  • The relationship between marine environmental improvement and environmental perception of the inhabitants was investigated. For this purpose, the seawater and bottom materials were analysed. Apart from this, the questionnaire surveys were also conducted around the Sun-so coastal area. In order to examine the improvement in the marine environment, 12 monitoring sites, which are located around Sun-so coast and can be divided into two parts such as inland (GW1-GW6) and outland (GW7-GW12) sea, were chosen. All the collected samples were analyzed to find out the quality of seawater (temperature, pH, salinity, dissolved oxygen: DO, chemical oxygen demand: COD and suspend solid: SS), nutrients (total nitrogen: TN and phosphate: $PO_4-P$) and bottom materials (COD, volatile solids: VS) as per the standard analytical procedures. In addition, the questionnaire mainly focused on the following three factors: 1) social economy, 2) dependent environmental awareness and 3) independent environmental awareness related with the environmental education. The monitoring studies indicated that the marine environment of the Sun-so coast showed various trends for analyzing parameter. No significant temporal changes in temperature, pH and salinity were observed. However, the other parameters showed decreasing (COD, SS, TN, $PO_4-P$ and VS) and increasing (DO) trends according to the quality of seawater and bottom materials. The questionnaire survey clearly showed that most of the residents in Sun-so recognized the improvement of marine environment as compared with the situation experienced in the past. The dredging project which is closely related with economic and living conditions of the local residents led to alter the environmental perceptions and attitudes. The survey also indicated that the inhabitants perceived the necessity of the environmental education (87% of respondents) and preferred regular schooling (55% of respondents) as effective and practical education methods.

  • Purpose: This study aims to understand schools' response to infectious disease, perceived problems and suggestions, with regard to the 2015 MERS outbreak in South Korea, in order to improve the infectious disease response system. Methods: Data were collected by focus group interviews with three groups composed of school health teachers, other teachers, and parents in Seoul-located schools. Results: The major theme was "Schools' Discretionary Response in the Absence of the Control Tower." Four major categories and 11 sub-categories were drawn from the findings. Four major categories were as follows: (a) Temperature monitoring caused lots of complaints, (b) Closure decisions were left at the discretion of schools, (c) Precautions are now being more emphasized, and (d) The support system were malfunctioning. Conclusion: The main areas to be improved are as follows: (1) School district offices should have an expanded role in infectious disease response and build cooperative partnerships with health authorities. (2) Preparedness for infectious disease should be strengthened. (3) Temperature monitoring systems should be improved, (4) Closure decisions should be made at a local community level. These are expected to help schools establish advanced infectious disease response systems.

  • In the current paper, an exact solution method is carried out for analyzing the thermo-mechanical vibration of curved FG nano-beams subjected to uniform thermal environmental conditions, by considering porosity distribution via nonlocal strain gradient beam theory for the first time. Nonlocal strain gradient elasticity theory is adopted to consider the size effects in which the stress for not only the nonlocal stress field but also the strain gradients stress field is considered. It is perceived that during manufacturing of functionally graded materials (FGMs) porosities and micro-voids can be occurred inside the material. Material properties of curved porous FG nanobeam are assumed to be temperature-dependent and are supposed to vary through the thickness direction of beam which modeled via modified power-law rule. Since variation of pores along the thickness direction influences the mechanical and physical properties, porosity play a key role in the mechanical response of curved FG nano-structures. The governing equations and related boundary condition of curved porous FG nanobeam under temperature field are derived via the energy method based on Timoshenko beam theory. An analytical Navier solution procedure is utilized to achieve the natural frequencies of porous FG curved nanobeam supposed to thermal loading. The results for simpler states are confirmed with known data in the literature. The effects of various parameters such as nonlocality parameter, porosity volume fractions, thermal effect, gradient index, opening angle and aspect ratio on the natural frequency of curved FG porous nanobeam are successfully discussed. It is concluded that these parameters play key roles on the dynamic behavior of porous FG curved nanobeam. Presented numerical results can serve as benchmarks for future analyses of curve FG nanobeam with porosity phases.

  • Nursing Diagnosis has evolved in the guest to define nursing and its functions. But for the application to clinical practice an unified system of terminology that helps nurses to assess selected data and identify potential or actual client problems is required. Consistent terminology that captures the real meanings of the nursing diagnosis makes oral and written communication more accurate and efficient. Therefore,' this study was performed to deliver a Korean-translated version of the nursing diagnoses through the process of content validity tests and translations. Data collection for the first content validity test was done from June 27, 1996 to August 1. 1996. Among 20 questionnaires only 16 were used for analysis. With the results of content validity, the list of 109 nursing diagnoses were reviewed by two linguists, one specialized in Korean and the other in English. To clear confusion on a diagnostic label "Incontinence" a urology specialist was invited for consultation. From this analysis and discussions a total of 98 nursing diagnoses was delivered and quesitons containing 98. 98 diagnoses were mailed to 741 subjects to test content validity from August 13, 1996 to October 7, 1996. Among 741 questionnaires, 343 were used for analysis. Total mean score of the diagnoses was 4.30 on the 5 point likert scale. The diagnoses that acquired less than 3.50 were "High risk for altered body temperature"(3.34), "Ineffective thermoregulation" (3.34), "Perceived cosntipation"(3.24). "Stress incontinence"(3.42), "Ineffective airway clearance"(3. 48), "Altered sexuality patterns"(3.35).

  • The temporal dark image sticking phenomena are examined and compared for the two different electrode structures such as the face-to-face and coplanar sustain electrode structure. To compare the temporal dark image sticking phenomena for both structures, the differences in the infrared emission profile, luminance, and perceived luminance of the image sticking cells and the non image sticking cells were measured. It is observed that the temporal dark image sticking is mitigated for the face-to-face structure. The mitigation of the temporal dark image sticking for the face-to-face structure is due to the slight increase in the panel temperature induced by the ITO-less electrode structure.

  • To evaluate customer satisfaction of hotel food and beverage products, developing items for the measurement is necessary through studying the properties of food and beverage products. The properties consist of human service, physical and systematic service. Human service includes appearance and uniforms, courtesy and kindness, quickness and precision of the service, well-educatedness, moral sense and etc. Physical service includes the taste of food and beverage, diversity of food and beverage, outlets' cleanness and atmosphere, refinement of fixture, furnishing and table ware, the admission passage to the hotel and parking lot facilities, and etc. Systematic service includes passages of movement to outlet, arrangement of outlet, reservation management system, operation of events and package goods, temperature and ventilation system and etc. The price is also one of important variables to measure customer satisfaction index, so it is included to the investigating items. As shown some hotels have several satisfactory items but most items are unsatisfactory because expected service is better than perceived service. Therefore, the hotels which lack human service need the reinforcement of service education, the hotels which lack physical and systematic services need the improvement, the development and the renovation according to the unsatisfactory items. And the hotels whose price item is unsatisfactory need to consider the policy.
