이 연구는 개인들의 노동공급행위를 설명하는 중요한 이론 중 하나인 '인적자본론'이 여성들의 취업특성을 설명하는 데에 여전히 유효한지에 대한 문제제기에서 출발했다. 구체적으로 이 연구는 여성들이 지닌 인적자본이 여성들의 취업결정과 취업직종에 어떠한 영향을 미치는지를 경험적으로 분석했다. 이 연구에서 살펴보고자 하는 가설은 크게 두 가지로서, 첫째는 여성들의 인적자본이 여성들의 취업률에는 어떤 영향을 미치는지이며, 둘째는 여성들의 인적 자본이 여성들의 취업직종에는 어떤 영향을 미치는지이다. 한국사회 고학력 여성들의 경제활동참여율이 매우 저조하다는 데에서 알 수 있듯이, 여성들이 지닌 인적자본이 여성들의 취업률에 별다른 영향을 미치지 못할 것이라는 점이 이 연구의 주된 가설이다 하지만 일단 취업을 한 여성들의 경우에는 그들이 갖고 있는 인적자본이 취업직종에서는 상당한 설명력을 지닐 것으로 여겨져 이러한 내용으로 두 번째 가설이 구성되었다. 분석 결과, 가설에서 설정한 대로 인적자본론의 이론적 예측과 달리, 여성들의 취업결정에 인적자본은 별다른 영향을 미치지 못하거나 혹은 정반대로 부(-)적인 영향을 미치는 것으로 나타났다. 특히 가장 중요한 인적자본 중의 하나인 '학력'의 효과를 살펴보면, 학력이 높을수록 뚜렷하게 일률적으로 취업률이 낮아짐을 확인해 볼 수 있었다. 그밖에, 여성들이 지닌 자격증이나 취업 훈련 여부, 또 건강 상태 등과 같은 인적자본 요소도 여성들의 취업결정에는 별다른 영향을 미치지 못하는 것으로 나타났다 한편 인적자본은 여성들의 취업직종에는 상당한 정도의 정(+)적인 영향을 미치는 것으로 나타났지만. 이 분석결과도 실질적인 내용을 따져보니 그다지 유효한 영향 효과라고 보기 어려웠다 취업직종과 연령 및 학력과의 회귀분석 결과 여성 취업직종의 열악한 상황을 재확인해 볼 수 있었다. 따라서 한국사회 여성들의 인적자본은 여성들의 취업 결정 및 취업유형에 의미있는 변수가 되지 못한다고 할 수 있다.

While a performance type guarantee is required as a security for non-performance risk by a seller, a payment guarantee is used as a security for non-payment risk by a buyer(or a borrower in a loan agreement). A payment guarantee is a type of independent bank guarantee, bank guarantee, bond, demand guarantee, or standby letter of credit. A guarantor accepts a credit risk of a principal which is normally a buyer in a contract for sale of goods. A payment guarantee is independent of the underlying relationship between the applicant and the beneficiary. The guarantor is only empowered to examine the beneficiary's demand and determine the payment on its face to the terms of the guarantee. A payment guarantee is thus different from a suretyship. The principle of independence carries a significant advantages for a guarantor as well as for a beneficiary. While a documentary credit requires B/L, commercial invoice, packing list, inspection certificate, etc., a typical payment guarantee does not require any evidence for a seller's performance of the underlying contract other than written demand. In this respect payment guarnatee can be a more secured facility than a documentary credit. A payment guarantee normally comes into force from the issuing date and shall remain in effect until all sums guaranteed shall be paid in full by a buyer(or a borrower) or by a guarantor. Although a guarantor shall pay a demand made in accordance with the terms and conditions of the payment guarantee, a payment demand may be denied when it is determined to be abusive or unfair.

Although the problem about a token of parents' gratitude is restricted by small number of teachers, it must be solved for normal and good schooling. The purpose of this study was to investigate the problem about a token of parents' gratitude, an extent of a token of parents' gratitude, seriousness of a token of parents' gratitude, the experience of a token of parents' gratitude, an amount of money a token of parents' gratitude, the time of a token of parents' gratitude, a compensation of a token of parents' gratitude using a questionnaire to 549 parents. And a Chi-square test was used as a research tool for this study. This study indicates that many parents recognize a token of parents' gratitude as money or gift certificate. And most parents recognize different significantly about a token of parents' gratitude according to teachers' sex, ages, level of school, and type of school. We do not need a vast and experimental revolution in education based on unproved reasoning. If we want to be normal and good schooling, we have to make an effort small changes which solve a problem of a token of parents' gratitude. Our educational policies have to move from vast approaches generated from 'above' with political purpose to more particular approaches based on specific problems and generated by the community.

During five years (Year 2009~2013), Total victims of 72 %(81,560 people) and those 50.6 %(1,258 people) of death accident occurs in small scale construction site which operate 2 million USD less construction budget. Especially, falling death accident account for 785 people, in the share of 33.2 %(261 people) death disaster takes due to defect of original cause materials. The major safety issues in small scale work place take place while scaffold installation, disassembling, work-plate improper installation or non-professional skills of workers. Furthermore, labor subcontract systems make small construction site shortage of resources. Those workers regard work-plate as unnecessary and consumables supplies. Because of that most of workers use unsafe workplace in most construction site. Therefore, in order to prevent falling accident occurring in small scale work site, government should organize related regulations such as "Work site safety construction method" and then expands education support, financial aid, and sourcing safety supplies for work plate which offer broad variety experiences. Also, introduce certificate solutions for various work plates to improve safety function such as anchoring type method and anti sliding function.

Influence of the adaptors on the calibration of $100{\mu}H$ inductance standard was studied as a function of torque, applied when tightening the standard inductor terminal with the adaptor. Two different homemade adaptors of BPO gold-plated brass (BPO-Au) and banana-copper (BN-Cu) were made for the connection between the LCR meter and the inductance standard. The measured inductance (L) of the standard inductor and the contact resistance ($R_C$) between the adaptor and the standard inductor terminal showed exponential decreases against the torque increase from $25cN{\cdot}m$ to $150cN{\cdot}m$. The measured L and the calculated equivalence series resistance ($R_S$) were dependent on the adaptor type as well as on the $R_C$. The results of the adaptor analysis imply that the BPO-Au adaptor with the lower $R_C$ is more suitable for the inductance calibration. The calculated inductance of $99.956{\mu}H$ corrected by subtraction of the adaptor inductance and the contact resistance contributions from the measured value using the BPO-Au adaptor agreed well with the certificate ($99.948{\mu}H$) of the PTB within the measurement uncertainty of $140{\mu}H/H$.

Various kinds of ballast water treatment systems (BWTS) have been developed corresponding to reinforced IMO rules for marine environment. Some of them got the certificate of IMO and others are waiting for it. Selection of optimum BWTS is very important. Optimum BWTS means not only functional requirements but also economic efficiency. This paper presents economic analysis model for optimum BWTS according to ship type and size. In this study 10 kinds of BWTS whose initial installation cost and maintenance cost are known are analyzed based on present worth method. It is assumed that all BWTS satisfy minimum functional requirements and we need to consider different economical efficiency. Through the economic analysis we could select optimum BWTS.

It is well known that the polymer matrix composite materials have good specific strength, making them appropriate for use in transport vehicle. Since the property of composite materials can be obtained only after manufacturing parts, the property depends on greatly on the fabrication process, which is different from metallic system. Therefore, in order to use composite materials for aircraft, the certifying agency requires a robust database with extensive tests and proof of the process unlike metals. Recently developed material qualification methodology by NCAMP (National Center for Advanced Materials Performance) has been accepted by FAA and EASA and can be applied to type certificate reducing time and cost of developing a composite materials database for aircraft application. This paper summarizes a study to establish the composite materials database to apply the NCAMP methodology to composite materials characterization for composite aircraft and to provide the effective materials database through Aerospace Composite Materials Data Center to be approved by Korea Civil Aviation Certification Agency.

In this paper, we analyzed the elements of measurement uncertainty on electrical performance test which are the most important things in photovoltaic module performance test. Repeating the performance test by 6 men, the measurement uncertainty could be calculated. In this experiment, Solar Simulator (A-Class pulse type) used for domestic certificate test of PV module is Pasan IIIb (Balval, Switzerland). The possible elements of the measurement uncertain that could effect electrical performance test of PV module are reference cell, spectrum correction, error from measurement repetition, test condition, stability and uniformity of artificial solar simulator. To find the measurement uncertainty, 6 men repeated the test by 10 times. And the results were that numerical average value was 124.44W and measurement uncertainty was $124.44W{\pm}0.36W$ with 95% confidence level for 125W PV module(KD-5125).
