Molecular docking is a critical event which mostly forms Van der waals complex in molecular recognition. Since the majority of developed drugs are small molecules, docking them into proteins has been a prime concern in drug discovery community. Since the binding pose space is too vast to cover completely, many search algorithms such as genetic algorithm, Monte Carlo, simulated annealing, distance geometry have been developed. Proper evaluation of the quality of binding is an essential problem. Scoring functions derived from force fields handle the ligand binding prediction with the use of potential energies and sometimes in combination with solvation and entropy contributions. Knowledge-based scoring functions are based on atom pair potentials derived from structural databases. Forces and potentials are collected from known protein-ligand complexes to get a score for their binding affinities (e.g. PME). Empirical scoring functions are derived from training sets of protein-ligand complexes with determined affinity data. Because non of any single scoring function performs generally better than others, some other approaches have been tried. Although numerous scoring functions have been developed to locate the correct binding poses, it still remains a major hurdle to derive an accurate scoring function for general targets. Recently, consensus scoring functions and target specific scoring functions have been studied to overcome the current limitations.

Purpose: This study aimed to compare the effect of chest compression and the resulting ventilation volume in walking cardiopulmonary resuscitation (CPR), straddling CPR, and mechanical CPR while moving manikins to main stretchers. Methods: We compared the chest compressions in terms of compression depth, number of incomplete releases, complete release depth, compression rate, duration between peak time of previous compression and peak time of current compression, and respiration. We analyzed the compression comparatively with the ventilation volume in three different types of CPR. Results: The chest compression depth was significantly improved during straddling CPR as compared to walking CPR, during which women were unable to achieve sufficient chest compression depth. A constant chest compression depth was maintained during mechanical CPR. Conclusion: High-quality chest compressions were difficult to achieve in moving spaces. Further, walking CPR may be helpful in men, but straddling or applying automatic chest compressions in women would result in more effective CPR. Our findings demonstrate the limitations and trends in administering CPR in men and women, which may be useful in devising better education and training methods in the future.

Purpose: The purpose of this study was to analyze the concept of nurses' safety within the context of the hospital environment. Methods: We used Rodgers' method of evolutionary concept analysis and reviewed the relevant literature and noted and categorized characteristics that appeared frequently. Results: Nurses' safety was defined as safe status and safe activity among nurses. Three key defining attributes were identified as: (a) the minimization of actual or perceived risk, (b) personal duties and rights, and (c) ensuring within a safe working environment. Antecedents of nurses' safety were categorized into three dimensions: (a) individual, including vigilance and knowledge gained through education and training; (b) institutional, including safety provision in the organizations; and (c) national, including legislation. The outcomes of nurses' safety included the following: (a) continued competence in nurses' work; (b) enhancement of the quality of patient care; and (c) reductions in nurses' turnover rates. Conclusion: Nurses' safety ensures that qualified nurses are able to continue to perform their duties and provide good patient care. The findings of this study could contribute to future research examining nurses' safety. In addition, appropriate tools must be developed to measure the concept.

According to this study, Korean food department rather than Western food department and business department rather than food & beverage department is more separated with the greater difference. It is surveyed that the main reason to separate from food service is dissatisfaction to wage followed by six reasons. In the light of management the separation of employees gives management a positive aspect, but the separation of necessary employees bring about a big problem. That the separation rate of food service industry which greatly depends on personal service is high causes many bottleneck to development of food service industry. If the saparation rate of employees is high, it is difficult to maintain consistency of service quality. It is impossible to think that immature service new employee gives customer strong impression. Subsequently the spending of time and cost to train new employees and management reproaching supervisors makes morale of employees dropped. That is why the very this influences selling. To improve the vicious cycle of that serve absence in food service Operators of food service industry should be escaped from their fixed ideas. It is time to need management consciousness which wants to have real content rather than external growth. It is revealed that more than 80% of investment of most of food service industry goes to facility investment. A part of the investment cost should be invested to foster professional manpower. And if employees can have owner consciousness by continuous support and positive investment in training which can give real intention to their lives and vocational pride, it is believed that the future of food service industry in Korea is promising.

The purpose of this study is to apply to the phenomenological self-evaluation method in the social welfare agency. It means that the phenomenological self-evaluation method accepts "the reality" which occurs in the social welfare setting, and functions for the social worker to play dual role of practitioner-evaluator. This paper examines two dimensions of social work evaluation theory and practice. Firstly, this study is to investigate a trend of evaluation in social work setting, and seeks theoretical aspect of phenomenological self-evaluation method, with emphasis on the strength and limit of the positivism evaluation methods. Although qualitative evaluation was suggested to make an alternative to the positivism by qualitative researchers, they did not suggest the specific methods and roles of the practitioner-evaluator. In this study, two directions of the phenomenological self-evaluation method are suggested to overcome the limitations. which are "environment-relation self-evaluation" and "program-oriented self-evaluation". Secondly, the result of phenomenological self-evaluation studies for the social welfare community center program and organization in kangnam district from June, 1994 (Program-oriented self-evaluation) to march, 2000 (Environment-relation self-evaluation) are presented. the phenomenological self-evaluation study showed the expected outcome such as; reflective self-training, making a practice knowledge, enhancing service quality, and reinforcing the identity of social welfare profession.

LPG (Liquefied Petroleum Gas) vehicles in metropolitan area are being applied to improve air quality and have been proven effective for the reduction of air pollutant. In addition, the demand of gas as an eco-friendly energy source has being increased. With the LPG filling station is also increasing every year. These gas stations are required to install the securest storage tank because of possibility of causing huge loss of life and property. Therefore, in this paper, underground containment type is proposed as installation of the LPG storage tank using Taguchi method, which is considered to be more safe, economical, efficient, easy checking and simple construction method than any other. If leakage, economics, real estate utilization rate, safety, easy to check, simple construct about above ground, buried underground and underground containment storage tank are analyzed by Taguchi method, real estate utilization rate, economic and safety in turn are improved. Therefore, the underground containment storage tank is a optimal installation technology.
