This study is a descriptive research study to identify Unmet Dementia Information Needs (UDIN) for caregivers of dementia patients at Dementia Relief Center and to understand the effectiveness of the program for workers. The subjects were 114 caregivers and 217 practitioners from dementia relief centers in 25 autonomous districts of S city from November 1, 2019 to January 31, 2020. The UDIN questionnaire is a 7-point Likert scale. The Crisis Management Questionnaire is a Likert 5-point scale consisting of 10 questions from 6 categories. As a result of the study, the proportion of depressed caregivers experiencing UDIN was 12.3times higher than those who did not (p<.001). The program effectiveness was 8.98times better than those who perceived the lack of risk management as good (p=.004), and social workers were 2.81times better than nurses (p=.091). It is necessary to conduct interactive operations to meet the needs of the community residents by listening to their diverse opinions rather than simply implementing a one-sided policy to raise the service of a dementia relief center to the highest level in a short period of time.

Purpose: The purpose of this study was to analyze the reason to select complementary and alternative therapy for terminally ill cancer patients. Methods: The data were collected from 21 terminal cancer patients and families through the in-depth interview. Data analysis were performed by the Colaizzi's phenomenological method (1976). Results: The reason to select complementary and alternative therapy for terminal cancer patients and families was then categorized with 4 elements; Awareness of limitations in contemporary medical treatments, Belief in effectiveness of the CAM, Satisfaction with emotional needs of family members, and Disbelief due to negative attitudes of physicians. The result indicated the following 9 themes expectation for a complete cure, uncertainty in hospital treatments, complementary method for management of side effect of chemotherapy, alleviation of symptoms and life-sustaining, fear for side effects of cancer treatments, belief in earned information, referrals by other, responsibility of family, and dissatisfaction with negatine attitudes of physicians. Conclusion: Physicians should provide a sufficient explanation and try to effectively communicate with clients about hospice and palliative service and the CAM. We strongly realized that concerns about patients' best care and satisfactions with family's needs should be understood.

Purpose: This study was conducted to investigate how nurses who take care of terminal patients perceive fluid therapy and how this therapy is currently being used in hospitals. Methods: This survey included 200 nurses, 87 of whom were working in the oncology units of 3 university hospitals in Seoul, Korea, and 113 were working in 18 hospice centers. The data for this study were collected by means of structured questionnaires and analyzed by using the Statistical Analysis System software. The differences in perception towards fluid therapy between nurses working in oncology units and those working in hospice centers were examined using the $x^2$ test and analysis of covariance. Results: Fluid therapy was perceived more negatively by the nurses from hospice centers than by those from oncology units. Continuous subcutaneous infusion was used in hospice centers, but not in oncology units. In addition, the average amount of fluid infused daily differed significantly between the oncology units and hospice centers. Conclusion: Our results show that there were differences in the perception towards fluid therapy between nurses in different clinical settings. Nurses caring for terminal and palliative care patients should not simply provide or withhold fluid therapy, but rather develop a wider range of views on fluid therapy, focusing on effective alternative interventions.

Purpose: This study was conducted to explore predictors of health status of family caregivers of hospice patients. Methods: This study included 118 family caregivers of patients who were admitted to the hospice ward of three general hospitals in D city. The collected data were analyzed by frequency, percentage, t-test, one-way ANOVA, Pearson's correlation coefficients, and stepwise multiple regression using the SPSS WIN 18.0 program. Results: The mean score for overall health of family caregivers was 2.68 (${\pm}0.42$). Mean scores for variables related to health were 2.55 (${\pm}0.37$) for sleep quality, 1.91 (${\pm}0.41$) for anxiety and 2.78 (${\pm}0.33$) for hope. Variables such as sleep quality, gender, anxiety and hope explained 59.8% of variance among family caregivers' health conditions. Conclusion: These results suggest the need for nurses to search for ways to promote health of hospice patients' family caregivers, such as improving the quality of sleep, easing their anxiety and encouraging hope.

Photodynamic therapy (PDT) is a great potential approach for the localized tumor removal with fewer metastatic potentials and side effects in treating the disease. In the treatment process, a photosensitizer (PS) that absorbs a light energy to generate reactive oxygen is essential. In general, a visible light is used as a light source of PDT, so that side effects from the light source are inevitable. For this reason, upconversion nanoparticles (UCNPs) using near-infrared (NIR) as an excitation source are attracting attention in the field of disease diagnosis and treatment. UCNPs have the low cytotoxicity and phototoxicity, and also advantages such as deep tissue penetration and low background autofluorescence. For PDT, UCNPs should be combined with a PS which absorbs the light energy from UCNPs and transfers it to the surrounding oxygen to produce reactive oxygen. In addition, the therapeutic efficacy can be improved by modifying nanoparticle surfaces, adding anti-cancer drugs, or combining with photothermal therapy (PTT). In this review, we summarize the recent research to improve the efficiency of PDT using UCNPs.

The purposes of this study were to identify the misconceptions that students have on the magma and plate tectonics and to present the implications in developing textbooks as well as related curriculum of high school textbooks. Data were collected through questionnaire, consisting of some questions, short essays, and descriptive drawings, developed by the research team. A total of 140 high school students(9th graders) responded to those questionnaires and were interviewed for further information. It was reported that participants displayed various misconceptions related to magma and plate tectonics. The identified misconceptions are as follows: For the definition of magma, the 31% of participants misunderstood magma as lava. In respect to the generative mechanism of magma at subduction zone, over 90% of students responded that it is generated by frictional heat. The source of misconceptions were identified as a result from textbooks and related reference-books. For the concept of plates, 87% of students conceived 'crust or a lower part of the plates' as 'plates'. Most participants hold the right concept of oceanic ridge, whereas, 66% of them considered 'rift valley' as either 'divergence of continental plates' or 'converging boundary'. 63% of them defined 'collision boundary of continental plate' as either 'subduction zone' or 'diverging boundary'. For the definitions of the trench and Benioff zone, 86% of students responded them as the place of subduction or differing density between two converging plates. The students' misconceptions were resulted from the errors and insufficient explanation, inappropriate figures, and data presented in textbooks, reference-books, lecture, and web sites. The results of this study are implied to contribute the improvement of students' misconceptions.

The vibration or/and noise generated by blast operations might cause not only structural damage to properties but mentally also to humans and animals. For that reason, maximum permitted vibration and noise levels are set by sensitivities of structures and they are used for the management of blast vibration. It is known that the fish lived in water are more sensitive to vibration than land animals, and thus the adverse impact of the blasting on fish farms should be very concerned. This study investigated the vibration and noise levels at a large eel farm located some 840 meters of the blasting site through the large real-scale experiments of blastings, prior to conducting the actual blasting. As a result, it was found that the noise met the requirement to be within maximum permitted level, while the ground vibration exceeded the permitted vibration. Accordingly, the impact of the excess vibration was investigated by an existing empirical method and verified by a new three dimensional numerical analysis. In this study, such an inspection process was briefly described, and a method was suggested for the examination of possible adverse effects from blasting on vibration-sensitive structures like the eel farm. The study also introduced a design method that controls the blast effects - ground vibration and noise.

Objectives: This study was performed to compare rural residents' perceived health status and life satisfaction according to their general and health related characteristics and to identify factors related to perceived health status and life satisfaction in this population. Methods: Subjects were 1,091 adults aged 20 years or older living in Geochang Gun, South Korea. A survey was conducted from June 28 to August 25, 2009. We used the health self rating scale by Lawton et al. (1982) and the overall life satisfaction scale by Wrosch et al. (2000). The collected data were analyzed using SPSS WIN 18.0. Result: Sex, age, education, spouse, medical diagnosis, currently taking medication, main health maintenance behavior, alcohol consumption, frequency of alcohol consumption, exercise, family harmony, and friend relationships were significantly related to perceived health status. Age, education, spouse, main health maintenance behavior, smoking, exercise, family harmony, and friend relationships were significantly related to life satisfaction. Further, 29.3% of the variance in perceived health status could be explained by medical diagnosis, exercise, family harmony, education, currently taking medication, and friend relationships, while 11.1% of the variance in life satisfaction could be explained by family harmony, perceived health status, main health maintenance behavior, and friend relationships. Conclusion: Health management programs must be designed so as to incorporate the general and health related characteristics of rural residents if they aim to improve the perceived health status and life satisfaction in that population.

The purpose of this study is to investigate the gender discourse of Korean newspapers. For this, the study analyzes the frames of frames of crime news on Chosun Daily and Hangyurae Newspaper for 2 years. The data are collected using KINDS, and include 265 crime articles involving woman. According to the results of this research, the episodic frames are used in the most of crime news. The five frame devices are founded in the episodic frame articles; the male subjectivity and the female objectivity, the male-oriented perspectives which reporters have, the abused sexual details and sensationalism, the emphasis of women body's fragility which imply woman's unavoidability as victims, and finally, blaming women who are victims of crimes. And in the articles of thematic frames, the similar frame devices are found. In particular, they only emphasize the problem of crime and fail to suggest a concrete resolution. Finally, the study discusses the findings relating to the patriarchal news making convention and the commercialism of newspaper industry. The two newspapers have been pursuing quite different political lines in Korean society. It is generally considered that Hangyurae newspaper is progressive and Chosun Daily is conservative. However, this study reveals that the way dealt with women in the crime news are not different. It is concluded that Korean newspapers still produce the gender discourse based on male-centric perspective and patriarchal ideology.

The purpose of this study is to analyze the 1st and 2nd Korea Earth Science Olympiad (KESO) items, in order to find informations to enhance item quality. To do this, internal and external item classification frameworks are developed. Item difficulty (P), discrimination index (DI), correlation, and reliability are estimated by using classical test theory. Generalizability is also estimated by applying the generalizability theory. The results of item classification are as follows: (1) ‘Geology’, ‘astronomy’ and ‘data analysis and interpretation’ are dominant in content and inquiry process domain, respectively. Nearly every item has textbook context. (2) There is no difference between the preliminary and final tests in terms of their thinking skills sections. (3) As a whole, the ratio of items with pictures is high in item representation. However, multiple-choice and short answer items are more common in preliminary competition, and essay type items are found more often in final competition. The ratio of simple items is high in middle school section and preliminary competition, but composite items are dominant in high school section and final competition. The findings of item analysis are as follows: (1) In the middle school section, P is low and DI is moderate. But in the high school section, there is a considerable differences between science high schools and other high schools in general. (2) The highest correlation is reported between the scores of meteorology domain and total score in middle school, whereas in high school astronomy domain and total score show the highest correlation. (3) General high school section show the highest Cronbach $\alpha$ and generalizability. (4) General high school section show acceptable generalizability coefficient (> 0.80), but middle and science high school section should increase the number of items to reach acceptable generalizability level.
