鉛直接合의 剛性이 프리케스트 剪斷壁의 構造的擧動에 미치는 影響
朴經浩 江原大學校 産業技術硏究所 1983 産業技術硏究 Vol.3 No.-
Recent developments in multi-storey buildings for residential purpose have led to the extensive use of shear walls for the basic structural system. When the coupled shear wall system is used, joined together with cast-in-place concrete or mortar (or grout), the function of the continuous joints is a crucial factor in determining the safety of L.P. Precast concrete shear wall structures, because the function of the continuous joints(Vertical wall to wall joints) is to transfer froces from one element(shear wall panel) to another, and if sufficient strength and ductility is not developed in the continuous joints, the available strength in the adjoining elements may not be fully utilized. In this paper, the influence of the stiffness of vertical joints(wet vertical keyed shear joints) on the behaviour of precast shear walls is theoretically investigated. To define how the stiffness of the vertical joints affect the load carrying capacity of L.P.Precast concrete shear wall structure, the L.P.Precast concrete shear wall structure is analyzed, with the stiffness of the vertical joints varying from K=0.07kg/㎣(50MN/m/m) to K=1.43kg/㎣(1000MN/m/m), by using the continuous connection method. The results of the analysis shows that at the low values of the vertical stiffness, i.e. from K=0.07kg/㎣(50MN/m/m) to K=0.57kg/㎣(400MN/m/m), the resisting bending moment and shearing force of precast shear walls, the resisting shearing force of vertical joints and connecting beams are significantly affected. The detailed results of analysis are represented in the following figures and Tables.

장용성 란소프라졸 캅셀의 제조 및 생물학적 동등성 시험
박경호,남궁형욱,신완균 한국병원약사회 1997 병원약사회지 Vol.14 No.3
Iansoprazole, (H+/K+)-ATPase (proton pump) inhibitor is being widely used to gastro-intestinal peptic ulcer patients. Koryo Pharmaceutical Company tried to develope lansoprazole capsule bioeqivalent to already being marketed lansoprazole capsule, reference product, which is producted by Hanil Pharmaceutical Company. Through in vitro dissolution tests of preformulated test capsules (Test capsule A, B, C and D) compared with reference, one capsule (Test capsule D) compared with reference, one capsule (Test capsule D) was selected which had a very similar dissolution profile as reference. And bioequivalence test in human volunteers was conducted to obtain marketing approvement of test capsule D. Dissolution tests of preformulated products were conducted in dissolution solution I (acid solution, pH 1.2) by dissolution method Ⅱ(paddle method) (KP Ⅵ) for 60 minutes, and then followed in dissolution solution Ⅱ(phosphate buffer, pH 6.8) by dissolution method Ⅰ (basket method) (KP Ⅵ) for 60 minutes. The dissolution solutions was maintained at 37±0.5℃, and basket and paddle were rotated at 150± 5 rpm, respectively. Also, in bioequivalence test, 14 healthy male volunteers were administered one capsule of test capsule(30 ㎎ lansoprazole/cap, Koryo Pharm. Co.) or reference, and randomized two-period, cross-over study was applied. Bioequivalence was statistically analyzed between two products using pharmacokinetic parameters (AUC, C_(max) and T_(max)). The results showed that the differences in AUC, C_(max) and T_(max) between two products were 8.75%, 9.32% and 29.79%, respectively. Detectable (△) of AUC, C_(max) ands T_(max) were 15.79%, 18.18% and 45.17%, at α=0.1 and power (1-β)=0.8, respectively, and also confidence intervals were -1.91% ≤△≤ 19.41%, -2.96% ≤△≤21.59% and -0.70%≤△≤60.28%, respectively. Among pharmacokinetic parameters, AUC met the criteria of KFDA for bioequivalence, while T_(max) and C_(max) didn't meet exactly the criteria of KFDA. But lansoprazole is medicated for long term, and C_(max) did't meet exactly the criteria of KFDA. But lansoprazole is medicated for long term, and absorption amount is more important rather than absorption rate. So considering on clinical aspects of lansoprzole, it was concluded that test capsule, Lansid^(R), is bioequivalent to reference, Lanston^(R) capsule by KFDA.

약물역학 특수연구회(Pharmacoepidemiology SIG)의 운영현황과 발전방향
박경호 한국병원약사회 1999 병원약사회지 Vol.16 No.3
약물역학은 인구집단에서 약물의 사용과 효과를 연구하기 위하여 역학적인 지식과 연구방법론을 적용해서 정해진 시간과 공간 및 인구집단에서 치료 목적으로 사용된 약물을 기술하고, 설명하고, 통제하고, 그 효과를 예측하는 학문으로 역학(epidemiology)과 임상약리학(clinical pharmacology)이 접목된 분야라고 할 수 있는데, pharmacoepidemiology, Drug epidemiology, Postmarketing surveillance(PMS), Phase 4 clicical trial 등의 여러가지 용어로 쓰일 수 있다.

The communication systems and characteristics of transmit take a serious view of ubiquitores society. The high rate networks have to construct for data of voice, graphics and moving-video with the multimedia to transmit. The wireless Internet is progressing by the service in Korea. The rate of data are relation that there are the bandwidth of line and channels, the speed per second and communication-systems. This paper study for the error performance of 2, 4 level FSK to transmit amount of data from the ASK, AFK, FSK, PSK and QAM in the communication systems.

朴敬鎬 木浦海洋大學校 1993 論文集 Vol.1 No.1
Nowadays, it comes from the Society of industry to the information society. It means that the intelligent society by information is important the immaterial additional value of knowledge, intelligence information more than money or property. The information society have been to America in 1956 and Japan in 1971 and it will get accomplighed us at 21th century. The information has become to very important not only the war operation but also the field of economic. This society is circulating the information to get economic value and the basis of information society consit of computer to process the mass information and new communication system. Thery are many information services news, atmosphere, culture, sight, home, health, securities, economy, industry, technology, society, civil-administration, home shopping, E-mail and video conference and so on. In a high state of information society, so the information comes out quantitatively, for make the information valued, this paper study for the relation between data communication and transitional society.
