  • Objectives : The purposes of this preliminary study was to examine the feasibility of recruiting women into a clinical trial designed to examine the effects of acupuncture in treating urinary incontinence (UI) in premenopausal women with delivery history and the feasibility of performing the study procedures. We also tried to determine if there was preliminary evidence to suggest that acupuncture may be effective in reducing UI and improving disease-specific quality of life. Methods : This study was a pragmatic randomized clinical trial. Subjects between the ages of 20 and 49 years were randomly assigned to a treatment(n=11) or control group(n=11) and analyzed. Both groups were supposed to do Kegel exercise at home during 4 weeks and acupuncture was applied to the treatment group twice a week(8 sessions) additionally. Subjects performed 1 hour pad test and completed a 3-day urination diary, international consultation on incontinence modular questionnaire(ICIQ), and incontinence - quality of life(I-QOL) at base line and 5 weeks. Results : Both group showed improvement in 1 hour pad test and the reducing amount of UI was significantly larger in treatment group(p=0.0182). The significant improvements in ICIQ and I-QOL were also observed in treatment group and sustained until the follow-up measurement at 16 weeks. Any adverse reaction related to acupuncture did not happen. Conclusions : It was feasible to recruit subjects and perform the study procedures. The positive results of this study support the requirement for additional research investigating the efficacy of acupuncture in the treatment of UI in women.

  • Objectives: This study aims to supplement the limitations of the preliminary study and expand the use of the Child-Adolescent Functional Assessment Scale by providing standardized T-scores for measuring function in different areas, as well as guidelines for their interpretation. Methods: The Child-Adolescent Functional Assessment Scale and Korean-Child Behavior Checklist were administered to a total of 623 individuals, including 467 parents of emotionally and behaviorally disturbed elementary school students, 45 parents of emotionally and behaviorally disturbed middle school adolescents and 111 parents of elementary school students with developmental disorders, as well as to a control group consisting of 186 parents of mainstream elementary school children in the Seoul metropolitan area. Results: In contrast to the preliminary study, the emotional domain was disassociated into two factors, negative affect and emotion regulation, and the coefficient of determination for misconduct was increased significantly. Also, the overall reliability and validity of the Child-Adolescent Functional Assessment Scale were similar to those in the preliminary study, and the item structure was consistent. This study provides standardized T-scores of function in different areas based on the revised scale, and provides guidelines for their interpretation. Conclusion: The Child-Adolescent Functional Assessment Scale can assist the Child Global Assessment in Functioning in providing the information necessary for case management and treatment planning by comparing the impairment severity in each area of functioning, and also determining changes in behavior and function after treatment interventions. On the other hand, this scale has yet to clearly distinguish between rebellious behavior and misconduct. Further research is necessary to provide standards for more diverse age groups and for its utilization.

  • The purpose of the present study was to conduct a preliminary study for developing a Korean version of the Fine Motor Scale of the Bayley Scales of Infant and Toddler Development, $3^{rd}$ Edition(Bayley-III). The subjects for this study included 313 Korean infants and toddlers aged from 16 days to 42 months and 15 days. The results of this study were as follows. Firstly, the analysis of the degree of item difficulty indicated that the arrangement of the items corresponded with child development by age. Secondly, the analysis of the inter-item consistency, the test-retest reliability and the inter-rater reliability revealed a high degree of reliability of the scale. Thirdly, the Fine Motor Scale of K-Bayley-III score showed a significant high correlation with the Motor composite score but a significant moderate correlation with the Language composite score, providing evidence of its convergent and discriminant validity. This study demonstrated that the preliminary version of the K-Bayley-III Fine Motor Scales can be applied to assess the development of fine motor skills of Korean infants and toddlers.

  • Objective : The Purpose of this research is to examine the effect of Sa-am acupuncture treatment(Sim-seungkyuk) for major symptoms of Hwa-byung. Method : In this randomized, single blind, placebo-controlled study, we compared active acupuncture with sham acupuncture in the treatment for major symptoms of Hwa-byung. likert scale(5 score) for major symptom of Hwa-byung was measured as the 1st evaluative instrument, and STAXI-K, STAI-K, BDI-K and HRV were also measured as the 2nd evaluative instrument at the before treatment and after treatment. Results : 26 volunteers participated in this study by dividing two groups, each 13 persons in trial group and control group at random. In comparison of likert scale for major symptoms, after treatment the total score of likert scale for major symptoms decreased significantly in both group than before treatment. And after treatment, the total score of trial group decreased less than those of control group in comparison between two groups. especially after 2 weeks from all treatment, there was significant difference between two groups. Conclusion : We considered that Shim-seungkyuk of Sa-am acupuncture treatment will be not recommended to treatment of Hwa-byung because this study could not prove effect of Shim-seungkyuk treatment for Hwa-hyung in spite of preliminary study. This study will be used to provide a fundamental data for development of clinical research as preliminary study of Hwa-byung.

  • According to the preceding research outcomes, feasibility studies on public construction projects were incorrect and subjective. To resolve the problems, Korean government initiated Preliminary Feasibility Study (PFS) system prior to undertaking the main feasibility study. The PSF can be categorized into four areas such as road, railroad, harbor, airport, and Culture & Tourism (C&T). Especially when it comes to complex due to the introduction of five-weekday working system and local $government^{\circ}{\phi}s$ self administrative system. As a result, the standardization and legislation of the PSF can not be operated effectively. Accordingly this paper seeks to 1) identify actual condition of conducted PSF in C&T; 2) set up analytical model considering cost factor of economical efficiency and seek obstacles of PSF system; 3) suggest improvement plan for construction PSF projects.

  • Background: Prolonged sitting at work can lead to adverse health outcomes. The health risk of office workers is an increasing concern for the society and industry, with prolonged sitting work becoming more prevalent. Objective: This study aimed to explore the variation in muscle activities during prolonged sitting work and found out when and how to take a break to mitigate the risk of muscle symptoms. Methods: A preliminary survey was conducted to find out the prevalence of muscle discomfort in sedentary work. Firstly, a 2-h sedentary computer work was designed based on the preliminary study to investigate the variation in muscle activities. Twenty-four participants took part in the electromyography (EMG) measurement study. The EMG variations in the trapezius muscle and latissimus dorsi were investigated. Then the intervention time was determined based on the EMG measurement study. Secondly, 48 participants were divided into six groups to compare the effectiveness of every break type (passive break, active break of changing their posture, and stand and stretch their body with 5 or 10 mins). Finally, data consisting of EMG amplitudes and spectra and subjective assessment of discomfort were analyzed. Results: In the EMG experiment, results from the joint analysis of the spectral and amplitude method showed muscle fatigue after about 40 mins of sedentary work. In the intervention experiment, the results showed that standing and stretching for 5 mins was the most effective break type, and this type of break could keep the muscles' state at a recovery level for about 30-45 mins. Conclusions: This study offers the possibility of being applied to office workers and provides preliminary data support and theoretical exploration for a follow-up early muscle fatigue detection system.

  • Purpose: The aim of this study was to examine the preliminary effects of applying a developed web-based video education program in patients with cancer receiving chemotherapy. Methods: A one-group pre-post test design was used. The web-based video education program to prevent infection consisted of 5 subjects. The program was confirmed to be valid by an expert group of doctors and nurses. Convenience sampling of 23 subjects was performed to evaluate the effectiveness of the web-based video education program. Data were analyzed based on nonparametric statistics using SPSS 25.0 software. Results: Per the results of the study, knowledge and self-management behavior of infection prevention significantly improved after application of the program; however, there was no significant difference in self-efficacy. Conclusion: It was confirmed that the web-based video education program is effective to improve the knowledge and self-management behavior of infection prevention. However, as a preliminary study, this study did not have external validity. Therefore, it is necessary to verify the effectiveness of the program through randomized controlled trials and confirm the true infection prevention effect that was not considered in this research design.

  • As an impactive factor on industries and national economy, The Social Overhead Capital(SOC) is major factor to determine the national competitiveness and the investment of SOC is essential for its economic growth. Accordingly, introduction of the preliminary feasibility study and establishment of legal institutionalization and evaluation system has been carried out and reviewed since 1999. Nevertheless of these efforts, basic problems such as lack of scientific method for investment evaluation and loss of effectiveness on feasibility studies are continuously being brought up. Moreover, as the preliminary study to improve the mentioned problems is mainly focused on the economic and estimated demand analysis, the study of policy analysis, the most important phase during a feasibility study, is still insufficient. Therefore, in this paper, a quantitative decision-making model, to which the performance assessment method of Value Engineering(VE) is applied, is developed and proposed to improve the policy analysis of (preliminary) feasibility study that requires combining with relative studies, to induce quantitative analysis method, and to contribute the improvement of value on the political aspect for SOC investment goals and use as a strategic decision-making method by systematic analysis.
