The distribution pattern of mineral nutrients, among various Parts of Korea ginseng (Panax ginseng C.A. Meyer) was investigated to understand ginseng nutrition by simple correlation analysis. Five·year old ginseng plants grown under four different nutritional environments were sampled and separated into leaf, petiole, stem, rhizome, cortex and epidermis of tap foot, central part of tap root, cortex and epidermis of lateral root, central part of lateral root, fine root in the middle of truly, for chemical analysis. Between mineral nutrients in root, N and P showed highly significant positive correlation each other and with Mg and Cu while all other elements (K, Ca, Mg, Fe, Mn, Zn, Cu, B) showed highly significant positive correlation each other. In shoot, number of mineral nutrient pairs haying significant relation was much less than in root. (Negative: P with Ca or B, K with N, Fe, Mn or Cu, Positive: N with Mg, Fe, Mn or Cu, K with Zn, Ca with Mg, Zn, or B, Fe Mn Cu each other, Mn with B.) The number of pairs having significant correlation in whole plant was approximately the same as the number in root but three of them showed significant negative correlation. The distribution pattern similarity of mineral contents among various parts was also discussed in relation to physiological significance in Korea ginseng plant.

본 논문에서는 참고문헌 [1], [2]에서 무손실 매질을 가정하고 보고하였던 ID-FDTD 기법을, 손실 매질로 확장시켜 정리하였다. 확장된 내용으로는 기법의 안정도 분석(stability analysis), 손실 매질에 대한 ID-FDTD 기법의 분산 관계(dispersion relation), 무손실 손실 매질 모두에 적용할 수 있는 보정치를 수식 등 크게 세 가지이다. 이러한 분석 결과 ID-FDTD 기법은 참고문헌 [3]의 standard 기법보다 큰 시간 증분에서도 안정성을 유지하면서도 적은 분산 오차(dispersion error)를 가지는 것을 확인할 수 있었다. 이는 두 가지 경우의 전자기파 산란 문제를 계산함으로써 검증하였다.

This study examined how the relationship between grandmother-adult child solidarity, caregiving satisfaction, and grandmother's child-rearing role varies according to the relation with the grandchild. Mediation effects and moderated mediation effects were analyzed to investigate the relationship between these variables. The participants were 295 grandmothers raising preschool-aged grandchildren in the Seoul and Gyeonggi areas. Data was analyzed using SPSS 23.0 and PROCESS macro, performing correlation analysis and hierarchical regression analysis. The statistical significance of the indirect effect was examined using a bootstrapping procedure. The results are as follows. First, grandmother-adult child solidarity directly affects the grandmother's child-rearing role. Second, grandmother-adult child solidarity indirectly affects the grandmother's child-rearing role through caregiving satisfaction. Third, the direct and indirect effects of grandmother-adult child solidarity on the grandmother's child-rearing role are moderated by the relation with the grandchild. The direct effect of grandmother-adult child solidarity on grandmother's child-rearing role was therefore shown to be significant on the maternal grandmother. Fourth, the indirect effect of grandmother-adult child solidarity on the grandmother's child-rearing role through caregiving satisfaction was shown to be significant on the paternal grandmother. Based on the results of this study, we discussed ways to strengthen the capacity of co-parenting between grandparents and adult children.

A scenario known as conflict in face recognition may arise as a result of some disparity-related issues (such as expression, distortion, occlusion and others) leading to a compromise of someone's identity or contradiction of the intended message. However, addressing this requires the determination and application of appropriate procedures among the various conflict theories both in terms of concepts as well as resolution strategies. Theories such as Marxist, Game theory (Prisoner's dilemma, Penny matching, Chicken problem), Lanchester theory and Information theory were analyzed in relation to facial images conflict and these were made possible by trying to provide answers to selected questions as far as resolving facial conflict is concerned. It has been observed that the scenarios presented in the Marxist theory agree with the form of resolution expected in the analysis of conflict and its related issues as they relate to face recognition. The study observed that the issue of conflict in facial images can better be analyzed using the concept introduced by the Marxist theory in relation to the Information theory. This is as a result of its resolution strategy which tends to seek a form of balance as result as opposed to the win or lose case scenarios applied in other concepts. This was also consolidated by making reference to the main mechanisms and result scenario applicable in Information theory.

The purpose of this study is to reveal that the concept of relation in the postwar CIAM's debate was the hot issue which leaded to the collapse of CIAM, and that Aldo van Eyck developed it into the concept of "in-between". The postwar CIAM's young members voiced a critique of the universalizing attitude toward dwelling that CIAM had pursued since 1928 and looked for a new approach that would take into account the relation around dwelling. So, this study reviews the concepts of relation which were proposed by the postwar CIAM's young members. As a result, it is revealed that Aldo van Eyck extended the concept of "in-between" not to have the polarities, such as inside/outside, close/open, part/whole, neutralize or cancel one another out, but to attune them in such a way that they reinforce each other by mutual contrast, while the other young CIAM's members limited it to transition or connection. And, this paper analyzes the Municipal Orphanage in Amsterdam which was presented in CIAM 10. Through the analysis, it is revealed that the building presents many polarities simultaneously such as those; indoor and out door realms, dynamics and immutability, part and whole, and so on. In conclusion, it is possible to recognize that the concept of "in-between" is the fundamental binary-compound relation that lies at the root of Aldo van Eyck's architectural thought and bears on an interaction on a reciprocal relation between the inhabitant and the built environment.

본 연구는 우리나라 초등학생들의 함수적 사고 능력의 실태를 알아보고자, 다섯 가지 유형의 함수적 관계로 구성된 검사지를 이용하여 2, 4, 6학년 학생 총 2087명의 반응을 분석하였다. 분석 결과, 함수적 관계에 대한 학생들의 이해는 지역규모나 성별에 따라 큰 차이가 나타나지 않았으며, 통계적으로도 유의미한 차이를 보이지는 않는 것으로 드러났다. 반면, 과제 유형이나 문제 상황별로는 학생들의 이해 정도에 다소 큰 차이가 나타났으며, 이러한 차이에 주의를 기울일 필요가 있음이 드러났다. 특히, x의 값이 임의의 수(${\Box}$)로 주어졌을 때 y값을 구하는 문항에서의 정답률은, x의 값이 큰수로 주어졌을때 y값을 구하는 문항에서의 정답률에 비하여 다소 높게 나타나는 경향이 발견되었다. 본 논문은 이러한 결과들을 토대로 초등학교에서의 함수적 사고 지도 방안에 대한 시사점을 제공하였다.

The recommended factored design wind load effects for overhead lattice transmission line towers by codes and standards are evaluated based on the applicable wind load factor, gust response factor and design wind speed. The current factors and design wind speed were developed considering linear elastic responses and selected notional target safety levels. However, information on the nonlinear inelastic responses of such towers under extreme dynamic wind loading, and on the structural capacity curves of the towers in relation to the design capacities, is lacking. The knowledge and assessment of the capacity curve, and its relation to the design strength, is important to evaluate the integrity and reliability of these towers. Such an assessment was performed in the present study, using a nonlinear static pushover (NSP) analysis and incremental dynamic analysis (IDA), both of which are commonly used in earthquake engineering. For the IDA, temporal and spatially varying wind speeds are simulated based on power spectral density and coherence functions. Numerical results show that the structural capacity curves of the tower determined from the NSP analysis depend on the load pattern, and that the curves determined from the nonlinear static pushover analysis are similar to those obtained from IDA.
