모듈 테스팅은 소프트웨어 라이프 사이클의 테스팅 단계의 시작 부분으로 가장 많은 소프트웨어 에러를 발견하는 중요한 역할을 한다. 따라서 이 단계를 효율적으로 할 수 있는 툴을 구성한다면 시간과 인력을 절약하게 될 뿐만 아니라 에러 발견을 쉽게 하므로 테스팅 비용을 절감하게 된다. 본 논문은 프로그램 경로 테스팅을 효율적으로 하기 위한 툴을 정적 동적 방법으로 연구하였다.
공공조직의 진성리더십이 집단창의성에 미치는 영향과 개인-환경적합성의 매개효과
김응조 ( Eung Jo Kim ),홍아정 ( Ah Jeong Hong ) 한국인력개발학회 2015 HRD연구 Vol.17 No.2
급변하는 글로벌 사회에서 창의성은 더 이상 개인발전에만 국한시킬 수 없는 개념으로, 민간 기업은 물론 공공조직에도 그 중요성이 강조됨에 따라 조직의 창의성 발현을 위한 다양한 시도와 함께 창의적인 조직문화와 환경구축을 위해 심혈을 기울이고 있다. 이러한 맥락에서 이 연구는 우리나라 공공조직의 창의적 경영환경 조성을 위한 주요 요인으로 구성원의 집단창의성을 설정하고 이를 증진시키기 위한 선행요인으로 진성리더십과 개인-환경적합성 간의 구조적 영향관계를 실증적으로 분석하는 데 초점을 두었다. 연구목적을 달성하기 위해 전국 각 지역에 지역본부를 두고 있는 공기업 구성원을 대상으로 설문조사를 실시하였으며, 설문자료를 토대로 진성리더십과 집단창의성의 영향관계와 두 변수 사이의 개인-환경 적합 수준을 매개변수로 설정하여 매개효과를 분석하였다. 분석결과, 진성리더십은 집단창의성에 긍정적인 영향을 미치는 것으로 밝혀졌으며, 개인-환경적합성은 진성리더십과 집단창의성과의 관계에서 부분매개효과를 갖는 것으로 나타났다. 이 연구를 통해 공공조직의 진성리더십과 개인-환경적합성을 고려한 실질적 지원체계가 집단창의성을 향상시킬 수 있다는 시사점을 도출 할 수 있었다. The importance of creativity has expanded to public sector as well as corporate sector since it has been considered as one of the critical elements to succeed in this ever-changing, competitive society. In this regard, the research examined influential variables that can improve group creativity, especially focusing on the effects of leadership and organizational environment. The purpose of the study was to analyze the influential relationship between public organization employees’ authentic leadership and group creativity and the mediating effect of person-environment fit between the two variables. 195 employees of public organization were randomly selected to participate and answer the online questionnaire survey. The study shows that the employees who perceived greater authentic leadership and person-environment fit had positive effect on group creativity. Also, all components of person-environment fit had partial mediating effects upon authentic leadership and group creativity. Based on the findings of the study, designing a support system that takes authentic leadership and person-environment fit into account in public organizations will improve their group creativity.
만성정신분열병 환자들에서 비정상적 불수의 운동과 혈당, 지질과의 상관관계

Objects:It has been reported that the incidence of tardive dyskinesia(TD), the remarkable abnormal involuntary movement, was higher in the schizophrenics with high blood sugar levels and that TD had been improved by small amount of insulin-injection for 90 days. And also it was generally known that the blood lipids were higher in the schizophrenics with tardive dyskinesia. Thus, we tried to replicate the correlations of abnormal involuntary movements with blood sugar levels and blood lipids in chronic schizophrenics treated with antipsychotics. Methods:Thirty-eight male schizophrenic inpatients who were stable in clinical state with medications, were included. The patients who had been already diagnosed as diabetes mellitus(DM), organic brain disorder, substance- related disorder, physical illness were excluded and also we excluded female patients to remove the hormonal effect on TD. Eleven patients who ranked higher(above five) in the Abnormal Involuntary Movement Scale(AIMS) were assigned into 2 groups, a dibenese group and a placebo group. Diabinese or placebos were administrated for 3 weeks with antipsychotics and AIMS was rechecked. Results:There were no correlations between the total AIMS scores and blood sugar and lipids levels in all subjects. The means of total and subscale scores(objective, face, and extremity) of AIMS did not reveal statistical significances between diabinese and placebo groups. However(total, jaw, face, upper arm, and objective feeling), were statistically higher in the diabinese group than those in the placebo group. And correlations of total cholesterol(TC) with fast blood sugar(FBS), weight with body mass index(BMI) and waist, total glycerol (TG) with BMI were statistically significant. Conclusion:In this study, there were statistical significances in the changes in ratings of AIMS scores between the diabinese group and the placebo group. Application of oral hypoglycemic agent might be a way of improving abnormal involuntary movements in schizophrenics with abnormal involuntary movements or TD. Althogugh it was not certain that there were correlations of abnormal involuntary movement with blood sugar and lipids, correlations of TC/TG with AIMS, of FBS with AIMS cautiously suggest that the regular check of $HbA_1C$, waist, and weight are recommended for schizophrenics.

In this study, we developed an ensemble Kalman filter (EnKF) for a track-before-detect (TBD) radar-tracking algorithm. The TBD algorithm is used in environments where target detection is difficult, owing to heavy clutter environments, small radar cross-section targets, and stealth targets. Generally, reducing the threshold for the TBD algorithm increases nonlinearity and false alarms. Under these conditions, it is difficult to achieve desirable estimated accuracy of the tracking filter if conventional Kalman filter methods are used. In this study, it was found that the estimated accuracy of the tracking filter effectively improved the EnKF and extended Kalman filter root-mean-square error rates by 40% and 20%, respectively, when an EnKF was applied in TBD processing.

This study aims to explore daily changes in the ecological environment of the elderly caused by participation restrictions in welfare centers due to COVID-19. Eleven volunteers who were active in a welfare center were selected for in-depth interviews and interviews with individual focus groups. According to the study, the participants are experiencing isolation and depression as participation restrictions lead to constraints on physical activities. Therefore, to improve the quality of life of those in danger of social isolation, online learning should be used as an alternative to non-face-to-face communication during COVID-19. It is expected that continued interest will lead to the search for alternatives and active research in this area.

N/A Miliary Tuberculosis is an illness produced by acute dissemination of tubercle bacilli via the blood stream. In chest roentgenogram, a diffuse miliary infiltrates are usually seen, but normal or suspicious ground glass pattern also can be seen in early manifestation. Ten patients of miliary tuberculosis who underwent whole-body 67Ga-citrate scintigraphy were evaluated retrospectively to study usefulness of Ga-scan for early diagnosis of miliary Tbc and evaluation of disease activity. All of ten patients demonstrated significantly diffuse bilateral pulmonary uptakes on 48 hours image. All of three patients of ground-glass pattern in chest roentgemogram also demonstrated increased uptakes. In the statistical analysis, the severity of chest roentgenographic findings showed positive correlation with the activity on Ga-scan. These results suggest that Gallium scan is useful for diagnosis of early miliary tuberculosis and for evaluation of disease activity on follow-up examination of miliary tuberculosis of lung.

This paper is a study of metal detection methods using multiple MI sensors using deep learning. The MI sensor is a sensor that measures the impedance change of an atypical wire by the electrical conduction and transmittance of a detector. Simple principles, small power consumption, and compact manufacturing are possible. This is a field-available sensor that requires limited weight and power, such as a mobile environment. However, sensors are generally weak in strength due to the nature of sensors that detect changes in magnetic fields. This paper compares and analyzes the detection performance with the depth of each network for location detection via RNN on 16-channel raw data extracted from sensors in a self-impedance manner.
