This paper applied the Blue Print and FMEA (Failure Mode and Effect Analysis) to education service in order to raise the education service satisfaction. First, the Blue Print is deployed to come up with strategies to overcome the fail possibility point and waiting point. Next, in order to analyze the fail factors and alternative strategies, the Blue Print of education service is applied to FMEA. The results are as follows; first, the ommission from information document by web-mail or e-mail, Second, thing that selected in spite of company uneducated, thing that omitted despite the company is target, and the unsatisfaction of attendee about training contents. Third, the delay of counsel at the telephone reply, erroneous list of course name and attendee at HRD (Human Resource Development), omission of check whether attends or not. Except for unsatisfaction of attendee, all appears at the process that service delivered. And the unsatisfaction of attendee is about education contents. Both is the factor which have influence on the education service quality. The strategies to remove the failure mode are training and manual development on service and work, a thorough management and check of information system like as ERP (Enterprise Resoure Planning), HRD, education institution list DB (Data Base), on-line application system, a development of education program to offer best education that reflect the user needs and continuously changing environment.

Purpose: This study was carried out to investigate the difference in job satisfaction and marital satisfaction by gender and to explore the influences of demographic status. employment characteristics. and job satisfaction/marital satisfaction on each type of satisfaction. Method: Social statistics survey data collected by National Statistical Office in 1998 were used for the secondary analysis in the study. Job satisfaction was measured by questionnaires, which consisted of 12 items such as task, promotion, placement, wage, benefits, future in the work, working environment, human relationship. and working hours. And marital satisfaction was collected by questionnaires which consisted of 7 items, including satisfaction with general family life, relationship with their own parent and parent-in-law, relationship with brothers and sisters, relationship with their children, and economic living status. These are measured by 5-point Likert scale. Result: The results show that more than 60% of women were working as part-time employees. Their education levels were lower than men. Men were satisfied significantly more in their jobs than women. Men also had higher marital satisfaction. The employment status had the most important factor on the job satisfaction. and the marital satisfaction was the second important factor among women and men. As for the age, while older men showed higher job satisfaction, younger women showed higher job satisfaction, 28.04% of the variance in the job satisfaction for men and 33.86% for women were accounted for by the following variables: the younger age. the higher education. job satisfaction, and the higher marital satisfaction, 22.15% of the variance in the marital satisfaction for men and 21.19% for women were accounted for by these variables. Conclusion: The results of this study showed that there were differences in job satisfaction and marital satisfaction between genders, and that job satisfaction and marital satisfaction influenced each other. Employment status was the most predictive factor on the job satisfaction. Married women had an unstable employment status such as part-time position. The stability of employment could be considered as a strategy for enhancing job satisfaction for both sexes. The reason that women had lower marital satisfaction than men will have to be further investigated.

The study of Arundinaria munsuensis Y. Lee to this day was limited to the field of morphological species classification since its first discovery at Jiri mountain in the late 1990s. This native plants, one of Korean endemic species found in Jiri Mt. necessitates further studies about its use as revegetation plants or groundcover plants in urban areas. This study was launched from this need followed by summaries of results below related to its usage. This targeted species is a native Korean species which its natural distribution on the subalpine zone has merit for the wide range of climatic adaptation. Also, the coverage rate reached 78.3% in three years mostly by rhizome growth with an expectation of full coverage in four years providing less maintenance needs after planting. The net price for the construction of pot seedling methods of this plants is relatively economical than other normal revegetation construction methods. For these reasons, drilling for the plants on cut and fill soil slopes driven from pot seedling adapts Arundinaria munsuensis Y. Lee as efficient revegetation plant. Total construction cost for pot seedling work($30cm{\times}30cm$) of Arundinaria munsuensis was approximately 21,000won which is in reasonable price range when compared to other revegetation construction methods of disturbed slopes. As a native Korean plant, Arundinaria munsuensis has wide range of climatic adaptation with less maintenance requirement after planting. This study may suggest a strong possibility of Arundinaria munsuensis as a pot planting material in sloped area.

Perfluorinated Compounds (PFCs) are anthropogenic compounds found in trace amounts in many environmental compartments far from areas of production. Along with the highly persistent nature of PFCs, there are increasing concerns over the potential adverse effects of them on the ecosystems. Most of highly fluorinated compounds degrade into PFOS and PFOA that are very stable compounds hard to break down. So, in this study, we tried to determine the toxicity of PFOS and PFOA in the terrestrial invertebrate. Acute toxicity test using earthworm, Eisenia fetida, was performed according to the OECD test guideline 207 (Earthworm, Acute Toxicity Tests). In the 14 day acute toxicity tests, the highest concentration causing no mortality and the lowest concentration causing 100% mortality of PFOS were 160 and 655 mg/kg (dry weight), respectively. And the highest concentration causing no mortality and the lowest concentration causing 100% mortality were 500 and 1,690 mg/kg (dry weight), respectively in the PFOA-exposure group. 14 day-LC50 values were estimated at the level of 365 and 1,000 mg/kg (dry weight) in the PFOS and PFOA-exposed group. These results indicate that under laboratory conditions PFOS is about 3 times more toxic to earthworms than PFOA. Based on known environmental concentrations of PFOS in the soil of Korea, which occur in the 0.42~0.73 ng/L range, there is no apparent risk to terrestrial invertebrate, earthworms. However, further work is required to investigate long-term effects on these and other terrestrial organisms.

The purpose of this study is to analyze the influence of attitude of mothers on the dental health and behavior of dental health management on children on the dental caries of their children, and the questionnaire survey was implemented and analyzed for 202 children in fifth and sixth grades of two elementary schools in Ulsan City along with their mothers with the following outcome. 1. 80 students from entire subject students(39.6%) are subjects of dental caries with the average DT index shown to be $1.78{\pm}1.04$ and tended to have higher in the upper level of grade. 2. In the attitude of dental health management for mother, 95 students(47.0%) visited the dental clinic within 6 months with the main purpose of treatment, rather than preventive work, for 141 students(69.8%), and hey have high level of interests on the teeth condition of their children but they rarely take a close look at the dental condition for their children. 3. The efforts of mothers on preventing the dental caries by mothers showed in the sequence of regular instructions for brushing, limiting the sugar intake, fluorine coating, sealant, regular examination and the like and DT rate will be decreased by these kinds(p<0.05). 4. The number of dental caries of children with the attitude of mother in dental health showed noticeable differences statistically with respect to the brushing method, use of dental sanitation goods, scaling, visit to dental office and others(p<0.05). With the above conclusion, the attitude and behavior of mothers on dental care influences greatly on the dental health of children. Therefore, in order to improve the dental health of children, it would be important to recognize the importance of attitude and behavior of dental health for mothers for positive dental care with the support in policies.

This work aims to introduce the concept of microcomputer aided port design simulation methodology including the analysis of the mathematical models to be implemented and apply it to the Third Stage Busan Part Development Project. In the Busan case study the size of the proposed turning basin of the new terminal together with the operational stra-tegies of berthing and unberthing was examined In addition the safety of ships' entry and exit through the projection new breakwaters was as-certained. From the application of simulation to the Busan project it was found that the proposed dredging area was not sufficiently wide enough for a modelled container ship to perform A type unberthing (in which the ship turns to port as she monoeuvres away from No.1 berth with the ass-istance of tuges) especially in a strong easterly wind., It is therefore recommended that Busan pilots should be advised to use B type unberthing strategy in which the ship goes astern from No.1 berth to the turning area in front of No.2 berth(where the ship turns 180 degrees clockwise) especially when the wind is very strong. It is also recommended that a sea buoy be placed outside the new breakwaters as this was found to im-prove the safety of ship manoeuvres through the breakwaters significant-ly. Another recommendation is that the Korean Hydrodynamic Office carry out a detailed survey of the currents in the water area near the new breakwaters. once they have been constructed. In addition it is to be recommended that a current meter be placed at the recommended sea buoy pardised by erroneous current information

중소규모 설계사무소에서의 BIM(Building Information Modeling) 활용은 BIM 라이브러리 및 기술콘텐츠 등 요소 기술의 부재로 인하여 아직까지도 미흡한 실정에 놓여있다. BIM을 도입하고 활용하는 설계사무소의 기술적인 부담을 최소화하기 위해서는 BIM 라이브러리 및 기술 콘텐츠를 제공하고, 단일 BIM 정보를 다양한 용도로 공유 및 교환하는 체계가 필요하다. 왜냐하면 BIM 설계는 단순히 3D 형태로 건물의 외관만을 설계하는 것이 아니라 공사에 들어가는 물량을 산출하고, 자재 정보 등을 바탕으로 기술에 관한 설계정보 등을 제공할 수 있어야 하기 때문에 기술 콘텐츠의 마련이 필수적이라고 할 수 있다. 따라서 본 연구는 설계 업무 단계에서 BIM 데이터와 기술 콘텐츠가 연계 사용될 수 있도록 시스템 모듈 개발을 통해 BIM 기술 콘텐츠를 보급함으로써 BIM 기반 설계 업무의 효율성을 높이는 데에 목적이 있으며, 개발된 BIM 기술 콘텐츠 데이터 활용 시스템 모듈을 통하여 BIM 저변이 확대될 수 있는 근간을 마련하고자 한다.

Using low outdoor temperature, free cooling system is used in a data center or industrial air-conditioning for energy saving. Because use of IT equipment has increased in some office building recently, there is a growing trend towards using free cooing system. Free cooling system performance is influenced by outdoor temperature. Therefore the performance is different with regions. In this study, performance characteristic of free cooling system is analysed and energy reduction is compared with some regions. Selected regions are 4 cities; including Ulsan analyzed in preceding research, Seoul, ChunCheon and Daejeon. The Aspentech software HYSYS 8.0v was used to conduct the analysis of free cooling system based on temperature per hour of 4 cities in 2013, respectively. The main result is following as. Free cooing system in this study has energy saving effect when outdoor temperature below $7^{\circ}C$. Becuase temperature of Chuncheon is relatively low, using free cooling system can conserve most air-conditioning energy. Energy reduction amount of Seoul is 11%, Chuncheon is 17.5%, Deajeon is 15%, Ulsan is 14%. In case of large scale of air-conditioning, it is reasonable to use free cooling system although the system is used in Seoul.
