Measuring the value of mobile telecommunication services using a choice-based approach

김용재,박민수 대한경영학회 2023 大韓經營學會誌 Vol.36 No.3

Consumer usage patterns in mobile telecommunication services are shifting from simple voice calls to data-centric services through mobile Internet. Broader usage of mobile telecommunication services has increased the value of these services. Thus, it is necessary to investigate the shift in consumer utility value along with changes in usage patterns. The purpose of this study is to objectively analyse the value of mobile telecommunication services to determine the role of mobile telecommunication services in the smartphone era. Specifically, we use a conjoint analysis to estimate the elasticity of demand through a consumer survey. Conjoint analysis measures the impact on consumer choice and calculates the utility of each service attribute. To accomplish this, we classify the types of current mobile telecommunication services into six categories: voice calls and text messages, information services, mobile SNS , mobile shopping and commerce, mobile banking, and entertainment. We then quantify the value of mobile telecommunication services and the surplus from subscribing to a mobile service plan for each use by using data from a conjoint survey. We also find that this value and surplus are larger for relatively new services. The results imply that the value of mobile telecommunication services becomes multifaceted and higher as consumer usage of telecommunication services in everyday life increases significantly. Our results also offer insights into the drivers of telecommunication services with relevant implications.

In the characteristic of the brain malignant, the blood vessels and tumors have the same color and shape, and the boundary distinction is not clear, Therefore, it is difficult to observe the naked eye. Because of the high invasiveness, the risk of recurrence is high. Therefore, complete resection of the tumor is essential. The method for distinguishing the boundary between blood vessels and tumors is a fluorescence contrast method using indocyanine green (ICG), a fluorescence contrast agent. In ICG, the concentration range analysis is very important because the fluorescence expression state varies depending on the concentration. However, since the analysis result of the fluorescence expression condition is insufficient according to the current concentration, this paper proposes by analyzing the initial protocol of the concentration range. 780 nm infrared light was irradiated to the ICG sample to observe the fluorescence expression through a near infrared (NIR) camera. The wavelength is measured by using a spectrum instrument (ocean view) to observe the fluorescence expression wavelength of 811nm. As a result of analyzing the mol concentration according to each sample, the fluorescence expression range was found to be 16.15-0.16M and the optimum fluorescence concentration on the brightest part was found to be 3.23-0.81M.

일본의 개인과징금제도에 관한 소고 —2004년 도입된 증권거래법의 관련 규정을 중심으로—

Japan introduced the civil money penalty system against individuals to the Securities Exchange Act on June of 2004, which was fundamentally modeled on the U.S. Financial Law. The system was effective on April 1 of 2005. Individuals who have been in violation of the most important provisions under the Securities Exchange Act, in particular ones who are in the course of manipulation, insider trading, or non-disclosure of material information, may be subject to severe civil money penalties besides forfeitures, seizures, and criminal penalties. The Japanese Congress overcame lots of hurdles when introducing the new system, such as the most serious issue like a double jeopardy or a due process concern. This paper aims to the introduction of a similar system in Korea, thereby remarkably suppressing securities-related crimes. The japanese reform in the field of the capital market has been applauded and evaluated as a challenging trial and the best practice by other circles. For instance, based on the Securities Act and regulations, the Fair Trading Commission in Japan has studied and pursued more sophisticated and refined civil money system against individuals who are lurking behind corporations or corporate groups but are initiating illegal activities and practices for the anti-competition and the concentration of their economic powers in a relevant market. Constitutional issues including a double jeopardy problem are also the most interesting topic when researching this system. All of these issues will be deeply discussed in the Japanese Context.

This paper purpose make to remove and to easy TBT of smart city related good such as IT, S/W, IOT, Home network between Korea and China. Research methodology is review 2nd data analysis and focus group Interview ( Government officer, Professor and CEO). This paper compare & analyze International rule & system as follow. First, It is to compare & analyze the smart city system, technical regulation, standard, Test & certification procedure and Inspection. Second, it is review electric/electronic Test, certification and calibration. Third, it is analyze MRA between Korea and china, SDoC, Mutual Acceptance of International certification such as ILAC(APLAC) and IEC CB scheme. This paper intends to draw conclusion and make implication as follows. First, we must promote FTA, MRA. Second, we make to remove and to easy TBT by MRA between Korea and China.Although the MRA is a system where all parties that have concluded agreement enjoy the advantage, Korea is under a state of concluding only the stage 1 agreements(exchange test & certification document among countries) with 5 countries such as United States, Canada, Chile, Japan and Vietnam.

The purpose of the present is to investigate the relation of organizational cynicism to organizational justice and OCB(organizational citizenship behavior). Questionnaire data were collected from 265 employees. To test the hypotheses, structural equation model was employed. The model showed adequate fit to the data. Results showed that organizational justice(distributive justice and procedural justice) were negatively related to organizational cynicism. Also, results supported the hypothesized relationship between organizational cynicism and organizational citizenship behavior(OCBIs and OCBOs). And organizational justice indirectly influences OCB through organizational cynicism as expected. Implications are discussed and future research directions are outlined.

하이에크의 화폐경제 이론에 있어서 시제균형에 관한 연구

김용재 한국산업경제학회 2010 산업경제연구 Vol.23 No.4

하이에크가 시제균형의 개념을 발전시키게 된 이유는 기존의 무시간적인 정태이론과 단순한 화폐수량설이 시간에 걸친 연속적 의사결정에 의해 발생되는 현실의 동학적 모습을 잘 보여주지 못한다는 사실 때문이었다. 따라서 하이에크의 화폐경제 모형에 관한 특징을 두 가지 문제로 요약할 수 있다. 첫째, 하이에크가 일관되게 채택한 균형 개념은 시제 균형이었다. 여기서 저축과 투자가 일치한다는 의미의 시제균형은 시제소비선호와 이에 대응되는 시제자원배분이 일치되고 있음을 의미한다. 시간에 따른 생산계획과 소비계획의 조정문제는 자본시장의 이자율 구조를 통해 이루어지는데 가장 단순한 모형은 하이에크의 삼각형이다. 이와 같은 시제자원배분의 문제가 구체적으로는 시간에 걸친 생산구조의 형태문제를 제기하며 이에 대한 기초이론이 뵘바베르크의 자본이론이다. 그리고 하이에크에게 있어서 생산구조의 교란이 경기변동의 핵심문제가 되며 경제위기의 근본적 원인인 생산구조의 축소는 시제소비선호와 일치되지 않는 시제자원배분에 대한 잘못된 의사결정의 결과이다. 둘째, 하이에크는 데이터의 변화 또는 화폐적 변화에 따른 경제주체의 기대들을 어떻게 변화시키는 가하는 문제이다. 그는 데이터의 변화와 화폐적 변화를 명확히 구분하였다. 하이에크는 데이터의 변화에 의한 경우에는 가격기구의 자연스런 자기조정 메커니즘이 작동한다고 가정하였다. 하이에크는 이러한 데이터의 변화에 의한 예측오류들은 시장에서의 가격선호와 이윤동기에 의해 곧바로 드러나게 되며, 이는 체계적인 왜곡을 발생시키지 않을 것이라고 판단하고 있었다. 반변 화폐적 교란에 의한 예측 오류의 발견은 비교적 오랜 시간이 경과하고 경제전반에 걸쳐 오류가 확산된 이후 그 화폐적 요인이 사라지자마자 기존의 기대들은 실패하게 된다. What made Hayek develop the concept of Intertemporal Equilibrium was that existing statistic theories that omitted time-element did not explain the actual dynamic movements caused by successive decision-making over time. Therefore, Hayek defined Intertemporal Equilibrium as equilibriums including the time and expectation, and he also tried to explain the changes in expectations of economic agents caused by changes in data or money, which resulted in the disturbances or shifts in the existing expectation-equilibrium. Firstly, see the problems in the definition of equilibrium including expectations as a method, which import the time element in the economic model. Hayek consistently adopted Intertemporal Equilibrium as an expectation equilibrium. Here Intertemporal Equilibrium as the equality in investment and saving means that intertemporal preferences and the corresponding intertemporal allocation of resources in consistent with each other. The intertemporal preferences and the corresponding intertemporal allocation of resources are coordinated by the structure of interests in capital goods markets. This simple mode is the Hayekian Triangle. here Problem in intertemporal allocation of resources makes a quest for concrete types of the structure of production over time. Therefore, in Hayeks' business cycle theory, the disturbance or changes in the structure of production has been the key problem, and retrenchment of structure of production as the primary cause of the economic crisis will be caused by the inconsistent intertemporal allocation of resources with the intertemporal preference. Secondly, the problem is how the agents' expectations are changed by real disturbances and monetary disturbances. Hayek explicitly made a distinction between the effect of real disturbances and that od monetary disturbances. Hayek suggested that the expectation-errors caused by real disturbances would be discovered sooner or later by the price signals and individual profit-motives, and this will not caused systematic errors. Therefore, Hayek assumed that the natural coordination mechanism of price system would properly operate in case of real disturbance. But Hayek's business cycle theory was a modification of Intertemporal Equilibrium.
