최근 교육의 경향은 7차 교육과정과 더불어 교수자 중심에서 학습자 중심으로 변화되어 가고 있다. 이와 같은 시대적 흐름은 평가에서도 요구되어 학습자의 창의성이나 문제 해결 능력 등의 고등 사고 기능을 신장시킬 수 있고 수업과정에서 수시로 평가할 수 있는 논술형 수행평가의 중요성이 강조되고 있다. 그러나 기존 시스템들은 대부분 과제해결 위주에 국한되어 있어 논술형 수행평가를 제대로 수행하기에는 미흡하다. 본 논문에서는 논술형 수행평가특성에 맞게 학습활동의 평가가 균형있게 이루어질 수 있고, 학교 교육 현장에서 교사가 효율적이면서 체계적으로 학습자를 평가할 수 있는 인터넷 기반 논술형 수행평가 시스템을 제안하고 구현하였다. 구현된 시스템을 현장에 적용하고 설문을 통해 그 성능을 분석하였다.

SMART home is one of the most popular applications of Internet-of-Things (IoT) technologies, which is expanding in terms of range of applications. SMART home technology provides convenience at home by connecting household appliances to a single network, control, and management. However, many general home appliances do not support the network functions yet; hence, enjoying such convenient technology could be difficult, and it could be expensive in the beginning to build the framework. In addition, even though products with SMART home technologies are purchased, the control systems could differ from device to device. Thus, in this paper, we propose a SMART home framework, called an S-mote that can operate all the IoT functions in a single application by adding an infrared or radio frequency module to general home appliances. The proposed framework is analyzed using four types of performance tests by five evaluators. The results of the experiment show that the SMART home environment was implemented successfully and that it functions appropriately, without any operational issues, with various home appliances, including the latest IoT devices, and even those equipped with an infrared or radio frequency module.

Big data was associated with three key concepts, volume, variety, and velocity. Securities and investment services produce and store a large data of text/numbers. They have also the most data per company on the average in the US. Gartner found that the demand for big data in finance was 25%, which was the highest. Therefore securities and investment companies produce the largest data such as text/numbers, and have the highest demand. And insurance companies and credit card companies are using big data more actively than banking companies in Korea. Researches on the use of big data in securities and investment companies have been found to be insignificant. We surveyed 22 major securities and investment companies in Korea for activating big data. We can see they actively use AI for investment recommend. As for big data of securities and investment companies, we studied open API. Of the major 22 securities and investment companies, only six securities and investment companies are offering open APIs. The user OS is 100% Windows, and the language used is mainly VB, C#, MFC, and Excel provided by Windows. There is a difficulty in real-time analysis and decision making since developers cannot receive data directly using Hadoop, the big data platform. Development manuals are mainly provided on the Web, and only three companies provide as files. The development documentation for the file format is more convenient than web type. In order to activate big data in the securities and investment fields, we found that they should support Linux, and Java, Python, easy-to-view development manuals, videos such as YouTube.

유전자 규정 네트워크 (GRN)에 RNA-시퀀싱 데이터를 활용할 때, 해당 유전자와 환경과의 상호 작용에 의해서 생기는 형질들 중에서 연관성이 높은 유전자로 GRN을 구성하는 것은 상당히 어려운 일이다. 본 연구에서는 Big-Data의 RNA-시퀀싱 자료들로, 지지 벡터 머신 회귀 특징 추출(SVM-RFE) 에 근거하여, 연관성이 높은 유전자(maximum-relevancy)는 추출하고, 연관성이 낮은 유전자(minimum-redundancy)는 제거하는 MRMR 필터 방법을 집중도 의존 정규화(intensity-dependent normalization, DEGSEQ)에 기반 하여 데이터의 정밀성을 높여, 소수 연관성 높은 유전자만 판별해 내는 방법을 사용한다. 제안한 방법은 R 언어 패키지를 사용하여 편리함과 동시에, 다른 기존의 방법을 비교하였을 때, Big-Data의 시간 활용도를 높이면서, 동시에 높은 연관성 있는 유전자만을 잘 추출해 냄을 확인하였다.

This paper intends to evaluate the policies which are considered necessary to enhance the T/S competitiveness of Busan's port, and thereby present suggestions to the government which would best implement the results of this research. This research first raises the claim that the majority of the following four conditions: location of the port, port productivity/service level, status of network with overseas ports, and cost competitiveness, should be satisfied in order to maintain a competitive T/S port. Based on these four conditions, seven policies, which are individually pertinent to the four conditions, have been drawn up for proposal, and they are also analyzed in the survey, where all the eligible samples participate to ensure if they are effective in enhancing the T/S competitiveness of Busan. Proposed important policies are a) Terminal operator integration, b) port infrastructure expansion, c) global carriers owned terminal operation, d) enhancement of national carrier's competitiveness, e) feeder carriers' owned terminal operation in new port, f) institutional support for effective and convenient environments for handling T/S cargo, and g) volume incentive expansion. From the analysis by which all the relevant parties (Carriers, Terminal Operators, Port Authority) are answered, it was found that all the seven policies have relevance in strengthening the transshipment competitiveness of Busan's port. Whereas in the analysis that uses AHP methodology to compare the significance among the different policies, it was found that terminal operator integration has the highest priority in terms of increasing transshipment competitiveness.

Delay on State-Funded Construction Projects (SFCPs) in Dong Thap - a province in Mekong Delta of Vietnam, as many provinces of Vietnam, have caused budget overrun through many recent years. The budget-overrun situations, in turn, have deepened the delay. Identifying critical factors affecting delay SFCPs plays a key role to mitigate negative impact of delay. 134/160 questionnaires were collected from personals working for project owners, consultants, supervisors and contractors in Dong Thap Province. Convenient sampling method was used. EFA was resulted in critical 04 factors with 20 variables caused delay in SFCPs, including: "Project technic, contractor's financial capacity and adjustment role of the government", "Regulation and Policy", "Mutual benefit support and concern between the government and residents", and "Disadvantage of construction site and weather season". Reliable measures to reduce delay on SFCPs are discussed to establish legal corridors to strictly controlling the process, consider mutual benefit between the government and its residents, and evaluating construction conditions. Those measures are considered could be applied in not only Dong Thap province, but most provinces of Vietnam as well.

This research was done to clarify the factors related to sexual satifaction in women who have had a hysterectomy, and to idenify which factors had statistically significant influence of sexual satisfaction of the subjacts. The objective of this study was to identify the variables related to sexual adaptation which might be changed by nursing intervention. This was a cross-sectional descriptive correlation study. There were 230 subjects in the study, and they were selected by a convenient sampling method. The tool. for this study was developed by the researcher through modification of the Dergatis Sexual Function Inventory(DSFI). A pilot study was done to determine the necessary modifications. Data collection was done between Sept. 1987 and Du. 1987 using a mailed questionnaire. The characteristics of the subjects were as follows : The mean age of the subjects was 42.3 years and 204(87.4%) of the subjects had nine or more years of education. The mean income of the subjects was 85.8870 won / month, and 179(77%) of them were housewives. The mean number of pregnancies and children were 4.9 and 2.5 respectively. Oophorectomies were included in the surgery for 66(28.7%) of the subjects. Only 12(5.2%) were planning to have more children. Only 88(38.3%) of the subjects had received information prior to the surgery regarding health problems related to the operation and less than half, 111 (48.3%), had received this kind of information before discharge. Lay persons were the source of information about the post-operation status for 196 (85.2%) of the subjects, but the content of the information did not significantly influence the sexual satisfaction score. Only 16(7.0%) of the subjects said they regretted having a hysterctomy while 102(44.3%) said they were pleased to have had a hysterectomy. Ninety (39.1 %) of the subjects reported that their husbands had “stress” and 164(71.3%) of the subjects reported “stress”. The results of this study are summarized as follows : 1. The mean score for sexual satisfaction of the subjects was 34.24 with a possible maximum score of 50.00. Eighty two(35.8%) were responded that they were satisfied with their sexual life but 61 (26.5%) were responded that they were dissatisfied with their sexual life 2. The following 15 factors extracted from the results of the data analysis were significantly related to sexual satisfaction(p＜.05) ; support of husband, body image, emotion, knowledge of sex, menopausal symptoms, sexual behavior, the feelings the subjects had about the hysterectomy, stress for both subject and husband, the number of children, health information given before operation, job, age, level of education and income. The five most important factors influencing sexual satisfaction were identified by using stepwise multiple regression analysis. The most important factor was support of husband, which explained 17.83% of the total variance. The remaining factors in order of significance were : Knowledge of sex, income, job, and emotional status. Those five factors explained 35.16% of the sexual satisfaction. In conclusion, for the care of women who are going to be discharged from hospital after having had a hysterctomy, nurses have to work with the husbands to help them to understand the importance of their support. Nurses also need to make sure that the subjects have an adequeate knowledge of sexual life after a hysterectomy. Also nursing interventions should focus on subjects who do not have a job, who are of low economic status, and the subjects who are under the unpleasant mood.
