  • The poxvirus group is considered to be a typical cytoplasmic inclusion forming virus. Every poxvirus has been reported to produce only one kind of inclusion in the infected tissues. A vague concept that inclusions of poxviruses are eosinophilic or acidophilic has prevailed. Although many papers and theories about the nature of the inclusion have been presented, most of them are not quite convincing on the point of the relations with virus multiplication, and an analysis of papers published showed that there seem to be many discrepancies in the descriptions of the nature of the poxvirus inclusions. Comparative studies on host-virus interaction with cowpox, orf, swinepox and fowlpox viruses which selected from each Group (I-IV) of poxviruses were performed from the morphological and virological standpoints. At first, in cowpox virus-FL cell system, as a comparative model, cytoplasmic inclusion, nucleic acid metabolism by autoradiography and detection of viral antigen by immunofluorescence were studied and obtained the results as follows: 1. The focus-like cytopathic effect (CPE) at early stage developed to entire culture at terminal stage of infection, and also the developing status of CPE was correlated to viral doses for inoculation. Two kinds of cytoplasmic inclusions which named A and B type were easily observed by Giemsa, hematoxylin-eosin (H & E) and May-Greenwald Giemsa (MGG) stainings in the infected cells. The B type inclusions were formed at early stage of infection and the A type inclusions were produced subsequently the B type formation. The B type which common type inclusion in poxviruses was a small compact or aggregate at early stage and developed to a large diffuse body at terminal stage of infection. On the other hand, the A type inclusion which depend upon the kind of virus was appeared as round and discrete shape, and its size and number was increased gradually during the culture period. It was characteristic to form distinct halos around the both types of inclusions in acid fixed, H & E stained preparations of infected cultures. The B type inclusion was always positive in Feulgen reaction and showed as DNA containing body but the A type inclusion was not. 2. In the relationship between inclusion and DNA metabolism of infected cells by the qualitative autoradiography using 3H-thymidine, the appearance of silver grains was coincided with B type inclusion but not with A type inclusion. This showed that the DNA synthesis was proceeded in all B type inclusions except those in the terminal stage with a diffuse form. This suggested that the B type inclusions are only sites of DNA synthesis and this was proceeded after the cell infection independently. The activity of DNA synthesis of the inclusions was nearly the same as that of the nucleic of normal cells and non-inclusion bearing cells. and non-inclusion bearing cells. Regardless of the size of the degree of DNA synthesis of the B type inclusion, inclusion bearing cells all showed remarkable suppression of nuclear DNA synthesis. 3. By the direct fluorescent antibody technique viral antigen in infected cells was detected. The B type inclusions have been proved to contain a great deal of viral antigen, whereas the basic substance of A type inclusion did not show antigenicity except the round edge. It was suggested that the round edge fluorescence might be caused by the glare of cytoplasmic viral antigen which pushed out and concentrated by the A type inclusion development. 4. Hemorrhagic red pock formations on chorioallantoic membrane of embryonated chicken egg had proved the characteristic of used viral strain. 5. By the above studies on the nature of two types of inclusions and the role they play in virus multiplication, it was concluded that the B type inclusion must be the site of the synthesis of viral DNA and protein as well as the site of the virus.

  • With the advent of communication technologies including electronic collaborative tools and conferencing systems provided over the Internet, virtual collaboration is becoming increasingly common in organizations. Virtual collaboration refers to an environment in which the people working together are interdependent in their tasks, share responsibility for outcomes, are geographically dispersed, and rely on mediated rather than face-to face, communication to produce an outcome. Research suggests that new sets of individual skill, knowledge, and ability (SKAs) are required to perform effectively in today's virtualized workplace, which is labeled as individual virtual competence. It is also argued that use of online social networking sites may influence not only individuals' daily lives but also their capability to manage their work-related relationships in organizations, which in turn leads to better performance. The existing research regarding (1) the relationship between virtual competence and task performance and (2) the relationship between online networking and task performance has been conducted based on different theoretical perspectives so that little is known about how online social networking and virtual competence interplay to predict individuals' task performance. To fill this gap, this study raises the following research questions: (1) What is the individual virtual competence required for better adjustment to the virtual collaboration environment? (2) How does online networking via diverse social network service sites influence individuals' task performance in organizations? (3) How do the joint effects of individual virtual competence and online networking influence task performance? To address these research questions, we first draw on the prior literature and derive four dimensions of individual virtual competence that are related with an individual's self-concept, knowledge and ability. Computer self-efficacy is defined as the extent to which an individual beliefs in his or her ability to use computer technology broadly. Remotework self-efficacy is defined as the extent to which an individual beliefs in his or her ability to work and perform joint tasks with others in virtual settings. Virtual media skill is defined as the degree of confidence of individuals to function in their work role without face-to-face interactions. Virtual social skill is an individual's skill level in using technologies to communicate in virtual settings to their full potential. It should be noted that the concept of virtual social skill is different from the self-efficacy and captures an individual's cognition-based ability to build social relationships with others in virtual settings. Next, we discuss how online networking influences both individual virtual competence and task performance based on the social network theory and the social learning theory. We argue that online networking may enhance individuals' capability in expanding their social networks with low costs. We also argue that online networking may enable individuals to learn the necessary skills regarding how they use technological functions, communicate with others, and share information and make social relations using the technical functions provided by electronic media, consequently increasing individual virtual competence. To examine the relationships among online networking, virtual competence, and task performance, we developed research models (the mediation, interaction, and additive models, respectively) by integrating the social network theory and the social learning theory. Using data from 112 employees of a virtualized company, we tested the proposed research models. The results of analysis partly support the mediation model in that online social networking positively influences individuals' computer self-efficacy, virtual social skill, and virtual media skill, which are key predictors of individuals' task performance. Furthermore, the results of the analysis partly support the interaction model in that the level of remotework self-efficacy moderates the relationship between online social networking and task performance. The results paint a picture of people adjusting to virtual collaboration that constrains and enables their task performance. This study contributes to research and practice. First, we suggest a shift of research focus to the individual level when examining virtual phenomena and theorize that online social networking can enhance individual virtual competence in some aspects. Second, we replicate and advance the prior competence literature by linking each component of virtual competence and objective task performance. The results of this study provide useful insights into how human resource responsibilities assess employees' weakness and strength when they organize virtualized groups or projects. Furthermore, it provides managers with insights into the kinds of development or training programs that they can engage in with their employees to advance their ability to undertake virtual work.

  • This study is carrying out a before and after experiment design for the non-equal comparative group to identify the effects of the breast self-examination education on breast self-examination participant education compliance and health promotion in women. The subject of this study was 58 women residing in Chungju. Their age ranged from 20 to 40. These women were not pregnant or did not breast feed, as well as they did not have any breast disease, at the time of survey. They were available for the response to the questionnaires, and understood the purpose of this study. They also agreed to participate in the study, and responded to the 3rd time questionnaires to the end. Thus, brochures and lectures were provided side by side to a group of 19 of those women, and only brochures were provided to another group of 39 of those women. With regard to education, a brochure and a program using a breast model were applied. Then, the frequency of the breast self examination compliance, breast self examination capability and the relations between the breast self examination and activities to promote health were measured, before the education, after 4 weeks of education and after 12 weeks of education. Before education and after 4 weeks of education. I collected the questionnaires myself visiting them, and after 12 weeks of education, the questionnaires were collected by mail. In relation to the study tool, the breast self examination activity was measured by two measuring tools: breast self examination activity frequency and breast self examination compliance capability. As for the frequency, the number of self examination for the period of 3 months, before the questionnaire survey, was measured in the form of self report. In relation to the tool to measure the breast self examination capability, the BSEPRI tool, which was developed by Wood in 1994, was used. Here, as the score was higher, the capability was indicated to be higher. The translated and revised version of Health Promoting Lifestyle Profile II (Walker, Sechrist & Pender. 2002) was used as a tool for health promotion. As the measured score was higher, the health promoting activity was indicated to be higher. The results of this study were as follows: 1. As a result of checking the breast self examination compliance frequency between the experiment group that received the breast self examination participant education and the comparative group that did not receive the education, there was a significant difference in interaction between groups by time, as time passed by. 2. As a result of checking the breast self examination compliance capability between the experiment group and the comparative group, there was a significant difference in interaction between groups by time, as time passed by. 3. As a result of carrying out a repetitive measurement analysis, between the experiment group that received the breast self examination education and the comparative group that did not receive the education, which was carried out to validate the hypothesis that the former would have higher health promoting activities than the latter, there was no significant difference after the breast self examination education was conducted.

  • 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.

  • 김해지역의 덕봉납석광상은 모암이 안산암질응회암과 안산암으로 구성된 백악기말기의 화산암류가 열수변질작용을 받아서 형성되었으며, 딕카이트와 엽납석이 주구성광물이다. 이 연구에서는 산출하는 광물의 특성과 모암의 열수변질작용을 규명하고, 광물과 열수용액 간의 반응관계를 통하여 광상의 성인을 밝히고자 한다. 암석 내의 화학적 특성을 보면 열수변질작용동안 알칼리원소와 실리카는 유동성을 보이나 알루미나는 비교적 유동성이 작다. 모암으로부터 실리카의 용탈과 알루미나의 부화로 인하여 납석광체가 형성되고, 외곽부로 이동된 실리카의 재침전이 규화대를 생성시켰음을 볼 수 있다. 딕카이트와 엽납석과 밀접히 수반되는 다량의 미정질의 석영은 실리카의 활동도가 증가함에 따라서 형성된 것으로 해석된다. Argillic 변질대에서는 열수용액의 실리카의 용해도가 증가하였고, 규화대에서는 온도와 pH가 저하되면서 그 용해도가 저하되었다. Argillic 변질대로부터 빠져나간 Si는 광상의 가장자리에 침전하여 규화대를 형성시켰다. 딕카이트가 다양한 범위의 결정도를 보여주는 것은 계내의 부분적인 상안정성의 변화를 시사한다. 이 연구에서 계산된 열역학 값에 따르면, $Al_{2}O_{3}-SiO_{2}-H_{2}O$ 계에서 엽납석-딕카이트 (카오리나이트)-다이아스포아-석영이 500 바에서 공존가능한 온도는 약 300 $^{\circ}C$이다. 광물조합과 기존실헙자료를 종합하면 주요 열수변질 시기의 온도는 최소한 270-300 $^{\circ}C$이며 $X_{CO_2}$는 0.025 미만으로 추정된다. 광물의 산상과 화학적 변화양상에 따르면 Al의 활동도는 광상의 상부에, 그리고 Si의 활동도는 하부와 연변부에서 높음을 보여준다. 덕봉광상에서 흔히 관찰되는 비평형 상관계는 열역학적 변수와 용액운반특성의 국부적인 변화로 인하여 화학적으로 비평형인 상들이 여러 단계에 걸쳐 형성되었음을 지시한다.

  • 본 연구는 단지 지명도 부족과 관광 여건의 변화에 따른 홍보 전략용으로 급조, 지정된 신영월십경 지정에 따른 문제의식에서 출발하여 영월의 관광 문화자원의 대부분이 단종과 관련되어 었다는 사실에 착안하였다. 이에 따라 익히 알려진 '단종에 대한 슬픈 역사'와 유배지 영월의 문화자원이 갖는 지명도 등의 후광효과를 통해 미개발 관광콘텐츠 영월팔경의 형식과 내용을 검토하여 "문화경관 영월팔경"이라는 경관콘텐츠의 스토리텔링 방안을 제시하고자 하였다. 본 연구에서는 영월팔경이라는 문화경관 텍스트와 <단종애사> 라는 역사콘텐츠의 조응적 관계성 모색을 통한 장소와 역사적 현장 경관의 동일성을 통한 의미와 이야기 전달과정에 주목하였다. 이를 위해 영월의 자연문화경관을 공간적 텍스트화하기 위한 틀 짜기(framing)와 켜 짜기(layering)를 시도하였다. 그리고 스토리뿐만 아니라 텔링이 텍스트 향유의 지배적 요소가 되도록 하기 위한 에피소드 등의 이야깃거리를 탐색하고 경관 주제의 모티브로 발굴하고자 하였으며, 한편으로는 스토리텔링 방식을 다양화시키기 위한 방안으로 텍스트의 구조 안에서 재맥락화가 이루어질 수 있도록 몰입 경관요소를 장소, 대상 그리고 시점으로 구분하여 현장화 하였다. 또한, 경관 몰입요소를 인포테인먼트(Infortainment)와 에듀테인먼트(Edutainment) 요소 등의 미시 콘텐츠를 제시함으로써 '영월팔경-단종애사'의 이야기성, 현장 장소성 그리고 다양한 문화콘텐츠를 공유하기 위한 상호관계성을 고려한 영월팔경 스토리텔링 전략을 제시하였다. 제안된 스토리텔링 방안이 실제 영월 관광의 대안이자 전략으로 실용화되기 위해서는 경관 연출의 리얼리티를 역동적으로 재구성하기 위한 시점의 설정과 경관 루트 연계방안 그리고 내레이션 시나리오가 갖추어져야 하며, 영월의 자연 및 풍수적 관점에서의 형국 인식과 단종 관련 역사에 대한 충분한 이해를 기반으로 한 경관해설가의 양성이 필요하며 인터넷과 디지털상용화 전략이 병행되어야 할 것으로 본다.

  • 본 논문에서는 국제공동연구인 DECOVALEX-2019 프로젝트 Task B의 연구결과와 현황을 소개하였다. Task B의 주제는 'Fault slip modelling'으로 유체의 주입으로 인해 발생하는 단층의 재활성(미끄러짐, 전단파괴)과 수리역학적 거동을 예측할 수 있는 해석기법을 개발하는 데에 그 목적이 있다. 1단계 연구는 참가팀들이 연구주제에 대해 숙지하고, 벤치마크 모델을 대상으로 단층의 투수특성과 역학적 거동의 상호작용을 모사할 수 있는 해석코드를 개발할 수 있도록 하는 준비 단계의 연구이다. 본 연구에서는 TOUGH-FLAC 연동해석 기법을 사용하여 물 주입으로 인한 단층의 수리역학적 연계거동을 모사하였다. TOUGH2 해석에서는 단층을 Darcy의 법칙과 삼승법칙을 따르는 연속체 요소로 모델링하였으며, FLAC3D 해석에서는 미끄러짐과 개폐가 허용되는 불연속 인터페이스 요소를 통해 모사하였다. 두 가지 수리간극모델에 대하여 수리역학적 커플링 관계식을 수치화하였으며, 연속체 요소(수리모델)와 인터페이스 요소(역학모델)의 거동을 연계할 수 있는 해석기법을 제시하였다. 또한, 단층의 역학적 변형(간극의 변화)으로 인한 수리물성 변화와 기하학적 변화(해석 메쉬의 변형)를 수리해석에 반영할 수 있는 해석기법을 개발하였다. 다양한 압력의 물을 단계적으로 주입하고 이로 인해 유도되는 단층의 탄성거동 및 전단파괴(미끄러짐)에 대해 살펴보았으며, 수리간극의 변화 양상과 원인, 압력 분포와 주입율의 관계 등을 면밀히 검토하였다. 해석 결과, 본 연구에서 개발한 해석기법이 물 주입으로 인한 단층의 미끄러짐 거동을 합리적인 수준에서 재현할 수 있는 것으로 판단할 수 있었다. 본 연구의 해석모델은 Task B에 참여하는 국외 연구팀들과의 의견 교류와 워크숍을 통해 지속적으로 개선하는 한편, 향후 연구의 현장시험에 적용하여 타당성을 검증할 예정이다.
