The design, construction and management of underground facilities as infrastructure of nation should be properly carried out. One of reasons for underground facilitie's failure is a non-proper construction of backfill materials. This is common for circular underground pipes. A non-proper compaction is the cause of settlement and decrease of performance of underground facilities. The use of controlled low strength materials is an alternative to reduce the couple of failure problems. The flowability, self-cementation, and non-compaction are the major advantages to use the controlled low strength materials. In this research, couple of recycled materials, such as in-situ soil, water-treatment sludge, and crumb rubbers, were adopted. The basic properties of each materials were determined according to KS or ASTM. Also, couple of laboratory tests were carried out to get the design parameters for geotechnical and roadway area.

The study participants were 15 students in the 4th grade of the department of nursing, and data were collected through in-depth interviews. The results of analysis resulted in four themes: 'motivation of learning', 'self-directed learning', 'improving achievement', and 'insufficient learning requirements'. The core fundamental nursing skills applying reciprocal peer tutoring has a positive experience of inducing motivation of learning for participants through a comfortable environment and improving self-confidence, and gaining opportunities to lead prior learning and learn in the learner's language. However, there have been experiences where additional knowledge expansion is difficult and feelings of insecurity is felt due to insufficient learning requirements. Therefore, when applying the reciprocal peer tutoring method to self-directed practice, it is considered to be effective if the professor applies a method that can sufficiently satisfy the learner's learning needs.

This study aimed to examine the personality traits of a specific group using color reflection reading (CRR) analysis. An experiment was conducted to examine the color preferences of dental hygienists in a certain community. The color psychology test was conducted with 238 dental hygienists currently employed in dental clinics or hospitals in Gwangju, Jeollanam-do, in the form of a self-administered questionnaire. Participating dental hygienists were differentiated into groups by their order of selection of eight different colors, and the results were analyzed using SPSS 22.0. The analysis results showed that the most common first-, second-, and third-choice colors were magenta, yellow, and magenta, respectively. By age, magenta was the most common first-choice color in all age groups. When the results were analyzed by marital status and the presence or absence of offspring, the same results were obtained. Yellow and blue were the most common second-choice colors for married and unmarried participants, respectively. The findings were expected to provide data for human resource management, such as for developing better working environments that account for stress relief or psychological stability using color preferences or complementary colors.

This paper analyzes the actual 'content' and 'role' of the intrinsic motivation of creative laborers during the creative production process. Based on semi-structured intensive interviews with 16 light-entertainment television PDs in South Korea, this paper articulated that intrinsic motivation towards creative work could be understood as a desire to maintain their level of enjoyment from creative work. The desire was classified into two different types of 'enjoyment', one was the enjoyment based on the expectation regarding the creative job, and the 'enjoyment' experienced primarily related to the creative production process that allows creative workers to actualize individual creative ambitions. In addition, such intrinsic motivation tended to provide a strong driving force for creative workers as they endured unfavorable working conditions that resulted from market principles(viewership ratings), economic stability, and work-life balance. This paper proposes that the tendency of creative workers to endure various undesirable working conditions is based on a strong intrinsic motivation to maintain their level of enjoyment from their creative career.

The purpose of this study is to discern elementary students' career education model based on career anchor. For this purpose, we have researched literatures and case studies related to career anchor and developed a draft of the career education model. Afterwards, through expert formative evaluation of the draft, we have developed the final model. Specific model's processes include 'finding yourself' - 'selecting learning contents based on career anchor'- 'studying based on career'- 'over coming things lacking in your career' - 'assessment'. These steps include activity content and supporting elements for learners. This study is different from precedent career education related studies because through career anchor the learner can find his true self, teachers can able to teach flexibly while adjusting to diverse environment changes, also this program can be utilized within the class setting immediately, and it is developed to help learners and teachers to utilize the program with ease and systematically.

This study aims to spatialize the gap between obesity levels through the body mass index, an objective indicator of the level of health among vulnerable people. Thus, areas where the BMI showed cluster patterns with spatial high and low values were extracted and the characteristics of the region were analyzed. The analysis showed that the I statistics for the obesity rate were 0.07 and the z-score was 4.39, confirming spatial autocorrelation. For z-score, it was much larger than the maximum threshold of 2.57. This means that the rate of obesity among the socially vulnerable is regional, and this gap is spatially significant. The results of comparing and analyzing the local environment for these areas of obesity and health care were found to be areas with poor public transportation, less readily available parks, and a concentration of single and multi-generation housing. The analysis results of this study are meaningful in that they provide spatial implications for the health of the socially vulnerable class that previous studies have neglected.
