It is obvious that adequate nutrition is essential for growth and development of school children, and many elementary schools in this country have already practiced it. Therefore, it would seem apparent that the school feeding program would have a significant effect on the growth and development of school children. This paper presents a two-year experimental school-feeding program from 1973 to 1974, and attempts to evaluate its effects by before-and-after nutrition surveys conducted in two elementary schools, one experimental and the other as a control. The two schools are both located in the same county (Yongin-Kun, Kyunggi-Do), and the families of their students are presumed to share the same socio-economic level. To assess the effect of school-feeding, we measured height, weight, chest circumference and grasping power. Physical examination was done foresigns of nutritional deficiency. A stool examination for parasites and blood examinations for hemoglobin, hematocrit and serum protein were included. Analyses were done for 150 students selected randomly at the beginning of the program. These students attended the school throughout the program period. Results are as follows: 1. The amount of increase of height, weight, chest cirumference and grasping power were greater in the experimental school than in the control school, but the differences are not statistically significant. 2. Signs of vitamin deficiency decreased in both experimental and control schools during the two-year program period. 3. At the time of the 1974 post-survey, values of Hb. & Hct. revealed no significant differences between the two schools, but serum protein level was a little higher than that of general Korean rural children of the same age. 4. Infestation rate of parasites had increased in both schools during the two-year program period. 5. Each student of the two schools was classified into three major classes, according to the level of economic condition of his or her parents, namely higher, middle and lower. The results of each class of the experimental school was compared with that of the corresponding class of the control school, expecting the relative magnitude of change largest in the lower economic class of the experimental school. However, change was greatest in the middle class, still not being statistically significant. Finally, the authors concluded that the two-year period for such a program is not sufficiently long for its beneficial effects to be demonstrated and measured. As long as the growth and development of children are concerned, planning with a more distant perspective is required, as well as the development of new methods of evaluation.

김명호,이도재,이광민,김운섭,김민기,박범수,양국현,Kim, Myoung-Ho,Lee, Doh-Jae,Lee, Kwang-Min,Kim, Woon-Sub,Kim, Min-Ki,Park, Burm-Su,Yang, Kook-Hyun 한국재료학회 2008 한국재료학회지 Vol.18 No.10

TiAlN films were deposited on WC-5Co substrates with different buffer layers by D.C. magnetron sputtering. The films were evaluated by microstructural observations and measuring of preferred orientation, hardness value, and adhesion force. As a process variable, various buffer layers were used such as TiAlN single layer, TiAlN/TiAl, TiAlN/TiN and TiAlN/CrN. TiAlN coating layer showed columnar structures which grew up at a right angle to the substrates. The thickness of the TiAlN coating layer was about $1.8{\mu}m$, which was formed for 200 minutes at $300^{\circ}$. XRD analysis showed that the preferred orientation of TiAlN layer with TiN buffer layer was (111) and (200), and the specimens of TiAlN/TiAl, TiAlN/CrN, TiAlN single layer have preferred orientation of (111), respectively. TiAlN single layer and TiAlN/TiAl showed good adhesion properties, showing an over 80N adhesion force, while TiAlN/TiN film showed approximately 13N and the TiAlN/CrN was the worst case, in which the layer was destroyed because of high internal residual stress. The value of micro vickers hardness of the TiAlN single layer, TiAlN/TiAl and TiAlN/TiN layers were 2711, 2548 and 2461 Hv, respectively.

비양론성 Rutile에서 결함구조와 전기적 물성

김명호,백운규,Kim, Myeong-Ho,Baek, Un-Gyu 한국재료학회 1996 한국재료학회지 Vol.6 No.12

산소분압과 온도변화에 따라 비양론성 rutile(TiO2-x)의 결함모델을 전기전도 측정법에 의해 연구하였다. 산소분압과 전기전도도의 상관관계에 의하면, rutile에서 주결함은 2가로 하전된 산소빈자리와 4가로 하전된 침입형 티타늄이온이다. 117$0^{\circ}C$이상의 온도에서는 침입형 Tii…이온이 지배적인 결함이었으나, 117$0^{\circ}C$이하의 낮은 산소분압대에서는 2가로 하전된 산소빈자리가 주된 결함이었다. rutile의 전기전도 실험에서 제안된 결함모델은 본 연구팀이 O18추적자 확산실험에 의해 제안하였던 결과치와 일치하였다.

수퍼스칼라 프로세서를 위한 컴파일러에서 조건부 분기의 최적화

김명호,최완,Kim, Myung-Ho,Choi, Wan 한국정보처리학회 1995 정보처리논문지 Vol.2 No.2

본 논문에서는 수퍼스칼라 프로세서를 위한 컴파일러에서 조건부 분기 명령을 제 거하는 최적화 기법을 제시하였다. 분기를 제거하는 단계적 방법으로 먼저 대수적 규 칙을 사용하여 분기를 산술식의 형태로 변형하고, 그 식에 대응하는 명령 수순을 Granlund/Kenner의 GSO를 사용하여 완전 탐색한 후 목적 프로세서에서 실행시 최소의 동적 계수를 갖는 명령 수순을 선택하였다. 제안한 분기 최적화 기법을 SuperSPARC 프로세서와 GNU C 컴파일러를 사용하여 실험한 결과 입력 프로그램에서 최적화 패턴 과 대응하는 조건부 분기의 경우 원래의 컴파일러가 생성하는 최적 코드 수순에 비하 여 25% 이상의 추가적인 수행시간 개선 효과를 얻을 수 있었다. In this paper, a technique for eliminating conditional branches in the compilers for superscalar processors is presented. The technique consists of three major steps. The first step transforms conditional branches into equivalent expressions using algebraic laws. The second step searches all possible instruction sequences for those expressions using GSO of Granlund/Kenner. Finally an optimal sequence that has the least dynamic count for the target superscalar processor is selected from the GSO output. Experiment result shows that for each conditional branch is the input program matched by one of the optimization patterns, the proposed technique outperforms more than 25% speedup of execution time over the original code when the GNU C compiler and the SuperSPARC processor are used.

Objectives: This study was carried out to investigate the protective effect of Coptidis Rhizoma steamed with rice wine (CR) against gastroduodenal mucosal injury through inhibiting inducible nitric oxide synthase (iNOS) activation. Methods: In in vitro experiment, LPS-induced RAW 264.7 macrophages were treated with CR(0.4, 0.6, 0.8, 1.0 mg/ml) and iNOS mRNA expression and nitric oxide (NO) production were measured. In in vivo experiment normal group mice were treated with neither ethanol nor CR. Both control and sample group mice were orally administrated with ethanol. Five hours after ethanol administration control group mice were orally administrated with distilled water, sample group mice were orally administrated with CR. After three days administration, gastroduodenal mucosa of mice was observed histopathologically and iNOS, nuclear factor-kappa B (NF-${\kappa}B$) activation were observed immunohistochemically. Results: In in vitro experiment iNOS mRNA expression and NO production in LPS-induced RAW 264.7 macrophages were decreased by CR dose-dependently. In in vivo experiment, gastroduodenal mucosal injury was repaired by CR and iNOS, NF-${\kappa}B$ activation in gastroduodenal mucosa were decreased by CR. Conclusions: Coptidis Rhizoma steamed with rice wine has a protective effect against gastroduodenal mucosal injury through inhibiting iNOS activation.

선행관계를 고려한 다중버젼을 기반 실시간 동시성 제어 기법

김명호,홍석희(Myoung Ho Kim),Seok Hee Hong 한국정보과학회 1997 정보과학회논문지(B) Vol.24 No.11

본 논문은 실시간 데이타베이스를 위한 다중버젼을 이용한 잠금 기법을 제안한다. 실시간 처리 시스템에서 사용하는 우선 순위를 기반으로 제안하는 동시성 제어 기법은 높은 우선순위를 가지는 트랜잭션을 선호하여 데이타 충돌을 해결한다. 다중버젼과 선행관계를 사용함으로써 동시성을 증가시켰을 뿐 아니라 종료시한을 초과하는 트랜잭션의 수를 줄이고자 시도하였다. 트랜잭션들 간의 직렬성 순서를 의미하는 선형관계의 사용은 불필요한 트랜잭션의 철회를 피할 뿐 아니라 시스템의 성능을 저하시키는 교착상태를 발생시키지 않게 한다. 우선순위를 고려하여 데이타 충돌을 해결하지만 낮은 우선순위의 트랜잭션이라도 종료시점에 가까운 경우 불필요하게 철회되지 않는다. 본 논문에서는 모의실험을 통하여 제안한 동시성 제어 기법의 성능을 비교 평가하였다. This paper investigates a multiversion concurrency control algorithm for real-time databases. Based on a priority cognitive algorithm commonly used in real-time processing, the proposed algorithm resolves data conflicts among transactions in favor of the urgent transactions, I,e., those with higher priority. Our algorithm increases the degree of transaction concurrency while minimizing the transactions that miss their deadlines. This is achieved by using precedence relationships and multiple versions. A precedence relationship, which implies a serialization order among conflicting transactions, is utilized to resolve data conflicts and avoid deadlocks. The algorithm dynamically determines the abortion of lower priority transactions depending on the likelihood of roll-backs and their states of execution. This leads to saving system resources by reducing unnecessry abortion of the lower priority transactions. We present the experimental results of our algorithm, comparing other real-time concurrency control algorithms. It is shown that the proposed algorithm has superior performance to several algorithms for real-time databases.
