Purpose - This study is to analyze the monetary indicators and the key macroeconomic indicators and to assess the effectiveness of state regulation on its basis. The analysis of monetary aggregates of Russian Federation, CIS, the countries of leading countries of North-East Asia at the present stage of development. Research design and methodology - The volume of data on Russia was analyzed from the 1995 to the 2018. The data from the 1950 to the 2019 were estimated on China. The data from the 1980 to the 2018 were estimated on Japan. On South Korea - since the 1960 to the 2018. On Republic of Belarus - since the 2003 to the 2018. On Tajikistan - from the 2008 to 2017. On Kazakhstan - from the 1994 to the 2018. On Kyrgyzstan - from the 2002 to the 2018. On Armenia - from the 2003 to the 2018. Results - Hypothesis 1: In Russian Federation, the monetary stock has a stable tendency to grow. The volume of money stock of Russia and the analyzed countries is much determined by external debt, GDP, the export, the import, and the international reserves. Hypothesis 2: The growth of money supply does not always give a positive effect in the development of the country, as well as a significant increase in the amount of money stock does not always lead to negative consequences. The monetary stock should be commensurate with the macroeconomic indicators of the state. Conclusions - The growth of the monetary stock does not always give a positive effect in the development of the country, as well as a significant increase in the amount of monetary stock not always lead to negative consequences.

The Korean high-speed rail (HSR) began its commercial service in 2004. This service has been created significant changes in the system of intercity passenger travels of Korea. However, the actual ridership was approximately half of the estimated one in the planning stage. In this background, this paper presents the difference between the stated preference (SP) before the HSR service and the revealed preference (RP) after it using the intercity travel mode choice models. Several meaningful differences are found in terms of the factors affecting the travel mode choice, the estimation results of model, the monetary values of time, and elasticities. While the access/egress travel time of high-speed rail is less important than in-vehicle travel time in the SP sample, they have same weight in the RP sample. Also the RP models show that the probability of choosing HSR can be decreased by the increase of the number of vehicles in household contrary to the results from the SP models. The monetary values of travel time are relatively high and the direct and cross elasticities in response to changes in level-of-service of HSR are relatively low in the RP sample. This Korean case is expected to offer referable material for preparing high-speed rail services in other countries by showing the difference between the SP and RP before/after the actual service, identifying the importance of access/egress travel time and lower direct elasticities of HSR demand.

This study examined the effects of prompts, environmental alteration, and feedback on reduction of food wastes. The study was conducted at a student restaurant at a university. Subjects in this study were college students, faculty members and administrative staffs at the university. An A-BC-BCD-BC within subject design was employed. After baseline phase(A), prompts and environmental alteration were manipulated in the second phase(BC). In the next phase(BCD), feedback was added in addition to the prompts and environmental alteration. In the last phase(B), all the treatments except environmental alteration were withdrawn. The dependent variables n cluded (1) total weight of food waste per day, (2), the weight of food waster per person, (3) the ratio of food waste to total food served per day, (4) total amount of monetary value for food waste to total food served per day. The results indicated that prompts and environmental alteration were affective in reducing food wastes. Thus, measures of all the dependent variables decreased when environmental alteration and prompts were manupulated. However, when feedbacks were added to prompts and environmental alteration, the additional effect of feedback was not observed. The implications and limitations of these findings were discussed and the directions of future studies were also proposed.

The object of this study is the development of a measuring framework for supply chain flexibility. Prior to treat supply chain flexibility, time flexibility, quantity flexibility, and cash-flow flexibility for each company are newly suggested. Especially, all developed measures can deal with the monetary point of view through various cost functions. Then weights of time flexibility, quantity flexibility, cash-flow flexibility are determined to find the effect of the level of flexibility in the supply chain. This is based on the relationship between the ratio of profit to revenue and value of three developed flexibility measures. To find the level of weight for each flexibility measure, neural network theory is used. Then the forecasting of the ratio of profit to revenue for all companies in the next period can be available. Therefore, all companies in the supply chain can control their operating processes to improve flexibility.

This paper examines the interactions between financial conditions and business cycles in Mongolia, a small open economy, heavily depending on commodity exports. We construct two financial conditions indexes based on the reduced form IS model and the vector autoregression (VAR) model as surveillance tools to quantify the degree of the financial conditions. We find that real short-term interest rate and real effective exchange rate gap get a higher weight in the FCIs. Both business and financial cycles are often more pronounced in Mongolia, and financial condition is dependent of the financial and monetary policies in place. The analysis of the predictive power of the FCIs for business cycles shows that they have predictive information for the near-term economic activities. FCIs are also helpful in signaling inflation turning points.

IMF 외환위기 이후 기업의 주기적인 구조조정과 최근 경기 불황의 지속에 따른 명예퇴직, 조기퇴직이 증가하고, 고용 없는 경제성장으로 기업의 신규채용이 증가하지 않는다. 본 연구는 이러한 창업시장이 확대되는 사회적, 경제적 환경과 프랜차이즈 산업의 장 단점 및 산업환경에 따른 기회와 위기에 주목하여 외식프랜차이즈를 중심으로 SWOT요인의 상대적 중요도와 우선순위를 제안하고자 한다. 연구방법으로는 SWOT요인들의 중요도를 분석하기 위해 AHP분석과 ANP분석을 실시하였으며 호환성에 문제가 없어 AHP 분석 결과를 활용하여 중요도 분석을 하였다. 분석결과 첫째, SWOT 분석에서 내부적 요인 중 강점요인을 약점요인보다 중요하게 생각하고 있으며 외부적 요인 중 기회요인을 위기요인보다 중요하게 생각하고 있는 것으로 나타났다. 이는 국내 외식프랜차이즈 사업이 갖는 약점요인과 위기요인이 있긴 하지만 이러한 부정적인 요인보다는 강점요인과 기회요이 갖는 긍정적인 점을 더 중요하게 판단하여 국내 외식프랜차이즈의 전체적인 성장 가능성을 높이 평가한 결과라 할 것이다. 둘째, 강점요인 중에서는 업체그룹은 검증된 비즈니스모델 사용으로 사업안정화(S3)가 가장 중요도가 높았으며 전문가그룹은 가맹본부의 표준화된 제품(서비스) 및 경영지원(S2)이 가장 중요도가 높았다. 셋째, 약점요인 중에는 가맹본부와의 불리한 지위에서 협상 및 해결(W3)과 계약기간 내 계약파기 어려움과 파기 시 막대한 손실발생(W4)의 중요도 합계가 60%에 이른다. 넷째, 기회요인 중에서는 라이프 스타일, 가치관, 소비의식 구조의 변화(O3)가 압도적으로 중요하게 나왔다. 다섯째, 위기요인 중에서는 소비시장이 다양화에 따른 고객의 욕구변화(T1)를 가장 중요하게 생각하는 것으로 나타났다. 향후 다양하게 변할 소비자의 욕구를 어떻게 만족시킬 것인가가 국내 외식프랜차이즈의 위기를 극복하는 가장 중요한 요인임을 반증하고 있다 할 것이다.

세계금융위기의 근본적인 원인은 시장과 제도의 괴리에서 나오는 '제도의 실패'라고 할 수 있다. 특히 현재의 국제통화제도는 무제도(non-system)나 다름없다고 할 수 있다. 현재 당면하고 있는 국제통화제도의 문제점들을 볼 때 개편 방향의 핵심은 (1) 수요 측면에서는 과대한 외환보유고를 축적하려는 인센티브를 어떻게 줄일 수 있을 것인가 하는 것이며, (2) 공급 측면에서는 현재 미국 달러화에 주로 의존하고 있는 제도를 탈피, 보다 다양한 국제통화 혹은 대체적 외화준비자산(SDR을 포함하여)으로 전환해 나가거나 혹은 보다 근본적인 개혁방안으로서 새로운 세계통화(global reserve currency)를 창출하는 것이다. 그리고 (3) 이러한 변화를 뒷받침 하기 위해 필요한 기구적 개편, 특히 IMF의 개혁을 추진하는 것이다. 이러한 개편은 현실적 국제역학관계로 볼 때 오직 점진적으로 일어날 수 있는 것이다. 따라서 현재 세계경제의 안정적 성장을 위해 중요한 것은 이러한 개편을 점진적으로 추진함과 동시에 주요국 간의 거시경제정책공조를 이뤄 나가는 것이다. 이러한 과정을 원활히 해나가기 위해서는 효율적인 세계경제 지배구조를 갖추는 것이 필수적이다. 세계금융위기 이후 출범한 G20 정상회의가 효율적인 협의체가 되기 위해서는 의사결정이 원활히 이루어질 수 있는 방안과 장치를 세워나갈 필요가 있다. 사무국(secretariat) 혹은 그와 유사한 기능을 행사할 수 있는 조직의 설립과 위원회제도 같은 것을 활용할 필요가 있을 것으로 보인다.

The purpose of this study was to : (a) examine diabetic patients' sensory evaluation and food preferences, (b) analyze the portion sizes & plate wastes, (c) investigate the factors affecting plate wastes, and (d) determine the nutritional & mometary values of the plate wastes. A questionnaire for determining food preference and sensory evaluation was developed. Thirty-three diabetic patients who were hospitalized in Sanggye Paik hospital in Seoul were studied. Serving sizes and plate wastes were weighed by using an electric scale, and the CAN-Pro program was used to evaluate the nutritional value or the food consumed. The data were analyzed using the SAS package program for descriptive analysis, t-test, ANOVA, and the Pearson correlation. Using a five-point Likeu-type scale, the temperature s[ore ranged from 3.1 to 3.3 (1 : very poor, 5 : excellent), the preference store was 3.0-3.2 (1 : very dislike, 5:very like), the taste score was 2.9-3.2 (1 : very poor, 5 : excellent), and the amount of food served score was 2.8-3.0 (1 : too little, 5 : too much). Serving sizes were considered insufficient by patients because most of the DM diet was low in calories. Average plate waste for the DM diet was 26.2% of the total served, by weight, and was lower than that for patients consuming a normal diet, which was 30.3%, found in previous research. Those subjects who had been previously hospitalized and who wished to participate in a campaign for food waste reduction produced less plate waste than other groups (p<.05). Plate wastes of the DM diet were negatively correlated with taste, temperature, and preference, and were positively correlated with the amount served: however, these results were not statistically significant. It was found that diabetic patients consumed adequate levels of energy, protein, Ca, Fe, Vitamin B$_1$, Vitamin B$_2$, and niacin, but inadequate levels of Phosphorus, Vitamin A and Vitamin C. The plate wastes were calculated to be 26.2% of the total cost (￦ 3,489), which is ￦9l5. This represents a significant wastage of resources from the hospital. The results of this study could assist foodservice managers in both controlling food wastage, and improving the quality of hospital food services.

현대사회의 금전적인 거래는 대부분 온라인상에서 거래되고 있으며, 오프라인상에서도 현금거래 이외에도 카드 및 스마트폰 등으로 거래가 가능하다. 온라인상에서 이루어지는 금전적인 거래의 장점은 구매과정이 간략하고 현찰로 인한 부피증가와 무게 등의 이동성 저하 요인이 사라진다는 점이다. 그러나 온라인 환경은 물리적인 거리에 제약사항이 없으며, 타인에게 개인정보가 노출될 경우 금전적 손실과 직결될 수 있다는 문제가 있다. 물론 대부분의 금융권에서는 금융 사고에 대비한 보안 정책이 운영되고 있기에 별다른 문제는 없다. 본 논문에서는 OTP를 활용하여 고정적인 카드번호, 유효기간, CVC 등을 매회 임의로 변경하는 것으로 암호화된 정보의 탈취 방지 및 간단한 구조로 동작이 가능함을 보이고자 한다.

재식밀도를 달리하여 소향을 공시하고 생육, 수양 및 품질에 미치는 영향을 구명하고자 2개년(1979, 1980)동안 시험한 결과를 요약하면 다음과 같다. 1. 주당 절대 생장양과 액아 발생량은 소식구보다 밀식구에서 적었다. 2. 엽면적은 소식일수록 컸으나 엽면적지수는 밀식구에서 컸으며 단위 엽면적중은 처리간에 차가 인정되지 않았다. 3. 상대생장률은 소식일수록 후기 생육이 계속되었고, 초형은 밀식인 경우에 양분경합으로 상위엽의 전개가 저해되었으나, 수광율은 본, 상엽에서 광합성작용에 충분한 것으로 보였다. 4. 모용수, Total alkaloid 및 Total nitrogen 함량은 밀식구에서 적었고, 세포간극율, Total sugar 함량은 처리간에 차이가 없었다. 5. 수량은 밀식할수록 많아지는 경향이었으며, 품질은 처리간에 차이가 인정되지 않았다. 따라서 16,666주보다 밀식하여도 품질면에서 지장이 없을것으로 생각된다.
