일반적으로 TPM 전개프로그램은 추진단계가 정하여져 있다. 그러나 생산시스템의 효율을 극대화시키기 위해서는 TPM의 구체적인 추진요령이나 절차 등에 있어서 업종이나 생산방식, 설비의 종류와 상태, 당면하고 있는 문제들이 서로 다르기 때문에 각각의 기업환경에 맞는 추진방식을 선택하여야 한다. 본 연구에서는 TPM을 추진하고 있는 제조업체를 대상으로 KSA가 제시하는 TPM활동별로 2단계로 세분화하여 각 단계별 활동 중에서 어떠한 활동들이 더 중요하다고 인식되고 있는지를 AHP방법을 이용하여 분석하였다. 분석결과 TPM추진의 1단계 활동에 있어서는 개별개선을 가장 중요한 활동으로, 그리고 전체 활동 중에서 가장 중요한 활동으로 현장불합리 개선 및 Loss 개선, 그 다음은 준비 및 5S 활동을 위한 기본조건 체계를 구축하는 활동, 초기 청소 등의 순서인 것으로 분석되었다.

Background: The study is the first of its kind to be conducted in Saudi Arabia (KSA), aiming to analyze the effectiveness of an intervention program in improving the knowledge of oral cancer among the youth. Materials and Methods: A total of 1,051 young Saudis (57% males and 43% females with a mean age of $20.4{\pm}1.98$) were selected using multi-stage cluster sampling. Knowledge assessment was accomplished using a closed-ended questionnaire which was subjected to reliability tests. Prevalence of risk factors in relation to gender was analyzed using the chi-squared test. Effectiveness was calculated by comparing the pre- and post-intervention means, using the two-tailed paired t-test. Multiple logistic regression was employed in order to determine factors associated with awareness of risk habits, signs/symptoms and prevention of oral cancer. The significance level in this study was set at 0.05. Results: Females were seen to be more into the habit of sheesha smoking (3.3% rather than the use of other forms of risk factors. Prevalence of diverse risk factors such as cigarette smoking (20%), sheesha (15.3%), khat (27%) and shamma (9%) was seen among males. Gender and the use of modifiable risk factors among the study sample were significantly (p<0.001) associated with effectiveness of the intervention. The intervention program was highly effective (p<0.001) in improving the knowledge of oral cancer among the youth in Jazan, KSA. Multivariate analysis revealed that age and gender are the most significant factors affecting knowledge. Conclusions: The study gives a direction for further public health initiatives in this oral cancer prone region.

Incoloy 800H, KSA (Kaeri Superalloy)-6, Inconel 600 및 Hastelloy C-276 합금의 용융염에서의 부식거동을 650~85$0^{\circ}C$ 온도범위에서 조사하였다. LiCl-Li$_2$O혼합용융염에서의 부식은 Li$_2$O에 의한 염기성 용해 기구에 의해 진행되며, 부식속도가 LiCl에서보다 훨씬 빠르게 나타났다. 혼합용융염 LiCl-Li$_2$O에서는 Ni기 합금의 부식속도가 Fe기 합금보다 빠르고, Mo와 W의 함량이 높은 Hastelloy C-276이 가장 빠른 부식속도를 나타내었다. 용융염 LiCl에서는 LiCrO$_2$의 단일 부식층이 형성되고, LiCl-Li$_2$O 혼합용융염에서는 산화물과 Ni의 2상구조의 다공성 부식층이 형성되었다.

2009학년도 한국과학영재학교 신입생 143명의 자기소개서와 지도 교사와 교수가 관찰한 학생들의 영재성 사례와 관찰 기록을 담은 추천서, 학부모의 학생에 대한 관찰기록지를 컴퓨터 보조 질적 분석 체계(Computer Assisted Qualitative Date Analysis System)를 이용한 질적 분석을 통해 과학 영재에게서 나타나는 행동 특성을 알아보았다. 연구 결과 과학 영재의 행동 특성을 5개의 주요 범주로 나눌 수 있었다. 본 연구는 외국의 연구와 양적 연구에 의존한 기존의 영재의 행동 특성 연구를 보완해줄 뿐 아니라 영재성의 구체적인 영역으로서 과학 영재의 행동 특성을 파악할 수 있게 하여 과학 영재를 판별 도구 및 교수학습 프로그램의 개발에 유용한 자료로 이용될 수 있을 것이다.

The outbreak of COVID-19 had affected almost every part of the world and caused disastrous results, the number of reported COVID-19 cases in past few months have reached to more than 29 million patients in the world globally. This pandemic has adversely affected all the activities of life, ranging from personal life to overall economic development. Due to the current situation, routinely turned to online resources, and people have relied on technology more than they have been before. Since cybercriminals are an opportunist and they utilized this entirely, by targeting the online services for all sectors of life. This fortnight online dependency of the community over the internet opened several easy doors for the cybercriminals. This causes exponential attacks over internet traffic during this epidemic situation. The current Covid-19 pandemic situation appeared at once, and no one was ready to prevail this. However, there is an urgent need to address the current problem in all means. . KSA is among one of the countries most affected by these CA and is a key victim for most cyber-crimes. Therefore, this paper will review the effects of COVID-19 on the cyber-world of KSA in various sectors. We will also shed light on the Saudi efforts to confront these attacks during COVID -19. As a contribution, we have provided a comprehensive framework for mitigating cybersecurity challenges.

This study distinguished innovation activities into 3 main things (sustainability management activity, management innovation activity and quality innovation activity). Performance differences among those 3 innovation activities are again distinguished into 4 things (affecting on sales revenue, increasing productivity, improving its corporate image and cost reduction) to demonstrate recognition of performance. We also demonstrated difference of performance between manager and other workers.

Objective: The aim of this study was to assess the level of cancer awareness after delivering educational programs by assessing the awareness in regard to the role of microbial infectious agents in the etiology of some cancers. Methodology: Data were collected during Cancer Awareness and Educational Programs which were conducted at various places such as schools, clubs, mosques and Government health centres. This survey included 200 participants. Results: Of the persons who responded to the question, whether some viruses, bacteria, parasites and fungi, can cause cancer, 111/134 (82.8%), 105/129 (81.4%), 102/124 (82.8%) and 95/122 (77.8%), respectively, answered yes. Conclusion: The level of cancer awareness is low amongst Sudanese northern state inhabitants even after delivering an educational program.

The market performance of WiBro in Korea has not been as expected, and its rapid diffusion in the near future is unlikely owing to the existence of competing services. There has been little research on the factors affecting this low market diffusion. This study is based on an analytical framework in which a lack of service capability and the insufficiency of service-related activities have resulted in the current poor market performance. An expert survey was conducted on WiBro specialists and verified using the analytical hierarchy process method. The result of this analysis is as follows: underinvestment in network deployment and marketing, insufficient promotional policies, and a shortage of service capabilities are to be analyzed as the main causes of WiBro's low market diffusion.

The concept of quasi-coincidence of interval valued intuitionistic fuzzy point with an interval valued intuitionistic fuzzy set is considered. By using this idea, the notion of interval valued (α, β)-intuitionistic fuzzy bi-ideals, (1,2)ideals in a semigroup introduced and consequently, a generalization of interval valued intuitionistic fuzzy bi-ideals and intuitionistic fuzzy bi-ideals is defined. In this paper, we study the related properties of the interval valued (α, β)-intuitionistic fuzzy bi-ideals, (1,2) ideals and in particular, an interval valued (Є, Є ∨q)-fuzzy bi-ideals and (1,2) ideals in semigroups will be investigated.

In recent years, the safety of customers and the demand for rights to be protected from the risk have become stronger than ever day by day, and the function concerning product liability(PL) and quality assurance(QA) has been emphasized. Basically these functions can be obtained by inspection and there is the single rectifying sampling inspection for attribute (KSA-3105) as an existing method. But we can not say this method is good enough because of limitations in the range of applications and the approximate design of inspection methods which can not meet the rapidity and accuracy of quality information transfer according to the maturity of information period. Therefore, in this paper, a new algorithm is developed which can design the accurate inspection method by using the linear cost function that has not been considered in the existing inspection methods. Also in addition to this, a optimal rectifying sampling inspection plan, contributing to minimize the total costs, can be developed by programming the algorithm developed in this study and it can be applied to any field having many processes almost limitlessly.
