Objectives: To evaluate the effectiveness of reflexology foot massage (RFM) to improve quality of life and reduce anxiety for hospitalized cancer patients undergoing chemotherapy. Methods: This study was conducted at the East-West Cancer Center at Daejeon University; Using an waiting list and non-treatment control research design, we compared the results of control group and to that of the experimental group. The study consisted of 14 hospitalized cancer patients being admitted to the East-West Cancer Center of Daejeon University Dunsan Oriental Hospital in Korea. We measured FACT-G (Functional Assessment Cancer Therapy-General) and STAI (Spielberger State-Trait Anxiety Inventory) scale before, after and 48 hours after the intervention. The patients received 30 minute RFM 5 times a week. Results: There was an average increase on the FACT-G, Physical, total scale and decrease of STAI 1 scale in the treatment group compared with control group (P < 0.05). Anxiety in the treatment group showed significant decrease compared to control group. It suggests that RFM may alleviate cancer-related anxiety and contribute to the improvement in quality of life among cancer patients. Therefore, there was limited equivalences with experimental group. Conclusions: We concluded that RFM can be considered a supportive treatment used in combination with chemotherapy.

This study aims to suggest the methodology for conservation of excavated costumes especially repair and restoration process. Early excavated costumes had not attracted attention from the field of academia and the public. So not many scholars, organization and society participated in the excavations but as its value has gotten more recognition, there has been a reversal in trend. And so many organizations have taken part in it. Excavating includes conservation processes such as washing, repair and restoring, and then it is published by reports or books after the process is complete. However the method of conservation has varied depending on the institution. In particular, repair and restore methods do not include anything specific details, and often times, only has descriptions of the before and after state, and so a more unified method needs to be suggested and shared. This study defined 'Conservation', 'Repair' and 'Restoration' and then applied it to the short history of Korean excavated-costumes. Then it suggested ways to repair and restore excavated-costumes in terms of construction, textile, and damage by the unpublished cases of excavated-costumes of Noh Su-ham(1516~1573)'s Family. It was also referred to repair and restoration process such as shaping correction, dyeing, supporting, sewing and after treatment by texts and pictures. Other contents such as a list of relics and its details, will be published through a report or a book. The whole process of conservation was in progress based on the ethical guidelines of conservation, 'Minimum intervention' and 'Reversibility'.

PURPOSE : This study attempts to find the effects of water perturbation exercise performed on stroke patients in their physiological cost index and gait ability tests. METHOD : The subjects were 30 stroke patients, water perturbation exercise group was performed 3 day per week, for 40 minutes a day, for a period of eight weeks. The physiological cost index and gait of all subjects were assessed by using the polar, 6 Minute Walk Test (6MWT), and 10 meter Walk Test(10mWT) at pre training and post training. Paired t-test was used to analyze change before and after intervention in group. Pearson's correlation was used to analyze correlation of all variables. RESULT : Water perturbation exercise group showed increased physiological cost index. Water perturbation exercise increased gait ability, showing a significant difference. Showing the correlation between the relatively high amount between physiological cost index and 6 minutes walking test. CONCLUSION : From the result of the study, we found that water perturbation exercise was effective in improving physiological cost index and gait ability. The patient is considered to be used by itself to involve the treatment and the risk of falling from the lowered state into the treatment method for the intensive treatment of stroke patients to be useful in improving the cardiovascular system and ability to walk. Through underwater training for stroke patients in the future on the basis of this study it is considered to require additional clinical studies on the impact on daily living and quality of life of stroke patients.

The adsorption and decomposition of trimethylene oxide ($C_3H_6O$) molecule on the Al(111) surface were investigated by the generalized gradient approximation (GGA) of density functional theory (DFT). The calculations employed a supercell ($6{\times}6{\times}3$) slab model and three-dimensional periodic boundary conditions. The strong attractive forces between $C_3H_6O$ molecule and Al atoms induce the C-O bond breaking of the ring $C_3H_6O$ molecule. Subsequently, the dissociated radical fragments of $C_3H_6O$ molecule oxidize the Al surface. The largest adsorption energy is about -260.0 kJ/mol in V3, V4 and P2, resulting a ring break at the C-O bond. We also investigated the decomposition mechanism of $C_3H_6O$ molecules on the Al(111) surface. The activation energies ($E_a$) for the dissociations V3, V4 and P2 are 133.3, 166.8 and 174.0 kJ/mol, respectively. The hcp site is the most reactive position for $C_3H_6O$ decomposing.

Objectives : This study aimed to investigate the associations between physical disorders and prevalent/incident suicidal ideation in a community dwelling older population aged 65 years or over. Methods : 1204 people aged 65 years or over evaluated at baseline. Suicidal ideation was identified using the questions from the community version of the Geriatric Mental State Schedule ("GMS B3"). Reported physical disorders covering 11 common and generally chronic health problems were ascertained. Covariates included were depression, age, gender, years of education, accommodation status, past occupation, and current occupation. Of 1066 without suicidal ideation at baseline, 805 (76%) were followed 2 years later, and incident suicidal ideation was evaluated. Results : Prevalent suicidal ideation was significantly associated with 4 of 11 physical disorders: eyesight problems, persistent cough, heart disease and paralysis or weakness in one leg or arm. Incident suicidal ideation was associated with 3 physical disorders: asthma, high blood pressure and paralysis or weakness in one leg or arm. Both prevalent and incident suicidal ideation were significantly associated with increased number of physical disorders. Conclusions : Certain physical disorders were comorbid and precipitating factors of suicidal ideation in elders. And appropriate intervention and treatment of physical disorders might prevent suicidal ideation in elderly.

A detailed computational fluid dynamics (CFD) simulation analysis model was developed using ANSYS CFX 16.1 and analyzed to simulate the basic design and internal flow characteristics of a 180 MW small modular reactor (SMR) with a natural circulation flow system. To analyze the natural circulation phenomena without a pump for the initial flow generation inside the reactor, the flow characteristics were evaluated for each output assuming various initial powers relative to the critical condition. The eddy phenomenon and the flow imbalance phenomenon at each output were confirmed, and a flow leveling structure under the core was proposed for an optimization of the internal natural circulation flow. In the steady-state analysis, the temperature distribution and heat transfer speed at each position considering an increase in the output power of the core were calculated, and the conceptual design of the SMR had a sufficient thermal margin (31.4 K). A transient model with the output ranging from 0% to 100% was analyzed, and the obtained values were close to the T_hot and T_cold temperature difference value estimated in the conceptual design of the SMR. The K-factor was calculated from the flow analysis data of the CFX model and applied to an analysis model in RELAP5/MOD3.3, the optimal analysis system code for nuclear power plants. The CFX analysis results and RELAP analysis results were evaluated in terms of the internal flow characteristics per core output. The two codes, which model the same nuclear power plant, have different flow analysis schemes but can be used complementarily. In particular, it will be useful to carry out detailed studies of the timing of the steam generator intervention when an SMR is activated. The thermal and hydraulic characteristics of the models that applied porous media to the core & steam generators and the models that embodied the entire detail shape were compared and analyzed. Although there were differences in the ability to analyze detailed flow characteristics at some low powers, it was confirmed that there was no significant difference in the thermal hydraulic characteristics' analysis of the SMR system's conceptual design.

The IUU Fishing Index is composed of 40 indicators. These indicators were grouped by state responsibilities (flag, coastal, port, and general including market) defined in the FAO IPOA-IUU (2001) and then by type into vulnerability, prevalence, and response. A total of 152 coastal nations was surveyed. Korea's total combined IUU Fishing Index was 2.49 in 2019 and 2.91 in 2021, indicating a drop in the ranking to the third worst out of 152 countries followed by China and Russia in 2021. The indicators that increased the IUU fishing risk in 2021 compared to 2019 included seven indicators of prevalence and two indicators of response while those reducing the risk included one prevalence and one response indicator. The IUU Fishing Index revealed that many fisheries observers and monitoring, control and surveillance (MCS) practitioners active in the waters of RFMOs jurisdiction where Korean distant water vessels operate have mentioned concerns about the compliance with RFMO conservation measures or fishing practices. It suggested that strengthening management intervention in the fishing sector is needed. The primary tool for management is the MCS system. Given the logistical difficulty of oversight from land, air and at-sea, there is a need to enhance MCS strategies through logbook data, at-sea observer and electronic monitoring program. It also suggested that MSC fisheries certification and fisheries improvement projects, which are widely used for improving fishing sector performance, could contribute to the eradication of IUU fishing and the promotion of sustainable distant water fisheries.

Purpose: This study attempted to understand health behaviors and analyze the association of the health behaviors with musculoskeletal diseases in adults. Method: The subjects of this study were 6,946 adults aged between 20 and 65 who had participated in the 2001 National Health Nutrition Survey. The instrument was composed of Health Interview Survey (HIS), Health Behavior Survey (HBS) and Health Examination Survey (HES), which were used in the 2001 National Health Nutrition Survey. Data were analyzed using SPSS 10.1 by applying $x^2$ and multivariate logistic regression. Results: 1. The present smoking rate was 46.5% and the present drinking rate was 81.2%. 2. Of the subjects, 22.7% were overweight ($BMI{\geq}25$), and 28.1% were exercising regularly. 3. Major factors affecting musculoskeletal diseases were low education, poor economic state, smoking, and BMI. Middle school graduates were 2.54 times more likely to have musculoskeletal diseases than college graduates. The risk was 1.83 times higher in indigent respondents than in affluent ones, and 1.43 times higher in smokers than in non-smokers. Conclusion: Therefore, in order to reduce musculoskeletal diseases in adults, other various factors should be looked into, and public education about appropriate posture and exercise should be carried out in community. Additionally, concentrated intervention programs for patients with musculoskeletal diseases should be performed.
