The purpose of this study is to identify the role of each party in relation to the contract farming of cabbage which is taking place under the contract between the local trader of agricultural produce that supplies raw cabbage to company "D," a manufacturer of kimchi, and the cabbage farm where the cabbage is grown, and to describe the changes brought by the contract farming to the agriculture of the contract area. As a result of the study, it was discovered that, while the farming of cabbage in the contract area used to be led by farmers, it is now increasingly being controlled by the local traders of agricultural produce. First, as the key player in the decision-making related to the cabbage farming in the main cabbage producing areas, local traders of agricultural produce are replacing the role of farmers by supervising the entire production process and controlling the overall cabbage farming in the contract area. Second, in the main cabbage producing areas, local traders of agricultural produce are becoming a key farming entity by carrying out functions that are comparable to those of farmers and playing a major role in the second half of the agricultural work at the farms in the contract area. This can be considered as the result of the balance between the demands of the local traders of agricultural produce who need to secure contract volume and manage the quality of their produce and the demands of the farmers in key cabbage producing areas who are facing difficulties due to the increase in the number of elderly farmers and a shortage of manpower.

Purpose: This study assesses the marketing practices and value-added fish products under the Coral Reef Rehabilitation and Management Program (COREMAP) in East Indonesia. Research design, data and methodology: This study gathered qualitative and quantitative data through i) focus group discussions (FGD) with fishers, traders and COREMAP officers, ii) surveys and iii) interviews with fishermen and traders. This study surveyed 714 households (365 in COREMAP and 349 in non-COREMAP) and 33 traders (17 in COREMAP and 16 in non-COREMAP) using structured questionnaires between January and March 2016. This study used Shepherd's Index to estimate the marketing efficiency for each stage of the marketing channel. For value-added fish products, the value is determined by the difference between processed output and the raw product used. Results: Marketing cost in the non-COREMAP area was more efficient than in COREMAP as indicated by lower operational cost and higher selling price. However, no value-added fish products were produced in the non-COREMAP area. This study noted a lower catch in COREMAP area, which implies COREMAP program successfully reduced fishing pressure. Conclusions: This study identified poor infrastructure and the limited market as the major problems in developing value-added fish products in both COREMAP and non-COREMAP area.

System trading is becoming more popular among Korean traders recently. System traders use automatic order systems based on the system generated buy and sell signals. These signals are generated from the predetermined entry and exit rules that were coded by system traders. Most researches on system trading have focused on designing profitable entry and exit rules using technical indicators. However, market conditions, strategy characteristics, and money management also have influences on the profitability of the system trading. Unexpected price deviations from the predetermined trading rules can incur large losses to system traders. Therefore, most professional traders use strategy portfolios rather than only one strategy. Building a good strategy portfolio is important because trading performance depends on strategy portfolios. Despite of the importance of designing strategy portfolio, rule of thumb methods have been used to select trading strategies. In this study, we propose a SVM-based strategy portfolio management system. SVM were introduced by Vapnik and is known to be effective for data mining area. It can build good portfolios within a very short period of time. Since SVM minimizes structural risks, it is best suitable for the futures trading market in which prices do not move exactly the same as the past. Our system trading strategies include moving-average cross system, MACD cross system, trend-following system, buy dips and sell rallies system, DMI system, Keltner channel system, Bollinger Bands system, and Fibonacci system. These strategies are well known and frequently being used by many professional traders. We program these strategies for generating automated system signals for entry and exit. We propose SVM-based strategies selection system and portfolio construction and order routing system. Strategies selection system is a portfolio training system. It generates training data and makes SVM model using optimal portfolio. We make $m{\times}n$ data matrix by dividing KOSPI 200 index futures data with a same period. Optimal strategy portfolio is derived from analyzing each strategy performance. SVM model is generated based on this data and optimal strategy portfolio. We use 80% of the data for training and the remaining 20% is used for testing the strategy. For training, we select two strategies which show the highest profit in the next day. Selection method 1 selects two strategies and method 2 selects maximum two strategies which show profit more than 0.1 point. We use one-against-all method which has fast processing time. We analyse the daily data of KOSPI 200 index futures contracts from January 1990 to November 2011. Price change rates for 50 days are used as SVM input data. The training period is from January 1990 to March 2007 and the test period is from March 2007 to November 2011. We suggest three benchmark strategies portfolio. BM1 holds two contracts of KOSPI 200 index futures for testing period. BM2 is constructed as two strategies which show the largest cumulative profit during 30 days before testing starts. BM3 has two strategies which show best profits during testing period. Trading cost include brokerage commission cost and slippage cost. The proposed strategy portfolio management system shows profit more than double of the benchmark portfolios. BM1 shows 103.44 point profit, BM2 shows 488.61 point profit, and BM3 shows 502.41 point profit after deducting trading cost. The best benchmark is the portfolio of the two best profit strategies during the test period. The proposed system 1 shows 706.22 point profit and proposed system 2 shows 768.95 point profit after deducting trading cost. The equity curves for the entire period show stable pattern. With higher profit, this suggests a good trading direction for system traders. We can make more stable and more profitable portfolios if we add money management module to the system.

As number of cyber traders are growing, the uses of technical analyzing indicators in trading increase as well. Parabolic SAR, which indicates changes of trend in the market, is one of the most used indicators by cyber traders. Especially when a market shows a specific trend, it is very useful. However, this indicator often gives late signals and shows less trustful ones in a stable market. This paper proposes a method that give more conservative signals by a composition of Parabolic SAR and Moving Average. The experiment will compare the earning rates of using only Parabolic SAR strategy and of using a composition strategy of Parabolic SAR and Moving Average.

This paper argues that (1) word-for-word literary translation is not possible; all it does is achieve what Chukovsky characterized as 'imprecise precision' (1984:47), (2) contra to Nida (1969) and others, translation does not just mean translating meaning, and (3) therefore, a translator must negotiate an uneasy but inevitable compromise between accuracy and elegance. To make the translated passage just as pleasing, moving, and cathartic as the original passage as much as possible, a great deal of literary skill is required on the part of the translator. The iniquity of translators is not so much infidelity as infertility to produce an offspring worthy of an heir to the original writer. Translators are not traitors; they are traders, or literary merchants, who trade one form of linguistic unit for another, often meaning for form, or sense for sound, but sometimes form for meaning. A translator then is not a man of treason but is a tradesman.

In the conventional double auction approaches, two basic assumptions are usually applied - (1) each trader has a linear or quasi-linear utility function of price and quantity, (2) buyers as well as sellers have identical utility functions. However, in practice, these assumptions are unrealisitc. Therefore, a flexible and integrated double auction mechanism that can integrate all traders' diverse utility functions is necessary. We propose a double auction mechanism with resource allocation based on nonlinear utility functions, namely a flexible synchronous double auction system where each participant can express a diverse utility function on the price and quantity. In order to optimize the total market utility consists of multiple complex utility functions of traders, our study proposes a genetic algorithm (GA) We show the viability of the proposed mechanism through several simulation experiments.

Many of the theoretical studies have considered herd behavior as a source of the volatility in financial markets, but there have been few empirical studies on the dynamic herding due to the technical difficulty of detecting herd behavior with time-series data. In this context, this paper proposes a new method for measuring time-varying herd behavior based on QR-GARCH model. Using daily data of KOSPI stocks, this paper provides some empirical evidence for strong and volatile herding among traders of stocks of medium firms, and shows that time-varying herd behavior in traders of some stocks has persistent autocorrelation.

Conrad's novels, specifically the Lingard Trilogy-Almayer's Folly, An Outcast of the Islands, and The Rescue-and Lord Jim, set in the Southeast Asian or Malay Archipelago can be considered travel literature that played a significant role in British imperial expansion. Conrad's Malay novels were based not only on his experience in the region during his commercial journey but also on information from earlier travel writings about the Malays and their customs, including James Brooke's journals. The English traders in Conrad's novels, namely Lingard and Jim, were partly modeled on Brooke, the White Rajah, who founded and ruled the English colony on the northwest of Borneo in the 1840s. The white traders in Conrad's novels, who act as enlightened rulers, represent the British commercial expansionism, which was obscured by the phenomenon of the civilizing mission in the late nineteenth century. On the other hand, the colonial official Clifford's tales and novels about British Malaya demonstrate the typical travel accounts of the late nineteenth century that stress the civilizing mission over commercial exploitation. The concept of the enlightening mission was rooted in evolutionary anthropological thinking, which developed as part of the natural history in the early nineteenth century. In fact, the development of natural history, stimulating British expansion in search of commercially exploitable resources and lands, enabled travel writing as the collection of natural knowledge to become a profitable business. In Conrad, the white characters are mainly traders acting as colonial rulers, while in Clifford, they are scientific rulers with their commercial interests rarely apparent. In sum, Conrad's novels reveal that the new imperialism of the civilizing mission is still a commercial one, which disturbs rather than contributes to the imperial expansion-in contrast to other travel literature such as Clifford's.
