This study was carried out in order to seek social support direction by allowing them to recognize necessity of preparing for their stably old age life and by inquiring into the preparation for old age life targeting dental hygienists who work at dental clinics. It sent questionnaire by post to dental hygienists of 1,560 dental clinics, which were sampled with a stratified sampling method, and then conducted a cross-sectional study based on self-administration. As a result of a problem of being worried in old age life, the ratio with the response as saying of being 'economy' was indicated to be the highest. The ratio of financial preparation for old age was shown to be high with 84.3%. Its method was the highest in 'fixed deposit and installment savings' with 62.6%. The satisfaction with financial preparation for old age stood at averagely 2.60, thereby having shown to be dissatisfied. It was shown to be low with 2.97 in the mean score of physical preparation for old age life, 3.59 in emotional preparation, and 2.56 in preparation for leisure. In conclusion, the satisfaction with financial preparation for old age life in our country's dental hygienists was low. Even the physical, emotional, and leisure-based preparations were shown to be low. Hence, it is considered to be likely needed to be planned preparation for old age life from the 30s. Also, for this, Korean Dental Hygienists Association needs to positively develop several kinds of programs such as education, policy and system for old age life following these people's retirement.

The number of tunnels are in fact increasing as a part of linear improvement project of general national highway and road enlargement and pavement project. Recently, collapses of portal slope are also occurring considerably, due to local raining from severe rain storm and abnormal weather. Accordingly, it was risen a necessity to efficiently respond to tunnel portal slope damage and maintenance in Korea and oversea nations. This paper is a basic proposal to execute a survey on the current status and state of the tunnel portal slopes that were already installed and are now being operated along general national highways, and also to execute state evaluation for the purpose of managing those effectively. As a research method, domestic tunnels were analyzed in accordance with geometrical shape such as access type, portal form, and tunnel type, etc. via field survey to analyze the types of tunnel portal slopes along national highways. State evaluation classification sheet is presented to divide classes for the danger state of the surveyed portal slopes, and then the related grades are divided. It is mainly aimed at classifying the tunnel portal slope along national highways with using this state evaluation, to use it as basic data so that continuous maintenance can be executed in the future in accordance with danger classes.
In an effort to resolve the burden of patients hiring patient sitters, this study sought to review the Ministry-of-Health-and-Welfare-initiated pilot program of running hospitals without patient-sitter to identify its background, operation method, performance results, and limitations. Based on the review, the study derived the necessity of introducing a hospital system without patient-sitter as well as its operation and systemization methods. The ministry-initiated pilot programs were conducted twice: in 2007, and in 2010. A review of the 2007 pilot program revealed that the patients and families' satisfaction score with nursing services was 9.1 points (on a 10-point scale), their intention to reuse the service was 97.8%, and their intention to recommend the service was 98.0%, all high scores. Appropriate nursing manpower, derived from the 2007 pilot project, indicated 2.3 patients per nurse and 4.0 patients per nurse aid. The 2010 pilot project results indicated that the patients and families' satisfaction was high at 8.0-9.1 points (on a 10-point scale), and that the intention to reuse and recommend the service was also high. Compared with the 2007 pilot project, however, the types of medical institutions and the nurse to patient ratios were diverse, offering limitations. In conclusion, to systemize hospitals without patient-sitter, it is necessary to develop policies designed to establish criteria for the appropriate nurse to patient ratio and skill-mix, to standardize the work, to prepare finances for securing nursing staff, to evaluate the nursing demands, and to monitor the quality management.

Recently, it was emerged to need the necessity of LPG residues management due to the finding some substances such as rust. This study is performed to investigate the characteristics of LPG residues in the production and distribution stage of LPG. For the qualitative analysis of LPG residues, it was operated to be set up the analysis conditions(the flow rate, etc) of GC-MS and was performed to analyze the component of LPG residues. From the analysis result using GC-MS, it was shown that the component of LPG residues was turned out the plasticizer to be used in the rubber manufacturing process. The inorganic components of LPG residues were analyzed using ICP-OES. At the results of inorganic analysis, it was shown that the Si element was detected, which was presumably derived from defoamers used mainly in the LPG production. Also, the P and Zn element, which are estimated to be components of grease additives used for filling facilities, were also partially detected. No trace of rusting was detected in the LPG residues in the production and distribution stages analyzed in this study. But, as plasticizers and grease additives can affect to the LPG fuel system in vehicles, it will be necessary to use the proper quality of rubber and to expand the use of low boiling grease additives.

Smart TV sareequipped with an operating system and combined with internet functionality. They can use various apps and contents, and provide personalized and interactive services. However, the Internet connectivity of smart TVs has several security vulnerabilities that can cause significant personal and social harm. Therefore, it is necessary to develop a smart TV with a higher level of security than is currently available. In this study, we analyze consumers' purchase intention for smart TVs with security reinforcement by applying the UTAUT2 model. The results are as follows. Firstly, it was found that performance expectancy, social influence, facilitating conditions and price value, as important variables under the existing UTAUT2 model, have significant effects on purchase intention. Secondly, effort expectancy did not have a positive impact on purchase intention. Thirdly, there was a moderating effect of gender on social influence. According to the results of this study, social influence has the most powerful effect on the purchase intention of smart TVs with security reinforcement. Therefore, in order to improve the purchase intention of smart TVs, it is necessary to expand the publicity activities designed to promote the necessity and importance of reinforcing the security of smart TVs and make them easier to use.

Even though software (SW) education has not been considered part of the current national kindergarten curriculum, in practice there is growing interest in adopting it. Teachers would be expected to play a key role in the successful introduction and implementation of new educational changes, such as SW education. In preparation for its adoption in ECE, it would be useful to determine ECE teachers' perception and attitudes toward early childhood software education. For this study, 219 ECE teachers' level of concern toward SW education was surveyed using the Stages of Concern Questionnaire. It was found that the teachers' level of concern was the highest at stage 0-Unconcerned and that they had high levels of stage management, personal and informational concern. Thus, a non-user pattern was mostly indicated. However, compared to the typical non-user pattern, the pattern aspect close to critical non-user ever appeared to some extent. In addition, a significant difference in the level of concern was shown at all stages depending on the awareness of the necessity for SW education. The teachers with SW training experience showed a higher intensity only at stage 0. There was a statistically significant difference in stages 0 and 6 depending on the future implementation decision. These results will be utilized as a resource in building an ECE teachers' support system according to their level of concern about SW education.
The optotypes widely used as a necessity in the course of optometry are the world authorized versions which contain items such as the Landolt's rings, Snellen's chart and also Arabian numbers, Korean letters, Pictures and so on. In Korea, the Hahn-chun-suk test chart has been In use generally alolng with Chung-san test chart and Jin-yong-han test chart also in use on the wall. But these sort of test charts hung on the wall have some problems such as the difference in test results owing to the rate of illumination and so a more accurate method is required. To solve the problem of inaccuracy in optometry, the projected type of charts with digital instrument such as the beam projector has been developed lately. This chart projector with consistent high resolution and the ability to provide various charts can help eye examiner perform effective examination and thus is looked positively upon as the automated total optometry system. So in this study our purpose is to examine the accuracy of the projected chart. It was done by comparing it with the frequently used test chart. The results of experiment are as follow. When the projected chart was used, cases that subject read charts one step higher were 10%, two step higher 2% than perfectly corrected vision. When Han-chun-suk test chart was used, cases that subject read charts one step higher were 12%, and two step higher were 4%.
The technical regulation and conformity assessment procedure of our country on ICT equipments is currently required to have more innovation due to the request of main trade countries, the second phase conclusion of MRA, necessity of expansion of conformity assessment service market and demand of manufacturers. The world's leading advanced countries have already proceeded with innovation based on privatization plan. According to the comparative analysis of the level, it turned out that Japan obtained the highest level of privatization while South Korea ranked the lowest level. According to the research result of examination and certification ability of private institutions of our country, it turned out that our country is expected to have possibility of achieving higher level of privatization than that of the present. Moreover, according to the questionnaire survey conducted to the persons concerned regarding privatization direction, they gave positive response to all the indicated survey contents of privatization direction in terms of "delegation of certification services to private sectors (contracting-out)", "transformation of EMC into private voluntary standard" and "changeover of conformity assessment agent". However, from the view of acceptance and conflict model, it is estimated that starting from "delegation of certification services to private sectors (contracting-out)" seems to be the most advisable plan. Also, prior to privatization, it is required to improve relevant systems such as certification examiner system.
The development of ICT brings a big change in manufacturing industries, and new information technology such as IoT, AR, and big data was applied on manufacturing process. As a result, the concept of smart factory has been introduced as a new manufacturing paradigm. In fact advanced countries like USA, Germany, and Japan have actively introduced smart factory in their manufacturing industries such as electronic, automobile, machinery, to improve production efficiency and quality. The manufacturing environment has been changed into flexible system, so that smart factory will be leading future manufacturing industries. Thes changes have more severe influence on Korean manufacturing industries. Mny industrial companies, have a strong interest in smart factory and they, particularly big enterprises, have been adopting smart factory to increase their manufacturing efficiencies. However, Korean small and medium-sized enterprises (SMEs) have many financial and technological difficulties so that the diffusion of smart factory in Korean SMEs has not been satisfiable up to present. However, smart factory is very important for enhancing their competitiveness in global market. Therefore, this study aims at identifying the standardization strategy of smart factory in so-called Korean 'roots industry' by presuming that the standardization will activate the diffusion of smart factory among Korean SMEs. For this purpose, first, this study examines the competitiveness of SMEs, especially in 'roots industry' and identifies the necessity of diffusion of smart factory among those SMEs. Second, based on the active review on the existing literature, this study identifies four factor groups that would influence the adoption or diffusion of standardized smart factory. They are technological, organizational, industrial and policy factors. Third, using those four factors, this study made two comprehensive case analyses on the adoption and diffusion of smart factory. These two companies belong to molding sector which is one of the important six sectors in 'root industry'. Finally, based on the theoretical and empirical analyse, this study suggests four strategies for activating the standardization of smart factory; international standardization, government-leading standardization, firm-leading standardization, and non-standardization.

To be applicable under electronic health record system in order to ensure semantic interoperability of clinical information, the development principle for clinical information model to reflect objective and function is required. The aim of this study is to develop the development principles for clinical information model and evaluate the Clinical Contents Model. In order to develop the principle, from November 2008 to March 2009, the surveys about 1) definition, 2) function and 3) quality criteria were done, and 4) the components of advanced model were analyzed. The study was processed in 3 levels. Firstly in the development level, key words and key words-paragraph were driven from the references, and the principles were drawn based on the clinical or functional importance and frequency. In the application level, the 3 experts of clinical information model assessed 30 Clinical Contents Models by applying it. In the feedback level, the Clinical Contents Model in which errors were found was modified. As the results, 18 development principles were derived with 3 categories which were structure, process and contents. The Clinical Contents Models were assessed with the principles, and the 17 models were found that they did not follow it. During the feedback process, the necessity of the advanced education of the principle and the establishment of the regular quality improvement strategy to use it is raised. The proposed development principle supports the consistent model-development between clinical information model developers, and could be used as evaluation criteria.
