본 연구는 아동기의 주거빈곤기간이 청소년의 주관적 행복감에 어떻게 영향을 미치는지 확인하고자 한다. 특히 기존연구를 통해 청소년의 주관적 행복감의 주요 영향요인으로 알려져 있는 가족관계나 또래관계, 그리고 학교적응이 주거빈곤기간과 청소년의 행복감 사이를 매개하는지 살펴보고자 한다. 이를 통해 아동 청소년이 행복한 사회가 되기 위한 사회적 노력의 일환으로써 주거복지정책은 어떠한 방향으로 수립되어야 하는지 기초자료를 제공하고자 한다. 이를 위하여 한국복지패널 제1,4,7차년도 자료를 이용하였으며, 7차년도 아동부가조사에 최종 조사 완료한 512명의 고등학교 연령대 청소년을 대상으로 하였다. 분석을 위하여 구조방정식 모형을 사용하였으며, 주거빈곤기간은 최저주거기준미달기간과 주거비과부담기간을 통해 측정하였다. 매개변수로 사용한 가족관계는 부모의 교육참여, 부모의 지도 감독, 가족갈등을 통해 측정하였으며, 학교적응은 학교환경과 학교유대감, 그리고 또래관계는 친구애착과 친한 친구의 또래애착으로 측정하였다. 종속 변수는 청소년의 주관적 행복감 척도를 통해 측정하였으며, 청소년의 성별과 가구소득의 영향을 통제하였다. 분석 결과, 최저주거기준미달 기간이 길수록 가족관계와 청소년의 주관적 행복감에 부정적 영향을 미치는 것으로 나타났다. 또한 최저주거기준미달로 인한 부정적 가족관계는 청소년의 학교 적응과 또래관계에도 영향을 미쳐 청소년의 주관적 행복감에 부정적 영향을 주고 있었다. 주거비과부담기간의 경우 주거비과부담기간이 길어질수록 아동의 주관적 행복감이 직접적으로 부정적 영향을 받았다. 요컨대 최저주거기준미달기간의 경우 가족관계를 통한 간접적 효과가 있는 반면에 주거비과부담기간의 경우 아동의 주관적 행복감에 직접적으로 부정적 효과가 확인되었다. 주거빈곤기간이 길수록 아동권리보장의 최종상태라 할 수 있는 주관적 행복감에 부정적이라는 본 연구결과는 아동 청소년 가구의 주거빈곤문제를 감소시키기 위한 사회적 노력을 요구하고 있다.

Currently, Social Media, it has widely a renown keyword and its related social trends and businesses have been fastly applied into various contexts. Social media has become an important research area for scholars interested in online technologies and cyber space and their social impacts. Social media is not only including web-based services but also mobile-based application services that allow people to share various style information and knowledge through online connection. Social media users have tendency to common identity- and bond-attachment through interactions such as 'thumbs up', 'reply note', 'forwarding', which may have driven from various factors and may result in delivering information, sharing knowledge, and specific experiences et al. Even further, almost of all social media sites provide and connect unknown strangers depending on shared interests, political views, or enjoyable activities, and other stuffs incorporating the creation of contents, which provides benefits to users. As fast developing digital devices including smartphone, tablet PC, internet based blogging, and photo and video clips, scholars desperately have began to study regarding diverse issues connecting human beings' motivations and the behavioral results which may be articulated by the format of antecedents as well as consequences related to contents that people create via social media. Social media such as Facebook, Twitter, or Cyworld users are more and more getting close each other and build up their relationships by a different style. In this sense, people use social media as tools for maintain pre-existing network, creating new people socially, and at the same time, explicitly find some business opportunities using personal and unlimited public networks. In terms of theory in explaining this phenomenon, social capital is a concept that describes the benefits one receives from one's relationship with others. Thereby, social media use is closely related to the form and connected of people, which is a bridge that can be able to achieve informational benefits of a heterogeneous network of people and common identity- and bonding-attachment which emphasizes emotional benefits from community members or friend group. Social capital would be resources accumulated through the relationships among people, which can be considered as an investment in social relations with expected returns and may achieve benefits from the greater access to and use of resources embedded in social networks. Social media using for their social capital has vastly been adopted in a cyber world, however, there has been little explaining the phenomenon theoretically how people may take advantages or opportunities through interaction among people, why people may interactively give willingness to help or their answers. The individual consciously express themselves in an online space, so called, common identity- or bonding-attachments. Common-identity attachment is the focus of the weak ties, which are loose connections between individuals who may provide useful information or new perspectives for one another but typically not emotional support, whereas common-bonding attachment is explained that between individuals in tightly-knit, emotionally close relationship such as family and close friends. The common identify- and bonding-attachment are mainly studying on-offline setting, which individual convey an impression to others that are expressed to own interest to others. Thus, individuals expect to meet other people and are trying to behave self-presentation engaging in opposite partners accordingly. As developing social media, individuals are motivated to disclose self-disclosures of open and honest using diverse cues such as verbal and nonverbal and pictorial and video files to their friends as well as passing strangers. Social media context, common identity- and bond-attachment for self-presentation seems different compared with face-to-face context. In the realm of social media, social users look for self-impression by posting text messages, pictures, video files. Under the digital environments, people interact to work, shop, learn, entertain, and be played. Social media provides increasingly the kinds of intention and behavior in online. Typically, identity and bond social capital through self-presentation is the intentional and tangible component of identity. At social media, people try to engage in others via a desired impression, which can maintain through performing coherent and complementary communications including displaying signs, symbols, brands made of digital stuffs(information, interest, pictures, etc,). In marketing area, consumers traditionally show common-identity as they select clothes, hairstyles, automobiles, logos, and so on, to impress others in any given context in a shopping mall or opera. To examine these social capital and attachment, we combined a social capital theory with an attachment theory into our research model. Our research model focuses on the common identity- and bond-attachment how they are formulated through social capitals: cognitive capital, structural capital, relational capital, and individual characteristics. Thus, we examined that individual online kindness, self-rated expertise, and social relation influence to build common identity- and bond-attachment, and the attachment effects make an impact on both the willingness to help, however, common bond seems not to show directly impact on information sharing. As a result, we discover that the social capital and attachment theories are mainly applicable to the context of social media and usage in the individual networks. We collected sample data of 256 who are using social media such as Facebook, Twitter, and Cyworld and analyzed the suggested hypotheses through the Structural Equation Model by AMOS. This study analyzes the direct and indirect relationship between the social network service usage and outcomes. Antecedents of kindness, confidence of knowledge, social relations are significantly affected to the mediators common identity-and bond attachments, however, interestingly, network externality does not impact, which we assumed that a size of network was a negative because group members would not significantly contribute if the members do not intend to actively interact with each other. The mediating variables had a positive effect on toward willingness to help. Further, common identity attachment has stronger significant on shared information.

최근 페이스북, 트위터 등 다양한 소셜 네트워크 서비스(SNS)가 등장하였으며, 많은 사용자들이 SNS를 이용하고 있다. 이러한 사용자의 증가로 인해 많은 조직들은 SNS에 관심을 가지게 되었다. 조직에서 SNS의 사용은 다양한 이점을 지니고 있다. SNS를 통해 조직들은 사용자들의 행위에 신속하고 지속적으로 반응할 수 있고, 다양한 특성을 지닌 사용자에게 쉽게 접근할 수 있으며, 타 매체에 비하여 사용자 특성이 반영된 차별화된 전략을 세울 수 있다. 또한 기업들은 SNS를 통해 상대적으로 저렴한 비용으로 활용이 가능하며, 사용자들과 양방향 소통이 가능하여 친근성과 신뢰성이 있는 관계 구축이 용이하다. 그러나 네트워크의 특성에 따라 SNS의 정보전달의 효과가 다르게 나타남에도 불구하고 조직들은 네트워크의 특성을 고려하지 않고 획일화된 방법으로 SNS를 활용하여 사용자들과 커뮤니케이션하고 있다. 따라서 본 연구에서는 네트워크에 따른 SNS의 정보전달의 효과 차이를 분석하였다. 즉 오프라인에서의 커뮤니케이션 기반으로 형성된 네트워크와 무작위로 형성된 네트워크를 생성하여, 각각의 네트워크들의 특징 차이를 분석하기 위하여 소셜 네트워크 분석을 하였다. 또한, 각각의 네트워크에서 SNS를 이용한 정보 전달 효과의 차이가 있는지 실증적으로 검증하였다. 실증 분석후 네트워크의 특성에 따라 네트워크 내 사용자들은 SNS를 받아들이는 반응이 달랐다. 따라서 조직이 효과적인 마케팅 수단으로 소셜 네트워크를 활용하기 위해서는 그 목적에 따라 네트워크의 특성을 고려하여 적절한 네트워크 형태를 구성해야 함을 도출하였다.

It seems common for students living at a small county and islands to experience psychological conflicts and be unaccustomed in the peer society because they are not familiar with peer interaction and social skills. This is a case study of L (hereinafter called L) who was grown up in the sheltered school at a small county. L was psychologically disturbed because he couldn't get along well in the transferred school. It is the reason why he had lived in the sheltered school at a small county, so he had not enough exposure to interact with peer and social skills. Sometimes he was obstinate irrationally and when he had trouble with friends, he threw something out or went out of school and tricked juniors dangerously. The fact of disperse with families, parent's indifference, and hate of older brother made L to have ill feeling against family. He had low motivation and low self confident in learning because of short attention time and accumulated poor learning progress. In this study, he was evaluated at various area, such as, intelligent, affective, personal and inter-personal, before counselling. To evaluated the effect of the counselling, K-WISC-III, KPRC, sentence filling test, social adaptation ability test, etc, were administered right after the counselling was over and 8 weeks later. For specific information gathering and analysing, observation diary and deepen counselling were accomplished by homeroom teacher, his mother, and his peers. To correct his problematic behaviors, 13 counseling sessions were accomplished for 6 months and those counselling sessions were recorded and analysed definitely. Followings are the result of this case study. First, he was recovered from the anxiety of inter-personal interaction and he started to interact with peers. The result of sac scale score of KPRC profile was lower than before as much as average student after counseling and 8 weeks later. This reveals that the distress against interpersonal relation have settled. Especially, through the result of sentence filing test, he seemed to feel attachment to peers and be positive, active in the relation of peer. For instance, he was active in the open class lesson and interacted well with peers. It could be said that he overcame the psychological distress comparing with previous time. Second, he could apologize to his peer and juniors for his fault. His attitude were well shown in the letter from an old friend at the sheltered school, average KPRC profiling score comparing with previous counseling time, and remarkable decrease of attack scale score of teacher and peer. Third, his view toward family turn out positive. He recognized his situation that he lived apart from family and even worried about his parent's financial difficulty. Through solving the confliction with his older brother, he could acquire the feeling of family reunion. Fourth, his learning motivation and self-confidence were increased. He confirmed his future positively and he might be judged more attentive because his intelligence index was higher than before as much as average student. With the main goal of this study, verification for effectiveness of counseling. understanding and helping problematic students such as L who lives at a small county and island through investigation of their real situation and problems with the method of counseling and socio-cultural analysis is worthwhile. Identification of ideal relationship with peer is related with positive self-conception, harmonic social adaptation and development of child. It is time to investigate easy adaptive in classroom and well-organised program to acquire general social skills for sheltered school students at a small county and islands.

본 연구는 농촌 노인의 여가활동 실태와 생활만족도에 미치는 요인을 밝히고, 이들이 참여하는 여가활동은 몇 가지로 분류되며, 여가 활동 참여도와 생활만족도는 어떠한 관계가 있는지 밝히기 위해 고흥군 도화면과 포두면에 거주하는 65세 이상 노인인구 220명을 대상으로 1998년 2월 16일부터 3월 3일까지 직접 면접을 통한 설문조사를 실시하여 분석한 결과는 다음과 같다. 첫째, 여가활동 내용에 있어서 가장 많이 참여하는 여가활동은 TV 시청이 가장 많고, 다음으로 친구들과 대화, 노인모임 활동, 걷기 및 산책, 친구 및 친척집 방문, 동물기르기 등의 순이었다. 둘째, 노인의 여가활동 유형은 적극적 자기 개발 활동, 소극적 자기개발 활동, 투기성 활동, 폐쇄형 활동, 안락한 고독활동, 우인중심 활동, 가족중심 활동, 종교활동의 8개 요인으로 분류되었다. 셋째, 노인들의 여가활동은 성, 연령, 월평균 수입, 교육수준 등이 통계적으로 유의한 관련이 있었고(P<0.05), 생활만족도와는 성, 연령, 월평균 수입, 교육수준, 건강상태 등이 유의한 관계가 있는 것으로 나타났다(P<0.05). 넷째, 노인의 생활만족도에 영향을 미치는 요인으로는 건강상태, 성, 월평균 수입, 여가활동, 의료보장 등이 통계적으로 유의한 변수로 선정되었다.(P<0.05) 따라서 노인의 삶의 질은 향상시키기 위해 제언을 하면 다음과 같다. 첫째, 건강상태가 생활만족도에 가장 관련이 있는 것으로 나타났으므로 만족스러운 노후생활을 위해서는 건강상태를 증진시키는 것이 요구된다. 이를 위한 방법으로 규칙적인 생활 체육을 장려하고, 노인전문 병원을 제도화 시키며, 가정 간호사업을 효율적으로 활성화 시키는 것이 바람직하다고 본다. 둘째, 월 평균 수입이 많을수록 생활만족도가 높은 것으로 나타났는데, 이는 소득 보장인 연금제도의 정착이 매우 중요한 문제임을 암시해 준다. 본 연구에서는 의료보호 대상자가 의료보험 대상자보다 생활만족도가 높았음을 볼 때, 규칙적이고 예측 가능한 수입은 생활만족도의 중요한 요인임을 유추 해석할 수 있다. 그러므로 경제적인 도움을 줄 수 있는 방법으로 노인들의 역할을 부여해 주는 것이 필요하다. 그 역할로는 장 담그기, 아기 돌보기, 김치감기, 봉투 만들기 등이 있을 수 있다. 끝으로 여가활동 참여를 많이 할수록 생활 만족도가 높게 나타났는데, 이를 위해 지역 주민과 더불어 노인이 함께 이용할 수 있는 복지센터를 설치하여야 한다고 본다. 또한 활용 가능한 인적, 물적 자원을 최대한 동원하여 여가 프로그램을 개발하고 발전시켜 나감으로써 노인의 적극적인 여가 활동 참여를 유도해 나가야 한다고 본다.

본 논문은 철학적 관점에서 게임에서 발생되는 가상자아와 가상신체에 대한 소프트웨어사이보그 특성의 변화에 관해 연구한 것이다. 사이보그개념은 넓게 보면 인간과 기계의 결합을 말하지만 구체적으로 들어가면 유기체인 인간과 보철물 같은 기계를 결합하는 하드웨어 사이보그와 인간의 뇌를 전자화시켜 가상신체로 전환시키는 소프트웨어 사이보그가 있다. 가상게임은 두 번째 소프트웨어 사이보그가 적용되는 사례인데, <언틸던>게임 같은 경우 일반적인 사이보그 개념과 다른 가상신체와 가상자아의 특징들이 보여 진다. 이런 특징들을 분석하기 위해 한스모라벡의 소프트웨어사이보그개념과 김선희의 사이버공간 속성과 다중자아개념을 적용하였다. 일반적인 가상게임은 뇌의 유형을 복제한 소프트웨어사이보그로써 가상세계의 속성 때문에 신체가 무효화되는 경향이 있었다. 그러나 <언틸던>게임 같은 경우 3인칭시점과 실존배우를 게임캐릭터로 제작한 점을 본다면 오히려 플레이어의 심리적 동일성을 유지하기 위해 사진 이미지적 사실성을 추구하면서 가상신체의 필요성을 역설하고 있는 것이다. 그리고 게임진행 중 플레이어는 8개의 캐릭터를 교차선택하면서 미션을 완수하게 되는데 이것은 현실자아가 다중자아로 복제되면서 겪게 되는 선택과 경험을 이용해 바람직한 최종엔딩을 이끄는데 큰 역할을 하게 된다. 이러한 사이버 다중자아는 현실세계의 다중자아들에게 비해 적극적이고 긍정적인 특징을 보여주면서 소프트웨어사이보그의 장점으로 부각될 수 있다. <언틸던> 게임의 특징은 최종엔딩이 플레이어의 선택에 따라 달라지고 등장인물간의 우정관계에 따라 친구의 생사가 결정된다는 점이다. 이때 가상자아는 시행착오를 통한 경험적, 도덕적, 직관적 선택의 기준을 자기 나름대로 설정하면서 바람직한 선택을 하려고 노력한다. 또한 다중자아들의 지식을 하나로 융합할 수 있어 한 단계 높은 정신적 성찰을 이루게 된다. 이런 과정은 세계에 대한 자신의 해석을 긍정하고 자기극복을 통해 정신적 성찰의 이루는 인간, 니체가 말한 위버멘쉬가 되는 과정으로 볼 수 있다.

역사상 한국과 동남아시아 국가의 교역은 활발하지 않았다. 한중일 동북아 중심의 역사 서술과 지리적으로 멀어 동남아 국가들에 대한 관심은 상대적으로 적었기 때문이다. 동남아 국가 중에 베트남은 한국 사신들과 교류가 많았다. 유권 문화권, 한자 문화권으로 정서가 통하고 언어 소통이 가능했기 때문이다. 한국과 베트남 양국은 서로 관심을 보여 왔으며 사신들의 활발한 접촉으로 국교 수립과 관계없이 문물이 전파되고 우호적 감정을 유지할 수 있었다. 19세기 전반 베트남의 가장 위대한 황제 중 한명으로 꼽히는 민망시대에 고려인삼은 지금의 한류처럼 인기를 끌었다. 142명의 자손을 둔 민망황제의 정력이 인삼에 기인한다고 믿었다. 민망황제는 공을 세운 신하나 연로한 신하에게 선물로 인삼을 하사하여 충성을 유도했다. 이같은 전통은 후대 황제에게 까지 이어졌다. 또한 태국, 캄보디아, 프랑스와의 전쟁에 파견된 장군 및 병사들에게도 인삼은 지급되었다. 베트남은 국가 이념강화에 인삼을 적극 활용했다.이 같은 전통으로 고려인삼은 베트남에서 프리미엄 인삼으로서 인식되었다. 인삼의 베트남 유입은 1) 중국 황제의 하사 2) 북경으로 조공을 간 베트남 사신의 구매 3) 사무역 4)국제 무역이 활발했던 류큐, 일본의 중계무역 5) 조선-베트남 사신의 교유 등 5가지 경로를 유추할 수 있다. 베트남이 인삼을 본격 구매하기 전에 인삼의 효능에 대한 인식이 먼저 있었을 것이다. 이는 교역으로서가 아니라 양국 사신들의 교유에서 정보를 얻을 수 있었을 것으로 보인다. 15세기에서 18세기 말까지 북경에서 조선과 베트남의 사신, 선비들의 활발한 교류가 이루어졌다. 1760년 북경에 온 베트남 고관 여귀돈이 조선사신에게 편지를 보내 고려인삼을 보내줄 것을 요청한 것은 18세기에 이미 베트남에서 고려인삼의 가치에 대한 인식이 높았음을 확인해준다. 양국 사신의 교유를 통해 상대 나라의 풍습과 특성을 파악하는 과정에서 베트남 황실에서도 인삼에 대한 지식을 쌓았을 것으로 보인다. 특히 북경으로 사행을 간 사신들 중에 인삼에 조예가 깊은 서거정, 서호수 등 실학자들이 많았음은 이를 뒷받침한다. 베트남에서는 신라 시대에 인삼에 대한 인식이 성립되었을 가능성도 배제할 수 없다. 9세기 중반 안남도호부의 책임자로 파견돼 베트남을 10년간 통치했던 당의 고병은 신라인 최치원과 친밀한 관계로 고병이 인삼에 대한 지식을 베트남 상류층에 전했을 수도 있다. 이로써 베트남의 인삼인식은 조선시대에 본격적으로 이루어졌지만 멀리는 삼국시대까지 거슬러 올라갈 가능성도 있다. 하지만 이 같은 베트남의 인삼 인식시기 추정은 양국의 접촉 과정에 유추한 가설로서 이를 문헌으로 실증해야 하는 과제가 남아있다. 특히 베트남의 역사서와 문집에서 인삼의 흔적을 찾는 연구가 진행되어야 한다.

In collaborative tagging systems such as Delicious.com and Flickr.com, users assign keywords or tags to their uploaded resources, such as bookmarks and pictures, for their future use or sharing purposes. The collection of resources and tags generated by a user is called a personomy, and the collection of all personomies constitutes the folksonomy. The most significant need of the folksonomy users Is to efficiently find useful resources or experts on specific topics. An excellent ranking algorithm would assign higher ranking to more useful resources or experts. What resources are considered useful In a folksonomic system? Does a standard superior to frequency or freshness exist? The resource recommended by more users with mere expertise should be worthy of attention. This ranking paradigm can be implemented through a graph-based ranking algorithm. Two well-known representatives of such a paradigm are Page Rank by Google and HITS(Hypertext Induced Topic Selection) by Kleinberg. Both Page Rank and HITS assign a higher evaluation score to pages linked to more higher-scored pages. HITS differs from PageRank in that it utilizes two kinds of scores: authority and hub scores. The ranking objects of these pages are limited to Web pages, whereas the ranking objects of a folksonomic system are somewhat heterogeneous(i.e., users, resources, and tags). Therefore, uniform application of the voting notion of PageRank and HITS based on the links to a folksonomy would be unreasonable, In a folksonomic system, each link corresponding to a property can have an opposite direction, depending on whether the property is an active or a passive voice. The current research stems from the Idea that a graph-based ranking algorithm could be applied to the folksonomic system using the concept of mutual Interactions between entitles, rather than the voting notion of PageRank or HITS. The concept of mutual interactions, proposed for ranking the Semantic Web resources, enables the calculation of importance scores of various resources unaffected by link directions. The weights of a property representing the mutual interaction between classes are assigned depending on the relative significance of the property to the resource importance of each class. This class-oriented approach is based on the fact that, in the Semantic Web, there are many heterogeneous classes; thus, applying a different appraisal standard for each class is more reasonable. This is similar to the evaluation method of humans, where different items are assigned specific weights, which are then summed up to determine the weighted average. We can check for missing properties more easily with this approach than with other predicate-oriented approaches. A user of a tagging system usually assigns more than one tags to the same resource, and there can be more than one tags with the same subjectivity and objectivity. In the case that many users assign similar tags to the same resource, grading the users differently depending on the assignment order becomes necessary. This idea comes from the studies in psychology wherein expertise involves the ability to select the most relevant information for achieving a goal. An expert should be someone who not only has a large collection of documents annotated with a particular tag, but also tends to add documents of high quality to his/her collections. Such documents are identified by the number, as well as the expertise, of users who have the same documents in their collections. In other words, there is a relationship of mutual reinforcement between the expertise of a user and the quality of a document. In addition, there is a need to rank entities related more closely to a certain entity. Considering the property of social media that ensures the popularity of a topic is temporary, recent data should have more weight than old data. We propose a comprehensive folksonomy ranking framework in which all these considerations are dealt with and that can be easily customized to each folksonomy site for ranking purposes. To examine the validity of our ranking algorithm and show the mechanism of adjusting property, time, and expertise weights, we first use a dataset designed for analyzing the effect of each ranking factor independently. We then show the ranking results of a real folksonomy site, with the ranking factors combined. Because the ground truth of a given dataset is not known when it comes to ranking, we inject simulated data whose ranking results can be predicted into the real dataset and compare the ranking results of our algorithm with that of a previous HITS-based algorithm. Our semantic ranking algorithm based on the concept of mutual interaction seems to be preferable to the HITS-based algorithm as a flexible folksonomy ranking framework. Some concrete points of difference are as follows. First, with the time concept applied to the property weights, our algorithm shows superior performance in lowering the scores of older data and raising the scores of newer data. Second, applying the time concept to the expertise weights, as well as to the property weights, our algorithm controls the conflicting influence of expertise weights and enhances overall consistency of time-valued ranking. The expertise weights of the previous study can act as an obstacle to the time-valued ranking because the number of followers increases as time goes on. Third, many new properties and classes can be included in our framework. The previous HITS-based algorithm, based on the voting notion, loses ground in the situation where the domain consists of more than two classes, or where other important properties, such as "sent through twitter" or "registered as a friend," are added to the domain. Forth, there is a big difference in the calculation time and memory use between the two kinds of algorithms. While the matrix multiplication of two matrices, has to be executed twice for the previous HITS-based algorithm, this is unnecessary with our algorithm. In our ranking framework, various folksonomy ranking policies can be expressed with the ranking factors combined and our approach can work, even if the folksonomy site is not implemented with Semantic Web languages. Above all, the time weight proposed in this paper will be applicable to various domains, including social media, where time value is considered important.

According to the results mentioned above, the fact is certain that there is a great need for sex education of adolescents. Therefore, it is desirable that the schools teach sexual physiology and normal positively and that sex education including hygien education be an independant course in the curriculums. Furthermore, it is essential that the schools should have enough nurse teachers to take up sex education, expand training opportunities for them and that they develop educational materials. Considering the unbalance of the level of sex educations between boys and girls, I want to suggest that all boys and girls have sex education evenly and lead happy lives by correction irrational thought about sex, that is to say, sex discrimination, Sex education programs, especially of middle school students, should be reexamined if it is to give the students effective and profitable knowledge about sex. In addition, the government should establish a policy of adolescents' sex education to have healthy opinions of sex settled nationwide.
