This paper draws some implications from Logarithmic Mean Weight Divisia Method (LMWDM) on the sources of $CO_2$ emission changes in the manufacturing sectors of Korea, UK, and USA. The sources of change in industrial $CO_2$ emission of a country, as manifested by production scale factor, structural factor, and technical factor, summarizes the forces behind the change in $CO_2$ emissions in each country's manufacturing sector. There are three observations. First one is that Korea's emission is increasing while USA and UK are experiencing reduction or stabilization of $CO_2$ emission in the manufacturing sector. Second implication is that the technical factor affecting $CO_2$ emission in Korea does not help much, or even hinder, the reduction of $CO_2$ emissions, comparing to USA and UK. Third one, which is the combined result of the first and the second one, is that Korea's increasing trend in aggregate $CO_2$ emission throughout the periods in consideration is mainly due to the failure in technical progress, or the deterioration in the structure of within subcategories, or both. The policy implications is clear. The obvious prescription is to launch a nation-wide policy drive which can revert these adverse trends.

Due to cheap electricity tariff on agricultural use, electricity consumption in agricultural sector has grown dramatically. We evaluated the negative effects of the cheap electricity tariff such as electricity over-consumption, increased dependency on electricity, decreased electricity productivity, and unequal distribution of the benefit. We also estimated the effects of agricultral output growth, structural change, and electricity intensity change on sharp electricity consumption increase in agricultural sector between 1998 and 2016 using the Log Mean Divisia Index decomposition method. The findings reinforce the necessity of raising the electricity tariff for agricultural use.

So far, the phenomenon of "electrification" has been deepened in Korean industry and especially direct heating energy which accounted for 44.0%(2010) of total energy consumed in Korean manufacturing has been significantly electrified. This paper decomposed electricity consumption for direct heating in Korean manufacturing from 1992 to 2012 using LMDI(Log Mean Divisia Index). This paper includes 4 different factors such as electricity proportion effect, direct heating proportion effect, energy intensity effect and added value effect. And this paper compared the consumption pattern by business type. As results, electricity proportion effect had contributed the most to the increase of electricity consumption for direct heating in Korean manufacturing. And Petrol-Chemical and Iron & Steel had the most electrification of direct heating.

Recently, various navigational instruments are being composed into a total navigational system. This system requires accurate ship's heading in digital form. The authors have been studying about an electromagnetic compass with a three - axis magnetic sensor in order to provide an accurate ship's magnetic heading which the compass deviations can automatically compensated in the compass itself. In this pater describe on the theory how to derive the poisson's coefficients from ship's magnetism measured with three axis magnetic sensor and the results obtained by the simulation using deviascope, and that results practically coincident with the value observed by bearing on a distant object with magnetic compass.

This paper investigates how interfuel substitution affects carbon dioxide (CO₂) emissions with a focus on the use of biodiesel blended fuels. The results show that the Divisia elasticity of diesel demand is the greatest because the transportation sector relies heavily on diesel. Also, while the own-price elasticity of each fuel demand is negative, the results reveal that diesel demand is more inelastic than the demand for gasoline and LPG. Moreover, gasoline is a substitute for diesel and electricity, and diesel is a substitute for LPG and a complement for electricity. Regarding the effects on carbon dioxide emissions, this paper computes the potential CO₂ emissions associated with interfuel substitution using the coefficients of CO₂ emissions. The results show that using biodiesel blended fuels contributes to reducing CO₂ emissions, but it appears that the price-induced interfuel substitution is a main factor affecting CO₂ emissions.

This study addresses the issue of which factors make domestic works have turnover intention. To pursue this research issue, we utilized a public database "2017 Occupational Migration Path Survey", administerd by Korea Employment Information Service (KEIS). Decision tree method was applied to extract crucial factors influencing workers' turnover intention. They include 'the degree of matching the level of education with the level of work', 'the possibility of individual development', 'the job-related education and training', 'the promotion system', 'wage and income', 'social reputation for work' and 'the stability of employment'.

Objective : The purpose of this article is to study the effectiveness of a group occupational therapy for children via systematic review, and to provide clinical evidences. Methods : The systematic review initially included articles in Pubmed, Ovid, RISS, KISS, and DBpia, published until 2014. Total 14 articles have been chosen, using different keyword of each domestic/foreign studies. Selected articles were divided depending on the level of evidence, and eventually been organized into group PICO (Patient, Intervention, Comparison, Outcome). Results : The results indicated that there are more diagnosed children than normal in participants and especially children with sensory integration disorder (28.6%) appeared to be the most common. In intervention, group sensory integrative intervention had the largest frequency, and instruments measuring social skills were used most for analyzing the intervention results. The effectiveness of interventions showing statistically significant results were 40.7% of Total. Conclusion : Group occupational therapy for children should be provided to various diagnosis with widely better quality of interventions providing the enough support for the evidence level.

Purpose: Dignity therapy is a very effective intervention to improve the dignity of end-stage patients. A concept analysis by Walker and Avant (2005) was adopted to define, describe, and delimitate the concept of dignity therapy. Methods: Nursing literature in the National Digital Science Links (NDSL) and Medline database were searched for the definitions of "dignity" and "dignity therapy". Definitions, uses, and defining attributes of dignity therapy were identified; model and contrary cases were developed; and antecedents, consequences, and empirical references were determined. Results: Through dignity therapy patients and their families share their stories, and that in turn improves the quality of life and death. Five attributes were identified: higher quality of life and death, therapeutic conversation, respect of human dignity and worth, expressing thoughts about life and death and systematic process. Conclusion: Patients at the end of their lives feel more comfortable about death. Hospice care providers should try to protect dignity of patients in their care. The attributes of the dignity therapy clarified in this study should be applied for terminally ill patients to improve their quality of life and death.

Objective : The purpose of this study is to summarize the best-available intervention evidence for children's sensory integration therapy, drawn from studies published domestically in Korea over the last 10 years. Methods : The articles evaluated in this study were collected from the RISS and DBpia databases using the search terms "sensory integration," "sensory processing," and "Ayres Sensory Integration (ASI)". A total of 19 papers were analyzed. The selected studies were then assessed using the Population, Intervention, Outcomes, and Comparison method, the International Classification of Functioning, Disability and Health (ICF) method, and the modified Evidence Alert Traffic Light Grading System. Results : Development delay was the most commonly applied diagnosis for children's sensory integration therapy and individual sensory integration therapy was the most frequently used intervention method. The intervention effect was 91 percent in the body structure and function of ICF. The areas concentrated on were sensory modulation, sensory processing, fine and gross motor, body scheme, body-self concept, balance, basic movement, postural control and hand function, attention, and self-esteem. Conclusion : This simple overview of the efficacy of children's sensory integration therapy provides a basis for easy understanding and use by therapists, researchers and families with children.
