본 연구는 접촉장면에서 발생하는 의사소통 문제의 해결 과정에서 나타나는 조정패턴의 해명을 목적으로 한다. 연구사례로서 목표언어능력이 서로 다른 한국인 일본어학습자 3인을 대상으로 분석을 시도하였다. 언어관리의 관점에서 조정의 주체에 초점을 맞추어 학습자 자신에 의한 수정인 자기조정과 모어화자에 의한 수정인 타자조정으로 나누었다. 먼저 자기조정은 자기유의-자기수정과 타자유의-자기수정으로 나누어진다. 이어서, 타자조정은 자기유의-타자수정과 타자유의-타자수정으로 나누어진다. 이상의 방법으로 3인의 학습자의 3회에 걸친 계속적인 담화에 나타난 자기조정 및 타자조정의 사용양상에 대해 분석한 결과 다음의 3가지가 밝혀졌다. 첫째, 학습초기 단계에서는 타자조정의 사용빈도가 높으나 목표언어능력이 높아짐에 따라, 자기조정의 사용빈도가 높아진다. 둘째, 자기조정은 목표언어능력이 높아짐에 따라 음성이나 문법 항목의 수정보다는 표현내용의 수정이 많아지는 등의 질적인 변화가 나타났다. 셋째, 타자조정 중 자기유의-타자수정은 목표언어능력이 높아짐에 따라 그 사용수가 감소해간다. 또한 타자유의-타자수정은 학습자별 사용수에는 큰 차이가 없었지만, 초기단계 학습자의 경우는 명시적인 수정이 이루어졌다. 한편 목표언어능력이 높은 학습자는 맞장구의 형태로 암시적인 타자수정이 이루어지는 등 사용양상에 있어서 차이가 나타났다.

Film cooling on a curved surface has been studied numerically. The variations of coolant velocity, injection angle, and curvature are described with the wall heat transfer rate. The improved heat transfer is observed for the curved wall. The results are useful for many applications.

Pipe inside clad welding is mainly used to the flow pipe of sub-sea or chemical plant. For the inside clad welding to the medium pipe with the diameter of about 12", TIG welding is frequently applied with filler metal. In this case, the clad welding has the very broad weld area over $10m^2$. And, the non-destructive test (NDT) such as ultrasonic test (UT) or radiographic testing (RT) should be conducted on the broad weld area, and it costs very high due to the time-consuming work. Therefore, the present study investigated the variation of arc voltage to develop the in-line quality monitoring system for the pipe inside TIG cladding. The 4 experimental parameters (current, arc length, wire feed position, and shield gas flow rate) varied to observe the change of arc voltage and to establish the model for the monitoring. The arc voltage was decreased when the wire was fed to the backward eccentric position(over 2mm), and the shield gas flow rate was insufficient under 10L/min. In the case of the backward eccentric position over 2mm, the bead appearance was not good and the dilution ratio was increased due to deep penetration. When the shield gas flow rate was lower than 10L/min, the bead surface was oxidized.

Recently urban farming attracts a lot of interest and attention from the citizens. Increasing demand of the urban farming can be closely associated with values of the urban farming. The objective of this study is to observe the value of urban farming and to look for ways to improvement of value using one of the stated preference methodology called Contingent Valuation Method. Specifically, this study focuses on experience effect and examines urban farming values from experience group and unexperienced group and variability of their willingness to pay (WTP).

The objective of this study is to estimate the economic value of official management and control for invasive insects and diseases in fruits. The direct and indirect effect of this control measure can be the changes in price of fruits and related goods, changes in export volume of domestic fruits, changes in total volume of fruit production, and reduce the risk in food safety. The contingent valuation method with the single-bounded dichotomous choice is employed to estimate each household`s willingness-to-pay (WTP) to maintain official management and control measures. The total number of sample consists 2,050 respondents between the ages of 19-60 years, and the survey is conducted using Web-based survey. The estimated results for mean WTP is 5,443won per month per household. Therefore, the total economic value of official management and control on fruit in Korea is estimated to be approximately 94.4 billion won per month.
