  • Many students who attend university are worried about their future employment and academic achievement. Self-leadership is the ability to deal wisely with employment matters and to recognize the employment strategies of students who display self-leadership qualities. For this purpose, 320 questionnaires were distributed to students attending universities in Seoul. The 304 collected questionnaires were used as data for the final analysis. First, the university students' average self-leadership rate was 3.73, and their average employment rate was 3.24. In terms of self-leadership by subordinate domains, the most common strategy was to introduce "natural compensation activities", and the least common strategy was to focus on "inner compensation". For the employment strategy, "academic credit" was the best managed, and "active behavior" was the least well managed. Second, in terms of the differences in self-leadership due to social demographic variables, the self-leadership levels showed significant differences, according to their credits in general. Furthermore, they showed significant differences depending on gender and the leadership experience among the subordinate variables. Moreover, the university students' employment strategies showed significant differences according to gender, leadership experience and leadership education. Third, in terms of the difference between self-leadership and employment strategies due to psychological variables, self-efficacy and university-life satisfaction levels made significant differences in terms of self-leadership. Fourth, the group with high self-leadership levels also had highly developed employment strategies, compared to the group with low self-leadership levels. Fifth, after analyzing the social demographic variables, the psychological variables and the influence of self-leadership, it appears that the explanation level increased at each step. This study demonstrates that experiencing many opportunities that promote self-leadership during university causes students to worry about their future careers and prohibits them from developing into independent, responsible adults who can accomplish their goals.

  • In recent years, Korea encourages teachers to do STEAM education(Science, Technology, Engineering, Arts & Mathematics), which includes Arts to STEM education to train creative science technology talent. Related to this, we developed a subject substitute STEAM program for the 6th grade students in elementary school and applied it in a field. The STEAM program which substitutes contents in curriculum related to Energy unit was developed and it was taught to twenty four sixth grade students during regular classes. During the classes, all activities of students were observed and they were written in recording notes during the observation. After all STEAM program ended, how students recognize the subject substitute STEAM program compared to general class, understand learning contents and think about the program before and after the STEAM classes were analyzed through questionnaire and interviews. The results were as follows. First, some students had difficulty in reconciling different ideas in group, creative thinking and crafts but most students liked the STEAM classes because many activities are fun and it is easy to understand. Second, learners regarded practical use of knowledge, learning different subjects together and interests as the reasons they can understand learning contents easily during STEAM program. Third, learners recognized STEAM classes are good to understand knowledge, think creative ideas and improve social skills after the STEAM classes while they showed anticipation, worry and fear before taking the classes. It is found that a subjective substitute STEAM program is helpful to increase learners' interests in learning, understand learning contents, increase creativity and have a good personality through a qualitative research.

  • 최근 간척사업으로 조성된 간척농경지의 영농에 있어 가장 빈번하게 발생하는 영농사고는 염수에 의한 농작물의 염해피해로 간척지를 농경지로 사용함에 있어 최우선적으로 선행되어야 할 과제는 제염화이다. 현재까지 간척지의 제염화를 위한 활발한 연구 및 기술개발이 진행되고 있으나, 현재의 기술로 단시간 내에 간척지를 제염화하는 것은 사실상 불가능한 실정이며, 간척농경지에 사용되는 관개용수 또한 대부분 간척으로 조성된 담수호나 조수간만의 영향을 받는 하구원의 수원을 염분 농도를 고려하지 않은 상태에서 이용하고 있어 기상조건, 배수갑문 오동작 등으로 인한 염분농도 상승에 의해 피해가 발생되고 있다. 본 논문에서는 WCDMA 모듈을 이용하여 외부 서버로 데이터를 전송을 수신받아 실시간으로 현재 염분 수치가 실시간으로 증가되는 그래프를 구현하였으며, 또한 일정 수치이상으로 올라가면 경보음을 알릴뿐만 아니라, 데이터가 실시간으로 저장되 사용자가 다시 확인할 수 있는 실시간 염분 모니터링 시스템을 구현 하였다.

  • Purpose: This study is to study sleep disorder, sleep pattern, and depression in adult women, and to offer basic data for a program of the improvement of women's health and nursing intervention. Method: A structured questionnaire was carried out from September 1, 2001 to October 30, 2001 on the subject of 441 females, who are above 18 years old and lived in Seoul. This research tool measured insomnia with APA's insomnia scale(1994), sleep pattern and sleep disorder factors scale(Shin et al(1999)'s), and depression with Radloff's CES-D scale (1977). The data were analyzed with a SPSS program for descriptive statistics, ${\chi}^2-test$, and t-test. Result: The result were as follows; 1) 35.1% of all participants have insomnia. 2) Sleep disorder group appeared shorter($50.98{\pm}29.41min$.) than normal group($73.03{\pm}38.7min$.) in daytime sleepiness(p=0.001). 3) Factors of sleep disorder were stress(76.6%), worry(55.6%), without reason(39.6%), and noise outside(37.4%). 4) In relation between sleep disorder and depression, group with sleep disorder($20.20{\pm}11.06$) marked higher depression score than normal group($14.25{\pm}8.81$)(p<0.0001). Conclusion: Based upon these finding, sleep disorder in adult women was influenced by psychological factors, group with sleep disorder showed a higher depression score than normal group, and which indicated correlation with sleep disorder and depression. This study shows that nursing intervention on women's sleep disorder and depression is needed and further research be done to verify the results.

  • 2014년부터 사회와 과학 과목에 대한 디지털교과서가 개발되어 초등학교와 중학교에 시범 적용되어지고 있다. 이에 대해 일부에서는 디지털교과서 사용에 따른 학생들의 인터넷 중독 가속화를 우려하고 있다. 그러나 아직까지 충분한 연구가 진행되지 않아 디지털교과서의 사용이 학생들의 인터넷 중독을 가속화시키는지를 파악할 수 없는 형편이다. 이에 본 논문에서는 디지털교과서의 사용이 학생들의 인터넷 중독에 영향을 미치는지를 조사분석하였다. 그 결과, 디지털교과서를 사용하지 않는 집단에서 디지털교과서를 사용하는 집단보다 인터넷 중독 잠재적 위험 사용자군이 약 1.9배 높은 것으로 나타났으나 두 집단 간의 교차분석을 실시한 결과 95% 신뢰수준에서 유의미하지 않은 것으로 나타났다. 결국 디지털교과서의 사용이 학생들의 인터넷 중독에 영향을 미쳤다고 보기는 어렵다고 볼 수 있으며, 학생들의 인터넷 중독은 인터넷 사용의 시간과 빈도보다는 어떤 환경 하에서 사용하게 되는지에 더 큰 영향을 받을 수 있다고 추측되어졌다.

  • Purpose: This study was conducted to examine the adaptation experience of male nurses working in general wards. Methods: Experiential data was collected from 16 general ward nurses through in-depth interviews. Participants were selected from male nurses working in the general wards with over one year of clinical experience at a tertiary university hospital. The main question was "Can you describe your adaptation experience in the general ward as a nurse?" All interviews were recorded and transcribed, then analyzed using Colaizzi's method. Results: Four categories were derived from the analysis: 'difficulties from task adaptation by characteristics', 'limited nursing situation and circumstance as a male nurse', 'efforts to adapt at general nursing unit', and 'self-worth, and worry about something as a male nurse'. Conclusion: Male nurses had a difficulty adapting to work in wards due to lack of multi-tasking skills, as well as some social prejudice or negative views on male nurses. Establishing reasonable guidelines for male nurses in practice, promoting their responsibilities to patients, developing mentoring programs, and reassessing the policy of assigning male nurses to general wards are recommended to help in better adaptation.

  • 본 연구는 구조방정식모형 (SEM)을 활용하여 개인연금의 가입에 영향을 주는 심리요인들 간의 인과관계와 장수정서의 매개효과를 실증하고자 하였다. 전국 7대 도시에 거주하는 928명의 일반인을 대상으로 실시한 설문자료를 활용하여 분석하였다. 실증분석 결과 개인연금의 가입에는 장수가능성, 대처효용성, 장수지식 (인지요인), 보험사 신뢰 (사회요인), 금융이해력 (금융요인)이 직접적으로 영향을 주었다. 장수감정, 장수가능성, 국가신뢰, 대처효용성이 장수정서 (두려움과 걱정)에 영향을 주었으나, 장수정서를 매개로 하여 개인연금 가입에는 영향을 주지 못하였다. 본 연구를 통해 보험사에 대한 고객의 신뢰도와 잠재고객의 금융지식수준을 높이는 것이 개인연금의 판매활성화에 중요한 요인임을 재확인하였다. 장수할 가능성을 높게 생각하는 사람들이 개인연금을 가입한다는 사실은 연금보험시장에서도 역선택 가능성이 높음을 보여주었다.
