The confirming bank undertakes to make payment to the beneficiary, provided that a complying presentation is made and complies with its confirmation. In case L/C fraud is evident, though, the confirming bank as well as the issuing bank does not have the obligation to make payment. That is, the confirming bank does not take the risks involving documentary fraud. The confirming bank cannot exercise the right to recourse toward the beneficiary or the nominated bank when the issuing bank finds the discrepancies which the confirming bank has not noticed. This is because under UCP600, the issuing bank or the confirming bank cannot refuse to make payment with the cause of documentary discrepancy after 5 banking days following the presentation of documents. Even if the issuing bank accepts the discrepant documents following the confirming bank's request to do so, the confirming bank does not have the responsibility for the confirmation. When under Usance Negotiation Credit, the confirming bank acts as the nominated bank, the confirming bank should make payment in no time if the beneficiary presents complying documents. Therefore, unless the confirming bank intends to make immediate payment, they should consider using Deferred Payment or Acceptance L/C in Usance Credit. It is also safer for the beneficiary to have the reimbursing bank's undertaking to the reimbursement than just have confirmation of the credit because in the latter case they may not have full payment due to disputes regarding discrepancies of the documents even if they have confirmation of the credit.

During last five years several workshops and seminars among social work educators, in and out country, has taken place. In those gatherings there has been, criticism on American model on which curriculum of social work in Korea has mainly based, and many proposals which most developing countries should consider and adopt for developing their own curriculums. The proposals could be summarized as follows; 1. Specification of developmental functions of social work should be made so that the curriculum could involve. It also must come from own societal needs and own national development task. 2. Social work should participate and make contribution to plan and solve the main social problems in own countries. 3. Clarification of educational objective in undergraduate level should be made and one of them must be related to the first professional degree. 4. There should be the courses which provide the content of macro level participation. How much of the proposals are reflected in the current curriculum of Korea? What are the problems Korean social work education has been faced in connection with reflecting the proposals? What kinds of task we should or could perform in order to adopt the proposals? These are the questions which deserved to be studied. The followings are the answers to the questions; 1. The new courses such as social welfare policy and planning, Social Development, Population Dynamics and Family Planning, Social problems, Special Issues in Social Welfare, etc, are placed in the curriculum. 2. Though the new courses are added the courses of case work, group work, and community organization are strongly remained it means that integrative method is not quite adopted and that conflicts are taking place between new and old fashion. 3. Fieldwork placement policy has been changes from concurrent to block and from social work method oriented to social problem oriented. 4. There are lack of integration among the all courses, of consistency between pre and post courses and connection among the related courses. 5. Establishment of image of social worker with B, A. degree should be urgently taken place. It can't be done by social work field alone but by cooperation with all the forces related to the social work practice. 6. B. A. graduate should have a common base of knowledge and competence. It could be come from the clear and specified objectives of undergraduate level education. And agreement among the member schools on the objectives can call on the fundamental similarities in each curriculums. Different programs from one school to another can be tolerated as long as there are fundamental similarities among the schools. Basic concepts and framework of social work should be kept clearly. It is a slow and long process to make social work recognized as a profession in the developing countries. Korea can't be and exception. Failure of having social work be indegenous can't be the reason to refuse an change the basic concepts of social work. One of he most important task which social work education in Korea must achieve in the near future is to establish the minimum requirement courses in the curriculum. Social work field, on the other hand, must find the positions for the social works in the various settings and institute. Clear role and image of social worker can be obtained by doing that.

To determine a favorable substrate formulation for Grifola frondosa, physicochemical conditions, culture properties, and yields according to various substrate formulations were investigated. Based on these analyses, T4 (80:5:15 ratio of oak sawdust to dried bean-curd refuse to corn husk) resulted in a shorter cultivation period and higher yields (weight of fresh mushrooms harvested at maturity) than those of other treatments. The physicochemical properties of T4 were pH 5.4, 2.4% crude fat contents, 54 C/N ratio, 74.3% porosity, and 0.26 g/cm3 bulk density. These results emphasize the importance of optimal substrate development on the production efficiency of G. frondosa mushrooms and have implications for commercial applications.

Objectives: The purpose of this study is to evaluate the clinical effects of Muscle Energy Technique (MET) for peroneal nerve palsy after normal delivery. Methods: Two patients with peroneal nerve palsy were treated with acupuncture, moxibustion, cupping and MET. MET was performed in piriform, gluteus medius, anterior tibial and adductor muscles. To evaluate the effect of MET, we analyzed Ankle dorsiflexion range of motion (ROM), Manual Muscle Test (MMT), Numerical Rating Scale (NRS) and Ankle Hindfoot Scale (AHS). Results: In Case 1, ROM score was changed from −5 to 20, and MMT score was changed from 0 to 4. NRS score was changed from 5 to 1, and her AHS score was changed from 54 to 94 after treatment. In Case 2, ROM score was changed from 0 to 20, and her MMT score was changed from 1 to 5. NRS score was changed from 4 to 1, and her AHS score was changed from 64 to 97 after treatment. Conclusions: MET may be a useful treatment for patients who, shortly after childbirth or while breastfeeding, strongly refuse to treat the irritation.

To investigate the seasonal changes of various organic and inorganic compounds in compost, carbon compounds in compost were analyzed at various composting periods. Contents of organic matter, cellulose, total carbon, organic carbon and biodegradable carbon in compost were decreased with the progress of composting. In contrast, contents of lignin and nonbiodegradable carbon were increased a little with the progress of composting, but effective contents of lignin were decreased with the lapse of composting time, while effective contents of nonbiodegradable carbon were not changed. Total carbon contents in organic matter in compost were decreased within 9 weeks after composting, and then increased thereafter. Difference between average values of total and biodegradable carbon contents was 6.2%. Actual decay rates of all the carbon compounds were higher than decay rates of the compounds at all the experimental periods. Both of actual decay rate and decay rate of all the carbon compounds were increased rapidly within 2 weeks after composting, and thereafter the rates were increased slightly with the lapse of composting time. Especially the decay rates of cellulose were increased from 9 to 21 weeks after composting. Actual degradation capacity showed the same tendency to degradation capacity of all the carbon compounds in compost. Decay rate and degradation capacity of lignin in compost had minus values, while actual decay rate and actual degradation capacity had plus values. Highly positive correlations were observed among organic matter, cellulose, total carbon and biodegradable carbon one another. Nonbiodegradable carbon showed highly negative correlation with organic matter, cellulose, total carbon, organic carbon and biodegradable carbon, respectively. The same tendencies were observed between lignin and organic matter, cellulose, total carbon, organic carbon and biodegradable carbon. Highly positive correlation was observed between lignin and nonbiodegradable carbon in compost.

In order to examine the seasonal variation of organic and inorganic nitrogen compounds, nitrogen compounds in compost were determined at various composting periods. Total nitrogen, organic nitrogen and biodegradable nitrogen contents in compost were almost not changed, while nonbiodegradable nitrogen contents were increased a little with the lapse of composting time. But effective contents of total nitrogen, organic nitrogen and biodegradable nitrogen were decreased with the progress of composting, while effective contents of nonbiodegradable nitrogen were not changed during composting. Ammonium nitrogen contents in compost were highest at the start of composting, and then the contents were decreased with the lapse of composting time. But after turning the contents were increased again, and thereafter the contents were decreased with the progress of composting. Nitrate contents showed a tendency adverse to ammonium nitrogen contents. Organic nitrogens in organic matter in compost were increased slowly within 9 weeks after composting, and thereafter the contents were increased rapidly to 21 weeks after composting. Total nitrogen contents determined by $F{\"{o}}rster$ Method were higher than those determined by Kjeldahl Method. Total nitrogen contents determined by Kjeldahl Method were 6% higher than biodegradable nitrogen contents determined by $F{\"{o}}rster$ Method. Loss of nitrogen in compost was highest at early periods of composting and its losses determined by Kjeldahl Method and $F{\"{o}}rster$ Method in 30 weeks after composting were 50% and 48% of total nitrogen, respectively. Highly positive correlations were observed among total nitrogen determined by Kjeldahl Method, biodegradable nitrogen determined by Kjeldahl Method, total nitrogen determined by $F{\"{o}}rster$ Method and biodegradable nitrogen determined by $F{\"{o}}rster$ Method one another.

In a broad term, health and medical data means all patient information that has been generated or circulated in government health and medical policies, such as medical research and public health, and all sorts of health and medical fields as well as patients' personal data, referred as medical data (filled out as medical record forms) by medical institutions. The kinds of health and medical data in medical records are prescribed by Articles on required medical data and the terms of recordkeeping in the Enforcement Decree of the Medical Service Act. As EMR, OCS, LIS, telemedicine and u-health emerges, sharing and protecting digital health and medical data is at issue in these days. At medical institutions, health and medical data, such as medical records, is classified as "sensitive information" and thus is protected strictly. However, due to the circulative property of information, health and medical data can be public as well as being private. The legal grounds of health and medical data as such are based on the right to informational self-determination, which is one of the fundamental rights derived from the Constitution. In there, patients' rights to refuse the collection of information, to control recordkeeping (to demand access, correction or deletion) and to control using and sharing of information are rooted. In any processing of health and medical data, such as generating, recording, storing, using or disposing, privacy can be violated in many ways, including the leakage, forgery, falsification or abuse of information. That is why laws, such as the Medical Service Act and the Personal Data Protection Law, and the Guideline for Protection of Personal Data at Medical Institutions (by the Ministry of Health and Welfare) provide for technical, physical, administrative and legal safeguards on those who handle personal data (health and medical information-processing personnel and medical institutions). The Personal Data Protection Law provides for the collection, use and sharing of personal data, and the regulation thereon, the disposal of information, the means of receiving consent, and the regulation of processing of personal data. On the contrary, health and medical data can be inspected or delivered of the copies, based on the principle of restriction on fundamental rights prescribed by the Constitution. For instance, Article 21(Access to Record) of the Medical Service Act, and the Personal Data Protection Law prescribe self-disclosure, the release of information by family members or by laws, the exchange of medical data due to patient transfer, the secondary use of medical data, such as medical research, and the release of information and the release of information required by the Personal Data Protection Law.

Agrocybe cylindracea was cultured in a bag, in which sawdust culture medium (1 kg) is put in a plastic bag (PE), with poplar sawdust, rice bran, wheat bran, and dried bean curd refuse in the ratio of 70:10:10:10 (v/v). 2% of the culture medium was inoculated with the liquid starter of Agrocybe cylindracea, and this was incubated at $25^{\circ}C$. After incubation, the A. cylindracea was further cultured by cutting the top vinyl portion of the bag down to the level of the culture medium surface of the first inoculation part. The cut culture medium was placed in a growth room at $25^{\circ}C$, and pin-heading was induced under light irradiation at 99% humidity and 1,000 ppm $CO_$ level for 3days. When the grow the environment was controlled at 95% humidity and $21^{\circ}C$, the bending of the stem was less as compared to that when the cap of the bag had been removed. The number of effective fruiting bodies per bag increased by 140% (28.8), the quantity per bag increased by 29.5%, and 148.5 g A. cylindracea could be potentially harvested.

This study analyzed the physicochemical properties and combustion characteristics of dry food waste to evaluate the possibility of using food waste as a solid refuse fuel (SRF). The characteristics of dry food waste as a fuel were analyzed by comparing the difference in properties with SRF, and the combustion characteristics after conversion into fuel were identified. Ultimate analysis, proximate analysis, calorific value analysis, and TGA analysis were conducted using two types of food waste and two types of SRF, and the following results were obtained. The moisture content and ash content of dry food waste were 1.7~10.0 wt.% and 7.8~11.7 wt.%, respectively, which satisfied the quality standards for SRF. The low calorific value of dry food waste was 4,000 ~ 4,720 kcal/kg, which was higher than the quality standard of 3,500 kcal/kg for SRF. As a result of TGA analysis of dry food waste, the combustion reaction started at about 200 ℃ and the highest burning rate was at about 500 ℃. After moisture evaporation between 100 and 200 ℃, initial volatile matter, carbon and residual volatile matter were released and burned between 200 and 500 ℃. Based on the high calorific value and low moisture and ash content of dry food waste, it is considered that it is possible to convert dry food waste into SRF through the application of efficient drying technology and strict quality standard inspection in the future.

With the expansion of platform-based taxi service, mobility and convenience of users are getting better. However, due to profitability problem, marginalized areas in the supply of the service are expected to appear. As such, this study analyzed spatial marginalization of taxi service caused by imbalance in supply and demand during the night-time when public transportation service is suspended. According to hot-spot analysis of taxi, outskirt of a city and residential areas showed high vacancy and greater number of drop-offs compared to the number of pick-ups. On the contrary, they were confirmed low in the center and sub-centers of a city. Centrality analysis also showed a similar pattern with hot-spot analysis. Due to this, drivers may refuse to pick up a customer bound for an area with lower out-degree centrality compared to in-degree centrality as it might be difficult for the drivers to pick up another customer after dropping off the current customer. Thus, customers may need to wait for a taxi for a longer time. For this reason, improvement in spatial marginalization caused by mismatch of supply and demand is required. Also, the outcome of this study is expected to be utilized as a basic data.
