The morphological characteristics of the baculum were compared among Rhinolophus ferrumequinum, Hypsugo alaschanicus, Vespertilio sinensis, and Murina hilgendorfi. Their bacula were located at the distal end but their shapes were differed among species. V. sinensis had the longest baculum (mean=7.27 mm), followed by R. ferrumequinum (mean=5.02 mm), H. alaschanicus (mean=2.60 mm) andM. hilgendorfi (mean=2.15 mm). The baculum of R. ferrumequinum was Y-shaped, with a pointed tip and that of V. sinensis was long and conical. However, the baculum of H. alaschanicus was I-shaped, with the widths of proximal and distal ends larger than that of the shaft. The baculum ofM. hilgendorfi was small, and oval shaped. The shaft of the baculum of R. ferrumequinum and H. alaschanicus was linear in shape, whereas that of V. sinensis was curved towards the distal end, and that ofM. hilgendorfi was bent upward. The results showed that the baculum morphology differed among these four species. These findings can be utilized as an identification key for these species, and they can be used as baseline data for studying the phyletic relationships of bats.

본 연구에서는 간척지에서 플라스틱 온실의 기초안전성을 평가하기 위하여 강재 나선말뚝기초를 갖는 폭 6m 연동하우스 1개동과 강재 나선말뚝기초와 파이프줄기초를 각각 적용한 폭 8.2m 단동하우스 2개동을 SPT N값 이 2인 간척지 시험포장에 설치하여 플라스틱 온실의 인발량 및 침하량을 측정하였다. 또한 플라스틱 온실에 적용된 나선말뚝기초 3종(φ50, φ75 및 φ100)을 인근의 간척지 시험포장에 설치하여 인발저항특성을 시험하였다. 평가 기간 중 플라스틱 온실의 수직변위 움직임이 관측 되었지만 온실의 규모와 비교하여 그 변위는 무시할만한 수준이었다. 평가 기간 중의 최대 수직변위는 나선말뚝 기초를 적용한 연동하우스의 경우 +9.0mm(인발)~- 11.5mm(침하), 나선말뚝기초를 적용한 단동하우스의 경 우 +1.3mm~-7.7mm, 파이프줄기초를 적용한 단동하우스 의 경우 +0.9mm~-11.2mm로 나타났다. 나선말뚝기초의 허용인발력은 모두 극한하중 판정기준에 의해 판단할 수 있었으며 φ50mm, φ75와 φ100 나선말뚝기초의 최종 허용인발력은 각각 0.40kN, 1.0kN과 2.5kN으로 산정할 수 있었다. 평가기간 중 나선말뚝기초를 적용한 플라스틱 온실의 기초안전성을 최종적으로 판단하기에는 다소 무리가 있다고 판단되나 강재 나선말뚝기초를 간척지 플라스틱 온실의 기초로 사용하더라도 큰 문제는 없을 것으로 판단되었다.

PURPOSES :This study aims to develop a sealant for use in the installation of Weigh-In-Motion (WIM) sensor for asphalt concrete or cement concrete pavements.METHODS:In order to investigate the properties of various sealants that were mixed with latex and carbon fiber, various test methods were adopted, such as bituminous bond strength test, softening point test, and cone penetration test. To evaluate moisture susceptibility, the BBS test was conducted under moist condition. The bond strength ratio (BSR) was calculated based on tensile strength ratio method.RESULTS :The sealant’s properties significantly varied according to the amount of latex or carbon fiber. The usage of latex marginally enhanced the cone penetration test result, notwithstanding reduced asphalt content. This implies that the sealant will be proper cold temperature reason. Moreover, the addition of latex and carbon fiber evidently increased the softening point. This indicates that the tendency of the material to flow at elevated temperatures is encountered during service. With the addition of latex and carbon fiber, the moisture susceptibility measured with BSR improved marginally, while the bond strength under dry condition decreased marginally. Sealant F displays the highest bond strength and BSR under limited test conditions.CONCLUSIONS :According to the proportion of latex and carbon fiber mixed, properties of sealant, such as softening point, cone penetration, and BSR varied marginally. This indicates that the sealant has to be applied considering the environmental condition, to improve service life.

As a preparation of a design standard regarding road facilities in terms of reliability based optimum design examples, such as cantilever columns for traffic lights, optimum design in deterministic and probabilistic ways for the foundation of traffic lights poles are proposed. Most of the previous study have focused on the foundation surrounded by cohesionless soil. However, the design would be governed by risky condition. Therefore the resistance by clay-soil is investigated compared with other design specifications. In deterministic optimization, GRG method is applied. It is found that both geometries of deep and shallow foundation provides optimum values. The resistance of cohesive soil is selected to represent the ultimate limit states, in terms of sliding, overturning and bearing pressures from super structures to the foundation under external loads. Example foundations with varying height of columns for traffic lights are optimized about 30% decreased embedded depth of foundation. The optimum coefficients of resistant and load factors may need to be developed with design load combinations in order to prepare design specifications as the next step.

사회복지와 영성의 연구동향을 보면 포스트모더니즘의 영향으로 지 금까지의 학문이 과학적인 연구에 치중해 왔음을 반성하고 영성적 접근 을 통해 과학과 영성의 학문적 통합과 융섭의 필요성을 제기하고 있다. 미국에서는 1990년도에 관련학회가 생기고 영국과 캐나다, 호주 등에서 도 지속적으로 연구결과가 나오고 있지만, 한국은 2012년에 영성과 사 회복지학회가 생기고 연구도 시작단계라고 할 수 있다. 종교계에서는 가톨릭 사회복지회가 3년 전부터 가톨릭 사회복지의 실 천을 위한 영성프로그램을 개발해서, 사회복지 실천현장에 적용시키기 위한 시도를 해오고 있다. 불교계도 관심을 갖고‘불교 사회복지의 영성 적 관점’을 주제로 포럼을 개최하기도 하였지만 사회복지 실천현장에 적용하기 위한 구체적인 계획과 시도가 필요하다. 이러한 시도의 일환으로 일터영성의 연구동향을 살펴보았으며, 실증 적 조사연구를 위해 사회복지기관 종사자들의 사회복지와 영성의 인식 정도, 사회복지사의 영성과 직무만족, 사회복지기관에서의 일터영성을 조사하여, 그 내용을 종교계와 일반 사회복지기관의 종사자들을 중심으 로 비교 분석하고자 하였다. 이렇게 도출된 결과를 통해 불교 사회복지 의 영성적 실천을 위한 실증적인 조사연구의 계기가 되었으면 한다. 연 구내용은 불교 사회복지의 영성적 실천을 위한 조사연구로 조계종·가 톨릭·서울시의 사회복지기관 종사자들을 중심으로 조사를 실시하여 그 결과를 비교 분석한 것이다. 불교계의 경우 비교적 저조한 평가가 나왔는데, 이러한 분석내용을 바탕 으로 불교 사회복지의 영성적 실천을 위한 관심을 제고하고 불교 사회복지 와 영성의 개념정립, 불교계 사회복지기관 사회복지사의 영성 교육과 훈련, 불교사회복지와영성프로그램개발의필요성을제안하고자하였다.

PURPOSES : This research was a fundamental study on the application of an integral TiO2 solution to asphalt concrete pavement. The integral TiO2 solution was produced in pilot production equipment; application of the integral TiO2 solution to asphalt pavement was conducted to examine the pollution-reducing capability of photocatalytic compounds such as TiO2. The photocatalytic TiO2 reacted with air pollutants, converting them into small amounts of relatively benign molecules. METHODS : In this study, laboratory experiments were conducted using five various testing methods. Tensile strength ratio (TSR) and British pendulum test (BPT) were conducted in order to evaluate the properties of asphalt pavement subsequent to the integral TiO2 solution coating. In addition, methylene blue testing, a measurement of nitrate on the coated pavement, and nitrogen oxide (NOx) reduction testing were conducted in order to evaluate photocatalytic reaction. Lastly, a UV-A lamp was used as a light source for photocatalytic reactions. RESULTS : Test results indicated no change in the properties of asphalt pavement following the integral TiO2 solution coating. In order to evaluate the performance of asphalt pavement as a function of TiO2, the moisture susceptibility and skid resistance were investigated. The moisture susceptibility and skid resistance satisfied there quirements related to pavement quality and safety specification. Furthermore, the effects of reduction of air pollution were significantly improved as determined via the methylene blue test and NOx reduction test. The TiO2-paved asphalt specimen exhibited approximately 43% reduction of NOx. CONCLUSIONS : This study has suggested that applying TiO2 rarely impacts asphalt pavement performance measures such as moisture susceptibility and skid resistance, and that its application may be a better means of reducing air pollution. Further studies, such as proper TiO2 dosage rates and compatibility with various pavement types, are required to broaden and generalize its application.

PURPOSES: The main purpose of this study is to develop a high elastic modulus and low-shrinkage roller-compacted concrete base (RCCB) in order to prevent fatigue cracking and reflective cracking in the asphalt surface layer of composite pavement. Using a rigid base material with low shrinkage can be a solution to this problem. Moreover, a strong rigid base with high elastic modulus is able to shift the location of critical tensile strain from the bottom of the asphalt layer to the bottom of the rigid base layer, which can prevent fatigue cracking in the asphalt layer. METHODS: Sensitivity analysis of composite pavement via numerical methods is implemented to determine an appropriate range of elastic modulus of the rigid base that would eliminate fatigue cracking. Various asphalt thicknesses and elastic moduli of the rigid base are used in the analysis to study their respective influences on fatigue cracking. Low-shrinkage RCC mixture, as determined via laboratory testing with various amounts of a CSA expansion agent (0%, 7%, and 10%), is found to achieve an appropriate low-shrinkage level. Shrinkage of RCC is measured according to KS F 2424. RESULTS : This study shows that composite pavements comprising asphalt thicknesses of (h1) 2 in. with E2 > 19 GPa, 4 in. with E2 > 15 GPa, and 6 in. with E2 > 11 GPa are able to eliminate tensile strain in the asphalt layer, which is the cause of fatigue cracking in this layer. Shrinkage test results demonstrate that a 10% CSA RCC mixture can reduce shrinkage by 84% and 93% as compared to conventional RCC and PCC, respectively. CONCLUSIONS: According to the results of numerical analyses using various design inputs, composite pavements are shown to be able to eliminate fatigue cracking in composite pavement. Additionally, an RCC mixture with 10% CSA admixture is able to reduce or eliminate reflective cracking in asphalt surfaces as a result of the significant shrinkage reduction in the RCC base. Thus, this low-shrinkage base material can be used as an alternative solution to distresses in composite pavement.

This study is carried out to obtain basic data regarding oxidation and reduction reactions, originated on the recycling of waste tungsten hard scraps by oxidation and reduction processes. First, it is estimated that the theoretical Gibbs free energy for the formation reaction of WO2 and WO3 are calculated as ΔG1,000K= -407.335 kJ/mol and ΔG1,000K = -585.679 kJ/mol, from the thermodynamics data reported by Ihsan Barin. In the experiments, the oxidation of pure tungsten rod by oxygen is carried out over a temperature range of 700-1,000oC for 1 h, and it is possible to conclude that the oxidation reaction can be represented by a relatively linear relationship. Second, the reduction of WO2 and WO3 powder by hydrogen is also calculated from the same thermodynamics data, and it can be found that it was difficult for the reduction reaction to occur at 1,027oC, in the case of WO2, but it can happen for temperatures higher than 1127oC. On the other hand, WO3 reduction reaction occurs at the relatively low temperature of 827oC. Based on these results, the reduction experiments are carried out at a temperature range of 500-1,000oC for 15 min to 4 h, in the case of WO3 powder, and it is possible to conclude that the reduction at 900oC for 2h is needed for a perfect reduction reaction.

PURPOSES : The objective of this study is to develop an optimized method of mix design for rapid-set lightweight-formed mortar mix. To achieve this objective, the workability, setting time, and compressive strength of mixes under various conditions of mix design were evaluated. METHODS: The water-bonder ratio, fly-ash substitution ratio, and forming agent injection amount were selected as design variables in the study. The fluidity, setting time, density, and strength of the mortar mix were considered as major evaluation criteria of the mixture, and were subsequently utilized to evaluate the characteristics of the mortar mix under various conditions. RESULTS : The observations made from the mix design process are as follows: 1) the air content and fluidity increase as the forming agent ratio and forming agent ratio increase, respectively; 2) the maximum air content is approximately 20%; 3) the accelerating agent decreases the fluidity of the mortar mix by 15% on average; 4) the forming agent injection ratio and fly-ash substitution ratio yield significant effects on the initial and final set times of the mortar mix; 5) as the forming agent injection ratio and fly-ash substitution ratio increase, the compressive strength of the mortar mix decreases; and 6) the 28-day compressive strengths of the forming agent injection ratio and fly-ash substitution ratio yield the most significant effects. CONCLUSIONS: It is concluded that the governing design variables for the rapid-set lightweight-formed mortar mix are the forming agent injection ratio and fly-ash substitution ratio.

Seismic analyses of a pile under a large rigid basement foundation embedded in the homogeneous soil layer were performed practically by a response displacement method assuming a sinusoidal wave form. However, it is hard to take into account the characteristics of a large mat foundation and a heterogeneous soil layer with the response displacement method. The response displacement method is relevant to the 2D problems for longitudinal structures such as tunnel, underground cave structure, etc., but might not be relevant with isolated foundations for building structures. In this study, seismic pile analysis by a pseudo 3D finite element method was carried out to compare numerical results with results of the response displacement method considering 3D characteristics of a foundation-soil system which is important for the building foundation analyses. Study results show that seismic analyses results of a response displacement method are similar to those of a pseudo 3D numerical method for stiff and dense soil layers, but they are too conservative for a soft soil layer inducing large soil pressures on the foundation wall and large pile displacements due to ignored foundation rigidity and resistance.

The analysis on the international safety management code (ISM Code) and case of foreign national safety management for fishing vessel was conducted to serve as a basic data on the introduction of safety management system (SMS) for a deep-sea fishing vessel in Korea. As a result, Maritime New Zealand (MNZ) has managed operations of SMS in the maritime rules according to the Maritime Transport Act since 1994. MNZ underwent a safe ship management (SSM), which includes elements applied to shipping companies, ship and verification of the ISM Code for ships, except ISM Code application since 1998. In 2014 the introduction of the advanced maritime operator safety system (MOSS) superior to the SSM by MNZ was promoted actively switch and enforcement. Meanwhile, the safe operation manual of Japanese fishing vessel includes large part of the contents of the ISM Code, and voluntary implementation to fit the realities of the fishing vessel. The law application of SMS for a deep-sea fishing vessel after the newly establishment of the Ocean Industry Development Act to SMS would be advantageous to the schematic management, supervision, maintenance and application and, in 2016 from the implementation of maritime safety supervisor for a deep-sea fishing vessel that the management and supervision through the fishing vessel will be the efficient operation. The configuration of the safety management system in a deep-sea fishing vessel should be included as an element of ISM Code. The introduction of such a system is gradually applicable, such as nationality overseas vessel case study of the ISM Code, and vessels that are excluded from the application will be implemented as autonomous as Japan. The results are expected to contribute to sustainable development in the ocean industry safety culture spread throughout the ocean industry through the enhancement of safety fishing competency and safety management responsibility of fisher.
