The effectiveness of 100/30, 100/40 and SRSS directional combination rules on the response of asymmetric setback buildings is examined. Because of the irregularity in setback buildings, the maximum seismic response would be correlative with the direction of earthquake. To verify the directional combination rules of mode superposition methods, the time history analyses of setback buildings to real earthquake records are carried out. Example analyses have been used to compare the validty and accuracy of SRSS and percentage methods for frame and dual frame-wall systems.

This paper deals with the application of the genetic algorithm to the technical trading rule of the stock market. MACD(Moving Average Convergence & Divergence) and the Stochastic techniques are widely used technical trading rules in the financial markets. But, it is necessary to determine the parameters of these trading rules in order to use the trading rules. We use the genetic algorithm to obtain the appropriate values of the parameters. We use the daily KOSPI data of eight years during January 1995 and October 2002 as the experimental data. We divide the total experimental period into learning period and testing period. The genetic algorithm determines the values of parameters for the trading rules during the teaming period and we test the performance of the algorithm during the testing period with the determined parameters. Also, we compare the return of the genetic algorithm with the returns of buy-hold strategy and risk-free asset. From the experiment, we can see that the genetic algorithm outperforms the other strategies. Thus, we can conclude that genetic algorithm can be used successfully to the technical trading rule.

본 연구의 목적은 비트코인 선물의 투자 전략으로 기술적 거래 규칙들을 제안하고, 실증 분석을 통해 투자 성과를 분석하는 것이다. 투자 전략은 표준적인 거래 전략인 VMA, TRB, FR, MACD, RSI, BB 등이며, 2017년 12월 18일부터 2021년 3월 31일까지의 비트코인 선물 일별 자료를 이용하였다. 실증 분석 결과, 추세 추종형 거래 규칙들 모두 비교전략인 Buy & Hold 보다 투자 성과가 높게 나타났다. 코스피200 주가지수 선물과의 비교에서는 비트코인 선물 투자 성과가 높게 나타났다. 특히, 비트코인 선물의 투자 성과는 하방 위험을 반영하는 Sortino Ratio에서 큰 폭으로 증가하였다. 본 연구는 비트코인 선물의 표준적인 기술적 거래 규칙들의 투자 성과를 체계적으로 분석한 첫 시도라는 점에서 학술적 의미를 찾을 수 있다. 향후 연구에서는 비트코인 선물의 가격 예측을 위한 딥러닝 모형이나 기계학습 모형의 활용을 통해 투자 성과를 개선할 필요가 있다.

The author presents a simple data-driven intraday technical indicator trading approach based on Genetic Programming (GP) for return forecasting in the Bitcoin market. We use five trend-following technical indicators as input to GP for developing trading rules. Using data on daily Bitcoin historical prices from January 2017 to February 2020, our principal results show that the combination of technical analysis indicators and Artificial Intelligence (AI) techniques, primarily GP, is a potential forecasting tool for Bitcoin prices, even outperforming the buy-and-hold strategy. Sensitivity analysis is employed to adjust the number and values of variables, activation functions, and fitness functions of the GP-based system to verify our approach's robustness.

Purpose: This study examined the importance and satisfaction of consumer's perception of the information delivery format of products and services required and recommended by KS A ISO / IEC Guide 13: 2003 and KS A ISO / IEC Guide 37: 2003. Methods: In this study, the importance and satisfaction of clarity, principles of information transfer, how to use expressions and technical terms, and technical terms, warning signs, and durability were investigated. Results: The t-test analysis of the importance and satisfaction of the Writing Rules of the product user guide showed that all items had statistically significant differences. The importance of the writing rules of the product user guide for the use of the product was in the order of warning signs (4.423), how to use expressions and technical terms (4.215), principles of information transfer (4.163), clarity (3.914), and finally durability (3.851). Conclusion: Among the 'explanation,' 'instruction' and 'warning' functions of the Product User Guide, the consumer uses the manual to identify the inherent dangers and misuse of the product. Besides, since the life of the product is prolonged, the Product User Guide also needs to improve the quality of the cover or paper so that it can use for a long time.

Purpose - The purpose of this study was to expound the packaging framework system(PFS) under international trade rules. Design/methodology/approach - This study analyzed packaging framework system and packaging regulations and technical standards in international regulations and major countries and classified these in some standards Findings - First, the study provides packaging provisions associated with packaging regulations and technical standards (PRTS). Then, the basis of PFS in international trade rules was proposed; it is believed that the PFS was composed of packaging legal system in WTO institutional framework (WTO-PLS), international organization packaging standard system (IO-PSS) and major countries or regions packaging regulatory system (MCR-PRS). Secondly, this paper expounded relations and legal characteristics of the three packaging systems. Finally, This study investigated PRTS coverage under technical barriers to trade (TBT) and Sanitary and Phytosanitary measures (SPS). Research implications or Originality - The regulations associated with PRTS have played a key role in challenges to merchandise trade in international trade. This study has significance in classifying packaging related reticulations into several criteria unlike previous studies. Therefore it is hope that this study can provide a supplementary document for the existing research of PRTS.

아라비아 숫자를 읽을 때 글과 말이 일치하지 않는 문제가 있다. 아라비아 숫자를 읽는 기준이 확실치 않아, 숫자가 놓인 위치, 단위명사, 수의 크기, 구성요소들 간의 결합관계, 문맥 등에 따라 숫자를 다양하게 읽어야 한다. 이 논문에서는 더 읽기 좋은 기술문을 쓰는 관점에서, 수사, 분류사 및 수량 단위명사와 관련한 연구 자료들을 조사하여, 아라비아 숫자 자리에 우리말 숫자를 적어야 하는 여덟 가지 규칙을 정리하였다.

The International Association of Classification Societies(IACS) can trace its original back to the International Conference on Load Lines of 1930 and was established in 1968. Long before the formal foundation of IACS, a number of working parties existed to carry out studies of specific topics concerning technical rules of classification. The general terms of reference of the working groups of IACS are to draft unified rules and regulations between Societies, to study safety standards at the request of the International Maritime Organization(IMO) and to prepare unified interpretations of technical regulations of international conventions. As an associate member since 1975, the Korean Resister of Shipping has been actively attending the meeting of IACS working parties. In this paper, summaries of major agenda of the working parties including history of unified requirements and relevant technical tendencies are explained for the purpose of providing better understanding of the rule development.

본 논문에서는 인지 무선 기술을 기반으로 한 주파수 공동 사용 기술을 적용하는 대역으로 주목을 받고 있는 TVWS 대역에 관하여 국내 기술 기준을 제정할 경우에 기존 서비스 보호, TVBD의 기술적인 요구 사항 및 TV 대역 DB 구축 관점에서 고려하여야할 기술적인 사항들을 제안한다. 제안한 사항들의 기본 개념은 기존 서비스인 DTV 및 무선 마이크를 절대적으로 보호해야 한다는 점을 기반으로 하고 있다. 외국의 기술 규격을 분석한 결과, 영국의 Ofcom 접근 방법은 매번 채널 및 출력 선정 알고리즘을 계산해야 되므로 TV 대역 DB에 상당한 부하가 걸릴 수 있는 반면에 미국의 FCC 접근 방법은 상대적으로 신속한 채널 목록과 송신 출력을 지정해 줄 수 있는 장점이 있음을 알 수 있었다.

This study presents the new dispatching rules of job shop scheduling with auxiliary resource constraint to improve the schedule performance measures related to completion time and due dates. The proposed dispatching rules consider the information of total work remaining and machine utilization to decrease mean flowtime and mean tardiness. The results of computer experiments show that those schedule performances are significantly improved by using the new dispatching rules. The results provide guidance for the researchers and practitioners of auxiliary resource constrained job shop scheduling to decrease mean flowtime and mean tardiness.
