Factorial designs with two-level factors represent the smallest factorial experiments. The system of notation and confounding and fractional factorial schemes developed for the $2^N$system are found in standard textbooks of experimental designs. Just as in the $2^N$ system, the general confounding and fractional factorial schemes are possible in $3^N,5^N$, .... , and $\rho^N$ where $\rho$ is a prime number. Hence, we have the $\rho^N$ system. In this article, the author proposes a new algorithm for constructing fractional factorial plans in the $\rho^N$ system.

A roentgenocephalometric approach was performed by the author for the purpose of investigating cranio-facial complex of normal Korean female adults. Thirty roentgenocephalograms of the Korean female adults with normal occlusion among one thousand and two hundreds of samples were selected for this research. Standards of each items of angular and linear measurements on lateral view and linear measurements in P-A view were figured out. In some items, co-relations were traced to search reciprocal relationships. Some of the measurements were compared with other reports.

During the sintering of powder materials, many these are microstructural phenomena are caused by atomic diffusion. (1) neck formation and compact densification, (2) grain growth, i.e., growth of matrix grains and dispersed grains, (3) alloying or generation of compound, (4) generations of peculiar and hard layers near sintered compact surface, etc. The studies of the present author and co-workers on these phenomena which were carried out during 40 years are briefly introduced.

Author has determined the dissociation velocity constant of carboxyhemoglobin in cattle blood solution by addition of ascorbic acid at $36-38{\deg}.$ It was found that these kinetic data are concordant with Roughton's equation d[COHb]/dt = $m^{'}[CO][O_{2}Hb]/[O_{2}$ - m[COHb] and that the dissociation velocity constant of carboxyhemoglobin was accelerated by the presence of ascorbic acid from 0.119 to 0.135.

The author studied the hemolytic action of chlorpromazine on rabbit erythrocytes and obtained the following results: 1. Chlorpromazine caused hemolysis in vitro. The hemolytic action of chlorpromazine was milder than that of saponin(Colleman and Bell Co ) 2. Cholesterol had no marked effect on chlorpromazine hemolysis. 3. Dextrose, albumin and blood plasma protected erythrocytes against chlorpromazine hemolysis. 4. The mechanism of chlorpromazine hemolysis seemed to be different from that of saponin hemolysis. 5. Chlorpromazine increased tile osmotic fragility of rabbit erythrocytes. 6. The intravenous injection of chlorpromazine caused hemolysis in vivo.

최근 학제간 연구에 대한 관심이 커지면서 자연스럽게 연구자들 간의 협력관계, 특히 학술적 협력관계에 대한 관심 역시 증가하고 있다. 이에 따라 공저 네트워크 자체의 속성에 대한 연구 뿐만 아니라 공저 분석 기법을 통해 특정 학문 분야의 지적 구조를 해석하려는 연구들이 꾸준히 진행되고 있다. 본 연구는 공저 네트워크 분석을 통해 국외 학제적 저널의 공저 현황과 소속기관 유형을 살펴보고 매개 중심성과 연결정도 중심성을 통해 학술지별 주요 소속기관과 저자들의 위치, 그리고 그들간의 협력 관계를 살펴보고자 하였다.

Objectives: The purpose of this article was to assess epidemiological characteristics and recommendations for strengthening national response and preparedness after MERS-CoV outbreak in Korea, 2015. Methods: The author reviewed epidemiological reports and policy recommendations on MERS-CoV outbreak in Korea, 2015. Results: There was no evidence that genetical difference between the MERS viruses in the Republic of Korea and recent viruses in the Middle East. From the index case to last laboratory-confirmed case, there were 186 laboratory-confirmed cases that included 36 deaths(19.4%), all of whom appear epidemiologically linked to the index cases or subsequent secondary, tertiary, and quaternary cases. This outbreak spread to hospitals through nosocomial transmission. At least, three large clusters were investigated. However, there was at least one case of community transmission of MERS-CoV. Several factors had contributed to the MERS outbreak in Korea, 2015 that including epidemiological characteristics, and infrastructure of national healthcare system for preventing and controlling emerging infectious diseases. Conclusions: It is very important that to share experiences and identify underlying causes of this outbreak for prevention and control of emerging infectious disease in the future; including epidemiology, clinical features, and public health response and preparedness.
