식민지 시기 조선의 인구동태는 한반도 안과 밖에서 역동적으로 진행되었다. 한편으로 자연성장률이 크게 성장하였고, 국내외 이동도 활발하게 이루어졌다. 이 연구는 식민지 시기 동안 정확히 얼마만큼의 조선인의 인구성장이 이루어졌고, 그 동태의 특성은 무엇인가를 밝히고 있다. 식민지 조선 인구 동태의 중요한 특성은 무엇보다 조선 안에서의 완만하거나 정체된 인구성장과 대비하여 만주와 일본에서의 조선인의 급속한 증가로 요약할 수 있다. 식민지 시기 조선내 인구의 자연성장율은 1910년-1915년 사이 10.57%o에서, 1935-1940년에는 20.4%o, 1940-1944년에는 24.4%o로 증가하였다. 그런데 식민지 시기 자연성장율이 실질적으로 크게 증가했음에도 불구하고 조선 내 인구성장이 1930년대 중반부터 떨어지고 이후 정체되었다. 이는 많은 인구가 만주와 일본에 이출한 때문이다. 식민지 기간 동안 조선의 인구는 1,260만 여명이 증가하였는데 그 중 약 69%인 870 만여 명이 한반도 안에 있고 31%가 만주와 일본으로 유출되었다. 집단적인 디아스포라의 경험은 해방 이후의 정치 역학과 사회 구성에 중요한 영향을 미쳤다. 또한 귀환하지 않은 해외 조선인들의 국적과 민족 정체성을 둘러싼 긴장은 지금도 해결되지 않고 있다.

The purpose of this study is to investigate the direct and indirect modes of influences environmental dynamism exerts on opportunism, one of important relationship factors. This study particularly delves into the indirect modes of influence in terms of control strategy (control mechanism) and control structure (bureaucratic structuring). To this end, a survey research has been conducted of 200 suppliers in business relationships with Korean hypermarket retailers. An analysis of the collected data indicates that while environmental dynamism has a positive influence on the control mechanisms such as monitoring and incentives, it does not have a negative influence on the control structure such as participation. And then it has a positive influence on the opportunism of suppliers. In addition, participation has a negative influence on the opportunism, but monitoring and incentives do not have a negative influence on it. This study discusses how both retailers and their suppliers should respond to the domestic retail business environment with highly dynamic characteristics, in order to achieve a long-term win-win partnership with one another. It also presents ideas to retailers with regard to what kinds of management strategies and management efforts required to effectively control the opportunism of suppliers.

The purpose of this study was to examine the allometric analysis of roxithromycin using pharmacokinetic data. The pharmacokinetic parameters used were $half-life(t_{1/2})$, mean residence time (MRT), clearance (Cl) and volume of distribution at steady state $(V_{ss})$. Relationships between body weight and the pharmacokinetic parameter were based on the empirical formula $Y=aW^b$, where 'Y' is $t_{1/2}$, MRT, Cl, or $V_{ss}$, W the body weight and 'a' is an allometric coefficient (intercept) that is constant for a given drug. The exponential term, 'b', is a proportionality constant that describes the relationship between the pharmacokinetic parameter of interest and body weight. As results of the allometric analyses, the logarithms of $t_{1/2}$, MRT, Cl, and $V_{ss}$ were linearly related to the logarithms of body weight. Results of the current analyses could provide information on appropriate doses of roxithromycin for all species.

In today's world, the ability to adapt to the rapidly changing environment is fundamental to the survival and success of any organizations. This is particularly true for the Korean retailing industry which is in the throe of sweeping developments. Against the backdrop of an increasing importance of the environmental factors, it is imperative to look into what efforts are required of corporate enterprises in order to achieve successful long-term partnerships between and among the parties involved in the retail value chain. In spite of the critical importance of the need to understand the environmental factors and their influences on the retail value chain, a serious theoretical and empirical study into this subject has never been conducted. Moreover, previous research has overlooked the various mechanisms influencing the value chain in terms of ,control strategy' and 'control structure'. The purpose of this study is to investigate the direct and indirect modes of influences environmental dynamism exerts on opportunism, one of important relationship factors. This study particularly delves into the indirect modes of influence in terms of control strategy (control mechanism) and control structure (bureaucratic structuring). To this end, a survey research has been conducted of 200 suppliers in business relationships with Korean hypermarket retailers. The survey results show that environmental dynamism has a positive correlation with the opportunism of suppliers. In addition, the control mechanisms such as monitoring and incentives employed by retailers, in turn, have an indirect influence on the opportunism of suppliers. In other words, the monitoring of retailers has a positive correlation with the opportunism of suppliers, while the use of bureaucratic structuring has a negative correlation with opportunism. This study discusses how both retailers and their suppliers should respond to the domestic retail business environment with highly dynamic characteristics, in order to achieve a long-term win-win partnership with one another. It also presents ideas to retailers with regard to what kinds of management strategies and management efforts required to effectively control the opportunism of suppliers.

This experiment was carried out to elucidate the behavior of nutrition absorption and the acid tolerance, on varying soil pH levels, of Pinus thunbergii, Pinus densiflora, Pinus rigida, PInus koraiensis, Larix leptolepis and Abies holophylla which are 6 month old seedlings through examinations of the absorption behavior, the acid and alkali tolerance of N,P,K, Ca and Fe in the sand culture media with artificially controlled pH. 1. The increase rate of dry matter conditioned by the behavior of nutrition absorption in a strong acidic condition (pH3) was found in the following decreasing order of Pinus rigida, Pinus thunbergii. This order, therefore, can also be said to apply to the case of acid tolerance. 2. The increase rate of dry matter in a strong alkaline condition (pH9) was found in the following decreasing order of Pinus thunbergii, Pinus rigida, Pinus densiflora, Pinus koraiensis, Abies hoplohylla, Larix leptolepis. This order, therefore can be said to apply to the case of alkali tolerance. 3. Considering the absorption behavior of K and Ca, it is possible to decide the tolerance of acid from the absorption behavior and it can be said that if the absorption quantity is K>Ca the acid tolerance is strong and vice versa. 4. Considering the ratio of K:Fe and Ca:Fe in this experiment, a strong acid tolerance shows a higher ratio of K/Fe and vice versa. And also a strong acid tolerance shows a lower ratio of Ca/Fe and vice versa. It is therefore possible to decide the acid tolerance from the absorption behavior of K, Ca and Fe. 5. Of the tree species subjected to this experiment, Pinus thunbergii was the strongest in both acid and alkali tolerance. 6. In spite of that in all species the dry weight in the root is smailer than that in the top, the quantity of Fe contained in the root was larger than that in the top.

현재 세계적 불황은 영원히 지속되지 않을 것이지만, 일본의 인쇄산업은 이후에도 저성장, 혹은 감소시대가 계속될 것으로 예상된다. 이런 예측의 배경에는 일본이 인구 감소 및 인구동태의 변화라는 사회구조의 변화, 또한 관련 기술(전자미디어, 네트워크 등)의 진보와 변화에 따른 대체기능(인쇄물이 담당하던 역할일 변화하는 것을 의미함)등이 있다. 많은 인쇄인들은 이런 저성장시대를 어떻게 살아가야만 할 것인가를 염려하고 있으나 몇가지 대안이 될 수 있는 방안을 제시하고자 한다.

Effects of nitrogen and phosphorus fertilization on nutrient dynamics and litterfall production were determined in adjacent 41-year-old plantations of Pinus rigida Miller and Larix kaempferi Gordon on a similar soil in Yangpyeong, Gyeongggi Province. Litterfall production were significantly different among sampling dates and between the tree species, whereas it was not significantly different among the treatments. Total annual litterfall production was 6,377 kg/ha for P. rigida and 4,778 kg/ha for L. kaempferi, respectively. Litterfall nutrient concentrations of L. kaempferi were higher than those of P. rigida. For both tree species, litterfall nutrient concentrations were highest in summer when the least litterfall production occurred, and lowest in late-autumn when the greatest litterfall production occurred, except for Ca in the L. kaempferi stand. The amount of total organic matter in the forest floor of P. rigida and L. kaempferi plantations were 24,296 kg/ha and 10,763 kg/ha, respectively. Forest floor N and P contents were 126, 10 kg/ha for P. rigida and 102, 8 kg/ha for L. kaempferi, respectively.

This paper presents a dynamic analysis of the interaction between incumbent firms and successful new entrepreneurs, that can provide R&D incentives when innovations are cumulative/sequential. It is argued that the insights of the basic model extend to varying market structures and regulatory environments.
