  • Semiconductor industry has been taking the advantage of improvements in process technology in order to maintain reduced device geometries and stringent performance specifications. This results in semiconductor manufacturing processes became hundreds in sequence, it is continuously expected to be increased. This may in turn reduce the yield. With a large amount of investment at stake, this motivates tighter process control and fault diagnosis. The continuous improvement in semiconductor industry demands advancements in process control and monitoring to the same degree. Any fault in the process must be detected and classified with a high degree of precision, and it is desired to be diagnosed if possible. The detected abnormality in the system is then classified to locate the source of the variation. The performance of a fault detection system is directly reflected in the yield. Therefore a highly capable fault detection system is always desirable. In this research, time series modeling of the data from an etch equipment has been investigated for the ultimate purpose of fault diagnosis. The tool data consisted of number of different parameters each being recorded at fixed time points. As the data had been collected for a number of runs, it was not synchronized due to variable delays and offsets in data acquisition system and networks. The data was then synchronized using a variant of Dynamic Time Warping (DTW) algorithm. The AutoRegressive Integrated Moving Average (ARIMA) model was then applied on the synchronized data. The ARIMA model combines both the Autoregressive model and the Moving Average model to relate the present value of the time series to its past values. As the new values of parameters are received from the equipment, the model uses them and the previous ones to provide predictions of one step ahead for each parameter. The statistical comparison of these predictions with the actual values, gives us the each parameter's probability of fault, at each time point and (once a run gets finished) for each run. This work will be extended by applying a suitable probability generating function and combining the probabilities of different parameters using Dempster-Shafer Theory (DST). DST provides a way to combine evidence that is available from different sources and gives a joint degree of belief in a hypothesis. This will give us a combined belief of fault in the process with a high precision.

  • The purpose of this study was to examine nurses’ perceptions of medication treatment for psychiatric patients and to compare these perceptions with the perceptions held by the patients. The methodology used in this study was a descriptive design with semi-structured and open-ended interviews. This study used a convenience sample of 112 nurses who worked in, and 209 patients who were under psychiatric treatment, in four hospitals attached to a university and one national mental hospital in the city of Seoul. The collected data were analyzed by SAS, using percentages for descriptive purposes, and t-test or x$^2$ for comparing the variables. The results were as follows : 1. There was no significant differences between nurses’ and patients’ perceptions on the extent to which patients complied with their medication treatment. Generally speaking, the mean compliance scores for both nurses and patients was high(nurse : (equation omitted)=3.70, Patient : (equation omitted)=3.76). 2. There was a significant difference in nurses’ and patients’ perceptions on the reasons why patients do not take medication. The nurse group indicated that the patients did not take medication because of the “worry about side effects or habituation(49.53%)”, “boredom from long-term use of medication(26.17%)” and “distrust toward medical staff(12.15% )”, but the patient group indicated that they “did not want to be dependent on medication (25%)”, “forgot to take medication(19.7%) and “worried about side effects or habituation(15.91%). 3. As for the necessity of medication, both groups showed some different responses. Even though both groups were aware of the necessity of taking medication, the patient group(21.53%) showed a more negative response. As (or the effects of medication, both groups (nurses and patients ) showed positive responses. However, the nurse group showed a higher positive response (91.07% ) than the patient group(74.16%), 5. Both the patient and nurse group indicated that the most helpful element for the patient’s life under psychiatric treatment was interviews and conversations with therapists and nurses. However, the nurse group showed a higher response(70.15%) than the patients group(47.15%). According to the patient group, family support for the patient was another important factor for psychiatric treatment and daily struggles. In conclusion, as there were differences between the perception of nurses and patients, the nurse must consider the patients’ subjective perceptions first. They should also revaluate their false belief and prejudice concerning the patients’ perceptions. Such information can provide a base to be applied by the nurses in devloping effective mutual relationships with patients which can in turn help in compliance with medication regimen. As it was confirmed that medication was the most important factor in the patients’ recovery, a thorough education program on the therapeutic effect of medication and the necessity of their continued use after discharge is also needed.

  • 본 연구는 우리나라 195개의 기업을 대상으로 세계적으로 관심의 대상이 되고 있는 노동시장의 유연성 전략 즉 수량적 유연성과 기능적 유연성이 조직의 결과변수인 생산성, 노사협력성, 고용안정 등에 어떠한 영향을 주는가를 기업 단위로 분석하였다. 또한 노동시장 유연성(수량적 유연성 및 기능적 유연성)과 노사협력성 및 고용안정간의 관계에서 노조 힘의 조절역할에 대해서도 분석하였다. 결과는 수량적 유연성은 생산성, 노사협력성, 고용안정 등과 유의한 관계를 보여주지 않았으나 기능적 유연성은 생산성, 노사협력성, 고용안정 등에 상당한 정의관계를 보여 주었다. 이러한 결과는 기업의 노동시장 전략에서 기능적 유연성의 중요성을 다시 확인할 수 있다. 서구에서는 기능적 유연성의 중요성을 지속적으로 주장하고 수량적 유연성의 문제점을 지적하고 있다. 그러나 본 연구에서는 기능적 유연성의 긍정적 측면은 확인이 되었으나 수량적 유연성의 부정적 관계가 확인될 수 없었다는 점에서 이들 관계는 앞으로 좀 더 연구가 지속되어야 하는 과제도 남겼다. 노동시장 유연성과 노사협력 및 고용안정과의 관계에서 노조 힘의 조절역할에 대한 분석결과는 수량적 유연성과 노사협력성 관계에서만 노조 힘의 상호작용 효과가 확인되었다. 이러한 결과는 노조의 기회주의적 행동에 대한 가능성을 엿볼 수 있다. 이러한 결과에 대한 논의를 할 것이다.

  • 현재 대한민국의 의료 기술과 의료 서비스는 세계 어디에서도 뒤처지지 않을 정도로 세계적인 수준을 자랑하고 있다. 하지만 이러한 의료서비스는 아직까지 환자중심이 아닌 병원 또는 의료진을 중심으로 이루어져 있으며 조금씩 환자 중심의 의료 서비스로 변화하고 있는 추세이다. 한국보건사회 연구원의 조사 결과에 따르면 2016년 현재 병원 입원 환자 중 30%이상이 회진과 관련된 정보를 충분히 제공받지 못했고 특히 2~30대 환자의 50%이상이 불만을 표시 하였고 70대 이상에서는 17% 정도가 불만을 표시 했다고 한다. 이러한 자료를 비추어 볼 때 특히 2~30대가 회진등과 관련된 정보를 바라고 있으며 이들은 스마트 폰 사용에 익숙하다는 특징을 고려하여 회진정보 스마트 폰 애플리케이션을 설계 구현하고자 한다. 현재 일부 중 대형 병원에서는 스마트 폰 애플리케이션을 통해서 병원 정보를 제공하고 있으나 병원 안내 또는 외래환자의 진료 예약 등이 주요 목적이며 회진 정보를 제공하는 경우에도 대략적인 회진 시간만을 제공하고 있다. 본 논문에서는 스마트 폰에 있는 NFC 기능을 활용해서 회진 시 자신의 순서를 확인할 수 있는 병원 회진 안내 시스템을 설계 및 구현 하고자 한다.

  • Kim, Jun-Geun(Gisan) was a late 19th century Chosen dynasty painter who created numerous genre paintings for West European clients in the newly opened treaty ports of Wonsan, Busan and Inchon. The treaty ports in the late 19th century Chosen represented of the crossroads the economy, values, and the institutions of the West European powers. In particular, the agriculture-based economy, Confucianism, and land-owner noble class started being eroded by a commerce-based economy, the values of Christianity, West European institution, and a new class of people who amassed wealth from commerce. As Kim, Jun-Geun's paintings were created for sale to West European clients, they exhibit characteristics that are distinct from the traditional genre paintings in terms of presentation style and the selection of the subject matters. The export genre painting originated in the 18th century around Guangdong, China. Broadly, there are two styles of genre paintings: the Guangzhou style and Ningbo style. Kim, Jun-Geun's paintings resemble the Ningbo style. The Ningbo style tends to highlight the main subjects, form an album of small paintings, and provide a simple treatment of the scenes without the background. Kim, Jun-Geun's paintings cover most aspects of life of common people of his time, ranging well beyond the subjects matters of the traditional genre paintings. His subject matters include the scenes of funeral, folk games, Buddhist and ancestor worship, prison and punishment, shaman custom, debauchees, government officials' formal trips, beggars and handicapped, etc. Many of the subjects are the neglected and the oppressed of the society. And he presents in detail the dress and its ornament that the subjects wear, and all the utensils and things around them. Besides, his subjects' faces are generally expressionless, and their postures are stiff; as such, the feeling of liveliness or movement is lacking. It may be the results of Kim, Jun-Geun's taking the other perspective, namely of his West European clients, rather than his own. The adoption of the other perspective may in turn be a product of the Social Darwinism and the new sense of values that accompanied the infusion of Christianity and West European institutions. Kim, Jun-Geun's portrayals of his subjects appear to reflect the attributes with which the West European Orientalists' of the period characterized the people of the Far East, namely, backwardness, barbarity, irrationality, violence, and mysticism.

  • Yangbanxi("model plays") symbolize the Cultural Revolution(1966~1976) in China. The Eight Model Revolutionary Works include five Chinese Modern Peking Operas, namely, Taking Tiger Mountain by Strategy(智取威虎山), Harbor(海港), Shaijabang(沙家浜), The Red Lantern(紅燈記), and Raid on the White Tiger Regiment ; (奇襲白虎團), ballets such as The Red Detachment of Women(紅色娘子軍) and The White-Haired Girl(白毛女) ; and a symphony: Shajiabang(沙家浜). On April 24, 1967, Chinese leaders, including Mao Zedong, saw a performance of The White-Haired Girl. Yanbanxi was performed in Beijing between May 24 and June 15 the same year. The Red Lantern was designated as a work for the proletarian classes by Jiang Qing(Mao Zedong's third wife and the most influential woman in China) and spread nationwide. It was also made into a film to be enjoyed by many people. The modern Chinese operas went a long way in their creation of visual images of revolutionary heroes. The Red Lantern, in particular, came to be regarded as the most representative revolutionary opera. In the course of such a process, Jiang Qing used Yangbanxi as a political tool for compelling the people to worship and pledge their allegiance to Mao in an effort to turn the Cultural Revolution into a class struggle on behalf of her husband. During the Cultural Revolution period, artists were made to associate with workers, farmers and soldiers based on the idea of advocating revolutionary arts for the proletarian classes. The characters in The Rend Lantern were portrayed as heroes from the proletarian classes according to the demands of the era. Chinese leaders set forth the principles of artistic expression, stressing three important factors: politics, heroes, and heroic acts, which were to be applied to all the visual arts, including Yangbanxi. This paper attempts to present a new view of fine arts during the Cultural Revolution in China by focusing on the productive significance of a leading style of a specific era in the past. To that end, this paper sheds light on products made in conformance with political instructions, stressing the importance of revolutionary heroes in The Red Lantern.

  • 밀집이 심한 도시는 불투수 면적이 많아 흘러나온 빗물이 빠르게 도로를 타고 한쪽으로 모이게 된다. 이는 도로에 설치된 빗물받이로 차집이 되지 못한 많은 노면 유출수로 인해 측구에서의 흐름 폭이 넓어져 정체 노면수를 증가시켜 교통체증과 미끄러움으로 인한 사고를 유발한다. 이에 본 연구에서는 차집유량 산정식을 제시하기 위해서 간선도로와 고속도로의 최대 종경사를 반영하여 2~10 %의 도로 조건을 반영하였고, 측구 횡경사는 일반도로 횡경사인 2 %를 선정하였다. 도로 차선조건은 중앙차선과 보도를 경계를 2, 3, 4 차선을 선정하였으며, 실험유량은 설계 빈도 상황을 고려하여 실제 도로 조건의 5년, 10년, 20년, 30년의 설계빈도 유수유출량을 실험유량으로 환산한 결과 1.36 l/s~3.96 l/s의 유량을 10개로 나누어 수리실험을 진행하였다. 또한, 측구로 들어오는 유입유속과, 흐름 폭을 고려한 식을 제시하였다. 실험 결과 종경사 증가에 따라 흐름 폭은 증가하고, 차집율은 감소하는 경향을 보였다. 이에 본 연구에서는 IBM SPSS Statistics 24 프로그램으로 회귀분석하여 설계빈도에 따른 우수 유출량, 도로의 종경사를 반영한 흐름 폭과 유입유속의 빗물받이 차집유량 산정식을 도출하였다. 산정된 도출식은 도로에서의 빗물받이 설계에 기초자료로 활용될 것으로 판단된다.

  • 본 연구의 목적은 고경력의 한 초등학교 교사의 생애사를 살펴보고 그의 생애 과정 동안 일어난 과학 수업의 변화 양상을 이해하는 것이었다. 연구 참여자인 박 교사와의 생애사 면담 및 생애사 자료를 바탕으로 생애 이야기를 작성하고, 박 교사의 생애 동안 어떤 외부 요인과 개인 요인의 상호 관계 속에서 과학 수업이 변해 왔는지 그 양상을 시기별로 나누어 분석하였다. 연구의 결과로서 수업 변화기 I에서는 박 교사가 외부 요인의 영향을 적극적으로 수용하여 수업을 변화시킴으로써 학생 중심의 과학 수업에 대한 전문성의 싹을 틔웠음을 알 수 있었다. 반면, 수업 변화기 II에는 박 교사가 외부 요인에 의한 수업 변화 흐름에 비판적으로 대응하면서 자신만의 수업 방식을 다져 나갔다. 마지막으로 수업 변화기 III에서는 박 교사가 자신의 개인 요인에 의해 외부 요인의 영향을 긍정적인 것으로 전환하면서 수업 변화를 이루었다. 이러한 결과를 토대로 수업 변화를 위해서는 교사의 생애 주기와 전문성의 정도를 고려한 정책이 필요하며 교육 변화와 관련된 요인들에 대한 교사들의 성찰과 전환 노력이 있어야 함을 제안하였다.

  • 항공산업의 발전에 따라 국제적으로 운항승무원의 피로 위험 관리에 대한 중요성은 증가하고 있으며, 이와 관련한 피로도 연구와 법 제정은 전 세계적으로 활발하게 진행되고 있다. 이미 미국, 유럽 등의 비행 선진국은 비행시간과 비행근무시간 규정을 운항 승무원의 출두 시간, 이착륙 횟수, 휴식시간, 시차적응상태 등의 비행 환경을 반영한 최대 비행근무시간을 유연하게 적용 운항승무원의 피로도를 관리하고 있다. 국내의 경우는 운항승무원의 비행 환경 및 비행 조건을 반영하지 않은 연속되는 일간, 월간, 연간 기준으로 최대 비행근무시간을 정하는 획일적인 방식을 적용하고 있는 실정으로, 피로 위험관리시스템의 개선이 필요한 시점이다. 하지만 선진 해외항공사 위주로 개발된 피로도 관련 법과 규정을 국내의 비행 환경을 고려하지 않고 적용할 시 부작용이 있을 수 있다. 본연구의 국내 운항승무원 피로도 관련 설문 조사 결과에 의하면, 이미 해외에서 적용하고 있는 최대 비행시간 규정을 수정 없이 그대로 국내에 도입 및 적용하는 경우, 오히려 국내 운항승무원의 피로도는 증가할 수 있다는 시사점을 도출하였다. 이에 국내의 비행 환경과 문화에 적합한 한국형 비행근무시간 제한에 관한 연구의 필요성을 제안하고자 한다.

  • The global process of transition from industrial to information society, as well as socio-economic changes taking place in Ukraine, require significant changes in many areas of state activity. It is especially connected with the reforms in the sphere of education. Today, national programs provide for the development of education on the basis of new progressive concepts, the introduction of the educational process of new pedagogical technologies and scientific achievements, the creation of a new system of information education, entrance of Ukaine into the transcontinental computer information system. Information technologies are qualitatively changing the key resources of development: this is no longer a space with fixed production, but primarily mobile finance and intelligence. They have a direct impact on the formation of personal growth, professional content and self-organization, emotional and psychological maturity and consciousness, and so on. One of the main factors in ensuring the stability and social education of the country's citizens is the culture of security, the formation and development of which is an urgent problem today. Comprehensive and systematic development of security culture will significantly increase the readiness of the population, the level of environmental, labor and patriotic education, reduce human losses, material damage from emergencies. Ecological education can be carried out more successfully only gradually and in accordance with the socio-psychological periods of one's development: kindergarten - school - college - university. The creation of such a system of environmental education should be enshrined as the basis of state environmental policy as a constitutional norm with the usage of information technology. Graduates of universities, who are the future of our country, after mastering the skills of basic environmental education must have a high level of environmental culture, which is, in turn, part of general human culture, and investigate environmental issues from the standpoint of their profession. It is known that with the help of environmental education the collective intelligence of society is formed, which can predict human activities and processes occurring in nature, and in some way to help with the elimination of crises. It is through environmental education that another system of human values is being formed, which places great emphasis on intangible wealth and solidarity, and great responsibility of humanity for the ecological state of the native country; provides a higher standard of living as a result of sustainable development, through the introduction of information technology in this system. To improve the quality of life, we need better knowledge, which must be implemented through information technology at the international level.
