Histalog 자극(刺戟) 위액(胃液)에 있어서 분비(分泌)된 유리(遊離)염산의 총량(總量)과 최고농도치(最高濃度値)에 관(關)한 연구(硏究)
김문수,고광도 대한소화기학회 1970 대한소화기학회지 Vol.2 No.2
The gastric juice analysis of 142 cases (67 normal cases, 46 peptic ulcer cases, and 29 gastric carcinoma cases) after the injection of Histalog (0.5mg/kg) was compared with the difference of percentages in each group of acidity, which was classified by normal mean value of total amount (12.43±7.54 mEq/60min) and peak value of gastric fractional analysis (57.33±25.79mEq/15min) of free HCl, ie. Hyperacidity, normoacidity, hypoacidity, anacidity. The result obtained was as follows: 1. In 67 normal cases: a) As regards total amount of free HCl, 46 cases (68. 5%) had normoacidity, 7 cases(10, 8 %) had hyperacidity, 10 cases (14.9%) had hypoacidity, there was not anacidity group. b) As regards peak value of free HCl, 43 cases (64.2%) had normoacidity, 10 cases (14.9%) had hyperacidity, 10 cases (14.9%) had hypoacidity, there was not anacidity group. 2. In 22 gastric ulcer cases: a) As regards total amount of free HCl, 11 cases (50%) had hyperacidity, 8 cases (36.4%) had normoacidity, 3 cases (13.6%) had hypoacidity, there was not anacidity group. b) As regards peak value of free HCl, 4 cases (18.2%) had hyperacidity, 16 cases (72.7%) had normoacidity, 2 cases (9.1%) had hypoacidity, there was not anacidity group. 3. In 24 duodenal ulcer cases: a) As regards total amount of free HCl, 18 cases (75%) had hyperacidity, 3 cases (12.5%) had hypoacidity, 3 cases (12.5%) had normoacidity, there was not anacidity group. b) As regards peak value of free HCl, 15 cases (62.5%) had hyperacidity, 7 cases (29.2%) had normoacidity, 2 cases (8.3%) had hypoacidity, the was not anacidity group. 4. In 29 cases of the gastric car cinoma: a) As regards total amount of free HCl, had normoacidity, 8cases (27.6%) had 5 cases (17.2%) had hyperacidity, 2 cases (6.9%) hypoacidity, 14 cases(48.3%) had anacidity group. b) As regards peak value of free HCl, 4 cases (13.8%) had hyperacidity, 6 cases (20.7%) had normoacidity, 5 cases (17.2%) had hypoacidity, 14 cases (48.3%) had anacidity group. 5. The difference of percentages in gastric acidity according to each mean value of total amount and peak value of free HCl was detected as shown above.

This paper analyzes the characteristics of embodied technological knowledge flow - structure of Korean manufacturing in dynamic perspective, and the relations among knowledge (R&D), embodied knowledge and the rate of technological progress (TFP growth) considering the flow - structure. In doing that, the concept of the embodied knowledge network is introduced which is defined as a set of industries and their interaction (embodied knowledge flow) or linkage. The analysis of the inter - industrial embodied knowledge flows is based on the input - output technique for the 1983-93 period and is carried out by such methodology as network analysis, indicator analysis and regression analysis. The main findings are as follow. First, the structure of embodied knowledge flow can be distinguished between the knowledge out flow sect or sand the inflow sectors. The outflow sectors seem to form the multi - central structure and the inflow sectors to form the dualistic structure. Second, in the both of outflow and inflow sectors, we can find significant spillover from embodied knowledge respectively. Furthermore, TFP growth in the knowledge inflow sectors is positively related to spillover through the intermediary sectors.
ITU Access Network의 기능적 모형에 근거한 이동망의 가입자 접속 부문 정립에 관한 연구
김문수,Kim, Moon-Soo 한국통신학회 2003 韓國通信學會論文誌 Vol.28 No.1A
Access Network은 대부분의 정보통신망에서 가장 중요한 요소라 할 수 있다. 또한 최종 이용자에서 직접 연결되는 부문으로 가장 많은 투자 재원이 요구되며, 최근에는 광대역의 매우 다양한 접속 기술이 개발 보급되고 있는 상황이다. 가입자의 이동성에 따른, 그리고 무선 전파 자원과 유선 교환 및 전송망을 이용한다는 복합적 특성으로 인하여 기존 유선의 가입자 망과는 다르게 이동망의 Access Network 내지는 가입자 접속부문에 대한 명확한 정의나 상세한 기능 및 범위가 정립되지 못하고 있는 상황이다 이에 본 논문은 ITU-T의 일반적인 Access Network의 기능적 모델을 참조하여 IS 95 A/B 및 cdma2000-1X 이동통신기술 표준의 음성 서비스를 위한 CDMA 기지국 시스템, 기지국 제어 시스템, 이동교환시스템 등의 하위시스템의 특성과 기능을 고찰하여 보다 체계적이고, 기능적 관점에서의 가입자 접속부문에 대한 대안적 정의를 제시한다. Access network is one of the most critical components of telecommunication networks. Essentially it provides the final connection through to the subscriber and at the same it is usually the most expensive component in terms of capital investment and ongoing cost of maintenance and repair In recent, various access technologies with broadband have been developed and also are emerging newly Comparing fixed access networks, the concrete concept as well as the scope of mobile access networks or parts has not been defined yet although it is caused by peculiarities of mobile network with mobility-guarantee technology, use of RF resource, fixed-exchange and transport networks This article examines the characteristics and detailed functions of BTS, BSC, MSC and other components in CDMA mobile network under the IS-95 A/B and cdma 2000-1x standards comparing the ITU's access network functional model From the systematic and functional perspectives, futhermore, an alternative definition for access parts of mobile network is proposed.
