The fibrous raw materials in packaging-grade paper production in Korea were mainly obtained from waste paper. The use of recycled paper has both positive and negative impacts in papermaking process. The primary positive impacts are the environmental protection and manufacturing cost reduction, and the negative impacts are the quality reduction in paper quality and the accumulation of heavy metals and other pollutants in wet- and dry-end process. This study was carried out to consider the optimum acid decomposition system with the highest recovery rate for the analysis of heavy metals in packaging-grade paper. The open digestion system using Kjeldahl apparatus and the closed digestion system using microwave oven for decomposing the organic materials in paper were compared. In both open and closed digestion method, the combination of nitric acid, hydrochloric acid and hydrogen peroxide showed higher recovery rate than using only nitric acid alone because the presence of Cl- ions in hydrochloric acid stabilizes ligand formation with metal ions. KOCC was observed to have the highest heavy metal content among the recycled paper samples. The heavy metal contents decomposed with the closed digestion system were relatively higher than with open digestion system.

To restore image degraded by motion blur and additive noise, it is very difficult. In conventional restoration method, regularization is usually applied to all over the image without considering the local characteristics of image. As a result, ringing artifacts appear in edge regions and the noise amplification is introduced in flat regions. To solve this problem we propose an adaptive restoration method using directional regularization operator considering edges and the regularization operator with no direction for flat regions. We verified that the proposed method showed better results in the resolution. As a result it showed visually better image and improved better ISNR further than the conventional methods.

토양수분은 수문 분석에 있어 매우 중요한 인자 중 하나이며 최근 기후변화로 인한 가뭄, 홍수 및 산불발생과 같은 물 관련 재해 발생에 직 간접적으로 영향을 미치기 때문에 지표 토양수분산정은 매우 중요하다. Sentinel-1 SAR(Synthetic Aperture Radar)는 능동형 위성으로 10m의 공간해상도로 제공되기 때문에 기존의 토양수분 전용위성인 SMOS(Soil Moisure and Ocean Salinity), SMAP(Soil Moisture Active Passive) 및 GCOM-W1(Global Change Observation Mission Water) 등 다르게 고해상도 토양수분 산정이 가능하다. 그러나 Sentinel-1 SAR 센서에서는 고해상도 지표 관측 이미지 자료만 제공하며, 토양수분 자료를 직접적으로 제공하지 않는다. 따라서 본 연구에서는 2018년도 Sentinel-1 A/B IW(Interferometric Wide swath) 모드의 VH(Vertical Transmit - Horizontal Receive) 편파 영상과 Sentinel-1 SAR 위성자료 전처리 도구인 SNAP(Sentinel Application Platform)을 이용하여 후방산란계수를 산정하였으며, 산정된 후 방산란계수와 농촌진흥청에서 제공하는 65개 지점의 실측 TDR(Time Domain Reflectrometry) 토양수분의 관계를 이용하여 회귀모형을 도출 및 토양수분 공간분포를 산정하였다. 비록 불확실성은 어느정도 발생 하였으나, 전체적으로 TDR 관측값과 $10m{\times}10m$ 해상도의 Sentinel-1 SAR 기반 토양수분이 일치하는 경향을 보였다. 본 연구 결과는 수문, 농업, 산림, 재해 등 다양한 분야에 활용될 수 있을 것으로 판단된다.

In this study, efficiency of pre-treatment of turbid seawater was measured where micro-air bubbles were used to remove particles in seawater after input of natural coagulant PGA. Artificial seawater was prepared having the intended trubidity using marine sediments and microalgae. 73.7% of turbidity removal was achieved when 0.5g/L of $AlCl_3{\cdot}6H_2O$ was added in the artificial seawater, but 92.4% of turbidity removal was observed when 0.05g/L of PGA was added in the artificial seawater containing microalgae. In addition, much greater turbidity removal was achieved for microalage than sediments. For both cases, input of 0.1g/L PGA and following additional input of micro-air bubbles for 5 seconds resulted in the maximum removal efficiency where reaction time of coagulation was 1 min and flotation by micro-air bubbles was 10 min. From this study, we concluded that micro-air floation after coagulation could be a possible economical pre-treatment method for highly turbid seawater.

Our Korean cuisine, due to growing interests in Korean culture along with outstanding performance of K-pop stars, is attracting worldly attention. As the worldly food pursuit tendency is changing from"fast food" to "slow food", preference for our Korean cuisine, which is well-known for its healthiness, is growing. However, our Korean cuisine, in terms of the world citizen's preference, as receiving evaluation for being lacking behind of Sushi of Japan, Dimsum of China, pizza and pasta of Italy, rice noodle of Vietnam, even to Indonesian and Middle-East foods, has not been achieving drastic advancements despite the cosmopolitan's attention. The previous studies were suggesting that, failure of a localization strategy that changes our traditional taste and aroma adaptive to foreigners' preference, is a cause for this. This study, through case studies of Korean food businesses in the US which have achieved a success through localization strategy, attempts to propose the following global entrepreneurial strategy of Koran food at the US dining out market. As a global entrepreneurial strategy for success, we propose, first a sales strategy not for Koreans but for local people as main customers, second a customization strategy which is not our traditional way but that meets local standard, and finally a committed entrepreneurship.

한국에서의 경찰제도는 국가경찰의 형태로 운영되어와 획일적이고 중앙집중식의 경찰활동에 대한 거부감이 전반적으로 있어왔다. 그러나 지역주민의 의사에 따른 자율규율에 의한 다원적 민주주의를 실현하고 국민의 기본권을 실질적으로 보장하기 위하여 지난 1995년 지방자치단체의 장과 지방의회 의원의 동시선거가 시행되어 온 이래 10여년이 흘렀다. 그러나 지방자치제도가 시행되기 이전부터 자치경찰제도에 대한 논의는 지속적으로 이루어져 왔다. 자치경찰제에 있어서 주요쟁점의 핵심사항은 자치경찰제를 도입하는 것의 득실관계라고 볼 것인데 이는 관점과 어느 측면에 중점을 둘 것인가에 따라 다르게 나타나게 된다. 지방자치의 존재 이유 중에는 주민 복지적 차원에서 주민의 안전보호가 중요한 부분을 차지하고 있다. 특히 자치경찰제는 수사권독립과 함께 지난 몇 대에 걸친 각 대통령의 선거공약이었기 때문에 노무현 정부 출범 이후 정부는 지방분권차원에서 정부혁신지방분권위원회에서 여러 가지 검토를 해 온 바 있다. 2004년 1월에 정부혁신지방분권위원회의 지방 분권과제 주요과제로 자치경찰제 방안을 검토하기 위해 위원, 관계 공무원 10명으로 자치경찰 T/F를 구성하여 운영한 이 후 자치경찰제 도입방안에 대하여 경찰정과 실시 단위 및 수행 사무 등 주요 쟁점에 대해 협의하면서 실천 가능한 방안을 마련하기 위해서 스페인, 프랑스, 이태리, 그리스 자치경찰기관을 현지 방문하여 외국 자치경찰 제도를 조사한 후 2004년 9월 중순에 자치경찰(안)을 발표하였다. 이 안은 크게 경찰을 사법경찰과 행정경찰로 구분하는 개념 하에 최초로 나온 자치경찰제에 대한 구체적 시행 안이라는 점에서 그 의의를 찾을 수 있을 것이나 지금까지의 기대수준에 과연 부응하는 안이 될 수 있을 것인가에 대한 의문이 제기되고 있다. 동 사안은 2005년 하반기에 시범적으로 시행하고 민선 4기 자치단체장이 출범하는 2006년 하반기에 본격적으로 시행될 것으로 발표하고 발표와 동시에 정부혁신지방분권위원회에서는 본 자치경찰제 기본방향과 법안제정의 원칙과 구체적인 내용에 대한 토론회를 개최하는 등 다양한 홍보를 하였으나 여러 가지 문제점으로 인하여 아직 시행되지 못하고 있다. 따라서 과연 이 안이 한국에서의 자치경찰제 시행에 효과적인 안인가 그렇지 않으면 대선공약을 지키기 위한 일종의 정치적 고려를 한 졸속적인 안이 아닌가에 대한 논란이 제기되고 있다. 지금까지 한국에서는 자치경찰에 대한 많은 토의가 있어 왔으나 이번에 제하고 있고 현재 지방자치단체에서 시행하고 있는 기존 법집행방식과 거의 차이가 없는 상태시된 안은 적어도 지금까지 논의되어왔던 제도와는 매우 생소한 자치경찰 제도를 근간으로 에서 ‘무늬만 자치경찰’ 이라는 비판이 일각에서 제기되고 있는 실정이다. 현재 자치단체에서 시행하고 있는 행정 경찰적 기능을 다소 보완하고 제복착용과 조직을 하나 더 만든 정도가 아닌가 하는 정도이다. 그러므로 본 연구에서는 정부혁신지방분권위원회에서 제시한 자치경찰제도(안)을 중심으로 자치경찰제도 운용의 목적 충족과 실질적인 효과의 측면에서 분석하고 바람직한 자치경찰제도의 운용에 대해 살펴본다.

Purpose - This study analyzes the effects of types of leadership on the employees of Italian restaurants, its efficacy, and organizational citizenship behavior, utilizing a causal assessment model. In this study, independent variables such as the type of leadership perceived in the manager or chef by an Italian restaurant's employees, and its efficacy were parameters, and the organizational citizenship behavior and organizational effectiveness were the variables representing the results in the hypothesis. The study aimed to draw implications by verifying the leadership via efficacy and the impact on organizational citizenship behavior of Italian restaurants. Research design, data, methodology - For the purpose of this analysis, specific questionnaire items were configured according to the theory and efficacy of the study. From a questionnaire used in organizational citizenship behavior comprising 22 questions, six were modified to suit the research purpose of this study. The configured questionnaire comprised 5 parts and 40 items. A Likert (Likert) 5-point scale was utilized to measure responses to the questionnaire items from the employees of an Italian restaurant in Seoul who participated in the survey. For data collection, 400 questionnaires were distributed, and 344 collected. Factor analysis and reliability verification were conducted using SPSS18.0 and AMOS18.0. A covariance structure analysis was conducted to test the research hypotheses. Results - Based on the results of the analyses, the summary and suggested implications of the research are as follows: The covariance structure analysis used to analyze the kind of effect transformational and transactional leadership styles in Italian restaurant employees had on self-efficacy, group-efficacy, and organizational citizenship behavior, indicated that among the characteristics of transformational leadership (such as, idealized influence, inspirational motivation, individual consideration, and intellectual stimulation), idealized influence and individual consideration had a positive influence on self-efficacy. Idealized influence, individual consideration, conditional reward, and management by exception also positively influenced self-efficacy and altruistic and conscientious behavior (organizational citizenship behavior). Conclusions - Results suggest that with regard to self-efficacy and group efficacy, managers in different departments and chefs should provide team members with a vision for the future, increase their confidence in their abilities, and build their trust in the organization. By evaluating employee performance and experiences, management can demonstrate leadership and encourage organizational citizenship behavior through enjoyable, voluntary participation. Transformational and transactional leadership is effective in group processes that include social-exchange relationships, self-efficacy and group efficacy, and organizational citizenship behavior. However, as this research study utilizes only self-reported data, it has several limitations, such as a vulnerability of errors caused by the various experiment types. A significant limitation of this study is the lack of potential for the duplication of results. The covariance structure analysis, however, provides complementation to limit the impact of errors from self-reporting studies. A future study can extend this research by utilizing different data collection methods.

The study sought ways to promote the global recognition of Korean food items. The Korean cuisine is one of the healthiest and well-balanced foods in the world. There are world-wide sauces in the United States, China, Japan, Thailand, Vietnam and Cambodia, Singapore, Indonesia, India, Australia, British, France and Italy. The above mentioned countries have good sauces and marketing strategies. In contrast to those countries, the internalization of Korean-style sauce has not yet been carried out. In this study, globalization plans for Korean cuisine through Korean-style sauces are divided as follows: promotion of the existing Korean-style sauces such as soybean sauce, Gochujang, Doenjang and Ssamjang, to chefs in foreign countries; development of derivative sauces, based on Gochujang, Doenjang, and Ssamjang; overseas promotion of Korean-style sauces through foreign chefs in Korea; and overseas promotion of the existing Korean-style sauces. Development of indigenous sauces by Korean food manufacturers and processors is one route in the promotion of Korean cuisine. Korean franchising restaurants could also aid in export of Korean food items. The food manufacturing/processing sectors must work in concert with the Korean government to globalize the Korean cuisine. The government should play a leading role in fostering star chefs, holding Korean cuisine seminars along with promotional efforts in foreign countries and foreign cooking schools (such as the 'Taste Korea' campaign).

Without a solid marketing system in placed, the fashion industry cannot flourish on out-standing design or technology alone. Even though the significance of collecting and analyzing information, merchandising, and retail distribution is recognized, these functions are not firmly rooted or prevalent in our industry. In contrast, Italy which possesses similar demographic traits such as the lack of natural resources and other physical factors has succeed-ed in globalizing its fashion market by responding swiftly and exercising flexiblity to its constantly changing consumer demand. This in turn has earned Italy the competitive edge in the global fashion arena. Italy's unique management skills and operation know-how, along with successful market strategies come into play in bringing competitiveness to Italy's fashion market. Firstly, smaller companies with ability to adopt swiftly to the ever changing market. Secondly, fashion friendly social environment. Thirdly, niche marketing through highly specialized system and differentiation. Fourthly, timeless innovation through intense corporate competition. Lastly, establishment of foundations to support the industry through diverse networking. The alone building blocks have formed a basis for erecting an unparalleled market with a reputation for excellence in design and quality in the global fashion world. This study has examined how Italy's fashion industry has evolved from an underdeveloped textile business into a cutting edge fashion in-dustry. Italy's unique business processes and practices were studied to come up with a collection and merchandising ideas in a niche market. By selecting this venue we are able to continuously grow and develop in a market with diverse consumer needs. To analyze the Italian fashion market, data from 3 institutions were utilized, namely, CIT-ER which has provided consumer trends and sales analysis, SITA,a data service provided statistics from the textile and apparel businesses, and NBI has also furnished valuable data. Italian consumer preference, buying behavior, consumer profile, retail channels and other related data from the above institutions has formed a backbone for market segmentation and target markets, and as a result, we were able to zero in on the type of consumer, produce, pricing and retail channels for our womenswear. Going forward the direction is to elevate product image and pretige, and create syn-ergy between related industries, and at the same note, in order to develop internationally recognized brands such as Max Mara and Benetton. Certain elements such as the specialization of the fashion industry, alon-g with fashion-related data base and systems support, and most importantly experts with acute fashion sense and capacity to analyze pertinent data are in need. I firmly believe that we can achieve Italy's level in the fashion market with support from the government and unrelenting effort within the industry itself, and hope that this report can prove to be useful.

Waste lubricating oil(WLO)s have been recycled as energy source through direct fuel in cement kilns and fossil power plants, or as fuel oils, or re-refined lubricating base oils. In our country, they have been recycled as low grade fuel oil through chemical treatment process. In 2003, extended producer responsibility (EPR) system was adopted from deposit system on sale of lubricating oils in order to promote their recycleing rate. However, our recycling rate of WLOs have been stagnant(below 70%) for last 5 years. And there has been no research work on recycling of WLOs as re-refined base oil until now in this country. Stabilization technology of thermally cracked oils to reduce tar and malodor and to improve their color for production of high grade fuel oil, and a novel process production of high grade re-refined lubricating base oil from WLOs have been developed and commercialized recently in Canada and U.S.A., respectively. Several countries like Australia, Italy, Germany and U.S.A., etc. are encouraging recycling companies to recycle WLOs as re-refined lubricating oil by giving greater subsidies or benefits compared to other recycling methods. They also adopt a policy to purchase re-refined lubricating oil preferentially in the federal or local governments and to recommend consumers to purchase it willingly. Based on the facts that several advanced countries have adopted a policy to recycle WLOs as re-refined base oil for saving of petroleum resource and reduction of environmental pollution, it is right time to be considered that our present policy for recycling of WLOs should be reevaluated and the new policy of their environmental-friendly and sustainable recycling should be established.
