyzed in view point of ergonomics. Based on the analysis, their improving measures were proposed for reducing work stress. Results: The results showed that most physical office environment settings such as dimensions of tables/desks and chairs, leg room, thigh, knee and foot clearances, and chairs used did not satisfy the ergonomically recommended design guidelines. In addition, some clerks placed personal belongings under their desks, put monitors in high position and did not lean against the backrest of chairs in seated tasks, which resulted in poor working postures of leg, back, neck etc. It is recommended that the hospital management should provide their clerks with ergonomically designed office furniture and continuously perform ergonomics training program for raising clerks' recognition for office ergonomics. Conclusion: Most office environment settings investigated in this study were not in good condition in view point of ergonomic design for the settings. Application: It would be useful as basic data for establishing ergonomically good office environment in hospitals.
