공공임대주택리츠는 임대기간이 만료되면 임차인이 우선 분양전환 할 수 있는 권리를 가지고 있다. 10년 공공임대주택의 분양전환 시점은 임대의무기간 후 공고되지만 공공주택 특별법의 개정으로 임대의무기간의 1/2만 지나면 임대인과 임차인의 합의하에 분양전환 할 수 있게 되었다. 이를 통해 자가 마련을 위한 수요는 많지만 임대사업자는 수익확보가 되지 않는다는 이유로 조기 분양전환에 소극적인 태도를 보이고 있으며, 분양전환가 산정에 있어 임대인과 임차인의 합의점 도출에 어려움이 있다. 또한 공공임대주택이 '리츠' 방식으로 공급되면서 조기분양전환 수익성에 관련된 이해관계자가 증가하여 임대주택의 공공성을 저해하고 공기업과 정부의 불신이 발생할 우려도 있다. 따라서 공공임대주택리츠의 수익성을 확보하고 공익적 목적을 동시에 실현할 수 있는 조기분양전환 적정시점 분석이 필요하다. 본 연구에서는 임차인이 행사할 수 있는 분양전환권을 옵션의 특성으로 본다. 분석 대상인 '공공임대주택리츠'의 특성이 거시경제변수의 영향을 받을 것으로 고려되는 바 거시경제 상황의 변화에 따른 시나리오별 실물옵션 가치를 분석했다. DCF(Discountes Cash Flow) 모형에 의해 조기분양전환 적정시점 확보가 가능하다. 따라서 변수의 변동성을 예측하여 조기분양전환 시점을 고려해야 할 것으로 생각한다.

Objective: The experiments were carried out to measure the effect of multivitamin, acidifier and Azolla on growth performance, profitability and lipid profiles of blood of broiler chickens to produce safe and cost effective broilers. Methods: In experiment 1, 240 day-old Cobb-500 broiler chicks were fed diets; $D_1$ (control), $D_2$ ($D_1$ with 1 mL multivitamin/liter water), $D_3$ ($D_1$ with 1 mL acidifier/liter water), $D_4$ ($D_1$ with 1 mL multivitamin and 2 mL acidifier/liter water) having 3 replications in each, and 20 chicks/replication. In experiment 2, 150 day-old Cobb-500 broiler chicks were fed diets; $T_1$ (control), $T_2$ (5% Azolla in the diet), $T_3$ (7% Azolla in the diet) and $T_4$ ($T_1$ with 1 mL multivitamin and 1 mL acidifier/liter water) having 3 replications in each, and 20 chicks/replication in control, and 10 chicks/replication in the remaining dietary treatment groups for 35 days. Results: In experiment 1, the highest live weight was observed in $D_4$ (p<0.05), however, feed intake was statistically similar between diets (p>0.05). The lowest feed conversion ratio (FCR) (p<0.001) and mortality (p<0.05) were observed in $D_2$ followed by $D_4$, $D_1$, and $D_3$, respectively. There were no significant differences between diets for feed cost and net profit (p>0.05). However, evidently but not significantly, the highest net profit was obtained in $D_2$ followed by $D_4$, $D_1$, and $D_3$, respectively. In experiment 2, the highest live weight (p<0.05) and feed intake (p<0.001) were observed in $T_4$. Mortality (p<0.01), FCR (p<0.01), feed cost (p<0.05) and net profit (p<0.05) were significantly different among diets. Considering net profit, $T_2$ was the best performing dietary group followed by $T_3$, $T_1$, and $T_4$, respectively. The lowest lipid profiles were observed in $D_3$ followed by $D_1$, $D_4$, and $D_2$, respectively (p<0.05). In experiment 2, the lowest total cholesterol, TG, and the highest amount of high density lipoprotein were observed in $T_2$, followed by $T_3$, $T_1$, and $T_4$, respectively (p<0.05). Evidently but not significantly, low density lipoprotein was the highest in $T_2$ followed by $T_3$, $T_4$, and $T_1$, respectively (p>0.05). Conclusion: In conclusion, Azolla and acidifier reduced lipid profiles of broiler chickens. Considering net profit and lipid profiles, 5% Azolla may be the suitable dietary group for producing safe and profitable broilers. However, more studies are needed to confirm this study prior to suggesting using Azolla in the poultry industry.

This study investigated the effects of fermented product from Bacillus subtilis (FPBS) on feed conversion efficiency, fat accumulation and ammonia production in broiler chicks. Sixty female broilers (strain Chunky, 7-day old) were divided into four groups and raised in individual cages. One group was fed a commercial diet without supplementation of FPBS as the control and the other three groups were fed commercial diets containing FPBS, either 0.5, 1.0 or 2.0%, for 21 days from 7 to 28 days of age. Water and feed were given ad libitum. Feed conversion efficiency was significantly improved in chicks supplemented with 0.5 or 1.0% of FPBS as compared with the control (p<0.05). The activities of hepatic acetyl-CoA carboxylase and fatty acid synthetase, and contents of triglyceride and cholesterol in the liver were significantly decreased in treatment groups (p<0.05) as compared with the control group. FPBS had no effect on the concentration of plasma triglyceride, phospholipids and cholesterol. Feeding FPBS at 1 % or 2% levels reduced ammonia gas release (p<0.05). The inclusion of FPBS at 1 % level may be recommended both to improve production efficiency and to reduce air pollution caused by ammonia gas release. For production efficiency to reach maximal profit, the inclusion of FPBS at 0.5% level can be recommended. Feeding FPBS reduced fat accumulation in the liver.

기업의 운전자본관리는 단기재무전략관리 차원에서 접근이 가능하며, 이는 기업의 유동성 및 수익성 등에 영향관계가 있음이 실증되고 있다. 따라서 효율적인 운전자본관리는 기업의 수익성을 증대시킬 수 있을 뿐만 아니라, 유동성 또한 개선시킬 수 있게 된다. 해운기업의 경우 글로벌금융위기와 맞물려 수익성과 유동성에 많은 어려움을 겪었음에도 불구, 운전자본관리와 수익성에 대한 연구는 전무한 상태이다. 이에 본 연구에서는 2004년 이후 46개 해운기업을 대상으로 운전자본관리와 수익성과의 관계를 규명함으로써 단기재무전략 수립에 유용한 정보를 제공하고자 하였다. 연구의 결과 기존연구들과 같이 매입채무기간, 재고기간, 현금주기, 영업주기가 해운기업의 수익성 즉, 매출액 총이익률과 매출액영업이익률을 개선할 수 있는 중요한 요인인 것으로 실증되었다. 특히 매입채무신용기간과 영업주기의 증가는 수익성의 증가를 가져오는 것으로 분석된 반면, 재고기간과 현금주기는 부(-)의 관계를 보여 이들이 줄어들 경우 수익성이 증가하는 것으로 나타났다. 매출채권기간은 일부 모형에서 유의하였으나, 기존 연구들과는 달리 해운기업의 경우 수익성과의 관계를 설명하기에는 한계가 있는 것으로 나타났다.

Following is an idea to utilize the business ethics as one of business administration strategies. Firstly, conversion of perception is needed in the business administration. Neglecting the pursuit of profit, the conventional strategic goal, is not desirable, we need to, however, have a mind that the consumer and environment centered mind is indispensible to the survival and growing of a business ultimately in establishing a strategic goal of diversified environmental changes. Secondly, conversion of the Chief Executive Officer (CEO)'s attitude in business administration is needed. It is necessary for the CEO to have a strong belief that the business ethics is indispensible to the survival and growing of a business by way of fair and logical management. Therefore the business ethics should be improved since the CEO's ethics can be the standard of his business. Thirdly, the business concerned parties should be considered. The realization of business ethics should be done in a certain way so as to protect the benefit of the all concerned parties such as stockholders. employees, consumers, suppliers, competitors, the local community, etc., since a business is an organization that can exists and grows only in the coexistence with its environment and concerned parties. Fourth, the business ethics should be transformed into a business culture through the enlargement of the general principles of and of employees' behavior as a management strategy. Lastly, business ethics should be improved through continuous evaluations to accommodate its environmental change.

This study examined the relationship between working capital management and performance of listed companies Stock Exchange in Tehran. A total of 40 companies from the cement industry for the period 2007 to 2010 of which only 25 were selected for this study had the condition. In order to achieve the objectives, this study surveys the exploration of correlation regression analysis and used the curve obtained, the regression equation. To test the hypothesis, quantitative analysis was used as a method. The results showed a negative relationship between the variables of working capital management and the company's performance and the only variable cash conversion cycle did not show a significant relationship. There is often a negative correlation between the variables studied. This study is based on five assumptions impact of working capital management on corporate profitability is examined. Therefore, the results suggest that the variables in working capital (average collection of receivables, average inventory turnover period, the average net debt and average transaction cycle) and net operating profit is significant negative correlation Net cash conversion cycle and only illustrates the relationship is not significant. Thus, it showed that in debt collection and debt payment period, the turnover of inventory and net trade cycle to reduce the profitability of companies will increase.

Thirty-six yearling (18 bulls, 18 heifers) swamp buffaloes (Bubalus bubalis) with average liveweight $177{\pm}26kg$, were randomly allotted to receive 6 dietary treatments according to a $2{\times}3$ factorial arrangement in a completely randomized design (CRD). Factor A assigned for two types of straw; untreated rice straw (RS) and urea-treated (5%, w/w) rice straw (UTS). Factor B assigned for three ratio of roughage to concentrate (R:C) at 80:20, 50:50 and 20:80. Feeding trial lasted for 9 months during which respective feeds were offered at 3% body weight and adjusted at bi-weekly intervals using corresponding liveweights. Parameters measured under this experiment were feed intake, ruminal fluid for pH, $NH_3-N$, volatile fatty acids (VFA), liveweight change at bi-weekly intervals, carcass characteristics and cost-net profit analysis. It was found that intakes and digestion coefficients of DM, OM, CP except NDF and ADF were improved appreciably when ratio of concentrate increased. The average daily gain (ADG) and feed conversion ratio (FCR) were highest in group fed urea-treated rice straw at R:C levels of 20:80 (551.2 g/d, 10.7 kg/kg) and 50:50 (542.3 g/d, 10.6 kg/kg). It was obvious that FCR was best in the group fed on urea-treated rice straw (13.8 kg/kg) as compared to untreated rice straw fed-group (24 kg/kg). Carcass compositions of buffaloes measured resulted in 48.2 dressing percentage in all treatments offered at R:C levels of 50:50 and 20:80, however, loin eye area were 46.0, 53.6, 50.0 and $54.0cm^2$ for RS and UTS at respective levels of R:C. It was notable that carcass fat content was low which resulted in higher content of lean meat particularly in group fed UTS at 50:50 ratio R:C. Simple cost-net profit analysis was performed, it was found that net profits were obtained as follows 27, 30, -47, 44, 58, 22 $US/hd for respective treatment groups of RS and UTS at respective R:C levels. As shown, the best net profit resulted in group fed UTS at 50:50 R:C level.

The purposes of this study were: 1) to investigate the operational and financial characteristics of contract-managed high school food services in Seoul, 2) to analyze the financial performance of high school food services 3) to develop guidelines for meal pricing and facilities investment costs. From Oct to Nov 2001, questionnaires were mailed to 249 high schools that were managed by contract food service companies. A 40.2％ response rate was recorded. The results of this study were as follows: 1. Student enrollment in high schools run by contract-managed food services was 1,518, with a 68.5％ participation rate in the school lunch program. The average meal price was 2,141 won. 2. Based on the income statement analysis, average total sales were 410,440,504 won and average net profit was 16,098,558 won. 3. The optimum food cost per meal was 1,200-1,300 won per meal, calculating using the methods of conversion factor, RDA (Recommended Daily Allowance), and nutrient exchange unit. 4. Guidelines for meal pricing were developed using the modified actual pricing method based on facilities investment cost, number of meals and food cost. The ratio of labor cost, general management expenses and ordinary profit were adopted from the schools with liability. The food cost, depreciation and interest cost were calculated based on unit meal. 5. The guideline for facilities investment was developed based on the number of meals, meal price and food cost. The guideline included the maximum facilities investment cost paid by the contract food service management company. (Korean J Nutrition 36(5): 528∼535, 2003)

The experiment was conducted with 144 broiler chicks from day-old to 5 weeks of age to investigate the efficacy of a water additive in broiler production. The chicks were randomly distributed into four different treatments namely T1 (control), T2 (water additive as per recommendation level), T3 (25% less than recommendation) and T4 (25% more than recommendation). Body weight of control group was higher in 2nd week of age, but at the end of the experiment additive groups showed higher values compare to control (p<0.05). Body weight gain was increased and feed conversion ratio was improved in the additives groups during the finishing and total period, although feed intake was different among the additive groups (p<0.05). When the hematological parameters were evaluated, packed cell volume and total erythrocytes counts were increased in the additive group that received 25% more than recommendation, and hemoglobin in 25% less than recommendation group. Mean cell volume and mean cell hemoglobin of the additive groups showed lower (p<0.05) values compare to the control, but other parameters were not affected. Sales price and profit were significantly higher in the additive groups compare to the control, although total production cost was increased in the additive groups (p<0.05). All levels of water additive increased profit in comparison with the control but 25% less than recommendation level appeared to be most profitable and cost effective. It also suggests that any additive considered for poultry, must undergo trial for determining efficacy as well as its cost effectiveness for application.
