  • In this study, Non-$CO_2$ emission factors were estimated for the coal briquette boiler, which is the Korean heating system. As a result, the $CH_4$ and $N_2O$ emission factors of the coal briquette boiler were estimated to be $11.76gCH_4/TJ$ and $7.44kgN_2O/TJ$, respectively. The results showed that $CH_4$ emission factor was 12 times and $N_2O$ emission factor was 5 times higher than IPCC default value. Also the emission factors developed in this study were compared with a precedent study. The results indicated that were similar to open the air inlet of coal briquette stove because the combustion condition of this study was similar to that of coal briquette stove.

  • This study was conducted to find out the factors affecting the stages of behavioral change about GMO(n=202 university students). 52.0% of the respondents had no experience in GMO education, the stages of pre-contemplation and contemplation were 35.6% and 29.7%, respectively. Experience and awareness on GMO were the highest at 86.6% and 51.5%, respectively, and 55% of the respondents did not know about the implementation of the labeling system. Positive and negative perceptions on GMO score were 3.41 and 3.22, respectively. The need for the full labeling system of GM foods was 56.4%, the intention not to pay when the price rises due to the system was 70.8%. Regression analysis of factors affecting the stages of behavioral change showed health interest(t=2.10, p<0.05), educational experience(t=2.81, p<0.01), knowledge score(t=2.260, p<0.05), and negative perception(t=2.13, p<0.05). The results of this study suggest that in order to increase the stage of behavioral change in GMO, it is necessary to raise interest in health and knowledge and have the correct perception through GMO education

  • 지식기반사회에서 기업의 성장 동력은 물질적 경쟁우위 보다는 기업 내부, 즉 각 기업이 보유하고 있는 독특한 핵심역량에있다. 이는 창의적 조직 문화와 학습역량, 브랜드, 독창적인 마케팅 역량, 기술 등과 같은 무형의 요소를 말하는데, 따라서 지속적인 성장을 위해서는 이 요소들이 활성화되는 환경과 필요 요소를 우선적으로 파악하는 것이 중요하다. 이 연구는문헌연구를 통하여 조직 문화(organizational culture)와 조직 문화 변화(organizational cultural change)를 개념적으로 정의하고, 조직 문화 변화에 대한 조직원들의 태도와 저항 요인을 고찰하며, 조직 문화 변화 요소를 도출하였다. 도출된 성공 요소는 한국자산관리공사를 대상으로 실증적으로 적용하여 설명력을 높였다. 정보학의 관점에서 볼 때 이 연구는 다음 두 가지 시사점을 갖는다. 첫째, 지식의 대상이 암묵지인 인적 자산으로 확대되어 가고 있으며, 인적 자산은 매우 동태적인 속성을 갖고 있으면서, 조직 문화와 밀접한 관련성을 갖고 있다는 사실을 인식하는 것이다. 둘째, '도서관' 혹은 '지식정보센터' 는 자체의 조직 문화뿐만 아니라 그가 속한 모 기관의 조직 문화와 유리될 수 없다고 볼 때, 향후 조직 문화에 대한 관심과 연구가 매우 시급하다고 볼 수 있다.

  • 본 논문은 세계화 기후변화시대에 지역 경쟁력에 영향을 미치는 요인을 추정하고, 요인들의 상대적 중요성을 분석하는 데 목적을 두었다. 2001~2010년 동안 16개 광역시 도의 균형 패널 데이터를 구축하여 패널분석을 수행하였다. 1인당 지역민총소득을 종속변수로 하고 경쟁력 기반요인, 경제적 생산요인, 기후변화 적응요인을 설명변수로 하는 패널모델을 구축하였다. 본 연구에서는 모델 1(전형적인 지역 경쟁력 모델)과 기후변화 적응요인을 추가시킨 모델 2를 비교하였다. 실증분석 결과 종속변수에 가장 영향력이 높은 요인으로는 지식기반산업 비율과 인적자본으로 나타났으며, 에너지 비효율성이 증가하면 지역 경쟁력이 감소하는 것으로 추정되었다. 또한 모델 1에 비해 모델 2에서는 지역의 개방성과 기술혁신자본의 영향력이 상대적으로 더 증가하는 것으로 나타났다. 본 연구 결과를 통해 향후 세계화 기후변화시대에 지역 경쟁력을 강화시키는데 필요한 정책적 시사점을 제공하였다.

  • Nozzle is a part of sprayer and is consists of several elements; swirl plate, vortexchamber, cap and body. The travelling distance of sprayed particles is important in the wide reach nozzle. The factors to influence the travelling distance of the sprayed particles may be the helical angle of swirl plate, the distance of vortex hamber, the slope and the size of cap hole. The study was conducted to examine the effects of these factors on the travelling distance. The results of this study are summarized as follows; 1) There was higher positive correlation(+0.96) between the maximum travelling distance for which amount of sprayed particles was 5cc/cm min. and centro-position of the travelling distance. 2) There was a higher positive correlation(+0.85) between total discharge of sprayed particles and the centro-position of the travelling distance. 3) Main effects and interaction effects of helical angle, pressure, vortex chamber distance and cap slope were significantly affected the travelling distance of sprayed particles. 4) Main effects of helical angle, pressure and cap slope were especially highly significant to influence the travelling disance. 5) Helical angle, pressure, vortex chamber distance and cap slope influenced spraying forward velocity of dise hole, among which cap slope and pressure of nozzle was the most important factors. 6) Effect of change of helical angle on the travelling distance of sprayed particles, was generally a quadratic, the least value of the distance being showed about $45^{\circ}$ and the largest at about $15^{\circ}\;and\;55^{\circ}$, the decreasing rate of the change between $15^{\circ};and\;25^{\circ}$ was very small. 7) Effect of change of pressure on the travelling distance sprayed particles was generally a linear, the increasing rate of the charge was about 1.68, which was the most effective compared to the change of the other factors. 8) Effect of change of vortex chamber distance on the spraying distance was also generally a linear, the increasing rate being about 0.16, which was the least effective. 9) Effect of change of cap slope on the travelling distance was also generally a linear, the increasing rate was about 0.61 and its effect was about medium.

  • It is known that the development of medical science is influenced by various social environmental factors. Historically, Chinese Medicine developed the most during the Song Yuan dynasty, and the reason for this was known to be due to socio-political factors. According to recent studies, however, this period also had severe changes in climate and environment. Therefore, this study was conducted under the premise that this change in climate and environment influenced medical development. When looking at the coldness of the 11th~12th century and data indicating warming before and after this period, the Song Yuan dynasty went through drastic periods of climate change. Therefore, diseases related to heat such as bubonic plague, measles, and malaria were common. Furthermore, due to occasional wars during the Song Yuan dynasty, social unrest was aggravated and infectious diseases spread due to land development and environmental pollution. As the health of people were threatened due to these factors, the printing and distribution of medical text were encouraged, and during this process, the great 4 doctors of Jin-Yuan appeared. The reason why they studied cures for infectious diseases due to heat was related to climatic environment change. The development in medical science is closely related to socio-political factors, however the change in climatic environments are inevitably related to disease emergence as well. Therefore, it should always be taken into consideration as an important factor that promotes development in medical science.

  • This article examined relationships between selected variables, such as demographic background, care, treatment variables, environmental characteristics, and patient's daily behavior and mood change. Relationship were determined between independent variabltherapeutic-rapeutie approach, demographic data, environmental management approach-,and dependent variable-patient's daily behavioral and mood change. 35 patients selected within some criteria in a psychiatric ward, were obserbed during 5 weeks by use of Wyatt's Behavior & Mood Rating Scale ac-cording to the object of the study. At the same time, the frequence of the care and treatment were collected. Criteria for sample selection and independent variables as an influential factor to the patient behavioral change, based on a literature revienw and clinical experiences. Pearson's correlation and multiple regression analysis were used to determine the influfntial factors to the patient behavioral change. Systematic reading (r=.8324), Psychiatrist's individual interview (r=.5764), tranquilizer (r=.3441) and hospitalization processing date (r=.4143) were related with patient's behavioral change. That is these 4 variables can be said to influence to the patient's behavior and mood. A stepwise multiple regression analysis of the effect of the independent varibles of systematic reading, psychintrists individual interview, tranquilizer and hospitalization processing date on the dependent variable, patient's behavioral change was carried out. Systematic reading with on R²of. 69 revealed to be the main influential factor to the patient's behavior and mood change, as the next factor psychiatrist individual interview. A total inclusion of these factors revealed a 73% prediction for the patient's behavior and mood change. But the most influential factor was the interaction of the systematic reading and psychiatrist's individual interview.

  • Domestic distribution environment in Korea has rapidly and qualitatively been developed due to the open of distribution market. However, the function of commercial establishment goes beyond the place value that simple transaction of capacity takes place, and it is recognized as life groove space enhancing the satisfaction of costumers' purchasing pattern. For this reason, there has been the need to change the purchasing environment of commercial space. The change factors of commercial space contributed to the establishment of consumption identity formed by change of consumers' lifestyle and the purchasing pattern. It is necessary to see the change factors of the purchasing pattern as the conversion of distribution environment in terms of supplier and as the change of consumers' lifestyle in terms of consumers. In reality, however, the commercial facility ill-imitated the advanced model and qualitatively was developed. In this situation, the change of the purchasing pattern according to the conversion of facility is needed as an early stage. The purpose of this study is to analyze the overflow supply of commercial facility. Also It will discuss the plan characteristics of commercial space conversion of facility conforming to the change of the purchasing pattern that is predicted in the lifestyle on a conversion stage of facility.

  • FormFactors is one of the most critical design factors in early development of mobile phone, and proper selection of FormFactors is necessary for smoothness of product development and customer satisfaction. Especially, emergence of mobile convergence added so various functions besides its original call function that importance of selecting FormFactors has increased because multiform FormFactors are needed. However there is problem such as frequent change of decision making in existing process because established process picks out FormFactors sensibly and arbitrarily through idea pull and so forth. We proposed FormFactors selection process by Axiomatic Design, set approach method and block approach method for reasonable and systematical FormFactors selection. First of all, we set the purpose of mobile phone development, and it is examined by Axiomatic Design. FormFactors design matrix is deduced through this process, the numbers of axes and rails are proposed using set approach method, and then patterns of FormFactors are embodied by block approach method. Particularly process application was tried through case study of mobile phone development, and we ensured that new FormFactors can be presented to a designer by systematical verification if change of customer requirements occurs through our process.

  • This study examined the factors related to stages of dietary behavioral changes among 1449 child bearing aged women (mean age $\pm$ SD = 25.6 $\pm$ 5.3 years) residing in large cities. A self administered questionnaire was used to assess stages of dietary behavioral change, meal balance and regularity, food availability, nutrition knowledge, body mass index, nutrient intake, and psycho-social factors including self efficacy, perceived benefits and barriers, social modeling. Undesirable dietary behaviors (precontemplation and contemplation) were shown among 45.1-57.4% of the participants, among those, 33.4-43.0% were precontemplators. Participants' self efficacy scores associated with dietary changes were higher in specific situations (3.42) as compared to general situations (2.86). Similarly, they appeared to perceive more benefits (3.86) rather than barriers (2.76) by changing their inappropriate eating habits. Perception and accuracy scores of nutrition knowledge were relatively high, indicating 90.9 and 80.1, respectively. In terms of food availability at home, fresh fruits received the highest score, followed by milk and milk products, vegetables, meat, alcoholic beverages and soft drinks. In social modeling assessment, family members, as compared to friends, appeared to have better dietary habits. Stages of dietary behavioral change assessed in terms of meal regularity were associated with nutrient intake, showing higher energy and carbohydrate intakes but lower fat intake among those who belonged to the action and maintenance stage. They also presented higher self efficacy and perceived more benefits and less barriers regarding the change of undesirable eating habits. Fresh meat and vegetables were more available among those maintaining desirable dietary habits. Results of this study presented the significant relations of motivational and reinforcing social factors with stages of dietary behavioral changes and a need for the development of tailored nutrition education program considering these factors for child-bearing aged Korean women.
