김병욱 한국화학공학회 1967 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.5 No.2

Adsorptivities, solid surface acidity, specific surface area, bulk density, electron microscopic observation etc. have been measured on the traces and investigated which are accompanied by the change of principal factors in manufacturing active carbon for liquid phase, activated with ZnCl₂. As a result, concerning the important operation factors of activation time, activation temperature, amount of ZnCl₂, amount of HCl, raw material size, active carbon size etc., the optimum conditions causing a good activation state were found out, and moreover, mechanisms of ZnCl₂ and HCl adding effect, activation, and overactivation are clarified. The correlation of each factor of solid surface acidity, specific surface area, pore distribution etc. to adsorptivity, and the significance of measuring bulk density also are brought to light.

The Sinheung porcelain factory produced white porcelain and black porcelain at the same time in the late Joseon Dynasty, and this tradition has been maintained to this day. Such a pottery tradition is difficult to find, not just in the Gangwon-do Province but also nationwide. The factory’s record of ceramic production was compiled in 1916 in Samchukunji, Sinheung-ri also produced a lot of porcelain. Through this, it can be seen that fraudulent production was already prevalent in the Sinheung porcelain factory before 1916. The characteristics of the Sinheung factory’s ceramic production can be summarized as follows: first, it produced white porcelain and black porcelain at the same time. This is usually difficult due to the different materials involved, such as soil and glaze. Generally, one kiln produces a field of pottery. The Sinheung factory overcame this and produced ceramics in two fields. Second, ceramics were produced by classifying grades. The best-made bowl was called “Won-gi,” the commonly used bowl was “Sang-gi,” and the bowl made of lower-grade ceramics was “Ha-gi.” All three classes of products were completed with pottery after being baked in a kiln. When the kiln cooled, the objects were taken out and the defective ones were eliminated. These may have included bowls whose glaze had not melted well or broken due to the excessive temperature in the kiln. This selection process was called “Pagi” and the rejects were destroyed in a dedicated place called “Pagi-Jang.” This is considered to be a characteristic of the Sinheung porcelain factory, which is difficult to find in other regions. Third, when making black porcelain, locally produced red ochre was used as the raw material for the glaze. This production process has been followed from the Goryeo and Joseon periods until the present moment; however, its importance has not been sufficiently recognized and studied by researchers. Therefore, this study summarizes the context of black porcelain production at the Sinheung porcelain factory by revealing the conditions under which red ochre, a raw material used for manufacturing the glaze, which has not been known. In other words, the factory was able to produce the two types of porcelain based on the regional specificity and environment, which facilitated the supply and demand of raw materials necessary for ceramic production such as clay and red ochre. The continuation of this porcelain production tradition has been made possible by family inheritance and commitment to its original quality standards. The Sinheung porcelain factory was started by Kwak Bong-jae (unknown date of birth and death) in the late Joseon Dynasty and was bequeathed to his son Kwak In-ok (1877-1964), who then passed it on to his eldest and second sons, Kwak Yong-up (1911-1992) and Kwak Yong-woon (1914-2008). At the third generation, however, the tradition of pottery production suffered as plastic and nickel-silver bowls became popular. As a result, Kwak Yong-woon was not succeeded by his son in the factory’s administration, which was transferred to one of his collaborators, Shin Won-soo, so that the tradition could continue. Shin Won-soo had the necessary abilities to produce ceramics and committed to preserve the original production techniques, tools, and raw material collection procedures at the Sinheung porcelain factory. The ceramic production tradition of the Sinheung Porcelain factory was inherited by direct descendants from the 1st to 3rd generations, and was passed on to other people with the ability to produce ceramics from the 3rd to 4th generations.

나노 소자의 SPICE 모델링 방법 고찰

김병욱 영산대학교 2004 영산논총 Vol.14 No.-

In this paper, the problems arisen from the nano-scale dimension of the device included in system modeling and simulation technologies are seriously studied, and a nano-scale compact modeling methodology is proposed with an emphasis of reusing the SPICE model and conventional electronics design automation technologies. Compact model carries physical parameters out of the device model and to the SPICE model for the purpose of maintaining quantum-size effects at each modeling abstraction level while the SPICE model connects system design to circuit design by means of conventional EDA design flow to free system design methodologies from the influence of the quantum-size effects.

광전소자를 위한 하이브리드 모델

김병욱 영산대학교 2002 영산논총 Vol.10 No.-

Considerable difficulty in the optoelectronic system design arises from not only the complexity of the system but also device physics involved. Both electronic and optical operating mechanisms that are based on totally different device physics simultaneously affect the optoelectronic devices. In this paper, the principles of both optical and eletronic properties are seriously studied and a hybrid model for optoelectronic devices as well as SPICE simulation is proposed.

디지털 영상감상에 나타난 사용자 참여적 현상에 관한 연구 : 웹환경을 중심으로 Focused on the Web environment

김병욱 朝鮮大學校 社會科學硏究所 2002 社會科學硏究 Vol.23 No.1

디지털 영상의 활용이 급격히 증가하고 있는 가운데 기존의 디지털 영상표형은 표현의 기법중심으로 발전해 왔다고 할 수 있다. 그러나 디지털 영상이 감상 중심에서 웹을 기반으로 하는 표현매체를 통해 "영상의 사용"이라는 관점으로 변해가면서 그 활용이 다채로와 지고 있다. 영상에 있어서의 참여적 영상의 구현이 필요하게 되었고, 적극적인 사용자의 참여에 의한 매시지 전달의 효율성 극대화와 비선형구조의 스토리전개, 새로운 디지털 영상 미학의 창조 등 다양한 파급효과를 유발할 수 있는 가능성이 나타나고 있다. 이러한 상황에서 영상의 사용에서 발생할 수 있는 사용자와의 상호작용을 규명하고, 영상표현 자체에서의 사용자 참여 가능성을 살펴본다.

도심지 하수관거의 I/I 및 CSOs 특성

김병욱,최승철,원철희,임재명 강원대학교 부설 석재복합신소재 제품연구센터 2003 석재연 논문집 Vol.8 No.-

본 연구에서는 도심지 하수관거의 특성을 파악하기 위하여 원주시를 대상으로 수질 및 유량 조사를 통하여 기존 하수관거의 침입수/유입수(I/I) 분석 및 하수관거 정비사업시 우선순위 결정을 위한 자료제공과 강우시 CSOs의 발생특성을 분석, 결과를 고찰하였다. 그 결과 원주시의 조사지점별 평균 BOD는 원주하수종말 처리장 설계기준과 비교하여볼 때 26.O~60.7%로 매우 낮게 배출되는 것으로 조사되었으며, 평가기법에 의한 원주시 도심지역의 I/I율은 평균하수량의 35.7~74.6%로 매우 높은 것으로 조사되었다. 또한, 강우시 발생하는 CSOs는 배수유역의 크기와 강우량, 강우강도, 차집용량에 따라 큰 유량차이를 보였으며, CSOs의 수질분석결과 강우초반부 초기세척(First-flush)현상으로 수질이 급격히 상승하였다가 감소하는 것으로 나타났으며, CSOs의 BOD부하를 살펴보면 일평균 BOD부하의 18.7~38.5%이상으로 인근수역으로 미처리되어 배출되는 것으로 조사되었다. 이와같이 하수관거의 I/I율과 CSOs의 발생특성은 조사지점의 특성에 따라 큰 차이가 있으므로 관거정비사업시 이에 대한 충분한 조사 및 분석이 이루어져야 할 것이다. Infiltration/Inflow(I/I) is the major deterrent to the successful performance of the sewer and the treatment systems. An excessive I/I in a sanitary sewer system can hydraulically overload the sewer lines and the wastewater treatment plants and combined sewer overflows(CSOs) are untreated wastewater during storm events. The characteristics of the CSOs are extremely variable, depending upon local physical conditions such as topography, soil conditions, degree of development and imperviousness of surface. As a result of the flow rate and water quality monitoring, biochemical oxygen demand(BOD) concentration was significantly low as 26.0-60.7% of 173mg/L which is a design standard of wastewater treatment plant. I/I rate of sewer in the center of Wonju city evaluated by assessment method was very high as 35.7-74.6% of total flow. Furthermore, 18.7-385% of BOD load of CSOs during wet weather was discharged into watershed with being untreated. As stated above, I/I running into sewer system should be considered before everything when sewer system is improved and CSOs generated during wet weather should be necessarily deliberated for design of water treatment plant and improvement of sewer system.

예술과 과학은 인간의 삶을 풍요롭게 해주는 인간의 훌륭한 자산이다. 다만 문제는 인간의 풍요로운 삶을 약속한 이 자산이 그 구실을 제대로 못하고 있는 데에 현대의 고민이 있다. 결국 과학은 이 지구상에 발을 붙이고 살고 있는 인간에게 보다 훌륭한 삶의 수단이다. 그러나 그것 자체는 결코 목적이 될 수 없다. 인간에게 희망의 미래를 제공해 줄 것 같은 과학이 안고 있는 여러 문제점은 많은 시대적 이슈를 낳고 있다.
