  • The purpose of this study is to make an empirical analysis on the factors affecting the intention for the continuous use of the BSC system, which has been recently spread in the public sector. Because the object of acceptance is the performance management system based on BSC (Balanced Scorecard) implemented in the form of information systems, this study proposes a research model by applying TAM (Technology Acceptance Model). Independent variables are factors affecting the acceptance of BSC system such as training, communication, IS support, CEO support and personal innovativeness, and we examine their effects on the dependent variable, namely, intention on continuous use via mediating variables: perceived usefulness and perceived ease of use. A questionnaire survey was conducted with public institutions(firms) that had introduced and were operating the BSC system; 264 valid questionnaires are adopted. Collected data are analyzed using SPSS 16.0 and AMOS 7.0. Results of reliability test show that all analyzed data are reliable. In validity test, one item regarding communication was excluded; 9 latent variables and 34 observed variables are used in the final analysis. Based on the results of the hypothesis test through path analysis using a structural equation model, 10 out of 16 hypotheses are accepted. Factors affecting perceived usefulness are training and IS(Information System) support. The analysis results indicate that perceived ease of use is mainly affected by IS support, CEO support, and personal innovativeness among the factors related to the acceptance of the BSC system. This suggests that, contrary to the expectation that the BSC system may be used without difficulty, the management's active support is required in order to attain expected improvement in productivity and work efficiency. This was also pointed out in case studies on the construction of the BSC system in public sectors. On the other hand, perceived ease of use is found to affect perceived usefulness. This supports the results of previous researches on TAM. Perceived ease of use and perceived usefulness are found to affect the attitude towards the use of the system. The intention on continuous use is affected more by perceived usefulness than by the attitude towards the use of system. This result supports the results of previous researches on TAM, showing that the BSC system is utilized substantially in worksites. This study is considered meaningful in that it was actually performed on users at public institutions(firms) that had introduced the BSC system and that it empirically tested hypotheses on the acceptance of the BSC system by applying TAM to the research model.

  • An outbreak of dermatosis occurred at a machine manufacture factory in Kyongju on Aug 1995. Authors conducted a questionnaire ,survey among 92 workers in the factory and a dermatologist examined their skin lesions. Authors also collected moths and identified them. The results are as follows; 1. Forty-two cases of dermatosis were identified with attack rate of 45.7%. Attack rate was not different by company, age, sex, educational level and duration of employment. Attack rate was 47.8% among productive workers, 25.0% among clerical workers and 100.0 % among patrolmen. 2. Two cases among 42 dermatosis cases and three subjects among 50 non-cases had a history of same dermatosis last year. Four of dermatosis cases had a history of dermatosis among their family members. 3. Skin lesions of the cases were scattered or grouped rice-sized erythematous papules or vesicles. Duration of dermatosis from the onset to the time of survey was from one day to more than 30 days. The most frequent site of skin lesion was the arms(81.0 %), and it was also observed at the neck(47.6 %), abdomen(45.2 %), chest(42.9 %), legs(38.1 %) and back(35.7 %). Skin lesion was aggravated with sweating(31.0 %), after shower(16.7 %) and with scratching(11.9 %). 4. Moths were collected and identified as Euproctis subflava (Bremer). Many poisonous stings were observed on their wngs which is harmful to human. 5. Contact with moths' wing droppings to two authors on thier forearms for provocation resulted in severe immediate pain followed by prolonged pruritus. Erythematous macules quickly appeared and succeeded by firm wheal-like red papules. Authors thought that the outbreak of dermatosis was brought about by Euproctis subflava (Bremer). Further studies on the factors contributing to the prosperity of the moths in this area are needed.

  • 인화점은 가연성 액체 용액의 폭발과 화재의 위험성을 결정하는 가장 중요한 성질 중 하나이다. 본 연구에서는 2개의 가연성 이성분계 혼합물인 n-pentanol + n-propanol계 및 n-pentanol + n-heptanol계의 인화점을 Seta flash 밀폐식 장치를 사용하여 측정하였다. 인화점은 라울의 법칙을 이용한 방법과 다중회귀분석법에 의해 계산되었다. 그리고 그 결과를 측정값과 비교하였다. 라울의 법칙에 의해 계산된 결과의 절대평균오차는 n-pentanol + n-propanol계인 경우 $1.3^{\circ}C$이며 npentanol + n-heptanol계인 경우 $1.3^{\circ}C$이었다. 다중회귀분석법에 의해 계산된 결과의 절대평균오차는 n-pentanol + npropanol계인 경우 $0.4^{\circ}C$이며 n-pentanol + n-heptanol계인 경우 $0.3^{\circ}C$이었다. 절대평균오차에서 알 수 있듯이 다중회귀 분석법에 의한 계산값이 라울의 법칙에 의한 계산값에 비해 측정값을 잘 모사하였다.

  • Background: Ovarian cancer is ranked as the fifth most common cause of cancer death in women. In Malaysia, it is the fourth most common cancer in females. CA125 has been the tumor marker of choice in ovarian cancer but its diagnostic specificity in early stages is only 50%. Hence, there is a critical need to identify an alternative tumor marker that is capable of detecting detect ovarian cancer at an early stage. HE4 is a new tumor marker proposed for the early diagnosis of ovarian cancer and disease recurrence. Currently, none of the normal ranges of HE4 quoted in the literature are based on data for a multiethnic Asian population. Therefore, the aim of this study was to determine reference intervals for HE4 in an Asian population presenting in University Malaya Medical Centre, a tertiary reference hospital. Materials and Methods: 300 healthy women were recruited comprising 150 premenopausal and 150 postmenopausal women, aged from 20-76 years. All women were subjected to a pelvic ultrasonograph and were confirmed to be free from ovarian pathology on recruitment. Serum HE4 levels were determined by chemiluminescent microparticle immunoassay (CMIA, Abbott Architect). The reference intervals were determined following CLSI guidelines (C28-A2) using a non-parametric method. Results: The upper limits of the $95^{th}$ percentile reference interval (90%CI) for all the women collectively were 64.6 pmol/L, and 58.4 pmol/L for premenopausal) and 69.0 pmol/L for postmenopausal. The concentration of HE4 was noted to increase with age especially in women who were more than 50 years old. We also noted that our proposed reference limit was lower compared to the level given by manufacturer Abbott Architect HE4 kit insert (58.4 vs 70 pmol/L for premenopausal group and 69.0 vs 140 pmol/L in the postmenopausal group). The study also showed a significant difference in HE4 concentrations between ethnic groups (Malays and Indians). The levels of HE4 in Indians appeared higher than in Malays (p<0.05), while no significant differences were noted between the Malays and Chinese ethnic groups. Conclusions: More data are needed to establish a reference interval that will better represent the multiethnic Malaysian population. Probably a larger sampling size of equal representation of the Malay, Chinese, Indians as well as the other native ethnic communities will give us a greater confidence on whether genetics plays a role in reference interval determination.

  • The aim of this paper was to prove that if the risk level in combined tasks was improved through evaluation of postural load of liquid weight measurement process, the workload level and ratio of exposure time would be changed, and the time of process would be seen concurrently. Background: According to results of epidemiological studies conducted by Korea Occupational Safety & Health Agency, 122 musculoskeletal disorders occurred during 1992 to 2008, in which manufacturing industry covers 96(78.7%) of total. However, this is an insufficient level and only occupies 39% based on the South Korea's manufacturing standard industrial classification(246 industries). Method: Firstly, the number of batches weighed on one day(460min) was investigated based on the work performed and Weight measured weekly. VCR recording was taken based on the level of liquid ingredients prescribed for 1batch using the Camcorder. After dividing a 356 sec video into 1 sec using the screen capture function in Gom player, the job classification was performed by analyzing the change of working postures, which revealed 148 working postures. Time measurement was decided by time of the postures was being maintained. Then, the REBA analysis was performed for the working postures. The ratio of Exposure time was calculated based on the measurement time and REBA Score. In addition, the recommendations were designed and implementation was carried out for the working postures with REBA Score higher than 3. Finally, after the intervention, REBA measurement, time measurement, and ratio of exposure time were calculated for the comparison of works before and after improvement. Results: The number of work elements was decreased by 30.4% from 148 to 103 after improvement. The results of time measurement showed that the time was reduced by 46.3% from 356 sec to 191 sec. And the ratio of exposure time was also improved by 52.1% from 0% to 52.1% after improvement. Conclusion: The reduction of time was found to improve the productivity of management. Furthermore, because the reduction of ratio of exposure time and the improvement of workload level are the improvement of discomfort, it would contribute to the improvement of the worker's psychological working posture. Application: These results would contribute to musculoskeletal disease prevention and management performance. Further studies for other industries would be needed based on this case study.
