This study was attempted to assess the effects of a long term regular sex education on the knowledge about anatomy and physiology of human reproductive organs and the attitude toward sex of second grade high school girls. The study population included 1,678 high school girls(542 educated second grade girls, 972 not educated second grade girls and 164 pre-educated first grade girls) attending in 3 high schools located in Kyungnam province. The data was collected by guestionnaire to assess knowledge of sexual anatomy and physiology and the attitude toward sex from 21 to 24 December 1988. The results were as follows: Most of students (educated group 99.3%, not educated group 98.1%) agreed to necessity of sex education. Among students 70.8% did not talk about their sexual problems with their parents and 30.1% of educated group obtained spxual knowledge from their teachers. There were significant differences between level of knowledge on anatomy and physiology of reproductive organs, secondary growth spurt, V D, pregnancy and contraceptives of educated group and not educated group (P < 0.01). There was significant difference between positive attitude about sexual intercourse before marriage, artificial abortion and family planning slogan of educated group and not educat.ed group (P < 0.05, P < 0.01). There were significant differences between degree of agreement about acquaintance with the other sex, knowledge of acquaintance with the other sex, talk freely with friend, parent and teacher of educated group and not educated group (P < 0.05, P < 0.01). Statistics revealed that high school girls of not educated group had less knowledge about acquaintance with the other sex than educated group (P < 0.01).

The purpose of this study is to understand how a teacher's teaching can be changed while he or she teaches the same contents in different classes. The qualitative research method was used in this study. Data were collected from classroom observations, several in-depth interviews, and stimulated-recall interviews after each class. All the data were transcribed and analyzed interpretively, and then, the results of the analysis were checked by each participating teacher. The results are as follows: First, changes appeared in each class in terms of the teaching items, tools, sequence, and time, even though the same teacher taught the same contents. It showed that the teacher's teaching practice changed immediately and intuitively in class. Second, teachers tried to implement "exploratory teaching" or "move-testing teaching" to address the emerging problems during their teaching. They then reflected on and modified their own teaching. This type of change, which happened during the teaching practice, can be an example of "Reflection-in-practice." Thus, the results of this study can provide helpful insights into how teachers might adapt and reflect in their teaching. It suggests that teachers need to recognize their subconscious teaching changes and learn "Reflection-in-practice."

In this study, we propose the core factors and application of asymmetric virtual reality(VR) content in which head-mounted display(HMD) user and Non-HMD users can work together in a co-located space that can lead to various experiences and high presence. The core of the proposed asymmetric VR content is that all users are immersed in VR and participate in new experiences by reflecting widely a range of users' participation and environments, regardless of whether or not users wear the HMD. For this purpose, this study defines the role relationships between HMD user and Non-HMD users, the viewpoints provided to users, and the speech communication structure available among users. Based on this, we verified the core factors through the process of producing assistive asymmetric VR content and cooperative asymmetric VR content directly. Finally, we conducted a survey to examine the users' presence and their experience of the proposed asymmetric VR content and to analyze the application method. As a result, it was confirmed that if the purpose of asymmetric VR content and core factors between the two types of users are clearly distinguished and defined, the independent experience presented by the VR content together with perceived presence can provide a satisfactory experience to all users.

재미 한인들의 급격한 증가와 더불어 미국 간호학의 한인들에 대한 문화적 지식의 유입을 필요로 하게 하였다. 더구나 기존 연구들은 한인들이 질병을 비효율적이며 부적절하게 관리하는 것으로 보고하고 있어 이에 대한 연구의 필요성이 더욱 증가하였다. 기존 연구에 의하면 초기 이민 경험은 이민자들의 건강과 질병 관리에 크게 영향을 미치는 것으로 나타났다. 이 연구에서는 비평적 문헌 고찰을 통하여 초기 이민 경험이 재미 한인들의 질병관리에 어떻게 영향을 미치는지에 관하여 살펴보고 이에 근거하여 재미 한인들을 위한 적절한 간호의 방향을 제시하고자 했다. 의학도서 목록 전산망과 기타 문헌 자료를 이용하여 1966년부터 1995년까지의 의학, 보건학, 생물학, 심리학, 사회학 문헌들을 살펴보았다. 체계적인 문헌 고찰을 위하여 4개의 세부적인 주제 아래 문헌들을 구분하여 고찰하였다 첫째. 일반적인 이민자들의 초기 이민경험, 건강, 질병 관리가 고찰되었고. 둘째로 재미 한인들의 초기 이민 경험이 고찰되어졌으며, 셋째로, 재미 한인들의 건강. 질병관리가 고찰되어졌고, 마지막으로 이들을 위한 간호의 방향을 제시해 줄 기존의 간호 모델들이 고찰되어졌다. 문헌 고찰 결과, 재미 한인들의 부적절한 질병 관리는 그들의 초기 이민 경험들과 관련되는 것으로 나타났다 첫째 문화적으로 결정되어진 신념이나 태도들이 재미 한인들의 적절한 질병 관리를 방해하는 것으로 나타났다. 둘째, 재미 한인들도 본국인들과 마찬가지로 질병관리를 위해 현대의학. 한방, 무속, 민간요법을 사용하는 것으로 나타났는데. 한방의 사용이나 이러한 치료법들의 흔용은 한인들의 적절한 질병 관리를 방해하는 것으로 나타났다. 셋째, 문화적 차이, 언어장벽, 그리고 비언어적 의사소통의 차이점에서 오는 오해들이 재미 한인들의 질병 관리를 부적절하게 만드는 것으로 나타났다. 넷째, 이민생활에서 오는 여러 어려움들 또한 재미 한인들의 질병관리를 어렵게 만드는 것으로 나타났으며, 다섯째. 사회적 지지의 부족 역시 재미 한인들의 적절한 질병관리를 힘들게 하는 것으로 나타났다. 마지막으로 적절한 간호 모델의 부재가 이들을 위한 적절한 간호의 제공을 어렵게 하고 있는 것으로 밝혀졌다. 이러한 결과에 근거를 두고 초기 이민 적응기에 있는 재미 한인들에게 적절한 간호를 제공하기 위한 몇 가지 제안들이 제시되었다. 첫째, 이민자들에게 적절한 간호가 제공되기 위해서도 문화적 배경을 고려해야 하겠다. 문화적으로 적절한 간호를 위해서 간호 제공자들은 자신들의 문화와 다른 간호 대상자의 문화도 존중해 주어야 하며, 문화적으로 결정되어진 건강 신념들과 질병 관리 행태도 생명을 위협하지 않는 한 존중해 주어야 할 것이다. 또한 간호제공자들은 자문화 중심적인 사고방식에서 벗어나야 하며, 간호 대상자들의 상황을 총괄적으로 이해하여야 하고 이민자들의 어려움에 대해 공감을 가지고 간호를 제공하여야 하겠다. 둘째, 간호 제공자들은 한방에 관한 지식을 가지고 한 의학 혼용으로 인한 위험으로부터 간호 대상자를 보호하여야 할 것이다. 셋째, 문화적 차이나 자민족 중심적 사고방식으로 인한 오해를 막기 위하여 간호 제공자들은 간호 대상자와 자주 상호 교류함으로써 배우는 자세로 간호 대상자를 대하여야 할 것이며, 자신의 자민족 중심적인 사고방식을 인지하고 언어적, 비언어적 의사소통의 문화 집단별 차이를 앎으로써 오해의 소지를 줄여야 할 것이다. 넷째, 적절한 간호의 제공을 위하여 의사소통을 위해 대화만을 직접 번역해 주는 통역자와는 달리 문화적 배경까지도 이해하고 해석해 주는 문화적 통역자의 도움을 밟아야 할 것이다. 다섯째, 한국문화는 가족 중심적 문화이므로 간호 대상자의 혈연관계를 이해하고 그에게 크게 영향을 주는 가족원을 간호 중재에 참여시킴으로써 치료 효과를 높여야 할 것이다. 마지막으로 효과적인 간호를 위하여 재미 한인을 위한 적절한 간호 모델을 개발함으로써 체계적인 간호의 방향을 제시할 수 있어야 할 것이다.

This study compares the influence of perceived public opinion on Internet users' willingness to expression in real space with in cyber space. In real space, people who perceive their opinions as minority opinion are reluctant to express theirs publicly because of fear of isolation. But cyber space is the anonymous world. So we can expect that people express their opinions freely without the fear of isolation in this space. This study's results provide the support for our expectation. In cyber space, the minority perception group has as the high willingness to expression of their opinion about the abrogation of the Korean Family Rights Raw as the majority perception group. Both of in cyber space and in real space, it is the perception failure group that makes discrepancy in the willingness to expression. This group has the lowest willingness to expression in both space. However, the other predictors of willingness to expression in cyber space are similar to those in real space. Issue salience, Communication apprehension, and Age are the very significant predictors of willingness to expression in both spaces. Sex and ideology are significant predictors in real space, while the frequency of online conversation is the significant predictor in cyber space.

In order to provide quality services across international airports, airline personnel must rapidly and effectively develop and share knowledge. Combining components of adaptive structuration theory (AST) and media synchronicity theory (MST), a research framework was developed to convey three distinct stages of knowledge sharing. We use the grounded theory research method for the qualitative data collected from audio transcripts of employees learning how to use and work with company issued smartphones with push-to-talk functionalities. Data was collected from 33 operations personnel. The results of the content analysis are recorded for the elements of each of the three concepts of our research framework. During the social interaction stage, the content of the audio conversations shifts mainly from conflict management to task management; for media synchronicity, from quality to quantity; for productive outcomes, from efficiency to commitment. New insights are uncovered from our analysis of data from the field as users advance from learning how to use the mobile devices, to using the devices for managing knowledge for their work in the airline industry.

Although digital hearing aid algorithms have been developed to compensate hearing loss and to help hearing impaired people to communicate with others, digital hearing aid user still complain about difficulty of hearing the speech. The reason could be the quality of speech through digital hearing aid is insufficient to understand the speech caused by feedback, residual noise and etc. And another thing is masking effect among formants that makes sound quality low. In this study, we measured the masking characteristics of normal listeners and hearing impaired listeners having presbyacusis to confirm masking effect in speech itself. The experiment is composed of 5 tests; pure tone test, speech reception threshold (SRT) test, word recognition score (WRS) test, puretone masking test and speech masking test. In speech masking test, there are 25 speeches in each speech set. And log likelihood ratio (LLR) is introduced to evaluate the distortion of each speech objectively. As a result, the speech perception became lower by increasing the quantity of formant enhancement. And each enhanced speech in a speech set has statistically similar LLR, however speech perception is not. It means that acoustic masking effect rather than distortion influences speech perception. In actuality, according to the result of frequency analysis of the speech that people can not answer correctly, level difference between first formant and second formant is about 35dB, and it is similar to result of pure tone masking test(normal hearing subject:36.36dB, hearing impaired subject:32.86dB). Characteristics of masking effect is not similar between normal listeners and hearing impaired listeners. So it is required to check the characteristics of masking effect before wearing a hearing aid and to apply this characteristics to fitting.

The purpose of this study was to investigate the gifted students' view on argumentation and the aspects of the argumentation in problem-solving type experiment. As a result, very lively argumentation was identified but quality enhancement on argumentation wasn't found over time. Students made frequent use of dialogic argumentation component, and especially, request & response component was highly used. Though usage frequency is low, the component of ground & question on ground was shown in 3rd class, and simple agreement gradually reduced, and reinforcing elaboration & metacognitive question has slightly increased. Also, students' argumentation were closely related to teachers' teaching approaches as some teacher-led steps doesn't appear in students' argumentation. By comparison in steps, 'problem solving activity & result analysis' step included 2 times more argument components than the previous step. We also found that method grouping teams does not almost affect the argumentation of gifted students. By survey results, most students recognized that they experienced free argumentation and this program activate argumentation and 'strange things' or 'difficulty' of program topics are obstacles in vitalization of argumentation. 'Surface growth experiments' was the most lively argumentation topic. The argumentation was lively made in the step of 'finding solution. 'Teachers' scaffolding accelerate the argumentation and help resolve difficulties in argumentation. Thus, students have positive recognition for the argumentation process in the experiments and recognize that argumentation process is needed.

As a case study on the changes of beginning science-gifted education teachers' teaching professionalism through coteaching, this study deeply investigated the change processes in the aspects of pedagogical content knowledge. We selected two beginning teachers whose teaching careers in secondary science-gifted education were less than five years. The teachers planned, performed, and reflected together their science instructions for secondary science-gifted students during nine class hours over three times. We observed coteaching of science instructions of the teachers, and analyzed the taped videos, the materials, the transcripts for discussions between them and in-depth interviews with them, their reflective journals, and researcher's field notes by using the constant comparative method. This study revealed that the coteaching positively changed the two teachers' practical knowledge about the curriculum for science-gifted education, the instructional strategies for science-gifted education, the assessment in science-gifted education, the science-gifted students, and the science contents although there were some limitations. The results suggest that the coteaching will be useful in improving beginning teachers' teaching professionalism, and provide practical implications in finding the ways to use it effectively in science-gifted education.

The purpose of this study is 1) to survey to identify how high school students think about career guidance and job and 2) to pursue effective career guidance. According to the survey result, first, most students have thought about their career. They chose friends as a counselor for their future. Among respondents, 39.84% of them said they did not consult with teachers. They said academic record is a stumbling block in choosing career. Second, many students responded career guidance should start at 'Junior High school'. 76.56% of respondents said they were lack of career guidance resources. With respect to career, an important subject was shown as the following order: social study, English, Korean, Science and Math. Third, students recognized the face that aptitude and ability should be the utmost important factors in choosing career. They chose mass media as a main source to gain information relative to career, which accounted for 52.34% and 20.31% for teachers. In the case of students who have rather 'poor'home background, teachers were the main sources for career information, whose proportion was relatively high. Forth, parents were the most influential people who helped students choose which high school to go(40.69%). In terms of scope of higher education, 65.63% said they wanted to graduate university. Students who has good academic records and good home environment wanted to pursue Master's or Doctor's degrees. 70.31% of respondents said they attended a high school just because they wanted to have a desired job.
