A differentiated training considered the individual traits of a security guard in order to achieve the self-realization as well as to fulfill the spiritual needs of a security guard is needed. To promote the development of security industry in the new millennium, new types of training methods should be introduced, and a planned elaborate training in consideration of the traits of individual security guards is needed. On the other hand, to cultivate occupational consciousness, and to increase training products, a specific kind of training based on the survey of demand should be carried out. In this study, I made an actual analysis current training contents derived from the questionnaires and interviews among the security guards who were employed at the security industry. From these analyses, I am going to suggest the following measures; 1) The improvement of circumstances in training should be preceded. 2) Training related to practical business in consideration of individual traits should be emphasized. 3) Producing excellent professionals and developing specific textbooks are needed. 4) To establish professional education institutes is urgently needed. 5) Systematic training methods sponsored by government authorities and security society should be established. 6) The deep concern of security industry employers about the importance of training is needed.

In spite of highly advanced paint coating techniques, corrosion damage of marine metal and alloys increase more and more due to inherent micro-cracks and porosities in coatings formed during the coating process. Furthermore, flowing seawater conditions promote the breakdown of the protective oxide of the materials introducing more oxygen into marine environments, leading to the acceleration of corrosion. Various corrosion protection methods are available to prevent steel from marine corrosion. Cathodic protection is one of the useful corrosion protection methods by which the potential of the corroded metal is intentionally lowered to an immune state having the advantage of providing additional protection barriers to steel exposed to aqueous corrosion or soil corrosion, in addition to the coating. In the present investigation, the effect of flow velocity was examined for the determination of the optimum corrosion protection current density in cathodic protection as well as the corrosion rate of the steel. It is demonstrated from the result that the material corrosion under dynamic flowing conditions seems more prone to corrosion than under static conditions.

Objectives: The purpose of this study was to explore the general public's perception and status of oral muscle strength training, to develop age-appropriate educational media and training methods, and to promote the need for oral muscle strength training. Methods: Data were collected from 15 individuals across different age groups (young, middle-aged, and elderly) from December 2022 to February 2023 through focus group interviews, and they were conducted twice for each group in a face-to-face manner. Results: Four key categories were identified: lack of information, effectiveness of training, need for promotion, and factors necessary for implementation. The following themes emerged: lack of information, need for training, age-specific characteristics, need for repetition, age at which training is needed, lack of promotion, need for promotion, number of practitioners, willingness to practice, and appropriate media for training. Conclusions: Awareness of oral muscle strength training was found to be very low, and it is necessary to improve awareness through continuous information and appropriate education on its need among the public. Additionally, quality content or media that can be easily applied for effective training should be developed, and personnel who can perform training efficiently should be trained.

A primary objective in creating a stratified thermal storage is to maintain the thermodynamic quality of energy, so thermally stratified energy can be extracted at temperatures required for target activities. The separation of the thermal energy in heat stores to layers with different temperatures, i.e., the thermal stratification is a key factor in achieving this objective. This paper introduces different methods that have been proposed to characterize the thermal stratification in heat stores. Specifically, this paper focuses on the methods that can be used to determine the ability of heat stores to promote and maintain stratification during the process of charging, storing and discharging. In addition, based on methods using thermal stratification indices, the degrees of stratification of stored energy in Lyckebo rock cavern in Sweden were compared and the applicability of the methods was investigated.

It is an urgent time to give impetus to an ecological understanding of relationship between man and environment and to promote an action to preserve environment. This paper is to examine factors which give influence to environmental education environmental consciousness and environmental behavior of housewives. The subjects of this study are 806 Seoulite housewives. A questionaire is used as the survey method and the statistical methods such as frequency percentage ANOVA multiple regression path analysis have been applied for research. Major findings are summarized as follows: Major findings are summarized as follows: When environmental education program is relatively low differences are shown according to variables of age, education and occupation. Second, when environmental consciousness is high differences are shown according to variables of age education income and housing. Third when environmental behavior is low group difference is shown only according to age. Relative influence to environmental behaviour is shown in the order of spare-life type environmental education environmental consciousness socio-oriented type fashion-oriented type and age difference.

Objectives: An inadequate understanding of infertility can affect individuals' self-efficacy and ability to perform self-care; thus, reproductive health education is an important part of infertility treatment. The present qualitative study aimed to explore the experiences and educational needs of infertile women with regard to reproductive health. Methods: In this qualitative study, we utilized a content analysis approach. Purposive sampling was performed to ensure maximum diversity. In total, 23 individual interviews were conducted with 20 Iranian women with infertility and 3 key informants between July 2018 and February 2019 in northern Iran. Data were collected through in-depth, semi-structured interviews. Data analysis was performed using a conventional content analysis approach. Results: Reproductive health education needs were identified by analyzing interview data from 4 main categories: familiarity with the fertility process and preparation for pregnancy, recognition of infertility and expectations around seeking treatment, recognition of preventive actions associated with reproductive health, and correction of false beliefs. Recognizing the causes of infertility and understanding the different approaches to infertility treatment are among the most important educational needs of infertile women. The potential for neglect of health-related issues due to concerns about fertility and the maternal experience necessitates education about preventive measures for cervical cancer, breast cancer, and sexually transmitted infections. Correcting misconceptions, including those related to contraceptives and traditional medicine, can also help promote reproductive health. Conclusions: In infertile women, the educational needs associated with reproductive health are multifaceted. Satisfying these needs can help achieve optimal treatment results and promote reproductive health.

Low-rank representation methods already achieve many applications in the image reconstruction. However, for high-gradient image patches with rich texture details and strong edge information, it is difficult to find sufficient similar patches. Existing low-rank representation methods usually destroy image critical details and fail to preserve edge structure. In order to promote the performance, a new representation-based image super-resolution reconstruction method is proposed, which combines gradient domain guided image filter with the structure-constrained low-rank representation so as to enhance image details as well as reveal the intrinsic structure of an input image. Firstly, we extract the gradient domain guided filter of each atom in high resolution dictionary in order to acquire high-frequency prior information. Secondly, this prior information is taken as a structure constraint and introduced into the low-rank representation framework to develop a new model so as to maintain the edges of reconstructed image. Thirdly, the approximate optimal solution of the model is solved through alternating direction method of multipliers. After that, experiments are performed and results show that the proposed algorithm has higher performances than conventional state-of-the-art algorithms in both quantitative and qualitative aspects.
