This article deals with how and why rational choice theory is different from the secularization thesis concerning the stability of religious demand, which is one of the most important differences between the two sides, as representative of the new paradigm and old paradigm respectively. Basically, the latter sticks to the declining influence of or interest in religion and hence assume that the whole religious demand in a society is not stable. As religious pluralism deepens the process of secularization, religious institutions are considered to experience a reduction of their authorization, legitimacy, and social functions. The old paradigm argues that the decline of religious demand is unavoidable in any modernized societies because religion and modernization is basically incompatible. In contrast, rational choice theorists suppose that the whole stock of religious demand is stable in any societies, even if religious preference differs from person to person. A variety of religious preference is discouraged by religious monopoly or oligopoly, but encouraged by religious competition. Religious vitality in society is made and kept by free competition among various religious firms which strive to survive a religious market. The new paradigm emphasizes the quantity and quality of religious service that religious firms supply in order to attract potential or current religious demanders, ranging from atheists to fundamentalists. Supply-side factors such as religious organization, preaching, marketing strategy, and fellowship program are the primary determinant of religious change. Without the assumption of the stability of religious demand, therefore, the new paradigm cannot explain the importance of the supply-side factors. Differences between secularization theory and rational choice theory stem from how each theory sees the stability of religious demand. They are two major paradigms of the sociology of religion interested in understanding how and why religions change in contemporary societies. Nonetheless, the latter seems more helpful with our making religious enactment and policy about a socio-structural orientation where our religious economy should move toward.
비용에 근거한 공항사용료 결정에 관한 연구 -항공기 착륙료 중심-
유광의 ( Yu Gwang Ui ) 한국항공우주정책·법학회 2003 한국항공우주정책·법학회지 Vol.17 No.-
The objectives of this study are to develop more practical and efficient model concerned with airport charge, especially with aircraft landing charge. This study utilizes average pricing and marginal pricing theory as well as cost accounting theory. The average pricing method is useful to make total costs recovery possible in uncongested situation where the marginal costs are too low to recover the total costs of service. The utilization of cost accounting theory with marginal cost pricing theory would improve the practical applicability of the model. In addition, it is necessary to apply cost accounting information in order to estimate more exact cost for the service of landing and take-off of each aircraft type.
살충제 영향에 따른 담수산 지각류 Moina irrasa 의 생장과 생식에 관한 연구
유광일,남현우,김세화 ( Kwang Il Yoo,Hyun Woo Nam,Se Wha Kim ) 한국환경생물학회 1998 환경생물 : 환경생물학회지 Vol.16 No.1
To investigate the pesticide effect of a frsh-water cladoceran Moina irrasa, experiments were conducted in three mesocosms with three different pestide concentrations (control, 0.001 ㎖ ℓ^-1, 0.005 ㎖ ℓ^-1) in waters of a rice field in the vicinity of Inchon City (126°43`E, 37°6`N). Water temperature ranged 15.7 to 28.4℃, and pH varied from 7.22 to 8.32 in the control, respectively. Population density of M. irrassa at control ranged from 542 to 2,584 indiv. ℓ^-1. At 0.001㎖ ℓ^-1 and 0.003㎖ ℓ^-1 of pesticide, population density of M. irrassa ranged from 214 to 1,123 and 130 to 1,154indiv. ℓ^-1, respectively. After 4 hours from the experiment, the population density of M. irrasa declined intensively at pesticide treatments, and no individuals were found after 16 hours of the experiment at 0.001 ㎖ ℓ^-1 and after 12 hours at 0.003 ㎖ ℓ^-1. Mean fecundity represented by mean clutch size in terms of the number of embryos per batch at each individual varied between 9.8-17.84 at control, and 12.67-16.48, 15.87-16.64 at 0.001 ㎖ ℓ^-1 and 0.003 ㎖ ℓ^-1, respectively. There were found the individuals only with over 12 embryos at 0.001 ㎖ ℓ^-1 and 0.003 ㎖ ℓ^-1.
남극반도 주변 Ice Edge Zone 에서의 하계 모악류의 분포
유광일,김원록,김동엽 ( Kwang Il Yoo,Won Rok Kim,Dong Yup Kim ) 한국환경생물학회 1998 환경생물 : 환경생물학회지 Vol.16 No.1
To study the distribution of chaetognaths in Ice Edge Zone near the Antarctic Peninsula during austral summer, samples were collected at 35 stations between Bransfield Strait and northwestern Weddell Sea from December, 1993 to January, 1994. Chaetognaths were consisted of three species, Enkrohnia hamata, Sagitta gazellae and Sagitta marri. The abundance of chaetognaths was 0∼1,359ind./1000㎥ and high values were observed in the northwestern Weddell Sea. Eukrohnia hamata and Sagitta gazellae were distributed widely in Bransfield Strait and northwestern Weddell Sea. The abundance of Eukrohnia hamata was high in northwestern Weddell Sea but it was dramatically dropped in the Bransfield Strait. The abundance of Sagitta gazellae was high in Gerlache Strait and northwestern Weddell Sea and S. marri was very low and showed restricted distribution. The vertical distribution of chaetognaths were mainly confined to 150m and highest density were found in bottom water.

The present study has been carried out to clarify the taxonomy and distribution of the genus Lucifer in Korean waters. The samples were collected during the period from March, 1987 to February, 1989. five species from seven areas of Lucifer were identified : L. chacei, L. hanseni, L. intermedius, L. penicillifer, L. typus, All species were described and illusterated for the first time in Korean waters. From the distributional viewpoint, L. intermedius occurred most abundantly in all areas, but L. typus occurred only in the cheju area. Regionally, all the five species of Lucifer were found in the Cheju area. In Youngkwang area, only one species, L. intermedius occurred.

Seasonal variation of Chaetognaths in the coastal waters off Kori, was studied. Samples were collected monthly during the period from March 1988 to February 1989 at 30 stations. Ten species belonging to three genera were identified: Sagitta crassa, S. nagae, S. enflata, S. minima, S. regularis, S. robusta, S. neglecta, S. ferox, Pterosagitta draco and Krohnitta pacifica. Mean abundance of chaetognaths changed monthly from 0 to 165 individuals m^-3. The predominant species varied with month; Sagitta crassa occurred abundantly from April to July, S. enflata from August to November and S. nagae occurred throughout the year except for March.

Studies on the spatial distribution of chaetognaths have been carried out on the based of materials collected in the Yellow Sea in Auguest, 1982. As a result, 5 species belonging to two genera occurred; Sagitta crassa, S. enflata, S. nagae, S. regularis and Krohnitta pacifica. A key to the chaetognaths are given. Sagitta nagae was revealed to be a indicator species of the purturbed area formed by the mixing of the warm water current and neritic waters in summer season in the Yellow Sea.
