장선숙,김성준,Jang, Sun Sook,Kim, Seong Joon 한국농공학회 2017 한국농공학회논문집 Vol.59 No.3

The purpose of this study were to evaluate the effect of best management practices (BMPs) of Haean highland agricultural catchment ($62.8km^2$) under future climate change using SWAT (Soil and Water Assessment Tool). Before future evaluation, the SWAT was setup using 3 years (2009~2011) of observed daily streamflow, suspended solid (SS), total nitrogen (T-N), and total phosphorus (T-P) data at three locations of the catchment. The SWAT was calibrated with average 0.74 Nash and Sutcliffe model efficiency for streamflow, and 0.78, 0.63, and 0.79 determination coefficient ($R^2$) for SS, T-N, and T-P respectively. Under the HadGEM-RA RCP (Representative Concentration Pathway) 4.5 and 8.5 scenarios, the future precipitation and maximum temperature showed maximum increases of 8.3 % and $4.2^{\circ}C$ respectively based on the baseline (1981~2005). The future 2040s and 2080s hydrological components of evapotranspiration, soil moisture, and streamflow showed changes of +3.2~+17.2 %, -0.1~-0.7 %, and -9.1~+8.1 % respectively. The future stream water quality of suspended solid (SS), total nitrogen (T-N), and total phosphorus (T-P) showed changes of -5.8~+29.0 %, -4.5~+2.3 %, and +3.7~+17.4 % respectively. The future SS showed wide range according to streamflow from minus to plus range. We can infer that this was from the increase of long-term rainfall variability in 2040s less rainfalls and 2080s much rainfalls. However, the results showed that the T-P was the future target to manage stream water quality even in 2040s period.

This study aims to evaluate the Soil and Water Assessment Tool (SWAT) hourly hydrological modeling performance and compare it with daily SWAT modeling parameters. For the Byeolmicheon catchment ($1.17km^2$) located in the upstream of Gyeongancheon watershed and total 18 storm events measured during 3 years (2011-2013), the hourly SWAT was calibrated and validated using the Green and Ampt (G&A) infiltration equation. The determination coefficient ($R^2$) and Nash-Sutcliffe model efficiency (NSE) of hourly SWAT discharge were 0.81 and 0.73 respectively, and the most sensitive parameter was soil saturated hydraulic conductivity (SOL_K) and calibrated with the average value of 0.075 mm/hr. In addition, the hourly SWAT simulation by G&A was compared with the daily SWAT simulation by SCS-CN (Soil Conservation Service-Curve Number) method for the whole 3 years period. The houlrly G&A results showed $R^2$ and NSE of 0.71 and 0.50, and the daily SCS-CN results were 0.71 and 0.66, respectively. The SOL_K by daily SCS_CN method was calibrated at 75.5 mm/hr, 1,000 times greater than the hourly G&A method. The next sensitive parameters for the hourly simulation were lag time of lateral flow (LAT_TIME) and lag time of surface runoff (SURLAG).

Purpose: There are large differences between medical school curricula and those of other disciplines and graduate schools. Counseling program is designed to help participants understand their innate tendencies and have indirect experiences with the 16Myers-Briggs Type Indicator (MBTI) types, which can lead to better interpersonal relationships. Methods: The experimental and control groups, which were sampled randomly, comprised 34 students each. Each group was consisted of 17 females and 17 males. We implemented a counseling program (understanding oneself, understanding others) only to the experimental group, not the control group. The effects of the program were analyzed by t-test and analysis of covariance (ANCOVA). The data were analyzed using SPSS 17.0 Window. Results: For the Human relationship scale as a whole, the experimental group showed an increase from 3.641 to 3.846 (p=0.001). With regard to the subcategories, satisfaction increased from 3.705 to 4.022 (p=0.000), trust increased from 3.480 to 3.715 (p=0.015),intimacy increased from 3.833 to 4.019 (p=0.007), and openness increased from 3.435 to 3.700 (p=0.006). Conclusion: This program improved interpersonal relationships by helping new students understand each other, build a rapport,and understand their personalities well with open minded attitudes. Their relationships gradually became more intimate than awkward through this program.

This study is to assess the effect of non-point source pollution discharge loads between tillage and no-tillage applications for upland crop areas using SWAT (Soil and Water Assessment Tool) watershed modeling. For Byulmi-cheon small rural catchment ($1.17km^2$) located in upstream of Gyeongan-cheon watershed, the rainfall, discharge and stream water quality have been monitored in the catchment outlet since 2011. The SWAT model was calibrated and validated in hourly basis using 19 rainfall events during 2011-2013. The average Nash-Sutcliffe model efficiency and $R^2$ (determination coefficient) for streamflow were 0.67 and 0.79 respectively. Using the 10 % surface runoff reduction from experiment results for no-tillage condition in field plots of 3 % and 8 % slopes under sesami cultivation, the soil saturated hydraulic conductivity for upland crop areas was adjusted from 0.001 mm/hr to 0.0025 mm/hr in average. Under the condition, the catchment sediment, T-N (total nitrogen, TN), and T-P (total phosphorus, TP) discharge loads were reduced by 6.9 %, 7.4 %, and 7.7 % respectively.

장선숙,염인숙,박상우 한국교정학회 2017 矯正硏究 Vol.- No.76

The purpose of this study was to find out how correctional officers prepare for their life after retirement. We conducted in-depth interviews of 10 correctional officers who within 5 years before retirement and preparing for life after retirement, and analyzed the collected interview data using Consensual Qualitative Research(CQR) method. Through this analysis, correctional officers’s retirement preparations appeared in 4 categories and 11 subcategories. 4 categories are as follows : ‘The meaning and reality of retirement plan’, ‘Personal resources for preparing for retirement’, ‘Specific arrangements for retirement’, ‘Alternative to preparing for retirement’. The synthesis of research results is as follows. The reason why correctional officers want to work after retirement is, ‘in order to live a healthy life after retirement’, ‘to feel pride by contributing to society’, ‘to accomplish something similar to an unrealized dream’. And the difficulties in preparing for retirement is the economic circumstances and the working environment, and the current working experience did not help career transition after retirement. Based on research findings, We presented policy measures to help correctional officer’s retirement preparation and the direction of retirement support program that meets the characteristics of correctional officers. 본 연구의 목적은 교정공무원들이 퇴직 후 삶을 어떻게 준비하고 있는지를 알아보기위한 것이다. 이를 위해 퇴직 준비를 하고 있는 5년 이내 퇴직 예정 교정공무원 10명을대상으로 심층면접을 실시하였고, 수집된 자료를 합의적 질적 연구방법(CQR)으로분석하였다. 분석결과 교정공무원들의 퇴직준비는 4개 범주와 11개의 하위 범주로 도출되었는데, 4개의 범주는 ‘퇴직준비의 의미와 현실’, ‘퇴직준비를 위한 개인적 자원’, ‘퇴직을 위한구체적인 준비행동’과 ‘퇴직준비를 위한 대안’이다. 연구결과를 종합해 보면, 교정공무원들이 퇴직 후에도 일을 하려는 이유는, ‘퇴직 후 건강한 삶을 살기 위해’, ‘사회에 기여함으로써 삶의 보람을 느끼기 위해’, ‘이루지 못한 꿈과 유사한 일을 하기 위해’서 인것으로 나타났다. 그리고 재직 중 퇴직준비의 어려움은 경제 사정과 근무 환경으로 나타났고, 현직에서의 업무 경험은 퇴직 후 진로 전환에 크게 도움이 되지 않는 것으로 나타났다. 연구결과를 바탕으로, 본 연구는 교정공무원의 퇴직준비를 돕기 위한 정책적 방안과교정공무원의 특성에 부합하는 퇴직지원프로그램의 방향을 제안하였다.

장선숙,서지현,조경제,홍순찬,우향옥 한국의학교육학회 2010 Korean journal of medical education Vol.22 No.2

Purpose: The purpose of this study was to identify the correlation between communication skills for emotional empathy and academic achievement on the Clinical Performance Examination (CPX). Methods: One hundred twelve medical school students were observed to determine the extent to which they applied communication skills for emotional empathy (preparation stage: interview attitude, respect; rapport stage: encouragement, active listening, will for support; empathy stage: verbal expression empathy, nonverbal expression empathy, acceptance) to the CPX, as well as their level of understanding of these skills to calculate the Pearson r, which can be used to determine the correlation between communication skills and academic achievement (hematochezia, fatigue, abnormal menstruation, chest pain, alcohol problems). Results: Male students had higher scores than females for all communicational skills except verbal expression empathy. Fourth-year students had statistically more significant correlations than third-year students with regard to the rapport stage 'active listening' and empathy stage 'nonverbal expression' and abnormal menstruation and chest pain. Correlations were also more significant for hematochezia in the preparation stage 'interview attitude,' rapport stage 'encouragement,' and empathy stages 'verbal and nonverbal expression' and 'acceptance.' The empathy stage 'nonverbal expressions' was more significant for fourth-year students with alcohol problems. Third-year students largely had negative correlations between emotional empathy communication skills and CPX academic achievement, especially between the preparation stage 'respect' and abnormal menstruation, and between the rapport stage 'encouragement' and hematochezia. Conclusion: There was a significant correlation between hematochezia, wherein MS students deliver bad news to patients, and communication skills for emotional empathy.

The purpose of this study was to examine the effects of a multi-dimensional group program using video feedbacks for the reduction of public speaking anxiety on the presentation anxiety, self-efficacy and presentation behaviors among the third grade female students in a commercial high school. Among the students who had high scores in a presentation anxiety test, 30 students who wanted to participate in this study were selected and assigned randomly into two groups. The subjects of experimental group participated in the 8 session intervention program once or twice a week. It took 60 ~ 90 minutes for each session. Pre-test and post-test scores of experimental group and control group were compared using two-way ANOVA. The results revealed that the experimental group showed lower presentation anxiety, higher self-efficacy, and more appropriate presentation behaviors than the control group after participating in the program. The meanings of his study were as follows. It was replicated some results of previous studies that the multi-dimensional intervention including video feedback, cognitive techniques, relaxation and coping strategies was useful for the reduction of public speaking anxiety through the controled study using random assignment and several measures including rating scales by others as well as self-reports. Finally, Some limitations of this study and the direction for future study were discussed.

교정공무원의 퇴직 후 진로전환경험에 관한 근거이론적 분석

장선숙,안윤정 아시아교정포럼 2019 교정담론 Vol.13 No.3

Today, a variety of changes are followed in the professional world as increased life expectancy. However, most public officers are passive in preparing for retirement as they are guaranteed job security under the law while in office and pension for public officer after retirement. Most public officers have difficulty adjusting to and coping with the rapid changes of this age due to the special nature of working for public organizations. Some people live a satisfying second act of life, doing new work, thanks to their own strengths, accumulated work experience and continued self-development in the incumbent. We interviewed 21 people who worked as correctional officer for more than 28 years and succeeded in career transition after retirement, and categorized and analyzed data on the work experience, retirement preparation process, meaning of work, etc. in the way of Strauss and Cobbin. The conclusions of this study are as follows: First, the reason why correctional officers do new work after retirement was self-realization rather than economic compensation. Second, the work experience of a retired correctional officers turned out to be much help to the new job, especially ‘deep understanding and acceptance of people through the experience of various people’ helped all subjects. Third, in the career transition of correctional officers, it indicated a higher relationship between individual competence and social capital than position while in office. Fourth, the most important and prerequisite for career transition after retirement is to establish career goals through self-discovery and self-understanding processes. These were the starting points for career transition. Fifth, when concrete preparations were made for career transition, the career transition process was smooth, the time required for the transition was short, and the satisfaction level was high. This study will be specific educational material for retirement arrangements. It will also serve as the basis for the introduction of retirement support programs that conform to the characteristics of correctional officers. 오늘날 수명증가에 따라 직업세계에 다양한 변화들이 뒤따르고 있지만 대부분 공무원들은 재직 중 법률에 의한 직업안정과 퇴직 후 공무원연금 보장되어 퇴직준비에 수동적이다. 대부분 공무원들은 장기간 공공기관의 특수성의 영향으로 빠른 시대변화의 흐름에 적응하거나 능동적인 대처가 어려운데도 일부는 현직에서부터 자신의 강점과 축적된 일경험, 그리고 지속적인 자기계발을 통해 새로운 일을 하며 만족스러운 인생2막을 살아가는 경우가 있다. 본 연구는 28년 이상 교정공무원으로 재직 후 퇴직하고 또 새로운 일로 진로전환한 21명을 대상으로 심층면담하여 교정공무원 재직 중 일경험, 퇴직준비과정, 일의 의미 등에 대한 자료들을 분석하여 Strauss와 Cobin의 방식으로 분석하였다. 이 연구의 결론은 첫째, 교정공무원이 퇴직후 새로운 일을 하는 이유는 경제적인 보상보다도 자기실현의 의미가 컸고, 둘째, 실제 퇴직 후 진로전환 한 경험자들을 통해 본 교정공무원의 일경험은 새 일에 많은 도움이 되었고. 참여자들 모두에게서 도움 되는 전직 일경험은 ‘다양한 사람들을 경험하여 사람에 대한 깊은 이해와 수용’이었다. 셋째, 교정공무원의 진로전환에서는 재직 시 직급 보다는 개인역량과 사회적자본이 높은 관계를 나타내었고, 넷째, 퇴직 후 진로전환을 위해 가장 중요하고 선행되어야 할 부분은 자기탐색과 자기이해과정으로 진로목표를 수립하는 것이 진로전환의 출발점이었다. 다섯째, 진로전환을 위해 구체적인 준비를 한 경우는 진로전환과정이 순조롭고, 전환을 위한 소요 시간도 짧았고 만족감도 높게 나타났다. 본 연구는 퇴직준비에 구체적인 교육자료가 되고, 교정직 공무원 특성에 맞는 퇴직지원프로그램 도입에 기초가 될 것이다.
