This study examines the factors influencing Korean international adoptee's search for their birthparents. Considering that the search for birthparents is general needs for adoptees, Korean government should support their searching activities and, first of all, understand their characteristics. The research model was constructed based on the results of previous studies, and the data set of conducted by ministry of health and welfare was reanalyzed for this study. The subjects of the survey were Korean-born adoptees (who are more than 16 years old) in North America, Europe, and Australia. The research questionnaire was translated to English and French, and the survey was conducted on line. A total of 290 questionnaires were included in the analysis. Since survey was conducted on line, the missing rate of the data was relatively high. So, multiply imputed five data sets were used for analysis. Among the variables included in research model, the age group of adoptees, experience of identity crisis in their life, the first time when they became actively interested in Korean roots, the age at the time of adoption, and the attitudes of adoptive parents toward their search were significantly related to their search for birthparents. Adoptees in the age group of 30~34 had more actively participated in search compared to their reference group (which is the age group of more than 35 years old). The earlier they became actively interested in Korean roots, they tended to be more active in searching activities. Also, the experience of identity crisis in life and the age at the time of adoption were positively related to their search. Although most of adoptive parents have supported their search, the adoptees who reported that they didn't know their adoptive parents' attitude toward search, or their parents deceased had more actively participated in search for their birthparents. Some implications for adoption policy and practice were discussed based on the results of the study.

The purpose of this study is to understand the 'search' experiences of adoptive families. To understand their experiences in searching for birth families, the researchers made contacts with adoptive families who had tried the search before, got informed consents from them, and took in-depth interview with each family. The qualitative case study approach was taken to analyze the data collected. Data collected from five adoptive families were employed for within-case analysis and cross-case analysis. The themes emerged from cross-case analysis were 'the awareness of being adopted', 'curiosity explosion', 'the anxious waiting', 'the moment the truth was found', 'Indeed, I'm a real mom', and 'Then, there was a silence'. Based on the results of the study, the policy and practical guidelines to support the search of adoptive families were suggested. Also, the suggestions for the following studies were made to obtain more abundant information beyond the limitations of the study.

사람에게 족보가 있고 그 뿌리가 되는 조상이 있듯이 설비 자재 역시 족보가 있고 뿌리가 있다. 강철, 주철, 스테인레스 강 등은 원래 그 뿌리가 하나이지만 중간에 누구와 만나 결혼하느냐에 따라 특성이 전혀 다른 품격의 자손을 낳는다. 결국 최종 자재의 가격은 그 시조 및 부모의 특성, 탄생(?)의 난이도, 출생지 등에 따라 천차만별이 될 수밖에 없다. 따라서 자재 가격에 전략적으로 대응하려면 어느 한 면 만 보아서는 안되고 입체적으로 다각도로 여러 요인을 분석해 보아야 한다.

최근 해외에서 활동하는 한국계 작가들의 국내 소개가 활발하다. 일본과 영어권에서 활동하는 이들의 작품은 대체로 한국의 근.현대사를 배경으로 하고 있다. 작가의 개인적 체험과 시대적 상황묘사, 동양문화의 생경한 소재와 함께 서구인의 관심을 모으지만 정작 국내 독자의 반응은 무관심 한 편이다.

Root-knot nematodes represent a significant problem in cucumber, causing reduction in yield and quality. To develop screening methods for resistance of cucumber to root-knot nematode Meloidogyne incognita, development of root-knot nematode of four cucumber cultivars ('Dragonsamchuk', 'Asiastrike', 'Nebakja' and 'Hanelbakdadaki') according to several conditions such as inoculum concentration, plant growth stage and transplanting period was investigated by the number of galls and egg masses produced in each seedling 45 days after inoculation. There was no difference in galls and egg masses according to the tested condition except for inoculum concentration. Reproduction of the nematode on all the tested cultivars according to inoculum concentration increased in a dose-dependent manner. On the basis of the result, the optimum conditions for root-knot development on the cultivars is to transplant period of 1 week, inoculum concentration of 5,000 eggs/plant and plant growth stage of 3-week-old in a greenhouse ($25{\pm}5^{\circ}C$). In addition, under optimum conditions, resistance of 45 commercial cucumber cultivars was evaluated. One rootstock cultivar, Union was moderately resistant to the root-knot nematode. However, no significant difference was in the resistance of the others cultivar. According to the result, we suggest an efficient screening method for new resistant cucumber to the root-knot nematode, M. incognita.

Five of each lowland and upland rice varieties were planted in a seedling hox with three replications of randomized complete block design and it was desiccated up to complete water stress in certain leaf stage. The desiccated rice plants were supplied with water again to check survival ability of rice plant from wilting. All of the lowland varieties which showed lower yield in upland condition were superior to upland varieties in recovery ability from desiccation. Some of the morphological characteristics in relation to the recovery ability also were discussed.

Root-knot symptoms were found on a commercial tomato cultivar carrying Mi, a resistance gene to root-knot nematodes including Meloidogyne incognita, M. arenaria, and M. javanica in 2012 at Buyeo, Chungnam Province in Korea. The isolate was identified as M. incognita based on molecular analyses using two species-specific primer sets. Pathogenicity of the isolate on one susceptible and three resistant tomato cultivars to the root-knot nematodes was tested. The nematode isolate showed strong pathogenicity on all the tested cultivars at all tested incubation temperatures. In addition, resistance degree of 33 commercial tomato cultivars, 8 susceptible and 25 resistant cultivars to root-knot nematodes, was also tested. Plants were determined as resistant when they suppressed the nematode reproduction. All the cultivars demonstrated strong susceptibility to the nematode regardless of resistance of the tomato cultivars. To our knowledge, this is the first report on the occurrence of Mi infecting M. incognita isolate in Korea. On the other hand, to construct an efficient screening method for selecting resistant breeding source to the nematode isolate, root-knot development of M. incognita on four tomato cultivars according to several conditions such as inoculum concentration, plant growth stage, and incubation period after transplant was investigated. Reproduction of the nematode on all the tested cultivars according to inoculum concentration increased in a dose-dependent manner. Except for inoculum concentration, there was no significant difference in reproduction level of the cultivars according to the other tested conditions. On the basis of the results, we suggest an efficient screening method for new resistant tomato to the nematode isolate.

키케로는 ‘역사는 지나간 시간을 입증하는 목격자다. 즉 역사를 통해 현실을 밝아지고 추억은 생명력을 얻고 일상사의 지침을 제공받으며 태고의 소식들을 전해 받는다’고 했다. 또한 ‘역사는 현재와의 끝임 없는 대화’라고 한 역사가도 있고, ‘역사는 끊임없는 도전과 응전’의 과정이라고 말한 역사가도 있다. 그리고 크로체는 ‘모든 역사는 현대사일 뿐’이라고 했다. 어찌되었든 역사를 모르는 사람이나 민족은 오늘이라고 하는 현실이나 미래를 열어 가는데 있어 바른 방향이나 방법을 제대로 찾기 어렵다는 생각하는 것이 보편적이다. 특히 우리나라에서는 뿌리가 얼마나 중요한가. 자기의 역사를 제대로 아는 것, 그것이 오늘날을 잘 살아가기 위한 첫 번째 조건일 지도 모르겠다. 우리도서관계는 어떨까? 요즘과 같이 세대간의 단절이 점점 심화되는 상황에서 한 도서관 내에서도 직원들 간에 세대 차이를 느끼지 않을 수 없을 것이고, 그러한 세대 차이는 결국 도서관 운영의 합리성이나 직원들간 연대를 저해하는 요소가 될 수 있다. 따라서 세대간 대화의 촉진은 이제 조직의 구성과 운용에 중요한 과제가 되고 있다. 그래서 우리 ‘도서관문화’는 이번 월간으로 전환하는 시점에 지난 한 세대 전 우리 도서관계는 어떠했는지를 되짚어보는 지면을 마련했다. 30년 전후의 도서관 사정을 되짚어보는 것은 그 때의 사정과 정신을 오늘에 되살려, 오늘을 살아가는 우리에게 삶의 지침이 되기를 바라며, 나아가 새로운 미래를 열어 가는데 필요한 정신적 근거를 찾아보고자 한다.

In order to find a chemical agent which is able to modulate the activity of $H^+-ATPase$, microsomal preparation was obtained from the root tissue of tomato plant and the effect of $La^{3+}$ was measured. The activities of plasma and vacuolar membrane $H^+-ATPase$ were analyzed by the inhibited activities using their specific inhibitors, vanadate and $NO_3-$, respectively. $La^{3+}$ inhibited microsomal ATPases in a dose-dependent manner and the inhibitory effect of $La^{3+}$ was suppressed by both vanadate and $NO_3-$, implying that $La^{3+}$ inhibits both plasma and vacuolar membrane $H^+-ATPase$. The Ki. values of $La^{3+}$which inhibit 50% of the activities of plasma and vacuolar membrane $H^+-ATPase$ were 57 and $78\;{\mu}M$, respectively. The $H^+-ATPase$ of the leaky microsomes made by the treatment of Triton X-100 were also inhibited by $La^{3+}$, suggesting that $La^{3+}$ directly inhibits both enzymes. Meanwhile, the inhibitory effect of $La^{3+}$ was decreased by increasing the concentration of ATP, The effect of ATP was also concentration-dependent and 7 mM ATP completely removed the inhibitory effect of $La^{3+}$. These results imply that $La^{3+}$ inhibits both plasma and vacuolar membrane $H^+-ATPases$ by decreasing the binding affinity of ATP and $La^{3+}$ can be used to control the activity or root $H^+-ATPases$.
