전통적으로 공공 서비스에 대한 만족도 요인을 측정하기 위해 설문조사나 인터뷰 연구가 주를 이뤄 왔다. 민원의 단순 빈도를 떠나 민원에 내포된 감정의 경중까지 고려되지 않아 민원인이 체감하는 민원의 시급성, 고충의 심각 정도를 판단하기 어렵다. 이에 본 연구의 목적은 헤도노미터 단어별 행복도 점수를 활용해 집단민원이 내포하는 부정적 감성수치를 산정하는 방안을 제시하였다. 국민권익위원회의 2021년 지역별 상위 민원 토픽과 연관키워드 데이터를 대상으로 헤도노미터를 적용하여 민원의 주제별 부정적 감성수치를 산출하고, 지역별로 분포를 가시화하였다. 본 연구결과로 도출된 부정적 감성수치를 이용해 민원에 내포된 감정의 경중을 고려하여 민원인이 체감하는 민원의 시급성, 고충의 심각 정도를 판단하는데 도움이 될 수 있을 것으로 기대된다.

Heavenly Kingdom was known for their strict discipline and law as well as their anti-corruption practices and for putting up unconventional ideas to rule its kingdom. They became weak as their leadership was split along with the power struggles that occurred within their kingdom. Heavenly Kingdom's style of dress also ended during this period, but their philosophy continues to influence the style of dress. Taiping rebellion was modern China's biggest internal disturbance which prior studies included political ideals, gender equality and the peasant movement. My research is to associate Heavenly Kingdom's ideas and their dress style by analyzing its relations. Their form of clothing was similar to the Qing Dynasty but the same. They wanted to restore their identity of the Han(漢) while their ideology was oriented in creating a large enough military power to go against the corrupt Qing Dynasty as seen in their military uniform. This research is to analyze about Heavenly Kingdom's ideology with regard to their style of dress but because of their short existence, there are only small remains of artifacts and clothing available which limits this research. This research has to developing further research as I gather more additional data.

Vinalines is actually known as not only one of Vietnam's state-sponsored economic giants but also the largest shipowner by tonnage in Vietnamese shipping industry. Therefore, a question of how to improve business performance of the corporation is always received deep attention by Vietnamese government, specially after the seriously economic scandal of Vinalines in a last few years. Among development strategies, the study focuses on short-term one in which Vinalines is recommended to restructure its own fleet in order to optimize performance of fleet operation and minimize costs while meeting the customer's shipping demand in near future. The first section is of introduction. Via method of statistical data analysis, section 2 brings to readers a panorama about the development profile and the current situation of development of Vinalines. In section 3, the authors use linear programming for setting a cost-minimization model optimizing Vinalines fleet structure based on available statistics and forecast information by Vinalines. The optimization problem is solved by applying AIMMS software in section 4. Finally, some conclusions and proposals by authors for the development of Vinalines are given.

서포트 벡터 기계(Support Vector Machines, SVMs)에서의 일반화 오차의 경계는 훈련점들과 분리 초평면 사이의 최소의 거리에 의존한다. 특히, 소프트 마진 알고리즘은 목표 마진과 slack 벡터의 놈들에 의하여 경계가 결정된다. 이 논문에서는, 자료들에 있어서 잡음들에 의한 오염들을 직접적으로 고려하는 새로운 소프트 마진 알고리즘을 공식화하였다. 그리고, 수치적 예제를 통하여, 제안된 방법과 기존의 소프트 마진 알고리즘을 비교하였다.

압축된 동영상을 이동통신 채널과 같은 다경로 페이딩 채널을 통해서 전송할 때 전송오류에 의해서 전송 신호의 왜곡이 발생한다. 이러한 전송 오류를 줄이기 위한 한 가지 방법으로 오류정정 부호를 사용할 수 있다. 본 논문에서는 전송되는 정보의 단위인 프레임별로 채널의 상태를 예측하고 예측된 정보를 이용하여 RCPC(rate compatible punctured convolutional) 오류정정 부호의 부호화율을 적응적으로 변화시키는 방법을 제안한다. 이를 위하여 시변 페이딩 채널을 모델링하고 채널예측을 위한 3가지 방법을 제안하여 기존의 채널 예측 방법과 비교하고 성능을 분석하였다. 성능평가 결과 제안하는 적응적 오류정정 부호화 기법이 고정 부호화율을 갖는 오류정정 부호화 기법에 비해서 우수한 성능을 보임을 입증하였다.

This study examines the association between governance quality at country level and stock market performance. Specifically, the study investigates the influence of control of corruption, government effectiveness, political stability and absence of violence, rule of law, regulatory quality, and voice and accountability on all-share index of the stock markets of the six Gulf Cooperation Council (GCC) countries. This study is anchored on two theories - the Efficient Market Hypothesis (EMH) and Institutional Theory. The study employs panel data spanning from 2006 to 2017. The findings show that political stability and absence of violence and rule of law exhibit a significant positive impact on stock market performance, while regulatory quality and voice and accountability have a significant, but negative relationship with stock market performance. The results imply that quality of governance in terms of rule of law and political stability devoid of violence have strong impact on stock market returns. Similarly, improved stock market returns are largely dependent on the efficiency of the institutional environment of market as investors are always wary of the inherent risks associated with the uncertainty of the market. This study has crucial policy implications for the government of the GCC countries and stock market participants.

현재, 디지털 시대의 급속 발전과 함께 멀티미디어 관련 영상 장치들이 대중화 되고 있다. 그러나 영상 데이터를 처리하는 과정에서 임펄스 잡음에 의해 영상이 훼손되어 영상 인식이 어렵게 되며, 이러한 영상을 복원하기 위해 활발한 연구가 진행되고 있다. 본 논문에서는 임펄스 잡음환경에서 훼손된 영상을 복원하기 위해 훼손된 화소를 중심으로 방향성과 화소 사이의 공간적 거리에 따라 가중치를 적용하는 영상복원 필터 알고리즘을 제안하였다. 그리고 개선 효과의 객관적 판단 기준으로 PSNR(peak signal to noise ratio)을 사용하여 기존의 방법들과 비교하였다.

This study analyzes and assesses the effect of good governance consisting of accountability, transparency, and participation on the financial performance of Pare-Pare City local government moderated by the basic values of Siri culture in the form of Lempu (honesty), Amaccangeng (intelligence), and Awaraningeng (courage). The population of this research is 200 local government employees (respondents). The results of data analysis showed that accountability and participation variables had no significant effect on the financial performance of the Pare-Pare City local government. However, the transparency variable has an influence on local government financial performance. It is hoped that all these 3 variables (accountability, transparency, and participation) will have a significant effect on local government financial performance. To achieve this, it is necessary to apply cultural values that exist in society so that cultural values can provide greater guidance in the management of regional finances. The results provide a better understanding of the importance of Siri's cultural value in the implementation of public services to the community. With Siri's cultural values in the form of Lempu, Amaccangeng, and Awaraningeng embedded in their behavior, government employees can improve performance and avoid deviant behavior or corruption. The novelty of this research is a form of analysis by using local cultural values (the basic values of Siri culture) as the moderating variable.

International remittances play a crucial role in the economic management of each country, especially in developing countries. Its functions are diverse, including procurement of foreign currency, serving as a cushion for the balance of payments and foreign exchange reserves by reducing the adverse external shocks, driving economic growth, easing the gap between the rich and the poor, and maintaining macroeconomic stability. However, previous studies on remittances have mainly focused on macro-and micro-economic aspects to analyze the determinants. Therefore, this study attempts to identify the determinants of remittances in 122 countries over the past 25 years from macroeconomic and educational aspects as well as institutional qualities. In addition, given the fact that almost all of the world's top 10 recipient countries in terms of GDP and total remittance size are developing countries, developed and developing countries are separated and analyzed for comparison, assuming that there may be a difference between the two groups. Results show that the coefficients of developed and developing countries are different in four areas: Control of Corruption (CC), Rule of Law (RL), Voice and Accountability (VA), and Regulatory Quality (RQ) among the six institutional variables of interest in this study. These results implicate that even the same institutions and policies should be applied and implemented differently depending on the circumstances of each country. In addition, as suggested by the World Bank, policymakers in all countries should double their policy efforts to lower the costs of remittance and improve access to the financial system for immigrants or dispatched workers to ensure a steady inflow of remittances.
