  • 데스크탑 그리드(Desktop Grid) 환경에서는 자원 제공자인 데스크탑의 자율적 연산 참여와 탈퇴를 허용하기 때문에 기존 데스크탑 그리드 시스템들은 연산 도중 잦은 중단으로 인해 연산의 완료 시간이 지연되고, 연산 수행의 신뢰성이 저하되며 연산의 완료를 보장하지 못하고 있다. 기존의 데스크탑 그리드 시스템들은 이러한 데스크탑의 동적 특성을 반영하지 못하고 있을 뿐만 아니라 데스크탑의 연산 수행 양식을 고려하지 않아 시스템의 안정성과 성능이 저하되었다. 신뢰성 높은 연산 수행을 지원하고, 데스크탑의 비예측적 연산 수행 속성을 극복하기 위해서는 데스크탑의 동적인 특성인 휘발성(volatility)을 고려한 스케줄링이 필요하다. 본 논문에서는 휴리스틱 접근을 통해 동적으로 가변하는 데스크탑의 상태를 보다 정확하게 모델링 하는 가용성 기반 마코브 작업 스케줄링 기법을 제안한다. 제안 기법은 데스크탑의 가용성을 기반으로 과거 연산 수행에 대한 패턴을 확률 모델링하여 미래 연산 수행 유형을 예측함으로써 연산 수행 도중의 불안정한 자원 제공 현상을 완화시키며 안정적인 스케줄링을 지원하여 시스템의 신뢰성과 성능을 향상시킨다.

  • COVID-19 pandemic has made the economy in Indonesia sluggish, especially Small and Medium Enterprises (SMEs). Simultaneously, the SMEs existence in Indonesia is fundamental and considered important by the government since it is able to assist numerous laborers and become an income source for the lower and middle classes of the community. The productivity of SME in a region will undeniably influence the availability of job and, of course, reduce the number of unemployed. Therefore, in this study, the researchers looked at how to improve SMEs performance to continue to exist amid the COVID-19 pandemic, by identifying the relationships between product characteristics, market competitive strategies, and the performance of SMEs. The research was done on SMEs in West Java, Indonesia. The example employed was Batik SMEs in Cirebon with at least 10 years in existence, and the total number of these SMEs was 165. As the basis of a quantitative approach, this study employed survey instruments by distributing a questionnaire. In analyzing the data, it utilized the structural equation modeling (SEM). The result showed a significant relationship between Product Characteristics, Market Competitive Strategy, and Price and Product Success Rate on SMEs Performance. This study's findings contribute to the SMEs performance literature.

  • The study determined the access, skills and constraints towards the usage of ICT among barangay officials. A complete enumeration technique was used due to the small size of the population. A total of 121 barangay secretaries and barangay treasurers comprised the study respondents. The findings revealed that most of barangay officials have access to personal computer at home and in the office using their own mobile data and office internet connectivity. With the support from the Local Government Unit (LGU), it was found that most of the respondents are advance and proficient in computer usage. As constraints to ICT usage, the study respondents still experienced slow internet bandwidth that makes connection and communication weak along with the low income status. Consequently, it was found that there were no significant differences in terms of skills and constraints among barangay secretaries and barangay treasurers towards using ICT. It can be concluded that study respondents prefer to use office computer to access the information they need due to the convenience and availability of resources. The study respondents were competent enough to handle their job well but listed slow internet and low financial resources may hamper their ICT usage. Research implications were also offered.

  • Interest in the Quality of working life is spreading rapidly and the phrase has entered the popular vocabulary. That this should be so is probably due in large measure to changes in the values of society, nowadays accelerated as never before by the concerns and demands of younger people. But however topical the concept has become, there is very little agreement on its definition. Rather, the term appears to have become a kind of depository for a variety of sometimes contradictory meanings attributed to it by different groups. A list of all the elements it if held to cover would include availability and security of employment, adaquate income, safe and pleasant physical working conditions, reasonable hours of work, equitable treatment and democracy in the workplace, the possibility of self-development, control over one's work, a sense of pride in craftsmanship or product, wider career choices, and flexibility in matters such as the time of starting work, the number of working days in the week, Job sharing and so on altogether an array that encompasses a variety of traditional aspirations and many new ones reflecting the entry into the post industrial era. The term "quality of working life" was introduced by professor Louis E. Davis and his colleagues in the late 1960s to call attention to the prevailing and needlessly poor quality of life at the workplace. In their usage it referred to the quality of the relationship between the worker and his working environment as a whole, and was intended to emphasize the human dimension so often forgotten among the technical and economic factors in job design. Treating workers as if they were elements or cogs in the production process is not only an affront to the dignity of human life, but is also a serious underestimation of the human capabilities needed to operate more advanced technologies. When tasks demand high levels of vigilence, technical problem-solving skills, self initiated behavior, and social and communication skills. it is imperative that our concepts of man be of requisite complexity. Our aim is not just to protect the worker's life and health but to give them an informal interest in their job and opportunity to express their views and exercise control over everything that affects their working life. Certainly, so far as his work is concerned, a man must feel better protected but he must also have a greater feeling of freedom and responsibility. Something parallel but wholly different if happening in Europe, industrial democracy. What has happened in Europe has been discrete, fixed, finalized, and legalized. Those developing centuries driving toward industrialization like R.O.K, shall have to bear in mind the human complexity in processing and designing the work and its environment. Increasing attention is needed to the contradiction between autocratic rule at the workplace and democratic rights in society.n society.

  • Objectives: Exposure assessment using questionnaires is effective in large-scale epidemiological studies. However, a limited number of studies have evaluated the questionnaires used in epidemiologic studies in terms of occupational and environmental exposure. The purpose of this study was to summarize and evaluate questionnaire items included in major epidemiological studies conducted in Korea with regard to occupational and environmental exposure. Methods: A total of 12 studies (four cohort studies, six large-scale cross-sectional surveys, and two panel studies) were selected for this study. Various questionnaire items related with occupational and environmental items were collected and summarized into tables. Results: Although job type and address were included in almost all of the studies, the information on occupational or environmental exposure to specific risk factors was collected in a limited number of studies. Moreover, questionnaire items were not standardized, warranting a continuous effort to develop questionnaires and evaluate their validity. Conclusion: Our results suggest that validated questionnaire items focusing on occupational and environmental exposure need to be developed in order to enhance the availability of the information collected from questions in epidemiological studies.

  • The purpose of this study is to examine how the perception of lives and studies in the Joseon Dynasty period, and the concept of its sculptures can be reflected in Korean traditional pavilion place, from the perspective of Nomadism as a western philosophy of this era. Nomadism literally refers to way of life of peoples who do not live continually in the same place but move cyclically searching for temporary centres whose stability depends on the availability of food and water supply or pastures for their livestock. In recent years, the term encompasses three general types: job nomads, digital nomads and ubi-nomads, which represent distinct features of modern society. Its concept implies looking for the new creative possibility through the liberation of desire and the breakaway to another thinking through continuous formation and transformation. Likewise, Korean traditional pavilion is the architecture to take a quick rest while walking in the mountains. This open place thus connects surroundings with people who are allowed to assimilate with nature as well as train their mind by following the law of nature, in order to finally reach the celestial state of mind. Knowing how to see, enjoy and appreciate the arts very close to nature, our ancestors were able to learn aesthetic activities. After recognizing Korean traditional pavilion as the potential place of unification of heaven and men which is Korean scholor's lifestyle and outlook on the world, this study accordingly will identify the value and meaning of Korean traditional architecture according to Nomadism in the occidental point of view.
