A new E_n score of the proficiency test (PT) is formulated; it is applicable when a correlation exists between the reference and participant's values. Based on the uncertainty propagation rule given in ISO/IEC Guide 98-3 (GUM:1995), the E_n score covering the correlation case is newly developed for the PT. The new E_n score will be applied in a future PT organized by the Korea Research Institute of Standards and Science (KRISS) dosimetry team. The new E_n score will enhance measurement traceability and contribute to improving the quality management system of participants in the KRISS PT by avoiding performance underestimation.

The purpose of the study was to examine alternating motion rate and its variability in children with childhood apraxia of speech (CAS) compared to typically developing children. Six children with CAS aged 9-12 years old and 10 children who were age-matched participated in the study. This study measured tokens per second and variabilities of the rates during the production of /$p^*$ a/, /$t^*$ a/, and /$k^*$ a/. For variability measures of the rates, each participant was asked to repeat speech tasks three times and the average value of the rates and its standard deviation were obtained. The results revealed that the CAS group showed slower rate only at /$k^*$ a/ than the control group. The CAS group exhibited greater variability of AMR at all the tasks than the control group. The results suggested that variability of AMR might be a more distinctive speech feature to children with CAS than the rate of the speech task.

Quality Control programs for industrial hygiene laboratory have successfully been operated since the 1st round was initiated in April 1992. Three rounds have been completed. Overall analytical performance of participants was improved through a subsquent round. The first round had a large variation among analytical results of all participants, 26.34%~504.22% of coefficient of variation. But the variation of analytical performance in the 2nd and 3rd rounds decreased to 40.42%~52.55% and 10.74%~20.98%, respectively. The difference of analytical performance among participants was decreased by operation of subsquent round. By distribution of Running Performance Index (RPI), over 50% of participants belongs to Category 3 in the first round. The average percentage of participants assigned to Category 3 in the 2nd and 3rd round was decreased to 37.2%. A definite analytical performance improvement of participants seems to be obtained. "A" and "B" group have more participants assigned to Category 3 than those of "C" group through the distribution of RPI by group divided to similar participant. By the distribution of RPI all participants, the percent of participant being over 200 RPI in the 1st round was 43%~52%, but decreased to 9%~29% and 9%~27%, in the 2nd and 3rd round, respectively. These results mentioned above indicate that the analytical performance of all participants have been improved by subsquent Quality Control Program although newcomers joined and a few participants droped out. But, there are some participants with poor analytical performance. Industrial Health Research Institute (IHRI) will offer service such as education, communication and visitation to them, and improve quality of their analytical performance in the future.

The purpose of this study is to examine factors causing the female adolescent sexual activity. 201 female adolescents participated in this study. Each participant was classified into the sexual activity experience or non-sexual activity experience group on the basis of survey. In total, 87 female adolescents have sexual activity experience, and 114 female adolescents have non-sexual activity experience. Analysis reported that sexual activity experience group was more positive on the adolescent sexual activity than non-sexual activity experience group. Also sexual activity experience group has more peers having sexual activity and pregnancy experience than non-sexual activity experience group. And, sexual activity experience group was more coping level and lower father social support than non-sexual activity experience group. Logistic regression analysis was conducted in order to determine the extent to which the attitude on the adolescent sexual activity, peer group's sexual experiences, social support, and coping factors affected on female adolescent sexual activity. As a results, peer's sexual activity and peer's pregnancy factors were significantly associated with it. Finally based on the results, the intervention strategies were suggested.

Community facilities in most rural villages have many problems in the aspect of their size or functions as well as they are generally too superannuated to support diverse community activities; which results in a low degree of inhabitants' satisfaction with community facilities, and inconvenience for using them. Therefore, it may carefully be said that it's time to need the established studies that are necessary with consider to community facilities which can reflect inhabitants' diverse activities. In this study, 5 places which the most common events among the major monthly events of total 25 rural villages were held were selected as the subject place for survey; and then investigated, by means of the participant observation method, the using behavior of inhabitants who used community facilities. Focusing on size, factors, and layout that were being faced by community facilities in most rural villages, This study investigated the number of users, the characteristics of traffic line and behavior, and the using behavior by group; through considering their correlation with the physical setting of community space, it deduced the problems of use; and it proposed the direction of improvement on the basis thereof. Therefore, this study will serve in the future as useful basic materials for designing a rural village's community facilities in consideration of size, factors and layout which can appropriately support inhabitants' community activities.

The purpose of this study is to investigate a student's career maturity during a career exploration program based on the ecological system perspective and to propose directions for the career maturation process to help H. Meister High School students to get jobs. A single-case 12-session career exploration program was applied to a first-year student at H. Meister High School in U. City for 90 minutes per session twice a week. To verify the effects of the program, this study conducted a pre-test and post-test of career maturity to analyze changes. In addition, the study qualitatively analyzed changes in the program activity sheets and process evaluation sheets per session. The results of the study are as follows: Firstly, the career exploration program based on the ecological system perspective conducted with the student at H. Meister High School improved the student's career maturity. Secondly, changes were observed in the scores in the sub-factors of career maturity between the pre-test and the post-test. Significant differences in the results of the analysis of the sub-factors of career maturity indicate that the program had a statistically positive impact on the career maturation process of the participant. In conclusion, as a result of the in-depth implementation of the program for 12 sessions, the participant expressed his desires which were clarified. In addition, a positive career maturation process appears to have taken place, owing to the self-directed program that led the participant to initiate plans and explore his career by himself. This study was conducted as a single case based on the ecological system perspective concerning career exploration and the career maturation process, but it will be necessary to expand the study to investigate the effects of group counseling, information exchange considering peer influences, common discussions on goal-setting, and other methods on the career maturation process.

The original focus of this study was to investigate the immediate effects of lumbar rotational mobilization on the one-legged standing ability. Fifteen subjects (6 men and 9 women, mean age = 22.77 (SD = 1.21), mean height = 165.46cm (SD = 11.65), mean weight = 61.46kg (SD = 8.29) volunteers from healthy individuals were recruited and randomized to a lumbar rotational mobilization (LRM) group and a trunk rotational exercise (TRE) group. Mobilization (grade 3 or 4) was applied to the LRM group on the lumbar spine (L1 to L5) in a side-lying, and trunk twist exercise (left and right side) was applied the to the TRE group with lunge position. Center of pressure (COP) and the velocity of the center of pressure (VCOP) of each participant were measured as a balance ability through one leg standing position. Results are as follows. In within-group difference, the COP of the LRM group reduced during standing with the right foot, but the VCOP change of the LRM was not statistically significant. In between-groups difference, COP of TRE group was decreased compared with LRM group only during left leg standing in the eyes (p <.05). The results of this study suggest that LRM is more effective than TRE in improving balance ability.
