일반적으로 북한(北韓)의 노동력(勞動力)은 "양질의 저렴한" 것으로 인식되고 있다. 이러한 인식을 근거로 북한의 노동력에 남한의 자본과 기술을 결합시키고자 하는 대북투자사업(對北投資事業)은 활발히 추진(推進)되어 왔으며, 북한의 핵문제가 해결되는 경우 급속히 실행(實行)에 옮겨지게 될 것으로 보인다. 그러나 북한의 노동력이 과연 "양질의 저렴한" 것인가의 여부에 관하여 체계적(體系的)인 검토(檢討)는 이루어진 바가 없다. 본(本) 연구(硏究)에서는 북한의 노동력이 일반적으로 인식되고 있는 바와 같이 "양질의 저렴한" 것인지의 여부, 특히 '양질' 여부에 관하여 그 타당성(妥當性)을 북한 노동력의 교육수준(敎育水準), 작업규율(作業規律), 노동생산성(勞動生産性)의 세가지 측면에서 검토하여 보았다. 그 결과 교육수준이나 작업규율에 근거하여 북한의 노동력이 '양질'이라고 생각하는 것은 무리한 평가라는 결론에 도달하였으며, 가장 설득력이 있다고 여겨지는 노동생산성에 근거한 예상도 실증분석의 결과 타당성이 작은 것으로 나타났다. 자료의 한계상 본(本) 연구(硏究)에서 대상으로 한 것은 북한(北韓)의 평균적(平均的)인 노동력(勞動力)의 질(質)로서 실제 우리 기업이 고용하게 될 노동력의 질과 차이가 있을 수 있다. 그러나 본(本) 연구(硏究)에서 분석한 바와 같이 북한의 노동력이 '저렴'하지도 '양질'도 아닐 수 있으므로 대북투자사업(對北投資事業)의 보다 신중(愼重)한 검토(檢討) 및 대북투자사업시(對北投資事業時) 보다 효율적(效率的) 북한 노동력의 활용방안(活用方案)이 모색(摸索)되어야 할 것이다.

The purpose of this paper is to implement a multiple bio-signal central monitoring system based on textile fabrics flexible platform which can obtain and monitor bio signals(heart rate, body temperature, electrocardiography, electromyogram) of workers in special working environments and additional situational information (3-axis acceleration, temperature, humidity, illumination, surrounding image). This system can prevent various accidents that may occur in the remote work environment and provide fast and efficient response by detecting workers' situations in real-time. For it, the textile fabrics flexible platform was made as innerwear or outerwear so that it does not interfere with workers' performance while collecting bio-signal and situational information, and obtained information is sent to the central monitoring system through wireless communication. The central monitoring system is based on wireless medical telemetry service of WMTS (Wireless Medical Telemetry Service); can monitor from 2 to 32 people simultaneously; and was designed so that it can be expanded. Also, in this study, to verify performance of the WMTS communication model, packet transmission rates were compared according to the distance.

이야기는 그 자체만으로 전달될 수 없기 때문에, 이야기만큼이나 중요한 것은 가공되지 않은 상태의 이야기를 구성지게 전달하는 텔링의 방식이다. 디지털 매체가 발전하고 보다 다양한 전달 방식이 등장하면서 텔링이 더욱 강조되고 이야기보다는 스토리텔링이라는 개념이 주목 받게 되었다. 이 연구는 스토리와 텔링을 구분하는 관점에서, 스토리텔링을 개발하는 작가들의 작업을 분석하고 그들을 도와주는 지원 시스템을 설계했다. 작가의 태스크를 분석하기 위해 본 연구에서는 집필 프로세스에 대해 현업 작가를 인터뷰하고 기존의 writing tool의 기능과 이야기 구조 이론을 참고하여 검토했다. 또한 본 연구에서는 이야기가 흘러감에 따라 변화하는 정보-인물 간 관계, 사실 정보-들을 고려하였다. 작가는 이야기가 흘러가는 매 순간 모든 이야기 속의 사실을 알고 있지만, 독자와 이야기 속의 등장 인물들은 이야기가 흘러감에 따라 작가가 의도하는 순서와 방식으로 사실 정보들을 하나씩 습득하게 된다. 이러한 데이터를 수집/관리하고, 다시 변형하고, 또 유지/보수하는 것이 작가에게 가장 큰 인지적인 부담이기 때문에 이를 지원하도록 노력했다.

Objective : The purpose of this study was to investigate the effects of virtual reality-based activities of daily living (ADL) training on ADL and rehabilitative motivation in patients with traumatic brain injury. Methods : This study was performed using a pre-post design with seven traumatically brain injured patients. Subjects were subjected to virtual reality-based ADL training for 30 minutes a day, 2 to 3 times a week for 4 weeks. Evaluation was conducted before and after the intervention using the Korean Modified Barthel Index (K-MBI), Cognitive Functional Independence Measure (C-FIM), and Volitional Questionnaire (VQ). Changes before and after intervention were analyzed by Wilcoxon signed-rank test, and correlations were analyzed using Spearman's coefficient. Results : After intervention, patients with traumatic brain injury showed significant improvements in K-MBI (p<.05). There was no significant change in total C-FIM score and VQ score (p>.05). Total C-FIM score correlated significantly with VQ score (p<.05, r=.755). The social cognition domain of C-FIM had a significant correlation with VQ score (p<.05, r=826). Conclusions : Virtual reality-based ADL training can improve ADL performance, but further research is needed to determine whether improvements in social cognition and rehabilitative motivation are possible.

This study is a research study to identify the recognition, experiences, needs of convergence education in occupational therapy students. Therefore, it is intended to provide basic data when developing convergence subjects and non-regular programs within the occupational therapy (department) curriculum. From December 03, 2020, a web questionnaire consisting of 14 questions in 4 areas was distributed over a month, and the data of 130 people were finally analyzed. The results are as follows. First, the recognition and experiences of occupational therapy students in convergence education were low. Second, 57.7% of students recognized that occupational therapy majors need convergence education, and the expected effect of convergence education was 'improvement of occupational therapy job-related knowledge'. Third, it was recognized that 'natural science', 'prosthesis and assistive technology, activity of daily living(ADL)', and 'ADL training' convergence education was necessary for the students of occupational therapy department. The results of this study are expected to be used as basic data in the future development of occupational therapy curriculum and non-regular programs for convergence education. In the future, I think that the demand for convergence education and program development in preparation for the 4th industrial revolution will increase in the occupational therapy curriculum. It is expected that the data of this study will be used meaningfully by professors in charge of occupational therapy education at universities.

The This study aimed at clarifying that the cognitive interpretation code is essential for college students to read the correct culture while discussing the producer's story production system for creative advertising content and the process of interpreting the meaning of advertisers and the formation of principles and beliefs. The production of advertising content aimed at persuasion should first identify anachronistic reason system based on the target audience's perception principle. A concise analysis of the experiment found key clues that confirmed that a sample of the producer's intended story would be inconsistent with the clues of information that a college student could remember. I have tried to organize a semantic analysis tool that combines these key clues and as a tool for reading culture of the right time for college students. As a result, university student inmates were able to identify one side of positive communication: reading a new cognitive symbol culture based on their subjective experience and beliefs, rather than analyzing cross-sectional analysis of the primary language and non-verbal expressions of their advertising contents. In the future, if an advertising content story producer works to identify such a process in advance, it will help persuade inmates.

Analyzing of dependency relation among clauses is one of the most critical parts in parsing Korean sentences because it generates severe ambiguities. To get successful results of analyzing dependency relation, this task has been the target of various machine learning methods including SVM. Especially, kernel methods are usually used to analyze dependency relation and it is reported that they show high performance. This paper proposes an expression and a composit kernel for dependency analysis of Korean clauses. The proposed expression adopts a composite kernel to obtain the similarity among clauses. The composite kernel consists of a parse tree kernel and a liner kernel. A parse tree kernel is used for treating structure information and a liner kernel is applied for using lexical information. the proposed expression is defined as three types. One is a expression of layers in clause, another is relation expression between clause and the other is an expression of inner clause. The experiment is processed by two steps that first is a relation expression between clauses and the second is a expression of inner clauses. The experimental results show that the proposed expression achieves 83.31% of accuracy.
