Purpose of the research: In response to the increasing number of selling centers, this paper examines factors that influence the voluntary participation in selling centers. The goal of this study is to enable organizations to meet changing market conditions, which require interdisciplinary collaboration during sales projects. This paper also discusses potential problems which may occure during the implementation of these factors in practice. Research design and methodology: The research method consists of a qualitative cross-sectional study with N=12 interviewees. All interviewees are current or former selling center participants. During the interview sessions, semi-structured face-to-face interviews were used, which were evaluated using a qualitative content analysis. In addition, a frequency analysis was applied to evaluate the number of mentions per factor. Research results: In total, five factors were raised in order to improve the framework conditions of voluntary participation. These factors are performance incentives, transparency, availability of resources, goal orientation, as well as collegiality and affiliation. Major conclusions: The identified factors are also under discussion in the existing literature. Knowing about factors that generate voluntary participation in selling centers pays off particularly in improving the probability of completion of sales projects in which buying centers and selling centers are working together.

A combinatorial library of artificial transcription factors (ATFs) was introduced into the bacterial cells that expressed the Akt1-GFP fusion protein. By measuring the level of fluorescence generated by the transformed E. coli cells, we were able to obtain clones in which ATFs increased the solubility of the Akt1. Our results show that ATF library is a useful tool for increasing the solubility of selected recombinant proteins in E. coli.

In female elderly, mean height, weight, BMI, WHR, MAC, TSF, %body fat and systolic blood pressure were 150.3cm and 149.2cm, 55.9kg and 53.1kg, 24.4 and 23.4, 0.87 and 0.86, 25.4cm and 24.4cm, 20.2mm and 18.9mm, 37.2% & 35.4%, 142.2mmHg and 151.7 mmHg in the urban and rural respectively. As the age increasing, most of the anthropometric indices are decreased while systolic blood pressure are increased in both gender. The proportion of the subject with normal hearing were 73.1% in the urban, 61.4% in the rural and 61.8% in the male, 73.1% in the female. Hearing and tooth status became deteriorated as increasing the age and the more elderly felt themselves unhealthy as increasing the age. Aerobic(25.7%) and walking/jogging(18.4%) in the urban, walking/jogging (22.1%) and climbing(3.5％) in the rural were the preferred exercise in the elderly. Frequency of health promoting substance intake were very low and not significantly different between the urban & the rural, and the male and the female elderly. Neuralgia, diabetes, indigestion and cerebral stroke showed relatively higher morbidity in the elderly. Neuralgia was significantly higher in the female(23.3%) than in the male(13.1%). Diabetes was significantly higher in the female(22.4%) and the urban(21.9%) elderly than in the male(16.1%) and the rural(13.5%) elderly respectively. In conclusion, as the age increasing the height and weight of the elderly decreased significantly and BMI, WHR and body fat toned to decrease. Hearing and tooth status deteriorated significantly as the age increasing, especially in female elderly.

Medical Aid expenditure Increased rapidly at a higher rate than that of Medical Insurance during the period 1992-1999. To establish an effective cost containment strategy, knowledge of the cause and the nature of the increase of Medical Aid expenditure is required. The purpose of this study was to analyze increasing rates of Medical Aid expenditure by the components of medical expenses. Data were collected using the Medical Aid Statistical Yearbook during the period of 1992-1999. The major findings were as follows: 1. The annual mean increasing rate of Medical Aid expenditure between 1992 and 1999 was 22.8%, which exceeding that of Medical Insurance expenditure (17.5%) between 1992 and 1999. Since 1998, Medical Aid expenditure increased even more rapidly than in previous years, with the increase in number of Medical Aid beneficiaries. 2. Of Medical Aid expenditure, that of inpatient and outpatient annually increased 24.2% and 22.8% respectively and that of type 1 and type 2 increased annually 28.8% (outpatient) ∼29.9% (inpatient), 14.3% (outpatient) ∼ 15.5% (inpatient). Therefore, Medical Aid expenditure of inpatient and type 1 led the increase of Medical Aid expenditure. 3. Between 1992 and 1997, the frequencies of utilization per beneficiary and the charges per case positively contributed to the increase of Medical Aid expenditure while the number of beneficiaries contributed negatively, but since 1998, the number of beneficiaries increased and positively contributed to the increase of Medical Aid expenditure. 4. According to the analysis of the charges per case, the increase of the price index led to the increase of the charges per case but the days of medication and service intensity also contributed to the increase of the charges per case variably by year. Considering the above findings, factors associated with the Medical Aid system affected the increase of Medical Aid expenditure in addition to the general factors of the increase in medical expenditure. In conclusion, it appears that a more intensive cost containment strategy is required to control rapidly increasing Medical Aid expenditure. For this, more precise analysis and development of policy considering the effect of the number of beneficiaries and the increase of price index is needed.

This study was conducted for analyzing the contribution factors on ozone concentrations and its long term trends in each major city and province in Korea through several statistical methods such as simple linear regression, generalized linear model, KZ-filer, correlation matrix, Kringing method, and cluster analysis. The overall ozone levels in South Korea have been consistently increasing over the past 10 years. The ozone concentrations in Seoul, the biggest city in Korea, are the lowest in all areas with the highest increasing ratio for $95^{th}%$ ozone. It is thought that the active photochemical reaction could affect the higher ozone concentration increase. On the other hand, the ozone concentrations in Jeju are the highest in Korea with the highest increasing ratio for $5^{th}%$, $33^{th}%$, and $50^{th}%$ ozone. It is also thought that the weak $NO_x$ titration could be the reason of higher ozone concentrations in Jeju. In case of Jeju, transport related factors is the major factor affecting the ozone trend. Thus, it is assumed that the variation of ozone trend of Asian region affecting the ozone trend in Jeju, where domestic ozone photochemical reaction is less active than urban area. It is thought that the photochemical reaction plays the role of increasing of ozone concentrations in the urban area, even though the LRT affected on the increase of ozone concentrations in non-urban area.

The finite element method were used to determine the stress intensity factor of cracked plate. The stress method, displacement method and J Integral are most popular finte element method. ANSYS proposed another a kind of displacement method. In this paper, it was examined that the accuracy and utility of the ANSYS method could believable to determine the stress intensity factors of centered inclined crack. Generally, inclined crack has two portion of stress intensity factors, tensile mode F1 and shear mode F2. For the purpose of increasing the accuracy of stress intensity factors, examined the effect of the numbers of nodes and elements, crack tip element size and number of partition of the crack tip vicinity. It was found that the method proposed by ANSYS is useful and has high accuracy. Accuracy of calculated stress intensity factors was increased by increase of the number of nodes and elements, and at the small size of crack tip elements can get more highly accuracy.
