이 논문의 목적은 현재 40-50대의 중년층과 노부모 사이에 이루어지는 세대관계의 심층적 구조를 밝히고, 이 구조에 영향을 미치는 제반요인들을 설명하는데 있다. 그리고 세대관계의 유형에 따라 중년층 자신의 노후부양태도와 노후생활에 대한 대책행위가 어떻게 달라지는가를 분석하였다. 이 연구를 위해 구조화된 질문지를 활용하는 전국전인 면접조사가 이루어졌다. 이 논문은 중년층과 노부모의 세대관계를 세대간 근접성, 지원가능, 그리고 노부모 부양관 에 따라 다섯 가지 유형으로 분류하였다. 중년층의 지배적인 세대관계는 노부모와 별거하면서 지원기능을 유지하는 형태로 나타났다. 별거사항에서 이루어지는 지원관계에는 중년층의 사회 계층적 지위나 노부모와의 정서적 연대와 관련된 요인들이 중요하게 작용하는 것으로 밝혀졌다. 중년층 자신의 노후생활에 대한 부양관과 노후대책 행위는 세대관계의 유형에 따라 유의미한 차이가 존재한다. 근접성, 지원관계, 노부모 부양관 모두에서 전통적인 세대관계를 유지하는 중년층은 자신의 노후생활에 대해서도 가족의 부양을 강조하며, 독립적인 노후대책을 마련하는데 소극적이다. 반면, 노부모와 동거하고 지원기능을 유지하더라도 노부모부양관이 약한 증년층은, 자신의 노후 생활에 대하여 독립성을 강조하고, 스스로 노후대책을 마련하는데 적극적인 것으로 확인되었다.

Human communication researchers have suggested that good communication between husbands and wives is a key to a healthy marriage. Although interpersonal communication itself cannot "fix" all problems in one's marriage, the importance of good communication in a marital-relationship cannot be overstated. Regardless of its importance, the communication behavior between husbands and wives as a research topic has been paid little attention by human communication scholars in Korea. Because of the "intimacy" Korean couples who have been influenced with the long tradition of Confucius culture tend to overlook the communicative problems in a marital-relationship. Yet, it is "the belief" of the intimacy that creates much of the communicative problems in a marriage. This study is designed to explore the characteristics and transitional process of the communication behavior between Korean husbands and wives among generations. Married couples in their 20's, 30's, 40's, and 50's were surveyed with five levels of interpersonal communication process-open attitudes, problem-solving, expression, listening, and feedback. The study result reveals each generation's characteristics and transitional process of marital communication behavior from younger couples to older couples as their intimacy and "shared" lived-experience get accumulated.

한국 베이비붐세대는 은퇴 후 주거선택에서 은퇴 전과는 다르게 쾌적성과 편의성을 중시하여 선택할 가능성이 높을 것으로 예상된다. 또 은퇴 후에 주거면적을 일괄적으로 축소하는 것이 아니라 현재 보유 주택규모에 따라 다른 형태를 보일 것으로 추정된다. 그리고 은퇴 후 62.4%가 주거이동을 계획하고 있고 지역간 이동은 주거이동가구의 52.3%에 달하여 은퇴 후 활발한 주거이동이 예상되며, 지역내 이동과 지역간 이동에 영향을 미치는 영향변수도 다른 것으로 나타났다.

The primary purpose of this paper is to critically examine the theoretical and methodological issues in the study of generations. The issues include: 1) the concept of generation: 2) the basis of generational formation: 3) internal differentiation of generations: 4) the boundary problems of generations: 4) the boundary problems of generations: and 5) generational differences and generational conflict. From the investigation of these issues, two conclusions are drawn. Firstly, Mannheim's basic concepts and theoretical frameworks are very useful to understand and explain the social movements and sociocultural changes. Secondly, however, further elaboration and modification of the several concepts and frameworks are needed to deal with the problems of generations in general which are not directly connected to social movements. Several points are suggested to elaborate Mannheim's frameworks, which include the reconceptualization of generation, and introducing the concepts of “generation sects” and “manifest-latent generational conflicts”.

This study was carried out to investigate the life cycle and the damage of Tricholyga sorbillans Wiedmann to silkworms(Bombyx mori L.). The results are summarized as follows. 1. This insect has 5 or 6 generations per year in Suwon area. 2. The egg, larval, and pupal stage are about 2, 8 and 18 days respectively. 3. The weather conditions considerably affect the life cycle, that is, the 3 rd generation is the shortest of all, lasting for 21 days and l4 hours, and the 5th generation is the longest for about 40 days. 4. The larvae come out of silkworm bodies, burrowing into the ground 3.5cm to 10.5cm in depth before changing into the pupae. 5. This insect does not overwinter as pupa, but seems to do as larva, parasiting on the field insects. 6. The damage of Tricholyga sorbillans Wiedmann to silkworm was 27.9％, it is so high that the silk worms could not be reared outside without a reasonable control method. 7. When the full-grown silkworm is parasited by one egg of these insects, there is not only enough possibility of spinning. but also without any effects of their larvae on the cocoon quality. 8. The damage of Tricholyga sorbillans Wiedmann throughout the country covers 6.36％ in spring, 4.09％ in fall, and 5.25％ yearly mean.

While South Koreans overseas travelling rate has been increased every year, domestic travelling rate has been at a standstill for several years. The purpose of this study is to analyze domestic traveling styles of Koreans according to their generations in order to provide generation-specific traveling services. For this purpose, we categorized the survey respondents into four different generations, which are Millennium (age 19~34), X generation (35~54), Baby Boomer (55~64) and senior by following the criterions of the Korea National Tourism Organization. After then, we analyze factors related to travel preparation process, the actual traveling activities and satisfaction after the travel. In this study, 16,713 data collected by the Ministry of Culture, Sports and Tourism are used. The results of this study show that Korean people tends to acquire domestic traveling information from their own or acquaintances past experiences. Also, they do not prefer the organized trip for domestic travels, thus do not buy package products a lot. In addition, natural scenery, rich in cultural heritage, and convenient accommodation are the most important determinant factors affecting the overall travel satisfaction of level for all generations. The traveling characteristics for each generation are as follows. Millennium get traveling information from the internet a lot, and more specifically, they refer portal sites and social network services (SNS) in many cases. Also, they tend to travel in summer peak season to popular destinations and pursues active traveling experiences. Generation X has similar traveling patterns with Millennium, however they major transportation method is using their own car. Also, transportation convenience and satisfactory leisure activity are important factors affecting the overall satisfaction level to Generation X. On the other hand, Baby boomer generation has a greater emphasis on appreciation of nature, visiting famous restaurants, and relaxation, rather than actively participating experiencing programs. They travel evenly in summer and spring/fall season to many different areas instead of focusing on popular tourist spots. In addition, shopping and eating delicious food are the important factors affecting the overall satisfaction level for them. Lastly, Senior generation has similar characteristics with Baby boomer in many ways, however, they travel a lot on the same day using public transportations or car rental service. They prefer spring and autumn trips rather than summer peak season, and tend to buy packaged travel products a lot compared with other generations. If these different traveling characteristics of each generation are considered for organizing and customizing tourism services, it is expected that domestic tourism satisfaction level will be ultimately increased.
