Information types and display methods according to the relation between frequency of exposure and degree of cognition was suggested by this study as a way to enhance effective communication by information in aspect of user cognition. First of all, we ascertained the relation between frequency of exposure and degree of cognition by literature research for cognitive psychology and cognitive engineering psychology, results are as follows based in it. First, we suggested information types and attributes for visualization as 'Framework' which helps designers understand cognitive demands of users. Specifically, there are 4 types(STM, STA, LTM, LTA) of information according to the relation between frequency of exposure and degree of cognition, cognitive characteristics for each types and 'attributes matrix for visualization' which is consisted of 14 attributes of high -quality information and resorted by the types. Second, we suggested a guideline for display methods according to depth of information in the design process of information contents. For display methods of STM, STA information as primary information, we suggested "Attribution theory of Distinctiveness", "Advance Organizer", "Progress Closure", "Affordance", for display methods of LTM information as multidimensional information, we suggested "Modularity", "Consistency", "Mimicry", "Mnemonic Device". We had found from this study that there are distinction of status for attributes of information visualization according to information types or depth, and various display methods by them.

We described a spatial distribution pattern and floral diversity on the Paspalum distichum community occurring at the ecological parks of Hwamyeong, Daejeo, Samnak, and Maekdo in the Nakdong river estuary. A total distribution area of P. distichum community was $303,462.6m^2$. Its largest area was found in Samnak eco-park ($185,910.1m^2$). The most richness of knotgrass patches in each ecological park was determined Maekdo eco-park (87). Cover class level-5 shows the largest area ($260,663.2m^2$). A total of 73 taxa (34 families, 55 genus, 65 species, and 8 varieties) were listed up on the P. distichum community. A welldeveloped population of knotgrass was found predominantly at sites linked into human impacts at the riverine floodplain, the stream courses flowing through the parks, and the man-made channels and wetlands. Finally we proposed an ecological management strategy for knotgrass population in the study area.

In this study, the HEC-GeoRAS model was used to estimate the changes of flood inundation depth and area of the Hyeoam-cheon basin after the channel migration and river improvement. The target area was extremely damaged due to the heavy rainfall on 25th August, 2014 after the costruction. According to the results of the analysis, the HEC-GeoRAS model can be used to accurately estimate the changes of flood innundation depth and area in agrecultural lands and lowlands of which the topographic changes and elevation differences are small. The inundation depths were increased 0.99 m in heavy rainfall and 0.39 m in 100 year frequency flood. The inundation areas in 100 year frequency flood were reduced in inundation depths under 1.5 m while they were increased in depths above 4.5 m. It was concluded that the loss of natural resevoir capacity of agricultural lands and lowlands due to the channel migration and river improvement caused the damage of flood in 2014 and the decrease of actual effective widths of the channel added the damage.

유비궈터스 헬스케어는 단일화된 서비스가 아니라 다양한 기술들이 복합적으로 결합되어 운용되는 서비스이다. 따라서 서비스의 형태가 고정적이지 않고 매우 다양하게 나타난다. 하지만 실제로 차이가 발생하는 부분은 서비스의 구현에 관한 세부적 내용에서 나타나고, 서비스 운용을 위한 기본 구성요소에 있어서는 큰 차이가 없이 유사한 형태를 가진다. 그 결과 유비쿼터스 헬스케어 서비스 개발 과정에서는 실제 서비스의 구현 외의 통신과 데이터베이스의 이용, 메시지 전달과 같은 중복되는 항목에 대한 고려가 매번 이루어져야 한다. 이것은 개발 과정에 있어 불필요한 비용의 증가를 불러온다. 본 논문에서는 이와 같은 불필요한 비용을 감소시키며 서비스의 개발과 운용이 가능한 유비쿼터스 헬스케어 서비스의 제공을 위한 아키텍처와 서비스 개발을 위한 프레임워크를 제안한다. 제안하는 서비스 제공 아키덱처는 크게 이용자 단말, 유비궈터스 헬스케어 서비스 센터, 외부 기관으로 구성된다. 서비스 개발 프레임워크는 서버와 클라이언트 프레임워크로 구분된다. 서비스 개발 프레임워크는 서비스를 제공하는 서버에서 필요한 유비쿼터스 헬스케어 서비스의 공통 구성요소를 가진다. 서비스의 개발을 위해 우선 프로세스에 대한 정의를 수행하고, 정의된 내용에 따라 필요한 코드 템플릿을 결합하여 서비스의 초기 형태를 만들어낸다. 여기에 각 서비스가 필요로 하는 세부 사항을 작성하는 것으로 서비스의 개발을 수행하게 된다. 제안된 서비스 제공 아키텍처와 서비스 개발 프레임워크를 실제 적용해보기 위해 전림선비대증 환자 진료를 위한 시스템을 설계하고 구현하였다.JSHOP2 계획수립기내에 구현하였다. 계획 실행 방법으로는 주어진 강건한 계획에 대하여 행위들이 직접 실행하수 있도록 한다.며 용량에 의존하는 양상을 보였다. $H_2O_2$에 의해 유발(誘發)된 DNA의 손상은 catalase와 deferoxamine에 의해 억제되었지만 DPPD는 억제시키지 못했다. 배기음(排氣飮)은 $H_2O_2$에 의해 유발(誘發)된 ATP의 소실을 회복시켰다. 이러한 실험결과 $H_2O_2$에 의해 유발(誘發)된 세포(細胞)의 손상(損傷)은 지질(脂質)의 과산화(過酸化)와는 다른 독립적인 기전에 의해 일어남을 나타낸다. 결론 : 이러한 결과들로 볼 때 Caco-2 세포(細胞)에서 배기음(排氣飮)이 항산화작용(亢酸化作用)보다는 다른 기전을 통하여 Caco-2 세포안에서 산화제(酸化劑)에 의해 유발(誘發)된 세포(細胞)의 사망(死亡)와 DNA의 손상(損傷)을 방지할 수 있다는 것을 가리킨다. 따라서 본 연구(硏究)는 배기음(排氣飮)이 반응성산소기(反應性酸素基)에 의해 매개된 인체(人體) 위장관질환(胃腸管疾患)의 치료(治療)에 사용할 수 있을 가능성(可能性)이 있음을 제시하고 있다.에 이를 이용하여 유가배양시 기질을 공급하는 공정변수로 사용하였다 [8]. 생물학적인 폐수처리장치인 활성 슬러지법에서 미생물의 활성을 측정하는 방법은 아직 그다지 개발되어있지 않다. 본 연구에서는 슬러지의 주 구성원이 미생물인 점에 착안하여 침전시 슬러지층과 상등액의 온도차를 측정하여 대사열량의 발생량을 측정하고 슬러지의 활성을 측정할 수 있는 방법을

This research examines the recent increasingly intensified non-reporting phenomenon by the press in South Korea and its legitimacy and validity. Non-reporting denotes cases in which the press does not report on significant issues in society. Although journalism scholars have raised this question, it remains unaddressed through case studies and formal criticism. This research compares the reporting and non-reporting by major media groups of cases related to the surveillance of civilians by the National Intelligence Service and the Defense Security Command under the Ministry of National Defense. This research specifies that the non-reporting phenomenon relates not to the ability to report, but to willingness to report, due to intervention by political factionalism of media groups. The non-reporting phenomenon results from the press ignoring their basic responsibility stemming from journalistic ethics and their social responsibility to fulfill their readers' right to know. Accordingly, this research revealed that the non-reporting phenomenon cannot be justified through diverse theoretical discussions and the journalistic code of ethics. Through the logical framework of public opinions and diverse empirical data to support it, this research demonstrates that the non-reporting phenomenon produces not unhelpful, but harmful effects to resolutions to ideological dissent in South Korean society.

This study observes reporters' awareness on the use of social media and their Core Values by using the Theory of Means-End Chain and drawing conclusions from a Hierarchical Value Map (HVM). In order to analyze reporters' knowledge and awareness on the use of social media via the laddering method, in-depth interviews of 46 reporters were conducted. The study showed that reporters consider sense of kinship, well-balanced understanding, and the desire for knowledge to be important Core Values. The results revealed that the convenience in interpersonal communication, development of intimacy in relationships, entertainment and affection, curiosity, the reduction in the cost of the acquisition of information, understanding of trends in issues, a peek into new information and the maintenance of interests, psychological dependability, and quick updates on information items are considered important Consequences of social media. In the Attributes level, the ability to write postings and links on Facebook and readability and 'follow' and 'mention' features on Twitter were confirmed to be important items in social media. The findings infer that reporters that make use of social media use Twitter and Facebook to build a sense of kinship with other users and gain well-balanced understanding by accessing a lot of information through social media. While this study examined the level of reporters' familiarity with the use of social media via the laddering method, the results cannot be seen as a generalization, as the interviewees were reporters from only the major news organizations.

As knowledge workers have increased and information interchanges become more diverse, only the resources of internal enterprise is not longer useful, and the practical use of external information through information public sharing network is even more crucial. But, few studies that use both internal and external information sharing systems together have been conducted. In this research, we carried on the depth interview to analyze the main factors that intend to utilize outside information as well as to share inside information voluntarily. In conclusion, sharing internal information is directly involved with the performance of their job exchanging simple data, past documents, and technical materials. On the other hand, using the external information belonged to several other organizations is mostly caused by the voluntary participants' satisfaction sharing their individual experience through the network systems. Based on the study, we propose the idea that can activate both internal and external information sharing network through the system with user feedback function regarding the customized information, and with the space expansion where people can freely raise their private opinion. We also introduce the plan of the construction of communication systems with various experts, and the development of compatible devices with diverse interfaces.

Despite orthodontic treatment(tooth moving) is dynamic act many orthodontists have used mainly static evaluation method for evaluating effectiveness of the orthodontic appliances. They want to find which is better appliance, especially in the treatment results and treatment period when they chose one appliance from sugessted appliances for obtaining same treatment goal. The author and colleagues invented and manufactured new machine for getting information about the relative effectiveness from many suggested orthodontic appliances and we named it Calorific machine. We used this Calorinc machine to find the relative differences about tooth moving mechanism and tooth moving time between the Burstone's PLA(single force mechanism) and Molar-up's PLA(couple mechanism) for correcting the posterior cross bite. We measured the distance of tooth moving on the occlusal X-ray film and recorded the moving time of the anchored(control elctro-thermal tooth) and lingually tipped lower second molars(experimental electro-thermal tooth) and then processed paired t-est by SAS program. The results were as follows. 1. Molar-up's PLA showed more extrusive and horizontal movement than Burstone's PLA at the lingually tipped molar(p=0.0000). 2. There is no finding of tooth movement by Molar-up's PLA at the uprighted molar(p=o.3475) but Burstone's PLA showed a little change(0.2 m) at the same molar(p=0.0001). 3. Burstone's PLA took 17.8 minutes for tooth moving but Molar-up's PLA took only 3.8 minutes(p=0.0001)

본 연구는 광복 이후 현재까지 첫돌 복식 변화를 시대적으로 고찰, 그 변화 양상과 영 향 요인을 규명하는 것을 목적으로 하고 있다. 연구 방법은 문헌 고찰과 사진 자료를 통한 내용 분석을 주로 하였다. 더불어 자료의 보충을 위해 첫돌 의례와 관련된 주변 인물들-가족, 기성 아동 한복 유통 상인, 상업적 사진사 등-의 면접 조사도 병행하였다. 이상의 연구를 통해 다음과 같은 결과를 얻었다. 1940년대 중반∼50년대 초에는 해방 이후 혼란과 전란으로 인한 물자의 부족으로 첫돌 의례의 명분은 남아있으나 복식 문화는 공백기를 맞는다. 1950년대 중반이후 60년대 전반기는 미국의 경제 원조와 섬유 공업 활성화로 의료의 공급이 원활하여 전기에 비해 의례적 의미를 지닌 첫돌 복식의 착용이 가능해 졌다. 전통 한복을 기본으로 한 위에 서양식 복식 품목들이 섞여서 나타나고 있다 60년대 후반에서 1970년대의 두드러진 양상은 기성복 산업 의 발달로 전문적 인 기성복 시장이 형성되었고 이는 기성복화 된 첫돌 복식의 일습 개념을 등장시키게 하였다. 또한 한복이 예복화 되는 경 향이 두드러지게 나타났던 시기로 70년대 후반의 칼라 필름의 보급은 금박과 자수와 같은 다양한 재료와 재단 방법을 사용한 장식화 된 첫돌 복식의 사용을 가속화 시 켰다. 특히 70년대 중반에 소수의 일반에게 입혀졌던 궁중복식의 하나인 당의가 소매없는 당의로 바뀌어 여아의 돌옷으로 입혀지기 시작하였다. 1980년대 전반기는 칼라 TV의 보급, 비디오 촬영의 보편화로 한복이던 양복이던 일습화 된 첫돌 복식이 대중적으로 정착하게 되었다. 후반기에는 국내의 국제적인 행사의 유치와 전통 복식 소개를 위한 전시들을 계기로 왕실 복식에 대한 관심이 고조되었다. 이로 인해 여아에게 소매없는 당의를 입히고 남아에게 용포를 입히는 유행이 가속화되었다. 또한 서양식 예복을 입히는 유행이 시작되었다. 90년대에 들어와 아기 전문사진점의 등장은 1 회적인 첫돌 의례에 한복과 서양식 예복, 일상복 등을 다양하게 착용시키는 계기를 가져오게 하였다. 이상과 같은 다양한 변화 양상에도 불구하고 첫돌을 기념하기 위해 특별한 옷을 마련하고자 했으며, 그 복식의 구성 이 전통적인 일습 개념을 꾸준히 지향해 온 경향을 보여주고 있다. 반면 최근 과열된 아동 산업은 보다 다양한 복식을 입혀서 촬영한 사진으로 특별하게 꾸민 상업적인 기념물들을 남겨주게 하고 있다. 비록 특별한 옷을 준비하여 아동에게 입히는 행위는 유사한 표현 양태이나 지나치게 많은 옷을 갈아 입히는 표현 방식은 지양되어야할 것이다

In a recent period, it becomes more and more important to keep the cutting-edge industrial technology secured. This is because competitive technology appears to be a cornerstone of national power. Although the industrial espionage must be an illegal behavior or a kind of white-collar crime, there has been few researches on industrial espionage from a criminological perspective. This study investigates the relationship between industrial espionage, self-control, and organizational commitment. The hypotheses of this study were found to be statistically significant. The hypothesis 1 that the high self-control reduces the possibility of industrial espionage was accepted, and the hypothesis 2 that the high organizational commitment reduces the possibility of industrial espionage was also accepted. This results showed that self-control and organizational commitment were the key factors to prevent industrial espionage, which eventually reinforces industrial security. This study used a convenient sampling, which might be the limits of this study. By using a convenient sampling, the result of the study could not depend on representative sample. Nonetheless, this study was trying to explore the relationship between industrial espionage, self-control, and organizational commitment which was not researched yet. The purpose of this study is to contribute to find out the criminological causes of industrial espionage and eventually to prevent it.
