The purpose of this study was to explore the experience of choosing the best days for childbirth and to understand the nature and meaning of the experience. The qualitative method of data collection was used, and in-depth face-to-face interview were conducted. Participants included four women who had given the day of birth set as the desired date. Van Manen's phenomenological method was adopted to analyze data. Four theme clusters emerged from the analysis: "The first gift to my baby"; "Collaboration with others for my baby"; "Choosing a date for childbirth such as blueprint of child"; and "Complex feelings." Our findings helped in understanding the experience of Korean women in choosing the best days for childbirth. Health care providers should offer appropriate advice and show sufficient empathy as well as emotional support by considering cultural expectations.

An Analysis of the Choice of Wedding Time Based on the Gimundungap Theory. The purpose of this study is to research the utility and validity of wedding time selection based on the principles of Ungokgimun, a recent development of Gimundungap theory. Unlike the conventional way of choosing from common auspicious hours and days deemed available for important ceremonial occasions, Ungokgimun determines the propitious heavenly wedding time catered for a particular couple based on the birth table consisting of the four pillars of the bride- and groom-to-be. Using the Hong Guk-soo numbers which are drawn from the basic principles of oriental philosophy, it utilizes a deductive approach to wedding time choice, which is considered decisive and logical. Wedding time selection for a bride and a bridegroom is determined by auspicious combinations of matching and supporting HongGuk-soo numbers. Some relevant determining factors for the time choice are three number combination of samhap, two number combination of half-hap, latitudinal combination of yuk-hap, support and control relationships between related elements, two number punishment of hyung-sal, and three number punishment of samhyung-sal, etc. The specific auspicious palace of the spouse-to-be's luck is selected on the basis of supporting or brotherly combination of numbers which are manifested on the baseline earthly plate of the bride- and groom-to-be. This is followed by the selection of the ten-year luck, and year and month luck, and finally by the selection of auspicious day and hours. The validity of this study was verified through theoretical consideration of the Ungokgimun and practical analysis of a variety of marriage cases. It was found that the way of wedding time selection using Ungok Gimundungap was relatively more effective than other conventional methods.

하지 않는 것이 현실성인것 같다. 그래서 소주택을 세우는데 있어서도 외관을 살려 아름답고 훌륭한 주택을 건축하여 집 주위도 화려한 외관을 만들 수 있게 소주택의 외관 Design에 대해서 연구해 보고자 한다.

천상열차분야지도에는 유방택이 계산하여 작성한 중성기가 실려 있다. 중성기란 24절기일 각각에 대해 혼각과 효각에 자오선이위치하는 하늘의 입수도를 표로 만들어 놓은 것이다. 우리는 유방택이 사용할 수 있었던 역법이 선명력과 수시력이라고 생각하고, 우선 수시력에 의한 중성 계산법으로 을해중성기를 계산해 보았다. 이때 적도수도 값에 따라 중성기가 달라질 수 있는데, 유방택이 사용가능한 28수의 적도수도는 천상열차분야지도에 수록되어 있는 것, 수시력에서 사용한 것, 선명력에서 사용한 것이 있었을 것이다. 우리는 여기에 몇 가지 다른 적도수도들의 경우를 더하여 유방택이 어떤 계산 방법으로 중성기를 작성했는지 알아보았다. 그 결과, 베이징 기준의 수시력과 선명력의 적도수도의 조합이 을해중성기와 가장 가까운 결과를 주었으며, 천상열차분야지도의 적도수도와 수시력의 적도수도도 비교적 을해중성기에 가까운 결과를 주었다. 우리는 유방택이 선명력의 중성 계산 방법과 선명력의 적도수도를 사용하여 을해중성기를 작성한 것이 아닌가 추측하고 추후 연구를 계속하려고 한다.

"Tack" is defined as "the property that enables an adhesive to form a bond with the surface of another material upon brief contact under light pressure". The tack depends on a number of experimental parameters. We can control various experimental factors (contact force, dwell time, pretest speed) using probe tack tester. We are here concerned with pretest speed of experimental factors using SIS-based hotmelt PSA and water-borne acrylic PSA.

Spray paving minimizes material lost during the construction or repair of a road surface, and it can be done in conjunction with tack coating. This approach involves applying the asphalt mixture at the same time as spraying the tack coat by attaching a spraying device to the asphalt paver. When applying an asphalt overlay to an aged concrete surface, it is important to ensure the adhesion performance between different material properties. Accordingly, there is a need for a tack coat that can be applied by spray paving and that exhibits good adhesive performance on different materials. In this study, bonding strength tests under various conditions were performed to evaluate the basic performance of a tack coat developed for use with a spray paver. The bonding performance of the tack coat was observed to be affected by curing conditions and material lost during construction. The test results also showed that the tensile and shear bonding strengths of the developed tack coat were 1.21 and 1.99 times higher than those of a conventional one, respectively. As a result, the developed tack coat is considered suitable for application to spray paving.

Bond shear strengths of recycled asphalt concrete were evaluated under different tack coat applications. Regardless of the new and old mixtures, the bond shear strengths at $30^{\circ}C$ were increased by 10-20% than those at 1$0^{\circ}C$. The bond shear strengths of recycled asphalt concrete without tack coat showed very low ones. These are the main reasons for the frequent longitudinal interface crack in the field. The effect of tack coat curing time on bond shear strengths was inferior to the tack coat construction temperature.
