This study checks if the PITR (Person in the Rain) test can diagnose the stress caused by school-work for middle school students, in that the PITR responses correlates with the degree of stress. The subjects in the study are 483 middle school thirdgraders from 8 middle schools in Daegu city. Research tools used are an Academic Stress Scale and a PITR test. For data analysis is adopted with t-test and Chi-square test. The results from the study are as follows. First, the stress of middle students scores 2.47/4 that means that the school stress is average, and there is no gender difference in scores. Second, PITR test shows that boys draw more rain than girls, straight rain with stronger wind, hide face more, no good facial expressions more often than girls. Girls on the contrary show more stable lines, bigger puddles, place protections more appropriately. Third, those with higher academic stress use more unstable strokes, less number of or insufficient direct protections than those with less academic stress, and draw indirect protection such as umbrellas before rain or clouds. The study concludes that a PITR test can be useful in diagnosing the academic stress of middle school students.

This study is to notify differences of PITR reaction groups classified by industrial accident. This study aims to know reaction of stress, preparation plan, and psychological resources on industrial accident workers. The research was performed as below: First, Measuring and descriptive statistical analysis were performed. twenty workers who were hospitalized by industrial accidents and twenty patients who were hospitalized by common accidents. Data were collected from March to October in 2013. Then There were classified Two groups following subjects; 'industrial accident' and 'common accident'. Second, Questionaries assessing demographic and PITR(Person-In-The-Rain) by Heidi S. Lack. Third, statistical analysis was done by SPSS for Window 18.0. To Verify the reliability of the measures and correlations between two groups, and to find out the difference of the reaction of 'stress', 'preparation plan', and 'psychological resource', were used frequency analysis and T-test. The results of this is significant personality types of industrial accident are followings; Industrial accident workers' felt more stressful, less self esteem, and less psychological resource than common accident patients.

The purpose of this study is to investigate the effect of applying a group art therapy program on self-esteem and stress for adolescents who are maladjusted to school. The subjects of this study were 6 school maladjusted adolescents enrolled in the second year of B middle school in A region, and the period was from May 12 to June 9, 2021, twice a week, for a total of 10 sessions of 60 minutes each. As a research tool, the Self-Esteem Scale(SEI) and the Person-In-The-Rain(PITR) were examined to observe the students. For data analysis, Wilcoxon test was conducted to examine the change in self-esteem, and the Person-In-The-Rain(PITR) was qualitatively analyzed to observe stress by two art therapists. The results of this study were first, that the group art therapy program had a significant effect on improving the self-esteem of adolescents and second, the group art therapy program was effective in reducing the stress. In conclusion, group art therapy can be seen to help improve self-esteem and reduce stress in school maladjusted adolescents.

Objective: To report a case of a patient with a psychosomatic disorder who complained of hyperventilation and was treated with oriental medical treatments and emotional freedom techniques (EFTs). Methods: The patient was diagnosed as having a psychosomatic disorder through an interview and several psychological tests, such as the house-tree-person (HTP) and the person in the rain (PITR) tests. We treated the patient with oriental medical treatments that included herbal medications, western medications, moxibustion, cupping, and EFT. Results: After the treatments, the clinical symptoms of the patient were improved. Conclusions: Oriental medical treatments and EFT may be effective treatments for psychosomatic disorders.

This paper presents a special protection scheme, which was established in the KEPCO (Korea Electric Power Corporation) system, against a critically low voltage profile in a part of the system after a double-circuit tower outage. Without establishing the scheme, the outage triggers the operation of a zone 3 relay and trips the component. This sequence of events possibly leads to a blackout of the local system. The scheme consists of an inter-substation communication network using PITR (Protective Integrated Transmitter and Receiver) for acquisition of the substations' data, and under-voltage load shedding devices. This paper describes the procedure for determining the load shedding in the scheme and the experiences of the implementation.

유무기 하이브리드 금속-할라이드계 페로브스카이트(organic-inorganic metal halide perovskite) 페로브스카이트 반도체 소재는 광전자 소자와 소재 연구에 새로운 연구 흐름을 만들고 있다. 태양전지 성능이 불과 과거 몇 년 사이의 짧은 연구 기간에도 불구하고, 광-전 변환 소자 중에서도 단일 소자와 적층 소자(tandem)에서 높은 광-전 변환 효율을 나타내기 때문이다. 이러한 급격한 연구 성과와 성장에도 불구하고, 페로브스카이트 소재의 다양한 광전자 특성의 평가와 결과에 대한 논의가 필요한 상황이다. 특히 내부 이온 이동이 광전자 원거리 이동 특성 평가와 해석에 영향을 주는 경우, 페로브스카이트 소재를 기반으로 한 다양한 광전자 소자의 성능 향상과 해석에 여전히 모호함을 준다. 달리 얘기하면, 이 소재의 기초 특성을 이해하고자 적용하는 다양한 기존 특성 평가 분석법의 활용과 해석에도 복잡한 영향을 미치고 있다고 할 수 있다. 이러한 페로브스카이트 소재 내에서 광전자 원거리 이동을 측정하는 새로운 방법을 소개하고자 한다. 첫 번째 방법으로, Quasi-steady 상태에서 광전도도를 전기적 특성으로 측정하고, 광조사 하에 투과 및 반사를 광학적으로 측정하여, 전도도와 광전자 밀도를 동시에 평가하는 방법으로, photo-induced transmission and reflection (PITR) 분광분석법이다. 이 분광분석법은 실제 소자의 구동조건을 구현한 상태에서 광전자의 원거리 이동에서 발생하는 광전자 밀도 변화를 반영한 광전자 이동도 특성 평가라는 장점을 가지고 있다. 두 번째 방법으로, 기존의 연속 전압 인가 방법 대신 펄스형 전압 인가 방식을 도입하는 방법으로, pulsed voltage space charge limited current (PV-SCLC) 분석법이다. 이는 펄스형 전압 인가 방법으로 이온의 이동을 최소화하여, 전류-전압 측정에서 히스테리시스가 없고 측정결과의 재현성과 신뢰도가 매우 높은 장점이 있다.
