The proliferation of devices such as tablets and smart phones, which are now used by many people in their daily lives, has led to a number of companies allowing employees to bring their own devices to work due to perceived productivity gains and cost savings. However, despite many advantage, security breaches (e.g., information leakage) can happen for various reasons (e.g., loss or theft of devices, and malicious code) and privacy breaches can happen by using personal devices for business. We should carefully scrutinize security threats in this area. We present the security threats analysis and the technical approach in this area, and discuss privacy threats and countermeasures.

Formwork layout is perceived as important due to its strong tie to site works. But, most formwork is done manually and influenced by worker's skill and thus, a lot of construction errors occur. The introduction of BIM (Building Information Modeling) enables acquiring more precise information on the building shape, dimension, structure, etc. than 2D-based drawings and thus, the increased productivity, such as reduction of workload and work times, and the economic efficiency, such as reduction of formwork types and form dimensions with the consideration of constructability, are expected. This study reviewed the previous studies and formwork layout systems to derive this study's differentiations and factors to be first considered for formwork planning were derived by analyzing priorities against consideration factors. Last, a flow chart and algorithm were developed to apply the derived factors to the formwork layout module.

These days the use of personal computer has become generalized at factory, office, house, etc and this fact indicates that visual display terminal work became popular in every field of our society. The use of computer improves work efficiency, productivity & qualify but in addition, it also generated the physical and mental diseases or defects so called VDT syndrome to workers. The purpose of this paper is to analyse the computer-work-related anti-physical, anti-psychogenic symptoms & side effects through the data drawn from workers who use computers on their works, and to find out methods of improvement & humanization of computer works. The follows are the results of questions about personal sensibility of VDT syndrome. 1. Female workers are more sensitive to the side effects of computer labor than males. 2. Workers aged twenties feel more severe symptoms of VDT syndrome than thirties or fourties, but there are no level of significance. 3. Middle managements workers are the most sensitive group to VDT syndrome, on the other hand tow managements are less sensitive than operators. 4. The result of questions indicates that a phone conductress show more severe VDT syndrome symptoms than business affairs or an engineer workers, with level of significance. 5. The longer computer work engagement period, the more evident VDT syndrome symptoms appear. For instance, workers who have more than 2 year engagement period complain more severe symptoms, compared workers who have less than 2 year engagement period. 6. Long computer working time per day also increases VDT syndrome severity specially people who have more than 2 hours in working time in a day have much less severe symptoms, compared people whose daily working time exceeds 2 hours. 7. Specific body part which shows VDT syndrome symptoms is shoulder, wrist, neck, finger, eye, waist, arm in the order of severity. 8. Sensibility of VDT syndrome symptoms have effect on degree of vocational satisfaction.

Purpose - Average using time of smart-phone for Korean people is 3 hours 39 minutes and most people who are using a computer at home and their workplace can be affected over force to neck and shoulder due to unstable body posture. musculoskeletal disorders which caused by unstable body posture can affect strongly to decrease work efficiency. So this research is designed to measure the effect of using computer & smart-phone on decreased work efficiency due to musculoskeletal disorders and mediating effect between decreased work efficiency and musculoskeletal disorders. Research Design, Data, and Methodology - The author has developed a questionnaire with 6 hypothesis on the basis of previous research result with 5 constructs. The questionnaires were also made by interview and E-mail. 300 copies of questionnaires were distributed and 282 questionnaire were used for the analysis as valid data responses. SPSS ver.21.0 were used and made Cronbach's α and reliability test, correlation, Baron & Kenny 3 step mediated regression analysis. Result - Cronbach's α shows 0.770~0.954 and C.R. is 0.963~0.997 which is higher than 0.7. and AVE was 0.867~0.933. So the data are all acceptable condition. Using for a long time of a computer & smart-phone has a positive effect on musculoskeletal disorders. This means, it can cause musculoskeletal disorders if people use a computer & smart-phone for a long time due to unstable body posture. And musculoskeletal disorders can effect strongly decrease work efficiency. This study also found out that a long time of using computer can cause musculoskeletal disorders rather than using smart-phone a long time. To check mediate effect of musculoskeletal disorders between using a computer & smart-phone and Decreased Work Efficiency, author used 3-step mediated regression analysis of Baron & Kenny (1986). Using a computer for a long time mediate partially and using a smart-phone for a long time mediate completely. This means that using a smart-phone a long time is not the actual reason to decrease work efficiency. But using level of smart-phone is increasing rapidly day by day. So we need to make additional research about this matter seriously. Conclusion - Nowadays, people can not live on without a computer & smart-phone even a moment. But, using a computer for a long time will affect to cause musculoskeletal disorders and it will effect strongly to decrease work efficiency. Before, we thought over that musculoskeletal disorders were diseases of elder people. But, we found out from this study that musculoskeletal disorders can be happen to any people, even children, or workers in heavy industry or engaged in brain work. So we need to be careful when we use a computer for a long time. People also need to be careful to keep correct body posture when using both a computer and smart-phone since a smart-phone became more popular and using time level became longer. Due to increased income and living standard of people, physical growth of young people is so rapid. But the physical environment of society is not suitable for them since it can not follow up the speed of growth. Suitable work table is very important to prevent musculoskeletal disorder which can affect decrease work efficiency. For a person, a society or country, increased productivity is very important since it can directly connected to the job satisfaction. Education and reeducation for the people is also important, but to teach them how to keep good condition of health will be more important since it can increase the quality of work efficiency and quality of life. Computer and Smart-phone is one the best invention of modern society, but it can cause mental and physical disease which can affect decrease work efficiency and productivity. So it is necessary to observe attentively for the situation continually.

ISO9000 set of standards has been widely applied in Iranian Automotive manufacturing industry. Regarding the effects of TQM and ISO9000 set of standards various studies have been conducted and different quantitative conclusions have been made. Due to lack of quantitative information, in many of the cases, using qualitative information becomes the best option. The qualitative nature of data in such cases, requires qualitative analysis methods that might lead to some challenging computational issues. This paper examines the impact of ISO9000: 2000 certification and its perceived benefits for an automotive manufacturing company. Using an empirical approach, the paper seeks to ascertain if certification has indeed improved the performance of the company. Our null hypothesis rotates around the effect of ISO9000: 2000 on the 4W's of an enterprise. To carry out the research, first we developed a couple of questionnaires including all criteria of ISO9000 and 4W's. Second, the questionnaires were discussed with two researchers knowledgeable in the field, and then submitted to the quality practitioners and executives of Iran Khodro Enterprise-a leading company in Iranian automotive manufacturing industry. Finally the null hypothesis was tested and the technology improvement dimensions were ranked through nonparametric tests. The results illustrated a reasonable cause and effect relationship, suggesting that ISO9000: 2000 has positive effect on the 4W's of company result. In this work we investigate the effect as technology improvement viz., the improvement of techno-ware, human-ware, info-ware, and organ-ware.

The concepts of interior design work have set forward an aesthetic and functional proposition to be answered by those who design spaces. The available range of suitable materials for interior use appears to be almost inexhaustible in this day and age. Now a day, relatively new fields of study on environmental-friendly interior examine humans'innate affinity for health and explore its implications for architecture and the built environment. A growing field of research suggests that spaces' relationship to aesthetics and environment can either help or hinder their occupants' health and wellness, productivity, and even their creativity. This paper presents several examples of already built apartment houses in practice, and discusses the demand of users of the spaces for health and sustainable environment, deepening the relationship between newly-constructed spaces and the remodeled ones. The considerations to some new and contemporary materials from the aspect of healthy indoor architecture design are presented in this paper. Designers need to rethink the conventional and high-tech interior environment in apartment houses with respect to perceived air quality, material emissions, and odors. The future of interior design is oriented on light shapeable materials which are able to create a unique memorable atmosphere. The primary assignment in accepting recent materials and proceedings is our responsibility to creating proposals, that are mainly safe, hygienic and environmentally proper.

This exploratory study investigated the software programs utilized by clinical dietitians and their perceptions on the use of information technology. The study focused on the use of specialized software for dietetics, general software for any office use and the Internet. A self-administered survey was used to collect data from clinical dietitians identified in the Kentucky Dietetic Association Directory 2003-2004. The survey was conducted in March through April, 2004. A total of 22 responses were collected, which yielded a response rate of $68\%$. Findings suggest that computer use has become a routine for optimal clinical practice ; major specialized software programs are used for nutrition assessment, nutrition analysis and menu development. Use of specialized software appears to be unassociated with dietitians' age and years of experience ; however, the associations are indicated between use of specialized software and education level as well as their specialty ; word processing and spreadsheet are the major general software used. Internet is used mainly for information search and communication. Respondents perceived that overall work efficiency and productivity significantly increased with computer use. The complexity of software is the major barrier encountered so training is the most needed support by the department. Strategic promotion on the use of specialized software should be targeted to the management team of the hospitals/facilities.

본 연구는 수도권의 인구 고령화 현상을 예견하면서 향후 사회복지 정책과 서비스를 계획하고 구체적인 복지 서비스 기관과 시설을 재편성하는 기초 자료를 마련할 목적으로 시행되었다. 수도권 3개 지역에 거주하는 40대에서 80대까지의 30명을 표본으로 선정하여 심층적 면접을 통해 노후생활에 대한 인식과 노인에 대한 인식을 살펴보았다. 경제적 측면에서 노인에 대한 부정적 고정관념(ageism)으로 노인에게 취업의 기회가 잘 주어 지지 않는 것은 물론 노인 스스로도 능력이 떨어진다거나 능력이 없다고 판단하는 경우가 많은 것으로 나타났다. 그리고 이러한 중년층과 노년층 사이에도 큰 차이를 보이지 않았다. 사회적 측면에서는 중년층 및 노년층 모두 별 차이 없이 사회 참여도가 낮았고, 노년층의 경우 일상생활 일과에서 특별한 목표가 없고 규칙적이지도 못하고 계획도 거의 없는 편이었다. 심리사회적 측면에서는 중년기 이후 세대들은 세대 간의 큰 차이 없이 아직도 가족, 이웃과 사회에서 소외되었다고 느끼지 않았다. 복지 서비스 측면에서도 중년층과 노년층 큰 차이 없이 모두 소득보장, 의료보장, 주거보장 등의 기본적인 서비스를 필요로 하고 있었고, 사회 서비스가 부족하다고 인식하고 있었으며, 특히 원하는 사회 서비스를 받기 위해서는 1 시간 이상의 이동도 가능하다고 했다. 중년층과 노년층 모두 노후준비의 필요성과 시의성에 대해 동의하지만 사회복지제도의 미흡과 자녀 양육 및 교육 때문에 실제적 준비를 할 수 없거나 할 수 없었다고 했다. 노후생활에 대한 인식에서는 중년층과 노년층 사이에는 큰 차이 없이 약간 긍정적이었고, 도시와 농촌 간에는 긍정적 정도가 엇갈리게 나타나고 있었다. 노인에 대한 인식은 세대 간과 연령에 관계없이 긍정적인 면은 거의 없는 반면에 부정적 면이 압도적으로 많았다. 본 연구는 또한 이러한 결과가 향후 수도권의 노인복지 정책과 서비스에 관련되는 함의도 제시하였다.

독립적이고 생산적인 노년기를 조망하는 성공적 노화라는 패러다임은 활기찬 인간관계 및 생산적 활동을 통한 적극적인 사회참여를 요구한다. 그러나 국내의 성공적 노화 연구에서는 배우자와 자녀관계를 넘어선 사회관계 및 사회활동에 관한 논의가 부족한 편이다. 본 연구는 성공적 노화와 관련하여 노인들이 다양한 사회활동들을 어떻게 인식하고 있는가를 설명하고자 한다. 즉 성공적 노화에 있어서 사회활동은 얼마나 중요하게 인식되는가, 여러 활동에 대한 인식의 공통성은 어떻게 유형화할 수 있는가, 이러한 인식은 연령층에 따라 다르게 나타나는가, 사회활동의 유형 인식에 영향을 미치는 개인의 특성과 환경적 조건은 무엇인가를 설명한다. 이를 위한 연구방법으로, 2008년 7월 10일~8월 23일에 구조화된 설문지를 이용하여 대면적 면접조사로 수집된 전국만 20세 이상 성인 1,000명 중에서 50세 이상 613명의 응답 자료를 분석하였다. 응답자들은 예비 노인, 전기 노인, 후기 노인으로 세분되어 사회활동과 관련된 인식을 비교하였다. 분석결과, 노인들은 기본적으로 성공적 노화를 위해서 사회활동에 참여해야 한다고 보지만, 개별 활동들의 중요성에 대한 인식은 차이를 보인다. 연령층별로 비교해 보면 특정한 활동을 강조하기보다 생애주기에 따라서 개인의 욕구와 동기에 따라 활동의 중요성이 바뀐다. 또한 여러 사회활동들에 대한 인식은 크게 생산적 활동과 관계적 활동의 범주로 분류되며, 연령층에 따라서 생산적 활동 또는 관계적 활동으로 인식되는 활동의 내용들이 다르게 연관되어 있다. 생산적 또는 관계적 활동의 선호는 성별, 거주지, 배우자유무, 자녀와 동거여부에 따라 다르며, 연령, 학력수준, 건강, 경제력은 유의하지 않은 반면 노후계획과 노동을 중시하는 태도는 일관되게 중요한 영향을 미치는 것으로 분석되었다. 이러한 특성은 사회활동 관련 정책 및 프로그램 체계에 반영되어야 할 것이며, 생산성을 중시하는 사회 활동의 강조는 정작 관계적 동기를 지향하는 노인층의 욕구와 괴리될 수 있다.
