디지털미디어의 상호작용은 기능 중심의 연구 방향에서 사용자 감성 및 유희성을 포함하는 연구로 그 분야를 넓혀가고 있다. 즐거움, 유희, 재미의 개념들은 연구주제로 다루기에는 비이성적이고 모호하며 주관적이나, 상호작용 연구에서 중심적으로 연구되고 있는 사용성과 사용용이성 측면으로는 연구될 수 없는 특성을 지니고 있다. 상호작용의 여러 가지 특성 중 유희성은 사용자 경험에 있어 중요한 특성이며 상호작용에서 유희성을 구성하는 요소를 파악하고 요인 구성을 통한 유희적 상호작용의 모델을 개발하는 연구가 요구된다. 본 논문에서는 디지털 미디어의 상호작용에서 유희성을 구성하는 요인 분석과 모델 개발을 위한 기본 단계로 제품디자인, HCI, 게임 분야에서 진행된 유희성 관련 연구를 살펴보고 분석을 진행하였다. 이를 통해 디지털미디어는 기존 미디어에 비해 놀이적 성격이 두드러지며 디지털미디어의 사용자가 제품을 사용하면서 얻는 경험은 기능 수행을 바탕으로 이루어지는 상호작용에서 발생하는 특성을 갖고 있음을 알게 되었다. 따라서 디지털미디어의 유희적 상호작용은 기능을 수행하는 과정에서 사용자에게 경험을 풍부하게 만들어 줄 수 있는 구성 방식으로 접근되어야 하며 이러한 방향의 연구가 필요하다고 판단된다. 즉, 사용자가 의도하는 과업을 제품이 적절히 수행하고 있다는 것을 사용자에게 전달함과 동시에 제품을 사용하는 과정에서 감성적 측면을 만족시킬 수 있는 상호작용에 대한 모델 개발이 요구된다. The interaction of digital media is expanding its field from functionality to the users" emotion and amusements. Concepts such as fun, amusement and enjoyment are irrational, fuzzy and subjective for research topics but have the characteristic of being impossible to be studied with ease-of-use and usability. Among the various characteristics of interaction, pleasure is an important characteristic for the user"s experience. In this thesis, researches in product design, HCI and game fields were analyzed, as the basic step for a model development of pleasurable interaction of digital media. Through this, it obtained the results that the digital media has a play personality compared to the existing media and that the user"s experience using the product is created from the interaction based on the functional performance. Therefore the pleasurable interaction of the digital media should be constructed in a way to enrich the user"s experience during the performance of the functions. It is necessary to develop a model that can deliver the message that the product is carrying out the intended task adequately to the uses and at the same time satisfy the emotions.

유연수(Yu Yeon Su) 한국디지털디자인학회 2007 디지털디자인학연구 Vol.7 No.4

문자를 중심으로 이루어지던 컴퓨터 매개 커뮤니케이션(CMC)은 다양한 형태의 시각적 요소의 등장으로 온라인에서 이루어지는 시각적 커뮤니케이션이 오프라인에까지 영향을 미치는 현상을 보여주고 있다. 인터넷의 등장으로 발생한 온라인의 시각적 요소들은 사용자들의 공통된 이해를 통해 일상 생활에서 사용되고 있다. 특히 인스턴트 메신저에서 사용되고 있는 이모티콘의 경우 이미지와 동적인 요소를 첨가하여 다양한 형태로 개발되어 사용되고 있다. 이에 본 연구에서는 커뮤니케이션 과정에서 나타나는 시각화 과정 및 온·오프라인 간에 교류되는 시각화를 살펴보고자 한다. 이를 위해 오프라인과 온라인에서 이루어지고 있는 시각화 예들을 살펴보고 온·오프라인 간에 교류되는 시각화 과정의 연관성을 찾아보았다. 다음으로 시각적 커뮤니케이션의 요인을 알아보고 이모티콘의 활용 방식을 살펴보기 위해 인스턴트 메신저 사용자들을 대상으로 온라인 설문을 실시하였다. 마지막으로 온·오프라인에서 형성된 시각화 방식이 교류되는 현상을 살펴보고 온라인에서 보이는 시각화 현상의 의미와 발전 가능성을 살펴보았다. As Computer Media Communication (CMC) which used to be text-based has adopted various visual elements online visual communication is affecting offline communication. Online visual elements are used in daily life based on users' common understanding. Especially as for emoticon which is used for instant messengers various formations are being developed in combination with image and animation factors. Thus this study examines the visualization process in communication and the visualization between online and offline media. For this the visualization examples in online and offline will be examined and the connection of the visualization procedures of online and offline methods. Then comes the investigation on the visual communication factors and the internet-based survey among instant messenger users in order to find out the utilizing methods of emoticon. Lastly examined are how the visualization methods connecting online and offline media work as well as the possibilities of development of the online visualization phenomenon.

Tumor cell biological factors, such as urokinase plasminogen activator(uPA) and its inhibitor plasminogen activator inhibitor-1(PAI-1) play a role in tumor invasion, metastasis, and proliferation. These factors in patients with primary oral squamous cell carcinoma(Oral SCC) will be evaluated and correlated with clinicopathologic variables. However, relatively rarely has been known in oral squamous cell carcinoma in vivo and in vitro study. The purpose of this study were to investigate the protein expression of uPA and PAI-1 in oral SCC cell lines cell line compared to NHOK and to study migration and adhesion assay. All the cell lines were cultured under KBM bullet kit at 37℃ in a 5% CO2 incubator. We studied a possible association between cytosolic uPA and PA-1 concentrations in oral SCC cell line compared to NHOK using an enzyme-linked immunoassay(ELISA). Cell adhesion and migration assay were done in all the cell lines. In migration assay oral SCC cell lines were about 70 folds higher than NHOK. In adhesion assay oral SCC cell line were about 7-12 folds higher than NHOK. uPA cytosolic concentrations was about 15-19 folds and PAI-1 was 3 to 4.5 folds than that of NHOK. Both uPA and PAI-1 concentrations were correlated with migration and adhesion assay. High cytosolic concentrations of uPA and PAI-1 were correlated with migration and adhesion assay. It suggested that these markers might be specific for oral SCC cell line and these results would be contributed to treatment and prognosis of human oral squamous cell carcinoma.

Sialadenosis is a unique form of non-inflammatory, non-neoplastic bilateral salivary gland disorder characterized by recurrent painless swelling which usually occurs in parotid glands. Alcoholism is one of the main causes of sialadenosis along with diabetes, bulimia, and other idiopathic causes. The prognosis is verified according to the degree of liver function. We present a case of a 46 year-old man who had alcoholic fatty liver disease diagnosed as alcoholic sialadenosis based on clinical points of recurrent bilateral parotid swelling after heavy alcohol drinking, computed tomography, and fine-needle aspiration biopsy. After stopping alcohol drinking and treated with conservative treatment, he got improved without specific sequela. (Korean J Gastroenterol 2009;54:50-54)

This study presents young boys and girls who preparing the role to be adults get a various changed character on social, psychological, physical sides and an experience of transitional developing period. In this time, the training of young boys and girls affects on forming their personalities and attitudes. We can classify according to used Training Center 533 divided named Living Training Facility, Natural Training Facility, Youth Hotel in 16 cities·countries in the whole nation. I researched general used facilities which present two results. one is a posited instructer and the other is an available training program. These show three kind of results as follows: First, on the numbers of housing a day Natural Training Facility which has some more higher capacities than Living Training Facility showed on training facility 183%, the numbers of lodging 227 % the numbers of camping 27 times. Public Institute secures two times of Living Training Facility. In this case there are two reasons, one Local Self Governing Body settled 73.4% of Public Training Facility, the other Local Self Governing Body operated 112 facilities of 114 Trust facilities. Using average a day 145 persons, annual 14,732,015 persons, Using each facility has 41, 421 persons in annual average. Second, on each kind of facility a posited instructer of young boys and girls shows lacked 101% of 379 inspected facilities and non posited 156(41%) facilities. public facility is 72% the other side private facility secured 131%. A posited status of instructer at present secured 100% above in ten cities·countries and 6 cities·counties 100% below. 171 facilities lacked and non posited of 379 facilities. Third, Natural Training Facility and Living Training Facility which are very similar have been operating available training program 50% as cultural activities, the former has more 288% on physical activities, 654% on camping activities, 520 on natural research activities shown many programs operated than the latter.

The spectral changes of polychromatic spatially coherent gaussian beams focused by an aperture lens in the focal plane is studied based on the propagation law of the cross-spectral density function. The numerical simulation results are presented and the experimental observation results of a spectral changes that take place in the Airy rings formed by diffraction of partially coherent polychromatic light in the focal plane of an aperture lens are presented. The experimental observations show vary similar results with numerical simulation and it is shown that at the critical position U<SUB>c</SUB>, the spectrum is split two lines, while at a position a little smaller than U<SUB>c</SUB>, the spectrum is red-shifted, and at a position a little larger than U<SUB>c</SUB>, the spectrum is blue-shifted. In addition, rapid spectral changes of spatially coherent light may be exploited for information encoding and information transmission in free space optical communications.
