This study conducted to predict the stock market prices based on the assumption that internet news articles might have an impact and effect on the rise and fall of stock market prices. The internet news articles were tested to evaluate the accuracy by comparing predicted values of the actual stock index and the forecasting models of the companies. This paper collected stock news from the internet, and analyzed and identified the relationship with the stock price index. Since the internet news contents consist mainly of unstructured texts, this study used text mining technique and multiple regression analysis technique to analyze news articles. A company H as a representative automobile manufacturing company was selected, and prediction models for the stock price index of company H was presented. Thus two prediction models for forecasting the upturn and decline of H stock index is derived and presented. Among the two prediction models, the error value of the prediction model ① is low, and so the prediction performance of the model ① is relatively better than that of the prediction model ②. As the further research, if the contents of this study are supplemented by real artificial intelligent investment decision system and applied to real investment, more practical research results will be able to be developed.

According to enhancement of roles and functions of enterprises’ distribution centers, recent trend of distribution centers are specialization and diversification which have generated lots of new distribution center building or expansion of the existing ones and led attention on stock transfer importance in case of distribution center relocation. This thesis is a study for how to reduce stock transfer leadtime in order to minimize business risk and how to increase inventory accuracy when stock ownership is transferred in case of distribution center relocation, and to provide inventory accuracy management methods and inventory in/out management types, detailed definition to evaluate level for inventory accuracy management and pros/cons by inventory in/out management type assuming ‘the higher inventory accuracy before stock transfer, the shorter stock transfer leadtime when distribution center is relocated'. This thesis provides detailed procedure to secure an absolute stock transfer leadtime and process to confirm hugh inventory accuracy by stakeholders which should be sloved by Task Force Team for stock transfer in case of distribution center relocation.

Despite significant research and progress in examining the effects of loyalty programs on consumer behavior and firm performance, it is still unclear the firm value implications of these programs. The main goal of this article is to investigate whether announcements related to the loyalty program introduction affect firm value. In addition, the current research examines the moderating role of program, firm, and market factors in order to present a complete picture. The authors test the hypotheses empirically by conducting an event study of 134 announcements which cover a set of firms in the United States in five industries for 17 years from 2000 to 2016. We find that on average, the introduction of a loyalty program is positively related to firm value. Findings of this study will help managers understand how and under what conditions, they should introduce a loyalty program in order to affect firm value positively.

At the Bank of Korea, capital stock statistics were created by the PIM (perpetual inventory method) with fixed capital formation data. Asset classifications also included 2 categories in residential buildings, 4 non-residential buildings, 14 constructions, 9 transportation equipment, 28 machinery, and 2 intangible fixed assets. It is the Korean government accounting system which is developed much with the field of the national accounts including the valuation, but until 2008 it was consistent with single-entry bookkeeping. Many countries, including Korea, were single-entry bookkeeping, not double-entry bookkeeping which can be aggregated by government accounting standard account. There was no distinction in journaling between revenue and capital expenditure when it was consistent with single-entry bookkeeping. For example, we would like to appropriately divide the past budget accounts and the settlement accounts data that have been spent on dredging into capital expenditure and revenue expenditure. It, then, tries to add the capital expenditure calculated to FCF (fixed capital formation), because revenue expenditure is cost for maintenance etc. This could be a new direction, especially, in the estimation of capital stock by the perpetual inventory method for infrastructure (SOC, social overhead capital). It should also be noted that there are differences not only between capital and income expenditure but also by other factors. How long will this difference be covered by the difference between the ‘new series’ and ‘old series’ methodologies? In addition, there is no large difference between two series by the major asset classification level. If this is treated as a round-off error, this is a problem.

2014년 2월 여객선의 타두재 상단 너트가 풀려 타가 작동하지 않은 사고가 발생하였다. 많은 여객과 화물의 이동을 목적으로 하는 여객선의 조타 장치 사고로 인한 인명사고는 통계에 의하면 2010~2016년 0명이지만 조타장치의 고장으로 선박의 요건인 이동성을 갖추지 못한다면 물살이 거센 해역이나 출입항 선박이 많은 협수로에서는 선박의 조종에 대한 제약으로 인명사고의 비율이 높은 전복 사고나 충돌 사고로 발전할 수 있다. “선박안전법” 및 관련 고시인 “강선의구조기준”에는 타판과 타심재의 체결에 관련된 내용은 기준화 되어 있으나 타 빠짐의 원인이 되는 상부 타두재와 너트의 체결에 대해서는 별도의 법령이 없다. 사고 이후 한국선급은 강선규칙 5편 제7장에 결합방법에 대해 개정을 하였다. 목포항과 주변 섬을 운항하는 여객선 12척에 대한 현장조사 결과 대부분 C형타 2개가 설치된 구조였으며, 체결방법으로는 9척이 용접에 의한 체결 방법을 적용하고 있었고 선박 자체적으로 예방 점검을 위해 체결 개소에 접근하기 어려운 구조로 되어 있었다. 1년에 한 번씩 타를 들어 올리거나 빼내야 하는 여객선의 특성을 고려하여 동종 사고를 방지할 수 있는 방안에 대해서 NAS 3350 시험을 통해 검토하였다.

This research aimed to improve the healthy properties of puffer fish broth, which has been utilized in Korean and Japanese food. Various healthy foods such as garlic, onion, mushroom, and cauliflower were added as ingredients to pufffer fish stock, and the antioxidative activity of each stock was measured by assaying the DPPH and ABTS radical scavenging activities, reducing power and amount of polyphenol. Shiitake was the most effective in increasing the antioxidative activity of puffer fish stock. The high antioxidative activity of shiitake mushroom seems to be correlated with the amount of polyphenol content in puffer fish broth. The antioxidant activities of puffer fish stock increased proportionally with increasing amount of added shiitake, which in turn was due to the increased amount of total polyphenol in the stock.

This study was conducted to investigate the effect of gelatin concentration and storage on color and texture of puffer fish stock jelly. Puffer fish stock jelly was prepared by adding various amounts (2.5~10 percent) of gelatin to puffer fish stock. Color changes of puffer fish sstock jelly were also investigated during storage at 4℃ and 25℃ with varying amount of gelatin (2.5~10.0 percent). Regardless of storage temperature, the L values of puffer fish stock jelly were slightly increased, while a values of the stock jelly were negatively decreased during storage. However, L and negative b values were decreased with increasing gelatin concentration, whereas a values were increased negatively with increasing gelatin concentration. The texture profiles of puffer fish stock jelly such as hardness, springiness, cohesiveness adhesiveness, chewiness and brittleness were determined during storage at 25℃ and 4℃ at various intervals. The hardness, chewiness and brittleness were increased during storage at 25℃ for four days, while those of springiness and cohesiveness were decreased during storage. However, the values of all textural parameters were increased with increasing gelatin concentration in puffer fish stock jelly. Patterns of textural parameters of puffer fish stock jelly stored at 4℃ were practically identical to those stored at 25℃.

This study researched the population of ecological characteristics of the goldeyes rockfish Sebasetes thompsoni sampled by gill net in the Ulleungdo area from February 2013 to February 2014 in order to assess the current stock status and provide scientific advice for management implementation. The instantaneous coefficient of total mortality (Z) was 0.78/year and the survival rate (S) was 0.459. The instantaneous coefficient of natural mortality (M) was 0.461/year. Based on the estimates of Z and M, the instantaneous coefficient of fishing mortality (F) was 0.318/year. The age at first capture (tc) was 4.41/years. Current Yield-per-recruit (YPR) was 30.83 g, and fishing mortality at maximum YPR (Fmax) and fishing mortality corresponding to 10% of the maximum slope in YPR curve (F0.1) were 3.257/year and 0.673/year, respectively. F35% and F40%, indicating fishing mortalities at 35% and 40% of maximum Spawning biomass-per-recruit (SBPR), were 0.619/year and 0.509/year, respectively. Based on the biological reference points, fishing mortality at overfished threshold yield (FOTY) was calculated as 0.509/year. Current SBPR/SBPRMSY was 1.313 above 1.0, which means ‘not overfishe,’ while current F/FOTY was 0.629 below 1.0, which indicates ‘not overfishing.’ In conclusion, the current status of goldeyes rockfish was located in green zone (i.e., not overfished and not overfishing) according to the revised Kobe plot.

A fatigue analysis considering dynamic effects yields a more accurate fatigue life prediction than static fatigue analysis because it considers effects of inertia, flexibility and resonance that occur in the structure up to its natural frequency. However, the dynamic fatigue analysis of bogie frames of the rolling stock is not yet taken into account in the norm EN 13749. Therefore, in order to assure the safety of the rolling stocks, it is important to examine the fatigue analysis of that considering dynamic effects under applied load histories. Moreover, since the bogie frame consists of various welded joints, it is necessary to evaluate fatigue life of that considering welding properties as well as dynamic effects. In this study, under load histories converted from measured acceleration histories, static and dynamic fatigue analysis of the welded bogie frame are performed respectively.

1998년에 국내 주식시장이 전면 개방됨에 따라, 외국인자본이 국내 주식시장에 거대한 투자주체로 등 장하게 되었다. 일반적으로 외국인투자자는 정보비대칭으로 말미암아 국내 주식시장에 대한 투자에 있어 서 열위를 가질 수 있는 동시에, 반대로, 선진화된 분석기법과 투자기법으로 투자수익에 있어서 우위를 보일 수 있다고 연구되고 있다. 본 연구는 국내 주식시장이 전면 개방된 초기의 시점에서 외국인투자자들 은 어떤 투자행태를 보였고, 그들이 보인 투자행태가 국내 기관투자자 및 개인투자자들의 투자행태와 차이점을 보이는지에 대해 고찰하고 있다. 또한, 투자성과에 있어서 우위를 보인다고 연구된 외국인투자자 들의 투자행태를 국내 기관투자자들이 추종했을 것인지에 대해 탐색적 접근을 시도하였다. 이를 위해 주식시장 전면개방의 초기단계로서 1999년의 자료와 일정시간이 흐른 단계로서 2003년의 자료를 통해 투자주체별로 각각 실증하였다. 실증결과에 따르면, 1999년 외국인투자자는 자산규모, 평균 주가와 정(+)의 관계를 나타냈다. 기관투자자는 기업규모, 총자본순이익률과 정(+)의 관계를 보였고, 주당 순이익과는 부(-)의 관계를 보였다. 개인투자자의 경우, 주당순이익과 정(+)의 관계, 기업규모와 총자산순 이익률 및 평균주가와 부(-)의 관계를 보였다. 예상한 바와 같이, 전면개방 초기단계에서 외국인투자자와 기관투자자, 개인투자자는 선호하는 주식의 특성에 있어서 차이점을 드러내었다. 2003년 외국인투자자는 기업규모와 부채비율 및 PBR값과 정(+)의 관계를 나타내었다. 기관투자자의 경우, 기업규모, 평균주가, 배당률, PBR값, 수출비중과 정(+)의 관계, 부채비율, 주당순이익, PER값과는 부(-)의 관계를 보였다. 개인투자자는 기업규모와 PBR값과 부(-)의 관계를 확인하였다. 이를 통해, 일정 시간이 흐른 단계에서 기관투자자가 외국인투자자의 투자행태를 추종하였다고 판단하기는 어려웠고, 따 라서, 개인투자자와 달리 기관투자자들은 외국인투자자의 투자행태를 추종할 것이라 기대한 가설은 지지 되지 않았다.

본 연구는 국제원유시장과 아시아 주식시장(한국, 중국, 일본, 인도, 인도네시아, 필리핀, 말레이시아, 태국, 대만, 싱가포르, 베트남)간의 상관관계를 국면전환 관점에서 분석한다. 이를 위해 유가와 주가지수 간의 시간가 변 상관계수를 DCC-GARCH(1,1) 모형으로 추정하였고, 비선형 시계열 분석기법인 Smooth Transition Regression(STR) 모형을 활용해 구조적 변화의 비선형 특성과 상관관계의 강도를 파악하였다. 2002년 1월부 터 2016년 3월까지의 자료를 토대로 한 분석 결과, 국제유가와 아시아 주가지수간의 상관관계는 시간의 흐름에 따라 그리고 국가별로 상이한 움직임을 나타냈다. 또한 상관관계의 국면간 전환점과 전환속도를 측정하는 모수가 일부 국가에서 유의하게 추정되었다. 이러한 결과는 원유와 아시아 국가 주식으로 포트폴리오를 구성할 경우 상 관계수의 추정과정에서 비선형성과 강도를 고려해야 할 필요가 있음을 시사한다. 이에 본 논문은 방법론적으로 기존의 국제재무 문헌의 확장에 기여하며 주식시장과 원유시장의 관계자들에게도 포트폴리오 구성 및 시장예측과 관련한 실무적 시사점도 제공한다.

Many corporate brands are strongly associated with the person the companies are headed by (Argenti & Druckenmiller, 2004). Attention for corporate psychopaths (CPs), defined as individuals who show psychopathic traits and work successfully in corporations, has been growing lately (Boddy, 2005). Psychopathic traits (e.g. charm, lack of remorse and empathy) can easily be interpreted as leadership characteristics (e.g. charisma and decisiveness) and therefore boost the career of the psychopath allowing him/her to climb up the corporate ladder (Boddy, 2011). Empirical evidence—although limited—supports this assumption. It has been found that CPs more frequently have senior level positions in organizations than junior ones (Boddy, Ladyshewsky, &Galvin, 2010b) and that the chances of finding a psychopath among CEOs is four times higher than in the general population (Bercovici, 2011). A CP in a high level position (e.g. a CEO) can not only be assumed to have the largest leverage on how the company’s resources are deployed, but the way s/he is perceived by others also has a great impact on the company’s image (McGrath, 1995). The willingness to trust an entity is “based on the expectation that the other party will perform a particular action important to the trustor, irrespective of the ability to monitor or control that other party” (Mayer, Davis, & Schoorman, 1995). Therefore, the perception of negative/psychopathic traits in a CEO is of considerable importance to organizations because it influences the CEO’s public image and subsequently the level of trust placed in the top manager. This, in turn, can have far-reaching consequences for the company he works for because an executive’s greatest capital consists in the trust placed in him/her and a company cannot be successful in the long run without the trust from stakeholder groups (Hage, 2012). The perception of psychopathic traits can thus have severe consequences for the company’s attractiveness to its stakeholders. The current research investigates the effects of perceived psychopathy of CEOs for the attractiveness of any form of interaction with the company. Results of a structural equation model based on a survey among 670 participants show that perceived corporate psychopathy negatively influences perceived trust in the CEO. Perceived trust in the CEO, in turn, has a positive effect on perceived attractiveness of products, of shares, and of perceived employer attractiveness. Furthermore, if an individual considers sustainability to be of high importance, the ethical standards concerning sustainable behavior seem to be stricter because the trustor cares about them more than the economic aspects of how the CEO manages the company. Therefore, it was found that attitude toward sustainability moderates the relationship between perceived corporate psychopathy and perceived trust in the CEO.

2011년 개정상법은 재무제표의 작성에 관한 회계규정을 대폭 삭제하 고, 회계의 원칙(상법 제446조의 2)을 신설함으로써 기업회계기준과의 조화를 도모하였다. 그러나 이러한 상법의 개선 노력에도 불구하고, 상법 의 회계규정과 기업회계기준과의 불일치로 인한 문제점에 대하여는 여전 히 기업실무와 학계에서 논의되고 있다. 첫째, 재무제표의 범위 및 명칭과 관련하여 (ⅰ) 기업회계기준과는 달 리, 상법은 외부감사대상 회사의 재무제표에는 이익잉여금처분계산서(또 는 결손금처리계산서)를 포함시키고 있는 반면, 그 밖의 주식회사의 재 무제표에는 현금흐름표와 주석을 포함시키지 않고 있다. 이익잉여금처분 계산서(또는 결손금처리계산서)의 내용은 대부분 자본변동표로 대체될 수 있다는 점을 고려할 때, 이익잉여금처분계산서(또는 결손금처리계산 서)를 외부감사대상 회사의 재무제표의 범위에서 제외하고, 주석으로 공 시하는 것을 허용하는 것이 기업회계실무의 편의상 바람직하다고 본다. 그리고 그 밖의 주식회사에 대하여는 이해관계자에 대한 정확한 재무정 보의 전달을 위하여 주석을 재무제표의 범위에 포함시키는 것이 바람직 하다고 생각된다. (ⅱ) 상법은 연결재무제표의 범위에 대하여는 규정하 지 않고 있지 않은데, 이에 대한 입법이 필요하다고 본다. (ⅲ) 상법상의 대차대조표는 그 명칭을 기업회계기준이나 법인세법 등의 다른 법령과 같이 재무상태표로 개정하는 것이 타당하다고 본다. 둘째, 자본금(액면주식을 발행하는 경우)에 대하여 우리 상법은 발행 주식의 액면총액으로 한다고 규정하고 있는데(상법 제451조 제1항), 한 국채택국제회계기준과 일반기업회계기준에서는 자본금을 보통주자본금과 우선주자본금으로 구분하고 있다. 그리고 우선주자본금의 경우에는 그 성격에 따라 자본과 부채로 구분하여 계상하도록 규정하고 있기 때문에 상법에 규정된 자본금과 기업회계기준에 따른 자본금이 일치하지 않는다 는 문제점이 있다. 그러나 자본금의 회사채권자에 대한 담보기능을 고려 할 때, 자본금의 회계처리에 관하여는 상법의 회계규정이 기업회계기준 에 우선하는 것이 바람직하다고 본다. 셋째, 우리 상법은 주식회사의 보통배당에 관하여 무분별한 이익배당 을 규제하기 위하여 배당가능이익을 산정할 때, 미실현이익을 공제하도록 규정하고 있으나, 자본조정과 전기의 미처분이익잉여금에 대하여는 이익배당을 할 때, 공제하도록 규제하고 있지 않고 있으며, 중간배당을 하는 경우에는 미실현이익을 공제대상에서 제외하고 있다는 문제점이 있 다. 따라서 배당가능이익을 산정할 때에는 자본조정과 전기의 미처분이 익잉여금도 공제하는 것이 타당하다고 보며, 중간배당을 할 때에도 미실 현이익을 공제하도록 규제하는 것이 바람직하다고 본다.

울시 가로수의 79%를 차지하는 은행나무, 메타세콰이어, 느티나무, 양버즘나무를 대상으로 흉고직경 을 이용하여 4개의 상대생장식을 비교하였다. 최적의 상대생장식을 개발하기 위하여 이용된 통계량은 결정계수, 잔차 평균, 절대평균 잔차제곱이다. 이를 통하여 추정된 수종별 상대생장식은 양버즘나무에 서  , 은행나무, 메타세콰이어, 느티나무에서    식이고 결정계수는 0.873이상의 수치를 나타내 어 가로수 탄소저장량 추정에 사용이 적합한 것으로 판단된다. 본 연구에서 개발된 재적식을 이용하여 추정된 서울시 가로수의 주요 4종에 저장된 탄소량은 약 33,760tC이다. 본 연구의 결과로 제시된 서울 시 가로수의 재적식과 탄소저장량은 가로수의 수종별 생장 및 재적정보를 제시하고 도시녹지의 탄소저 장량 평가에 활용이 가능할 것으로 판단된다.

본 연구는 공급자(supplier), 중간공급자(distributor) 그리고 고객(customer)으로 구성된 2 단계 공급사슬에서 퇴화성 제품(deteriorating products)에 대한 중간공급자의 재고모형을 분석하였다. 문제 분석을 위해 공급자는 중간공급자의 수요 증대를 목적으로 중간공급자의 주문 크기에 따라 차별적으로 외상 기간을 허용하고, 최종 고객의 수요는 중간공급자의 재고 수준에 따라 선형적(linearly)으로 증가한다는 가정 하에 모형을 분석하였다. 중간공급자의 이익을 최대화하는 경제적 주문량 결정 방법을 제시하였고, 예제를 통하여 그 해법의 타당성을 보였으며, 민감도 분석을 통하여 퇴화율이 재고정책에 미치는 영향을 분석하였다.

One of the most usual indicators to measure the performance of any inventory policy is the mean physical stock. In general, when estimating the mean physical stock in periodic review inventory systems, approximate approaches are often utilized by practitioners and researchers. The mean physical stock is generally calculated by a simple approximation. Still these simple methods are frequently used to analyze various single stockpoint and multi-echelon inventory systems. However, such a simple approximation can be very inaccurate. This is particularly true for low service levels. Even though exact methods to calculate the mean physical stock have been derived, they are available for specific cases only and computationally not very efficient, and therefore less useful in practice. In literature, approximate approaches, such as the simple, the linear, and Simpson approximations, were derived for the periodic review inventory systems that allow backorders. This paper modifies the approximate approaches for the lost sales case and evaluates the modified approximate approaches. Through computational experiments, average (and maximum) percentage deviations of mean physical stock between the exact method and the modified approximations are compared in the periodic review inventory system with lost sales. The same comparison between the modified and the original approximations are also conducted, in order to examine the performance of modified approximations. The results show that all modified approximations perform well for high service levels, but also that the performance may deteriorate fast with decreasing service level. The modified Simpson approximation is clearly better. In addition, the comparison between the modified and the original approximations in the periodic review inventory system with lost sales shows that the modified approximation outperforms the original approximation.

This study was performed to estimate biomass and to provide management plan through population ecological characteristics, including survival rate, instantaneous coefficient of natural and fishing mortalities, and age at first capture of Flathead grey mullet, Mugil cephalus, in the coastal waters of Yeosu. Survival rate (S) of the flathead grey mullet was 3.671. The instantaneous coefficients of natural mortality (M) and fishing mortality (F) was estimated to be 0.325 /year, 0.962 /year for flathead grey mullet. Also fist capure age of flathead grey mullet was 3.61year. The current biomass of the flathead grey mullet in the study area was estimated to be 19.6 M/T and F0.1 and F40% were estimated 0.340 /year, 0.225 /year. For the stock assessment result, flathead grey mullet was not overfished but overfishing.

The study was carried out to assess the production performances of Japanese quail parent stock raised under open housing system and the study was conducted in a local farm with 2000 Japanese parent stock quail birds (Coturnix coturnix japonica). Observed body weight gain was recorded in each weekend up to 7 weeks of their age; birds gained weight 15.73, 31.45, 47.20, 90.80, 125.27, 153.14 and 175.20 grams, respectively. There have been observed sharp decline of fertility and hatchability of birds with increase of their age. Optimum fertility was recorded at third week and optimum hatchability at fifth week of their age. Average flock uniformity was found 83.68%. The hen day egg production of the flock was recorded 81, 83, 85, 86, 89, 89, 89, 89 and 88% in each weekend, respectively. It may therefore be concluded that Japanese quail parent stock performs well under open housing system in Bangladesh and future study can be taken to better understand their production performances.

Several national control plans have been formulated and carried out to prevent domestic animals from various infectious diseases in Korea. Typical plans include the prevention of diseases by vaccination and the quarantine activities to reduce or cut off the occurrence and transmission. Although such great efforts to prevent diseases every year, difficulties have been experienced in controling transmittable diseases like foot-and-mouth disease and bird influenza. The present study was conducted to investigate the awareness, knowledge, difficulties and routine activities in controling infectious diseases on persons-in-charge of preventive measures in national live stock breeding facilities. A questionnaire survey composed of 81 questions in three categories was carried out on 30 subjects (12 veterinarians and 18 ordinary workers) serving in nine national breeding stock farms. According to the results of the survey analysis, the difficulties and concerns in carrying out preventive measures experienced by the veterinarians and the ordinary workers were similar. Shortage of budgets and manpower was the top ranked concern in performing preventive measures for both the veterinarians and the ordinary workers. Manual or guideline on controling infectious diseases for routine or emergency case were established in all of the facilities, however those were not executed practically in most cases. Instructional training on those manual and controling wild animal to prevent contacting breeding stock were not performed in most facilities surveyed.
