It has been often noted as a problem that as there are no objective and clear criteria for the repair cost estimate of persistent defects, when a claim arises in relation to an apartment construction, significantly different amounts of compensation may be given for similar defects based on the experience and tendencies of the construction experts asked to make a judgment. For this reason, this research aims to present defect managers with a more reasonable and objective estimation criteria and a system to determine the repair cost of defects based on an analysis of relevant factors. The research findings show that the historical cost system is applied first, and then a standard of estimation is used to estimate the cost for the items that are not included in the historical cost system. The criteria for the repair cost for each defect is as follows: the repair cost for defects arising from a regulation violation is determined by calculating the reconstruction cost of the parts in question after demolishing them; the repair cost for progressive defects is determined based on a contribution ratio proportional to the age of the building; the repair cost for repetitive defects is calculated by considering an alternative to maximize the intended function of the defective parts; and the repair cost for value depreciation defects is determined based on the ratio of the warranty period to the lapsed years. However, repair cost estimation for dual value depreciation defects should be studied in future research.

In buildings on the street, indiscriminate redevelopment are being made by overlooking the relationship with surrounding landscape to create their own unique meaning, due to industrialization progressed rapidly with human needs of longing for something constantly. Selection and methods of two plans, conservation and utilization should be required, considering heritage values on industrial buildings which are being lost and aged in this redevelopment higher. The attempt for the use of modern industrial heritage becomes a hot topic, and several experimental challenges are being made. However, there are rather many cases of causing industrial buildings' depreciation and one-size-fits-all reproduction performance as it applies other examples as standards by recognizing the reproduction of modern industrial heritage as one trend, not focusing on the trend of the times or paradigm, what the times want. To minimize these problems, we focus on how to utilize industrial buildings beyond the importance of industrial buildings' reproduction, considering the quality of local residents' life as well as the expected effect obtainable due to security of local identity and reproduction of buildings, focusing on the concept of community design that offers and forms a way of community life as the design of shares based on unspecified individuals' common life. Community design's core can be called to have diversity rather than undifferentiated unity by pursuing whole unification, since local residents become those who plan design and all people participate in it. In addition, community design achieves integration with other fields as an enlarged design area without limiting in an environmental area, by making indigenously natural characteristics combined with cultural factors in one context so that people may understand the flow of the place. The importance of effects acquired from modern industrial heritage's reproduction has well-known, and the attempt for utilizing aged heritage as a new value and a function has constantly been made. Now, it's time to focus on how long it lasts through this method, rather than modern industrial heritage's reproduction itself. There can be a significance in this study in proposing methodological solutions on modern industrial heritage's reproduction, not to cause depreciation of industrial buildings by recognizing contemporary trends and uniform regeneration performance, multifaceted research is needed for creative, effective development on modern industrial heritage which will occur constantly.

The purpose of this study is to analyze how managers' reporting choices affect asymmetric cost behaviors in manufacturing firms in Korea and Japan. In order to analyze the contents, SG&A, COGS, and operating expenses (OE), which were the targets of the previous studies, were analyzed using the operating costs paid in cash (OC) and the operating expenses before depreciation (OEBD) proposed by Shust and Weiss (2014). The differentiation of cost behavior was analyzed. The analysis revealed, first, that both Korea and Japan showed the difference between cost behavior of OE and OC. Specifically, the cost stickiness of OC was higher than that of OE. In particular, it showed that Korea firms have a higher intensity of tangible fixed assets that are weakening the cost stickiness compared to Japanese firms. Second, the occurrence of depreciation costs weakens the cost stickiness in both countries. Lastly, the higher the debt ratio, the more aggressively the cost reduction of Japanese companies. We hope that this study will help to improve the relationship between the two countries at the academic level when the Korea-Japan relationship cools down.

A phenomenological study was conducted to investigate the experiences of mothers pregnant via in vitro fertilization (IVF). Sample of nine mothers participated. Ten theme clusters emerged when the formulated meanings were organized into categories. During the infertility period, the participants were subject to self- depreciation, envy, anxiety, and depression. It changed their priorities in life from a job-oriented life to one where having a baby was the most important thing. After trying numerous alternative therapies, IVF became their last hope in having a baby. Since the success rate for IVF is low (only 20-30%), the participants for the treatment were overwhelmed with uncertainty, and it led to further anxiety, depression and despair. Success of pregnancy gave them extreme satisfaction, but they became very cautious in their day-to-day life because of their fear of abortion and early delivery. Some were even worried about the side effect of IVF during the pregnancy. Finally, the delivery of the baby gave them relief from the obligation of having a baby. Women did not have any difficulties in rearing a "test tube baby" except in the case of twins. Most women had no ethical difficulty in having a baby by IVF. However they did not wish this information to be revealed to other people. They again turned to IVF to have a son(s) when the resultory child(s) was a daughter(s). This is because of the strong preference for sons in Korean society.

The purpose of this study is to examine the rationality for public organizations' cost allocation method through the case of special post offices. The proper use of allocation method is crucial to promote and nurture the public organization sector. On that note, this paper presents how to apply the proper estimation method. The cost allocation method is to split the total expense into appropriate services and departments. Using the basic expense rate and the standard depreciation rate and area at each post office, the total cost is calculated into the cost per person and area. As a result, the correct cost can be assigned through allocation per according service unit.

This study had carried out an analysis of leaf tobacco production cost by cost items, growing stages, and farm sizes per 10a to provide the basic data for determination of the purchasing price of leaf tobacco by KT&G. Considering the survey results of 12 tobacco farm households, the composition rates of production cost by items revealed as 7-10% for land service, 5-22% for depreciation, 13-25% for material costs, 50-65% for labour cost respectively. The production cost of leaf tobacco by growing stages were shown as 15.3% in nursery bed period, 32.3% in main growing period in field, 30.8% in harvesting period and 21.6% in packing period. The magnitude of wage expenditure was appeared as harvesting stage, packing stage, growing stage on main field and nursery bed stage in order. The amount of material costs were revealed as the growing stage in main field, harvesting stage, nursery bed stage and packing stage respectively. The production costs of leaf tobacco per 10a by farm sizes were shown as 1,615,879won for small farm, 1,446,896won for medium farm and 1,454,408won for large farm respectively. The production cost of leaf tobacco had shown decreasing tendency according to increasing farm sizes. To promote the international market competitiveness of leaf tobacco producing farms, labour saving production technologies and cost effective farm size to decrease tobacco production cost should be developed.

There are customer services jointly provided by two facilities so that each customer will complete the course made up of both facilities' sub-services. The two facilities are assumed invested respectively by an infrastructure owner and one subordinate facility owner, whose partnership is built on their capital investments. This paper presents a mathematical model of Stackelberg competition between the two facility owners to derive their optimal Nash equilibrium. In this study, each facility owner's profit is consisted of fixed revenue fractions of sold services, operating costs (including depreciation cost) and maintenance costs of her facility. The maintenance costs of one facility are incurred both by failures and deterioration due to usage. Moreover, for both facilities, failures are rectified immediately by minimal repairs and preventive maintenance is carried out at a fixed time epoch. Additional assumptions are also employed to develop the model such as customer arrivals are manipulated to follow a Poisson process, and each facility's lifetime is independently Weibull-distributed. The Stackelberg game proceeds as follows. At the first stage of decision making process, the infrastructure owner (acting as a leader) decides the allocation of revenue shares based on her self-interest. After observing the allocation of revenue shares, the subordinate facility owner determines her own optimal price of services. This paper investigates actions and reactions of the two partners in the system. Then analytical conditions are proposed to achieve a unique optimal Nash equilibrium. Finally, some suggestions for further research are discussed.

A capacitor discharge impulse magnetizer using semiconductor switching device is used to produce a high current impulse of short duration in a magnetizing fixture for magnets of the various shapes. The price of today's magnetizer is relatively expensive. This paper described a method for cost estimation of capacitor discharge impulse magnetizer using semiconductor switching device and the economical efficiency analysis. We used a cost structure consisted of five major subsystems. Especially, we estimated the potential for a cost reductions in impulse magnetizer as a function of time using the learning curve, and the potentials of cost by depreciation. The reliable results were obtained by using iron-core fixture coupled to a middle-voltage magnetizer.

In medium voltage electrical distribution networks, reforming the loss reduction is important, and in line with this, the issue of system engineering and use of proper equipment Expansion of distribution systems results in higher system losses and poor voltage regulation. Therefore, an efficient and effective distribution system has become more important. So, proper selection of conductors in the distribution system is crucial as it determines the current density and the resistance of the line. Evaluation of aging conductors for losses and costs imposed in addition to the careful planning of technical and economic networks can be identified in the network design. In this paper the use of imperialist competitive algorithm; genetic algorithm; is proposed to optimal branch conductor selection and reconstruction in radial distribution systems planning. The objective is to minimize the overall cost of annual energy losses and depreciation on the cost of conductors to improve productivity given the maximum current carrying capacity and acceptable voltage levels. Simulations are carried out on 69-bus radial distribution network using genetic algorithm approaches to show the accuracy as well as the efficiency of the proposed solution technique.

Shipbuilding industry is one of the most influential ones in Korea. As shipbuilding industry is labor-intensive, it contributes to enhancing both local economy and national economy. Shipbuilding industry has been downsizing since the end of 2008 due to global financial crisis caused by America's sub-prime mortgage and aggravated by European countries' fiscal deficit. As a large fund is required for a single normal shipbuilding contract, fund raising is one of the most important elements in shipbuilding contract. Shipbuilding contract, requires refund guarantee in order for a buyer to reimburse the progressive payment paid to a builder. The disputes under shipbuilding contracts are mostly settled by arbitration rather than by law suit. English laws and English courts have been preferred for the choice of law as well as for the choice of forum. Due to depreciation of the ship value since the end of 2008, a number of buyers are trying to cancel the contract by raising unjust claim under the contract. Once disputes occurs regarding shipbuilding contract, a large amount of loss is inevitable. In order to mitigate the disputes arising from the shipbuilding contract, careful caution is required in drafting a shipbuilding contract.
