  • The traditional village forests in Korea such as Dangsan forests and Bibo forests form unique cultural landscape and they are national cultural assets with histories of more than several hundred years. It is important to have sustainable right to enjoy cultural heritage as well as maintaining its authenticity. Cultural assets are meaningful only when they are managed to succeed to next generations. Dangsan forests and Bibo forests need to be named properly and recognized by society as a precious cultural heritage for many generations to come in order to claim the value as traditional cultural landscapes in Korea. The traditional village forest in Dangin-ri, Wando-gun was composed of a Dangsan forest and five Bibo forests. Although this traditional village forest is large in size, it was not on the report of Cultural Heritage Administration(2005) investigated for 'Village forest of island region in Jeollanam-do'. The objective of this study was to investigate the characteristics of the traditional village forest in Dangin-ri to grant correct name and to enhance its value. In this study the characteristics of a Dangsan forest and five Bibo forests were investigated from 2006 to 2013 for physical features such as size, shape, location, tree species composition, and diameter at breast height(DBH), as well as cultural aspects and tradition. Currently the naming and designation of natural monuments by the cultural heritage administration(CHA) is based on the rule enacted in 1934. Many Dangsan forests were named as evergreen forests. This type of names does not represent the meaning of traditional village forest. It was suggested that this traditional village forest is to be named as 'Dangsan Forest and Bibo Forests at Dangin-ri, Wando-gun'. This traditional village forest needs to reclaim authenticity and rebuild its original appearance by restoration of the disturbed areas, especially in Bibo forest I.

  • The domestic CM business market has continued to grow, but its size is relatively small yet in comparison with the total size of the domestic construction industry. Evaluation of CM projects was conducted through questionnaire surveys. Both clients and CM firms showed positive satisfaction levels. Nevertheless, the clients' satisfaction levels were relatively low in safety management, cost management, and document and information management. Superior areas of CM tasks were time management and recovery scheduling, quality control and technical instruction, and design value engineering. On the other hand, inferior areas of CM tasks were claim analysis and dispute resolution, cost estimation, and life cycle costing. Both entities have agreed with the positive effects of CM involvement in terms of cost saving, time reduction, quality improvement, and safety incidents prevention to at least 0~5% extent.

  • Recently, the number of customers who want natural cosmetics without petroleum originated cosmetic ingredients is increasing over the world, however, there are few natural cosmetics that claim functionality in the products. Because there are few functional cosmetic ingredients from nature and though so, it is very difficult to stabilize the final products manufactured by using those functional cosmetic ingredients in the long period. This study is on stabilization of oleanolic acid, insoluble anti-wrinkle cosmetic ingredients from nature, with hydrogenated lecithin in the solubilization product, aiming for developing a formulation of solubilization products which can be certified as organic cosmetics. In case of other synthetic solubilizers, they showed unstability at $45^{\circ}C$ within 2 ~ 3 days, however, for natural origin hydrogenated lecithin a stable product was made without particle size change during 4 weeks. The stability of oleanolic acid in the solubilization product was measured for 24 weeks at $25^{\circ}C$ and $40^{\circ}C$, both samples showed over 90 wt% value of the initial one, which can prove that oleanolic acid was stabilized in the product without any degradation. Also through clinical tests, the effect of moisturizing, anti-wrinkle, safety were confirmed.

The Impact of Government Funds in Venture Capital on Investment in Early-Stage Firms: An Evidence from Korean Venture Capital (벤처캐피탈에 대한 정부출자금의 초기단계기업 투자에 대한 영향: 한국의 벤처캐피탈에 관한 실증연구)

  • This study examines the impact of government funds to venture capital on investment in early-stage firms. We provide novel explanations about this relationship focusing on mechanisms by which government funds influence the perceived uncertainty, decision about investment priority, scale economy of investment, information asymmetry in investment decision, and capital expense. We argue that venture capital's investment in early-stage firms increases as government funds increase and as government funds are explicitly directed for early-stage firms. However, we further claim that the impact of government funds on early-stage investment will be decreasing as their size increases and finally be reverted to negative impact beyond a certain amount of funds to show inverse-U relationship. Our empirical examination using data from 105 Korean venture firms active as of 2013 consistently supports the claims. This study contributes to the venture capital literature by providing novel arguments about mechanisms and effects of policy intervention in venture capital. In practice, we expect our results will provide an opportunity for relevant policy makers to review their venture support policy based on empirical evidences for policy effects.

  • Our current food hygiene law mandates nutrition label (NL) for the special nutrition foods, health support foods, instant foods, and foods with certain nutrient emphasized note, only. Currently more processed foods are bearing nutrition labels though the format is quite inconsistant. This study examined the status on current nutrition labeling practices for the processed foods that are retailed in the supermarket. The obtained information was assessed in the aspects of numerical data presentation on nutrients content, descriptive terms, health claim, and the format. The results are summarized as follows. 1) Foods with NL are limited to the food category specified by current hygiene law while voluntary nutition labeling is few. 2) Descriptive terms such as free, low, and sufficient are not substantiated with quantitative data. The efficacy of microelements which has not been clalified yet are overemphasized but major nutrients are ignored. 3) The regulations for the descriptive terms are set on the base of the nutrient content per 100g or 100ml under current nutrition labeling act. It would mislead consumers thus the definition for these descriptor be better set on the unit of the amount of food customary eaten at one time. For this the standard serving size should be set officially. 4) Quantitative nutrition information given on food products is difficult to compare because of the lack in formality. The title of NL, load and kinds of nutritents, order of nutrients listed, the unit of expression, RDA comparision, and reference RDA are inconsistant among the foods similar in dietary property. Uniform format is needed to give NL the credibility and usefulness. Proividing nutrition information to the consumers with NL is a worldwide practice though its efficacy has been controversial. Under newly legistered health promotion law in Korean nutrition education is esxpected to take part in to improve national nutrition condition and NL would education is expected to take part in to improve national nutrition condition and NL would be a potent tool for public nutritions education. It appears to be the time to mandate NL to all the processed foods in the market. The result of present study would initiate further consumer experiments related to NL. Various interest groups such as food and nutrition professions, public health organizations, government regulatory agencies, food producers and marketers, and consumer groups need to particepate and communicate for the legislation of NL and the development of NL format.

  • P-value is the probability of observing a current sample and possibly other samples departing equally or more extremely from the null hypothesis toward postulated alternative hypothesis. When p-value is less than a certain level called ${\alpha}$(= 0:05), researchers claim that the alternative hypothesis is supported empirically. Unfortunately, some findings discovered in that way are not reproducible, partly because the p-value itself is a statistic vulnerable to random variation. Boos and Stefanski (2011) suggests calculating the upper limit of p-value in hypothesis testing, using a bootstrap predictive distribution. To determine the sample size of a replication study, this study proposes thought experiments by simulating boosted bootstrap samples of different sizes from given observations. The method is illustrated for the cases of two-group comparison and multiple linear regression. This study also addresses the reproducibility of the points in the given 95% confidence interval. Numerical examples show that the center point is covered by 95% confidence intervals generated from bootstrap resamples. However, end points are covered with a 50% chance. Hence this study draws the graph of the reproducibility rate for each parameter in the confidence interval.

  • We measured nitrate and other nutrients in sediment pore waters retrieved from three sites at the southern upper-tidal flats of the Ganghwa Island. Denitrification rate is estimated by applying a simple 1-D model to the nitrate profiles. Results from Jangwha and Dongmak sites are $7.8{\sim}9.4{\times}10^{-7}{\mu}mol{\cdot}cm^{-2}{\cdot}sec^{-1}$, and $1.4{\sim}3.6{\times}10^{-7}{\mu}mol{\cdot}cm^{-2}{\cdot}sec^{-1}$, respectively. Rates are comparable to those reported around the world in an order of magnitude. Denitrification was lower in summer. The rates were about 1.5 times higher at site where the surface sediments consist of relatively coarser particles. This implies that particle size would control the reactant supply to the subsurface sediment. One may claim the denitrification as an evidence of the biogeochemical purification function of tidal flat. However, the purification seems not a general attribute of a tidal flat when whole system is scrutinized by a thermodynamic criterion. Currently the term 'tidal flat' is used when describing the diverse coastal wetlands such as salt marshes, sandy tidal flats and muddy tidal flats, which exhibit quite different ecological functions. Thus it is worthy of mentioning that the classification of coastal wetlands on the basis of sedimentological characteristics and biogeochemical functions should facilitate our understanding.

  • A new cost management system, called Activity Based Costing (ABC) system, has arisen to solve the limitation of a Traditional Cost Accounting (TCA) system until last two decades and ABC has been applied by many companies. TCA systems have limitation in tracing cost because they arbitrarily allocate overhead cost to the cost objects without standard for direct cost distribution. ABC is an accounting system that assigns costs to products or services based on the resources they consume. The costs of all activities are traced to the products for which they are performed. Therefore ABC is a cost management system that provides a matrix to accurately quantify consumed resources triggered by activities and activities triggered by products and services. There is little implementation of ABC in the health services field, one of service industries, due to complicated and many activities, and volatile cost object. However, the necessity for applying reasonable cost accounting system is largely issuing as strategy responding hostile environment, and financial pressure, and it is imperative to implement the Activity Based Costing (ABC) system. Therefore, this study presents the framework to develop ABC system for total health service organizations. Cost objects in this study base on medical service activities per health insurance claim from one general hospital located in Metropolitan Statistical Areas (MSAs). Medical service activities include all health insurance claims in the hospital. The purpose of the study is presenting useful tools and basic frame to develop Activity Based Costing system for health service organizations which want to use ABC system. The steps to develop ABC system for health service organizations are following: 1. Identifying of activity centers; 2. Definition of cost objects and activity by activity center; 3. Analysis of activity and tracing activity contribution; 4. Allocation of direct cost for specific activity; 5. Allocation of indirect cost for specific activity; 6. Allocation of depreciation for facilities, applicants, and consumption goods; 7. Allocation of administration cost; 8. Allocation of cost among activity centers; and 9. Tracing cost of cost objects by activity center. This study identified necessary information from existing reports which hospitals generally made by each step, and defined outcome which had to be produced in each step using this information. The steps of this study had limitation to apply all different size hospitals because the steps were structured ABC system by one hospital, however, this study used similar basic framework and methods with general cases. When a health service organization want to apply Activity Based Costing (ABC) system on all activities of it in future days, this study is very useful to design system structure in the health service organization.

  • The accident of the midair collision, passengers' falling or goods' dropping occurs or supersonic aircraft make a sonic boom during their conveying passengers or goods to the destination. The accident in transmit damages the their parties on the surface or their properties. In these cases, the third parties who were harmed to their lives or properties have the right to claim damages against the air carrier who caused them. These matters have become one of the important things since aircraft conveyed passengers and goods. Therefore, it is a great concern to settle these matters by law. But the Safety of the present aircraft has been much increased and the aircraft have become larger in size. Its flight altitude became higher than before. So the relationship of the aircraft to the third parties is much different from that of the earlier aircraft. The air transport is now indispensable to our life. It is not so easy to control these matters. In the early part of 20th century, when the third parties suffered the damage, many European countries made laws on the basis of the principle of liability without fault. But each country had a variety of its own law, and different kinds of difficulties have been brought about. Accordingly, the Rome Convention on Surface Damage (1933, 1952, 1978) has been made and revised. In spite of being revised, it contains many problems, and is not carried into effect world-wide. On the other hand, there are no regulations about the compensation of the third parties damaged in Korean existing laws. In case the damage is brought about to them, it is obviously true that the settlement of the liability of compensation for damage should be made by the general principle on the tort in domestic laws. At this point, it is urgent that we make a special law though the domestic legislation as a preliminary measure before we sign the international convention to save third damaged. It is desirable that we should, for the responsibility of the air carriage for the demage of the third parties on the surface, bring in the theory of the absolute liability in view of the legislation of many conutries. As the aircraft fly in the sky, their flight always contains some danger. It is very difficult to prove the fault, and the operator should suffer the principle of liability without fault or the similiar one. In case the liability without fault will be imposed upon the operator for the damage of the third parties, it is necessary to bring in the liability protection system for the protection and up upbringing of the air carriage. The Burden of danger of the air carriage will be reduced by introducing the system. A domestic legislation measure should be necessarily taken as soon as possible as a legal security measure on these matters.

  • Concerning the risk factors of the outbreak of a fire in a traditional market, most of those markets are located in downtown areas or residential areas; thus, although their location may be favorable in terms of marketability, they face a potential risk in that a fire may develop into a large blaze owing to poor environment or the absence of facilities prepared for disaster during a fire. Moreover, as many people are densely poised in the markets, it is very probable that a fire may occur owing to the excessive use of heaters in the winter as well as the reckless use of electric and gas facilities. It seems that traditional markets encounter difficulty being insured against fire, because of their vulnerability and that the vast majority of small-scale sellers are likely to suffer mental anguish and tremendous physical injury in case of a fire. However, most of those sellers in the traditional markets are hand-to-mouth sellers, and they lack awareness of safety concerns and have insufficient experience in safe facility management. As small-scale sellers constitute the majority in the traditional market, the subscription rate of fire insurance in most of the traditional markets is low for the reasons of their needy circumstances and their financial burden. Statistically, the subscription by street vendors is non-existent; therefore, these vendors have a fairly limited access to indemnification after fire damage. Because of these problems, this study's purpose is to identify the current level of insurance subscription by these markets, which are exposed to poor facilities and vulnerability to fire. In order to fix this, it appears that shop owners and consumers will have to band together. For this study, we executed a fire policyholder fact-finding mission at traditional markets with approximately 108 and 981 stores. The research method was executed by an investigation using one-on-one individual interviews using a questionnaire. The contents investigated current insurance subscriptions. The method of analysis looked at the difference of insured amount according to volume size through cross-tabulation of the difference of insured amount by possession form, difference of insured amount by market form, difference of insured amount by category of business, difference of insured amount by market size, etc. Furthermore, the study should be used to propose solutions for problems through theoretical review with the use of a literature research, because the field case study was through interviews with the persons concerned, and the survey of the current insurance subscriptions by traditional market shopkeepers. The traditional market would generally have difficulty affording fire insurance. Fire insurance subscription rates of most of the market proved to be inactive, because of the economic burden of payment. Lack of funds is thought to be the main factor that causes a lack of realization about the necessity of fire insurance. In addition to expensive insurance premiums, sometimes, the companies' valuation of the businesses is lower than their actual valuations, and they do not pay out enough during a claim. The research presents an improvement plan that, when presented at the traditional markets, may strengthen their ability to procure fire insurance through the help of the central government. Researchers connected with the traditional market mainly accomplish the initial research. However, although this research has its limitations, it offers considerable benefits. For future researchers, I would suggest looking at several regions for comparison.
