목적 본 연구의 목적은 노인의 스마트폰의 사용 유무에 따른 인지기능과 우울감, 고독감의 관계를 파악하고자 하며, 추후 노인 작업치료를 시행함에 있어 노인의 스마트폰 사용에 대한 고려를 장려하기 위함이다. 연구방법 2016년 8월 18일부터 9월 21일까지 부산 소재의 K복지관, G양로원, 김해 소재의 H아파트, D아파트의 노인정에서 65세 이상 노인 총 54명을 대상으로 실시하였다. The Korean Version of Montreal Cognitive Assessment(MoCA-K), Korea UCLA Lonelines scale(UCLA 고독감 척도), Geriartric Depress Scale Short Korea Version(GDSSF-K)를 사용하여 평가를 하였으며, 빈도분석과 t-test, 회귀분석을 이용하여 분석하였다. 연구결과 스마트폰 사용유무에 따른 인지기능(p<0.001)과 우울감(p<0.05), 고독감(p<0.001)은 유의미한 차이를 보였다. 인지기능과 고독감 사이에는 유의미한 상관관계를 보였지만 인지기능과 우울감, 우울감과 고독감 사이에는 유의미한 상관관계를 보이지 않았다. 결론 본 연구를 통해, 스마트폰 사용이 노인의 인지기능 유지 및 향상이 된다는 것을 알 수 있었으며, 노인의 우울감과 고독감을 낮춰준다는 점을 알 수 있었다. 향후 건강한 노년을 위해 노인의 스마트폰 사용을 권장하고 스마트폰 교육이 활성화 될 것을 기대한다. Objectives : The purpose of this study was to identify the effects of use of smartphone and cognitive function on depression, and Loneliness of life in elders. Methods : From August 18 to September 21, 2016, a total of 54 elderly people aged 65 years or older were interviewed at K Welfare Center in Busan, G Nursing Home, H Apartments in Gimhae, and D Apartment. The Korean version of Montreal Cognitive Assessment (MoCA-K), Korea UCLA Lonelines scale and Geriatric Depress Scale Short Korea Version (GDSSF-K) were used to evaluate the frequency, t-test, Pearson correlation , And regression analysis. Results : There was a significant correlation between cognitive function (p <0.001), depression (p <0.05), and loneliness (p <0.001) according to presence or absence of smartphone use. There was a significant correlation between cognitive function and loneliness, but there was no significant correlation between cognitive function and depression, depression and loneliness. Conclusion : The results suggest that an use of smartphone could be an effective improving and maintaining cognitive function, to decrease depression and Loneliness in old adults. We hope to encourage the old adults to use smartphones for healthy future ages and expect smartphone education to be activated.

Simulation plays a pivotal role in the analysis of complex systems. In this study, a job shop manufacturing system has been analyzed through DBR (Drum-buffer-rope) simulation. Specific attention has been put to examine the rate of due-date achievement. We first derived key factors affecting the system performance. We then developed ARENA simulation program based on DBR of TOC (Theory of Constraints) concepts. Based on the performance measure, factors, and experimental design, we obtained the results. We have drawn meaningful results through examination of the results. The results obtained from this study may provide a good base for practical applications.

There are two methods to make a distinction of deterioration of high-speed railway track. One is that an administrator checks for each attribute value of track induction data represented in graph and determines whether maintenance is needed or not. The other is that an administrator checks for monthly trend of attribute value of the corresponding section and determines whether maintenance is needed or not. But these methods have a weak point that it takes longer times to make decisions as the amount of track induction data increases. As a field of artificial intelligence, the method that a computer makes a distinction of deterioration of high-speed railway track automatically is based on machine learning. Types of machine learning algorism are classified into four type: supervised learning, unsupervised learning, semi-supervised learning, and reinforcement learning. This research uses supervised learning that analogizes a separating function form training data. The method suggested in this research uses SVM classifier which is a main type of supervised learning and shows higher efficiency binary classification problem. and it grasps the difference between two groups of data and makes a distinction of deterioration of high-speed railway track.
