Purpose: This study aimed to verify the effectiveness of suicide prevention education using the "Life Charger" program for older adults. Methods: This study conducted the "Life Charger"suicide prevention education with 95 older adults in the experimental group. Participants were recruited from a senior welfare center and a senior citizen center in D metropolitan city, and their attitudes toward suicide and sense of competence in providing help before and after the education were investigated. While no measures were taken for the control group, their attitudes toward suicide and help-giving competence were surveyed during the same period. Statistics were analyzed using SPSS 23.0, demographic variables of the experimental and control groups were calculated as percentiles, and Chi-square analysis and paired-sample t-test were performed to verify the homogeneity of the experimental and control groups. Results: To verify the effectiveness of the "Life Charger"suicide prevention education, the effectiveness of attitude toward suicide before and after the education was verified. The experimental group showed a significantly higher level (t=-6.34, p<.000). Their competence in providing help was also at a significantly higher level (t=-10.20, p<.000). Upon verifying the effectiveness of the program, the experimental group's attitude toward suicide was found to be significantly higher; however, the control group showed no change in attitude toward suicide and competence in providing help. Conclusion: This study verified that the "Life Charger"suicide prevention education for older adults was effective in increasing attitudes toward suicide and sense of competence in providing help. To increase the effectiveness of suicide prevention education for older adults, follow-up research should determine whether there are any actual changes after the training, and attitudes toward suicide and help-providing competence should be increase d through universal and repetitive education to prevent suicide among older adults.

Ceramic plates containing many micro-holes are used in diverse applications such as MCP (Microchannel Plate). catalytic converters, filters, electrical insulators in integrated circuits, and so on. One of the efficient methods for machining many holes in ceramic plates is wet drilling of ceramic green bodies followed by sintering them. Since the strength of ceramic green bodies is much lower than the strength of sintered ceramic plate, ceramic green bodies can be drilled with high feed rate. The axial force during micro-drilling of ceramic green bodies increases rapidly at high feed rate, which induces the crack in workpiece. Therefore, the tool lift of micro-drill with respect to feed rate may be determined by the predicting increase of axial force. In this work, the axial force during micro-drilling was calculated using the chip flow model on the micro-drill tip. from which the tool life of diamond abrasive micro-drill during micro-drilling of ceramic green bodies was calculated.

Increasing demand for large-sized Floating, Storage and Regasification Units (FSRUs) for oil and gas industries led to the development of novel geometric form of Buoyant Leg Storage and Regasification Platform (BLSRP). Six buoyant legs support the deck and are placed symmetric with respect to wave direction. Circular deck is connected to buoyant legs using hinged joints, which restrain transfer of rotation from the legs to deck and vice-versa. Buoyant legs are connected to seabed using taut-moored system with high initial pretension, enabling rigid body motion in vertical plane. Encountered environmental loads induce dynamic tether tension variations, which in turn affect stability of the platform. Postulated failure cases, created by placing eccentric loads at different locations resulted in dynamic tether tension variation; chaotic nature of tension variation is also observed in few cases. A detailed numerical analysis is carried out for BLSRP using Mathieu equation of stability. Increase in the magnitude of eccentric load and its position influences fatigue life of tethers significantly. Fatigue life decreases with the increase in the amplitude of tension variation in tethers. Very low fatigue life of tethers under Mathieu instability proves the severity of instability.

Wordsworth is a poet who thought seriously about problems of human's relation to the world as perceiving subjects. What he calls "the life of things" illustrates the enabling power of things and their vitalities at play in excess of human elements. Drawing on this, he provides insights into vital materialities that act upon, and are acted upon by, the collaborative circulation between human and nonhuman agency. This paper aims to reinvigorate the debate about Wordsworth's ethics of things in terms of such critical notions as things, objects, agency, and nonhumans in an attempt to explain what he envisions as new environmental realities built upon nonhierarchical, collaborative relationships between all participants. From the vantage point of things, we see clearly what has been neglected in the New Historicist critical method. It holds fast to the conceit that humans are entitled to have sole agential legitimacy, disregarding the vibrancy of things. They opt for the objectified matter or the (re)presented state of things. But in terms of Wordsworth's life of things, all participants have equal amounts of agency regardless of their forms and for that reason humans are expected to respect other things' sovereignty. Through encounters with things, things in their thingness show up for us, only to reveal the ineradicable rupture between themselves and their objectified forms.

Purpose: The purpose of this study was to collect basic data in the quality of life related to health in migrant workers. Methods: Data from 133 migrant workers was collected from August to December 2007 using a questionnaire from two free clinics located in Seoul and Gyeonggi-do. The data was scored by mean and standard deviation. Differences were evaluated according to the subjects' general characteristics by the t-test and the ANOVA test. The relationships in the quality of life related to health between the 9 sub-scales were evaluated by the Pearson's correlation coefficient. Results: 1) Total average score of migrant workers' quality of life related to overall health is $61.09{\pm}13.68$. The score of the quality of life related to physical health is $64.39{\pm}15.21$ and the quality of life related to mental health is $57.80{\pm}16.18$. 2) With respect to the general characteristics of subjects, the quality of life related to health was significantly different in age(F=3.852, p=.013), especially in physical health(F=6.868, p=.000). 3) The relationship between physical health and mental health was significant(r=.663, p=.000). Conclusion: Program development to improve quality of life related to health for migrant workers is needed.

This study analyzed the work and retirement behavior of middle- and old-aged Koreans using panel-data based multi-state life table models. Compared to previous studies that have mainly focused on gender differences in the work and retirement behavior, this study also analyzed educational differences in the retirement life course. With respect to the heterogeneity of work and retirement experiences, this study finds that the retirement life course of men and women differs substantially. Despite their longer life spans, women are expected to have shorter working life expectancies but live in a non-working state longer, resulting in a substantially higher proportion of non-working state in their lives. In terms of educational differences, this study finds that there is little difference in the expected length of stay in the labor force across educational levels but that poorly educated persons are more likely to spend a greater proportion of their lives in the labor force due to their shorter non-working life expectancies.

The purpose of this paper is to explore the meaning of theoretical ethics regarding bioethics. First, I explore the meanings and limitations of the bioethics domain for 'the principle of equal consideration of interests' and the 'preference utilitarianism' concepts Singer presents. Secondly, I emphasize the significance of Kant's ethics in the domain of bioethics. Lastly, I suggest that Aristotle's virtue ethics should be realized in the domain of bioethics. Furthermore, I would like to suggest the meaning of human life through this. Singer's argument brings up a new topic about the meaning of evolved life not considered in the history of traditional ethics. He presented undeniable opinions about human dignity that he took for granted. In addition, it is assessed that the scope extension for the life respect target has been reasonably achieved. Contrary to this, Kant's ethics explains the meaning of human dignity based on its metaphysical meaning. Furthermore, it provides an appropriate orientation for human life. Embracing their claims is not sufficient to explain the meaning of Good Life. The meaning of Good Life is likely to be resolved through the application of Aristotle's virtue ethics. The meaning of a being of substance is living and furthermore, it is inherent to being itself.

Tornadoes are one of the world's deadliest natural phenomena. They are characterized by short life span and danger. It has been observed through post-damage surveys that localities with large numbers of buildings suffer major damage during a tornado attack resulting in huge loss of life and property. Thus,it is important to study interfering buildings exposed to tornado-like vortices. The present study focuses on external and internal pressures developed on building models exposed to translating tornado-like vortices in the presence of an interfering building model. The effects of translating speed and swirl ratio of a tornado-like vortex on external and internal pressures for a principal building in the vicinity of an interfering building are investigated. Results indicate that external and internal pressures are enhanced or reduced depending on the location of the interfering building with respect to the principal building.

This paper describes the development of a hand module of NREX (National Rehabilitation Center Robotic Exoskeleton) designed to assist individuals with sustained neurological impairments such as stroke and spinal cord injuries. To construct a simple and lightweight hand module, the robotic hand adopts a mechanism driven by a motor and moved by two four-bar linkages. The motor facilitates the flexion-extension movements of the thumb and the other four fingers simultaneously. Thus, an individual using the robotic hand module can effectively grip and release objects related to daily life activities. The robotic hand module has been designed to cover the range of motion with respect to its link distance. This hand module can be used in therapeutic rehabilitation as well as for daily life assistance. In addition, this hand module can either be mounted on an NREX or used as a standalone module.
