This paper deals with the questions: Are media user's activities labour? Or rent? These questions have provoked a debate in the critical media studies and Marx's theory. But it is not a matter of choosing either labour or rent. Even if user's activities could contribute to valorization, it needs some mediating process. Media Platforms-Google, Facebook, etc.-play a key role, and have to employ other forms of labour. Labour in media platform produces some capital commodities. In view of media platform, Smythe's audience commodity can be considered as capital commodity. Assertion in this paper expected to provoke new debate on media platforms and its labourer.

Taussig-Bing anomaly is infrequently associated with interrupted aortic arch and size discrepancy of great arteries makes it difficult to undergo arch reconstruction and arterial switch operation. A 20-day old male infant was admitted with the diagnosis of Taussig-Bing anomaly with type B Interrupted aortic arch. Multi-organ failure, due to the diminution of ductal flow, was stabilized after 3 weeks of prostaglandin El and controlled ventilatory support. The surgical correction consisted of VSD closure, arterial swtich and extended aortic arch reconstruction. The marked disparity between the hypoplastic ascending aorta and the dilated main pulmonary artery was overcome by constructing distal neoaorta using both native ascending and descending aortic tissue. The patient was extubated on postoperative 2nd day Postoperative catheterization showed no left ventricular outflow obstruction, no intracardiac shunt, and no incompetence of neoaortic valve.

Various Eulerian-Lagrangian numerical models for the one-dimensional longitudinal dispersion equation are studied comparatively. In the model studied, the transport equation is decoupled into two component parts by the operator-splitting approach ; one part governing adveciton and the other dispersion. The advection equation has been solved using the method of characteristics following fluid particles along the characteristic line and the results are interpolated onto an Eulerian grid on which the dispersion equation is solved by Crank-Nicholson type finite difference method. In solving the advection equation, various interpolation schemes are tested. Among those, Hermite interpolation polynomials are superior to Lagrange interpolation polynomials in reducing dissipation and dispersion errors in the simulation.

The selective cleavage of phenylsilane by triflic acid gives silyltriflates. The removal of phenyl groups in $Ph_3SiH$ and carbosilane polymer $(Ph_2SiCH_2CH_2CH_2)n$ with one to two equiv of triflic acid leads to formation of mono- and disubstituted silyltriflate ester bonds. Reaction with allylmagnesium bromide produces corresponding derivatives with good yields. An organosilane dendrimer with allylated carbosilane polymer has been synthesized up to G3 using repetitive allylation hydrosilylation cycles.

This study investigated the relation between the liberal arts education service and students' satisfaction. The results of the study show that students are satisfied with all of five service quality factors, students' intention of studying, full time instructors' teaching and high GPA in taking liberal arts classes. However, educational factors such as the quantity of home work, frequency of test and the size of class, which can influence the quality and contents of classes, do not impact the students' satisfaction of liberal arts education. The college students of Korea may tend to be more satisfied with the liberal arts classes which they feel easier to study and to get better grades.

Reynolds Averaged Navier-Stokes equations are solved numerically for the computation of turbulent flow around a Wigley double model. A second order finite difference method is applied for the spatial discretization on the nonstaggered grid system and 4-stage Runge-Kutta scheme for the numerical integration in time. In order to increase the time step, residual averaging scheme of Jameson is adopted. Pressure field is obtained by solving the pressure-Poisson equation with the appropriate Neumann boundary condition. For the turbulence closure, 0-equation turbulence model of Baldwin-Lomax is used. Numerical computation is carried out for the Reynolds number of 4.5 million. Comparisons of the computed results with the available experimental data show good agreements for the velocity and pressure distributions.

This study is the first research for the lawyers' office service quality in Korea. Several T-tests' results show that the performance of lawyers of ace service was perceived much lower than the expectation of customers. A causal analysis was conducted to identify which service qualify factors influence customers' satisfaction of the lawyer's office in Korea. The results of the analysis show that tangible and empathy service qualify factors are the most important factors for the lawyers' customers' satisfaction. Thus, lawyers' office should invest some money in selecting location and building including interiors to increase customers' satisfaction in Korea. And then. lawyers should improve the empathy quality factor which make their customers feel their law office comfortable and helpful to them.

Purpose: This study was done to evaluate the incidence, type of injury, medical consequences, mortality, and prognostic factors associated with stab wounds in patients who visited Kangnam Sacred Heart Hospital, Hallym University, Seoul, Korea. Methods: A retrospective analysis of the clinical data of 40 patients with abdominal stab wounds who visited Kangnam Sacred Heart Hospital, Hallym University, Seoul, Korea from January 1, 2000 to December 31, 2004. Results: 1) The most prevalent age group was patients in their the twenties to fourties (77.5% of all patients), and average age of the patients was 39.3 years. The male-to-female ratio was 2.07:1. 2) The external site of stab wounds was most commonly the periumbilcal area of the abdomen (14 cases, 33.3%). 3) The most commonly injured organs were the liver and the stomach (10 cases each, 16.9%). 4) Operations were performed on all 40 patients, with 9 (22.5%) negative operation findings. 5) Death occurred in 5 cases (12.5%). 6) The trauma indices of the death group were TRISS 51.9%, RTS 3.6 points, and APACHE II 23.0 points. 7) The average transfusion amount of the death group was 13.8 pints Conclusion: These data suggest that the transfusion amount and the trauma index of abdominal stab injuries may be statistically significant factors for predicting mortality.

중원지역 지열수의 CO2 가스의 용축과 수반된 탄산염 침전물의 광물학적 특성을 밝히기 위하여 탄산염 침전물에 대해 광물학적 및 지구화학적 분석방법을 적용하여 보았다. 이들은 매년 수 mm의 두께로 저수조내에 침전되며 미세한 층상으로 결정화되어 있고, 검은 갈색의 얇은 층들이 반복적으로 존재하고 있다. 침전물은 비교적 순수한 방해석으로 되어 있으며 1M HCl로 처리하여 잔류물을 XRD 분석한 결과는 카올린 광물 및 일라이트질 광물이 확인되었다. 전자현미분석에 의하면 검은 갈색층은 주로 방해석과 Fe나 Mn 산화광물의 집합체이며 소량의 점토광물도 함께 섞여 있는 것으로 추정된다. Fe의 경우에는 주로 방해석내 Ca자리를 치환하여 존재하며 일부 산화광물로 함께 침전된 것으로 보인다. 반면에 Mn의 경우는 일부는 Fe처럼 방해석결정구조 내에서 Ca를 치환하면서 존재하기도 하지만 주로 산화물의 형태로 존재하는 것으로 보인다. 후방산란전자상(BSEI) 관찰에 의하면 Fe와 Mn 모두 매우 미세한 입자의 산화광물들로 밀집해 있는 부분이 관찰되기도 한다. 중원지역 탄산수로부터 방해석이 침전되는 과정은 CO2 가스가 방출되면서 pH가 증가하면서 방해석 및 Fe, Mn 산화물이 과포화상태가 되어 침전되는 것으로서 해석할 수 있다. 또한 지하 심부를 순환하면서 활발한 물-암석반응의 결과로 Si나 Al 및 기타 이온들의 함량이 상대적으로 높았던 탄산수가 pH가 높아지면서 카올린 광물이나 일라이트질 광물, 석영등의 규산염 광물들이 함께 침전하였을 것이다. 그러나 방해석의 침전과정이 이루어지는 과정 동안에, 온천공으로부터 채수되는 탄산수의 양이 수요에 따라 매우 불규칙해서 탄산수의 수요가 많은 경우 탄산수가 지속적으로 과잉 채수되면 주변 천층지하수가 탄산수에 혼합되어 Fe, Mn 등의 농도를 상대적으로 낮추게 되어 산화물형태로 침전되기가 어려워져서 거의 순수한 방해석만이 침전하게 된다. 결과적으로 거의 순수한 방해석 층에 검붉은 층이 불규칙하게 반복되고 있는 중원지역 탄산염침전물은 침전작용이 일어나는 대부분의 기간 동안 지속적으로 주변 전층지하수의 유입이 일어났음을 지시하고 있다. 또한 Fe, Mn 등의 함량이 높은 탄산수로부터의 침전은 매우 짧은 기간동안 단속적으로 일어났음을 지시한다.
