Quercus aliena and Q. serrata are both occur as natural vegetation alongside natural freshwater bodies of the southern Korea Peninsula. Q. serrata dominates over Q. aliena as secondary forest vegetation in the present day. In order to explain these natural distributional traits of the oak species, we conducted some experiments with oak seedlings which treated with major important environmental resources, including light, moisture and nutrients, under controlled conditions. We then measured the ecological niche breadths and overlap from 15 eco-morphological characteristics. The ecological niche breadth of Q. aliena and Q. serrata were higher in terms of the nutrient factor applied, but was lower terms of light. The niche breadth of Q. serrata was wider than that of Q. aliena in light and moisture exposure. On the other hand, the niche breadth of Q. aliena was similar with that of Q. serrata in terms of the nutrient factor applied. These results imply that Q. serrata has a broader ecological distribution in over a wider variety of light and moisture environments than that of Q. alien. Ecological niche overlap between two oak species was the widest in terms of the light treatment factor applied, and narrowest in terms of moisture. This response pattern was also verified by cluster and principle component analysis. These results suggest competitive interactions between Q. serrata and Q. aliena seedlings may be higher for light resources than moisture or nutrient resources, and that Q. serrata is more shade tolerant than Q. aliena.

본 연구의 목적은 우리나라의 국민들의 올림피즘에 대한 의식을 유형화하고 각 유형에 대한 특성을 살펴보는데 있다. 연구대상자로는 올림피즘에 대한 의식에 차이가 있을 수 있기 때문에 비 체육관련 일반인 18명과 엘리트 운동선수 17명 총 35명을 P-sample로 선정하였다. 본 연구의 목적을 달성하기 위하여 주관성연구로 알려진 Q 방법론을 사용하였다. Q-표본은 올림피즘의 태도와 가치에 관한 문헌연구와 연구대상자의 인터뷰 및 개방형 설문지를 이용하여 34문항을 작성하였다. 자료처리는 P-표본(35명)에게 Q 분류를 하도록 한 후, QUANL PC Program을 이용하여 다음과 같은 결과를 도출하였다. 올림피즘에 관한 유형은 다섯 가지 유형으로 분석되었다. 첫째, 전통적 가치관, 둘째, 참가의 의미, 셋째, 경쟁과 승부, 넷째, 페어플레이, 다섯째, 윤리 의식으로 나타났다.

피음처리에 의한 네 참나무 수종(신갈나무, 졸참나무, 상수리나무, 굴참나무)의 광합성 반응 특성을 조사하기 위하여, 차광막으로 전천광을 35%, 55%. 75% 차광 처리한 조건과 전광조건에서 엽생장과 엽록소함량을 측정하고 광-반응 곡선과 A-Ci 곡선을 통하여 광합성계의 특성을 조사하였다. 그 결과, 굴참나무와 상수리나무는 엽생장, 엽록소함량, 순양자수율을 증가시키고 엽록소 a/b와 탄소고정효율을 감소시켜 빛의 흡수량과 광합성에 대한 이용효율을 높이는 적응 반응을 나타냈다. 신갈나무는 굴참나무와 상수리나무와 같은 경향의 적응반응을 보였지만 광합성 광화학계 활성의 저하로 낮은 광합성 능력을 나타냈다. 졸참나무는 가장 낮은 내음성 적응반응을 나타냈다.

In this paper, we establish an explicit formula for r-Dowling numbers in terms of r-Whitney Lah and r-Whitney numbers of the second kind. This is a generalization of the Qi formula for Bell numbers in terms of Lah and Stirling numbers of the second kind. Moreover, we define the q, r-Dowling numbers, q, r-Whitney Lah numbers and q, r-Whitney numbers of the first kind and obtain several fundamental properties of these numbers such as orthogonality and inverse relations, recurrence relations, and generating functions. Hence, we derive an analogous Qi formula for q, r-Dowling numbers expressed in terms of q, r-Whitney Lah numbers and q, r-Whitney numbers of the second kind.

Purpose: This study's purpose is to classify and analyze caregivers' recognition of the elderly suicidal intents. Methods: This study uses applied Q-methodology to measure human subjectivity in depth. Concretely, 35 statements are composed in depth interviews and literature investigation. Then, Q-cards and distributive chart of Q-sampling were given to 25 caregivers randomly-selected, who were asked to arrange them on a 7-score based. After coding Q-factor analysis is carried out with the PC-QUANL program. Results: Four types of indicators of the elderly suicidal intents were identified by the caregivers. These are Knowledge-based recognition, Behavioral measure based recognition, Negative comprehension and Sympathy. Conclusion: In this study, four types of recognition were yielded among the caregivers and the characteristics of each type were analyzed. These findings may be useful in assessing suicidal potential and nursing interventions.

In this paper, we study the generalizations of Euler numbers and polynomials by using the q-extension with p-adic integral on $\mathbb{Z}_p$. We call these: the generalized q-${\omega}$-Euler numbers $E^{({\alpha})}_{n,q,{{\omega}}(a)$ and polynomials $E^{({\alpha})}_{n,q,{\omega}}(x;a)$. We investigate some elementary properties and relations for $E^{({\alpha})}_{n,q,{{\omega}}(a)$ and $E^{({\alpha})}_{n,q,{\omega}}(x;a)$.

In this paper, weighted Bloch spaces $B_q (q > 0)$ are considered on the open unit ball in $C^n$. These spaces extend the notion of Bloch spaces to wider classes of holomorphic functions. It is proved that the functions in a weighted Bloch space admit certain integral representation. This representation formula is then used to determine the degree of growth of the functions in the space $B_q$. It is also proved that weighted Bloch space is a Banach space for each weight q > 0, and the little Bloch space $B_q,0$ associated with $B_q$ is a separable subspace of $B_q$ which is the closure of the polynomials for each $q \geq 1$.

Prader-Willi syndrome (PWS) is a rare genetic disorder which lead to severe neurodevelopmental, endocrine, and metabolic impairment. PWS is genetic disorder related to genomic errors which lead to inactivation of paternally-inherited genes on chromosome 15q11-q13. Epigenetic mechanisms are also involved in PWS, and epigenetic therapies are under investigation. Here we provide review about genetics of PWS, focused on genes involved in pathophysiology of PWS. We will also summarize epigenetics and genetic counseling of PWS.
