Park, Youjin,Park, Yunjoo 신영어영문학회 2019 신영어영문학 Vol.72 No.-

The purpose of this study is to suggest the design of improved English dialogues as a remedy for the shortcomings of airline cabin English textbooks. For this purpose, a total of 11 dialogues about problems relating to cabin service were analyzed according to the ‘Five Steps in Customer Complaint Recovery.’ As a result, by applying ‘Step 1 Appreciation,’ the cabin crew in the new dialogues became more positive, viewing passengers’ complaints as an opportunity to improve their service. Next, by adding ‘Step 2 Sympathy,’ the crew became more warm-hearted, showing passengers that the crew sincerely cared about them. Lastly, by utilizing ‘Step 3 Promise,’ ‘Step 4 Information or Suggestion,’ and ‘Step 5 Satisfaction Check,’ the crew became more active, eager to resolve any complaints. In conclusion, this paper proposes that if these results are reflected in the relevant textbooks, then pre- and in-service cabin crew will have the opportunity to improve not only their English abilities but also their service professionalism.

Effective contact resistance of zinc-tin oxide-based thin film transistors.

Kang, Youjin,Han, Dongsuk,Park, Jaehyung,Shin, Sora,Choi, Duckkyun,Park, Jongwan American Scientific Publishers 2014 Journal of nanoscience and nanotechnology Vol.14 No.11

<P>We investigated different source/drain (S/D) electrode materials in thin-film transistors (TFTs) based on amorphous zinc-tin oxide (ZTO) semiconductors. The transfer length, channel conductance, and effective contact resistance between the S/D electrodes and the a-ZTO channel layer were examined. Total ON resistance (R(T)), transfer length (L(T)) and effective contact resistance (R(c-eff)) were extracted by the well-known transmission-line method (TLM) using a series of TFTs with different channel lengths. When the width of ZTO channel layer was fixed as 50 μm, the lengths were varying from 10 to 50 μm. The channel layer and S/D electrode were defined by lift-off process and for the S/D electrodes, indium-tin oxide (ITO), Cu, and Mo were used. The resistivity and work function values of electrode materials were considered when selected as candidates for S/D electrodes of ZTO-TFTs. The results showed that the ZTO-TFTs with Mo S/D electrodes had the lowest effective contact resistance indicating that ZTO-TFTs with Mo electrodes have better electrical performance compared to others.</P>

반도체 플라즈마 증착공정장비에서의 효율적인 장비 운영 알고리즘에 관한 연구

박유진(YouJin Park),황하란(HaRan Hwang) 한국생산관리학회 2013 한국생산관리학회지 Vol.24 No.1

Recently, implementation of full automation in semiconductor manufacturing system almost precludes workers from intervening in fabrication processes because the environment of semiconductor manufacturing is rapidly evolving. Generally, various problems such as bottleneck and delay of transfer frequently occur unless the proper operation and control of the equipment is done because semiconductor products are highly dependent on the performance of the manufacturing equipment. Thus, it is very important to manage manufacturing equipment effectively and improve or develop useful operation methods continuously since these problems have a hugh impact on not only semiconductor throughput but manufacturing cost. In this study, in order to enhance throughput of cluster tool-type plasma deposition equipment, we propose three heuristic algorithms which find optimal operation condition with reflecting the mechanical and operational characteristics of the plasma deposition equipment as well as restrictions on operations or processes. It is shown that, out of three heuristic algorithms proposed, the genetic algorithm provides the most favorable equipment operation condition which minimize the cycle time compared to the other algorithms. Also, the algorithms developed in this study can be used as a very critical module of equipment scheduler for the nextgeneration wafer production system. 현재 반도체 제조환경이 다양한 형태로 신속하게 진화됨에 따라 공정의 완전자동화가 이루어짐으로 인해 작업자가 공정에 개입하는 것이 불필요해지고 있다. 일반적으로 생산 장비의 성능에 의존적인 반도체 제품 생산기업에서는 병목현상이나 반송시간 지연 등과 같은 여러 문제들을 효과적으로 해결하기 위한 다양한 운영․관리방법들을 개발하여 적용하고 있다. 특히 이러한 문제들은 반도체 라인의 생산성에 매우 큰 영향을 미칠 뿐만 아니라 제조비용을 막대하게 증가시키므로 장비를 효율적으로 운영․관리하고 꾸준히 개선하는 활동은 매우 중요하다. 따라서 본 연구에서는 대표적인 클러스터 툴 형태의 반도체 공정장비인 플라즈마 증착공정장비의 기계적 특성과 운영 또는 공정상의 제약들을 반영하여 생산성을 향상시키기 위한 세 가지 운영 알고리즘을 제시하고 이들의 성능을 평가하고자 한다. 본 연구에서 제시된 세 가지 운영 알고리즘 중에서, 유전자 알고리즘이 클러스터 툴 형태의 플라즈마 증착공정장비의 생산 사이클 타임 최소화 측면에서 가장 우수한 성능을 보여줌을 알 수 있었다. 이러한 효율적인 운영 알고리즘은 차세대 450mm 반도체 웨이퍼 생산시스템의 장비 스케줄러 운영 모듈로써 사용될 수 있다.

Kim, Youjin,Kim, Kyoung-Mee,Choi, Min Gew,Lee, Jun Ho,Sohn, Tae Sung,Bae, Jae Moon,Kim, Sung,Lee, Su Jin,Kim, Seung Tae,Lee, Jeeyun,Park, Joon Oh,Park, Young Suk,Lim, Ho Yeong,Kang, Won Ki,Park, Se Ho The Korean Gastric Cancer Association 2018 Journal of gastric cancer Vol.18 No.4

Purpose: We aimed to discuss the roles of radiation and chemotherapy as adjuvant treatment in patients with staged IB GC who were enrolled in the adjuvant chemoradiotherapy in stomach tumors (ARTIST) trial. Materials and Methods: Among the 458 patients who were enrolled in the ARTIST trial, 99 had stage IB disease. The patients were randomly assigned to receive either adjuvant chemoradiotherapy with capecitabine plus cisplatin (XP, n=50) or chemoradiotherapy (XPRT, n=49). Survival analyses were performed in accordance with the AJCC 2010 staging system. Results: According to the AJCC 2010 system, stage migration from IB to II occurred in 71% of the patients; 98% of the T2 N0 cases were reclassified as T3 N0, and 42% of the T1 N1 cases were reclassified as T1 N2. When comparing survival outcomes between the XPRT and XP arms for stage IB cancer (AJCC 2002), no significant difference in 5-year disease-free survival (DFS) between the 2 arms was found. (median 5-year DFS, not reached, P=0.256). The patients classified as having stage IB cancer (AJCC 2002) and reclassified as having stage II cancer (AJCC 2010) exhibited worse prognoses than those who remained in stage IB, although the difference was not statistically significant (5-year DFS rate, 83% vs. 93%). When we compared 5-year DFS in 70 patients with stage II (AJCC 2010), the addition of radiotherapy to XP chemotherapy did not show better outcome than XP alone (P=0.137). Conclusions: The role of adjuvant chemoradiotherapy in the treatment of stage IB GC (AJCC 2002) warrants further investigation.

박유진(Park, YouJin) 학습자중심교과교육학회 2017 학습자중심교과교육연구 Vol.17 No.18

본 연구는 만5세 유아가 그림책의 인물을 어떻게 표현하고, 어떻게 이해하는 지 살펴보는 데에 목적이 있다. 이를 위해 만5세 유아 5명에게 도서대여프로그램의 일환으로, 선정된 도서 중 자신이 원하는 그림책을 골라 자유롭게 그림으로 표현하게 하였다. 유아 5명은 제시된 40권의 그림책 중 37권을 12주 동안 자유롭게 읽었으며, 320개의 그림 표현물 중 인물이 표현된 경우는 262개였다. 유아의 그림 자료는 수집 하였고, 유아-교사 간 면담은 촬영 및 녹음하여 전사하였다. 자료는 해석적 연구방법 절차에 의해 분석하였으며, 담임교사 1인과 유아교육학과 박사과정 3인에게 타당도 검증과정을 거쳤다. 연구결과 유아는 인물을 그림으로 표현할 때 겉모습과 행동을 그림으로써 외면적 요소를 표현하였고, 인물의 색이나 표정을 통해 내면적 요소를 표현하였으며, 인물을 재구성하여 표현하기도 했다. 유아의 그림 표현에서 나타난 유아의 인물 이해는 다음과 같다. 첫째, 줄거리와 인물을 파악한다. 둘째, 시각적인 장치를 파악한다. 셋째, 인물의 감정과 생각을 추론한다. 넷째, 인물과 자기 경험을 연결한다. 다섯째, 이야기에 몰입함으로써 인물에 이입한다. 본 연구는 궁극적으로 유아의 인물이해가 이야기 이해임을 시사한다. 인물을 이해하기 위해서는 이야기의 다양한 요소들을 종합적으로 재조직해야하기 때문이다. The purpose of this study was to examine how five 5-year-old infants express characters in picturebooks and how they understand those. For this, the study arranged five 5-year-old infants to choose their favorite picturebooks from those selected as part of book-lending program and to freely express in a picture. Five 5-year-old infants freely read 37 picturebooks from the provided 40 books for 12 weeks and, of 320 pictorial expressions, those that expressed characters were 262. Infants pictorial data were collected, while interviews between infants and teachers were shot, recorded and transcribed. The data underwent analysis by means of analytic research process and validity was confirmed by one teacher in charge and three persons in doctoral course for pedagogy for infants. As a result of research, the study found that when expressing characters in a picture, infants tended to express exterior elements by drawing outward look and behaviors, to express interior elements and also to express characters by restructuring. The following is what infants understood of characters, seen from their drawing expression. First, infants grasp the outline of the story and characters. Second, they grasp visual installations. Third, they infer feelings and thoughts of the characters. Fourth, they connect the characters with their own experience. Fifth, they empathize with the characters by being immersed in the story. These findings suggest that infant s understanding of characters is eventually that of a story. It s because infants have to reorganize various elements generally in order to understand the character

The purpose of this study was to examine the relationship between intonation familiarity and judgment of statements vs. yes/no questions among 51 native speakers of Korean. Among the participants, 28 from Seoul or Gyeonggi consider themselves as familiar with standard Korean but less familiar with Jeonnam dialects, while 23 from Jeonnam evaluate themselves as familiar with both types of dialects. For data collection, we asked the participants to listen and to judge 30 sentences with –day ending as any of three categories: standard statements, standard yes/no questions, and Jeonnam yes/no questions with a 7-point scale. When a sentence produced was judged as yes/no question, the participant gave the sentence a seven point, while a one point to a statement. According to the data analysis following a linear mixed effects model, the results of this study showed that there was a significant positive relationship between intonation familiarity and sentence-type judgment in regard to the perception of the exceptional and marked mapping of intonation and sentence type. However, there was no relationship between them, considering the perception of the universal and unmarked mapping.

The Influence of Metastatic Lymph Node Ratio on the Treatment Outcomes in the Adjuvant Chemoradiotherapy in Stomach Tumors (ARTIST) Trial: A Phase III Trial

Kim, Youjin,Park, Se Hoon,Kim, Kyoung-Mee,Choi, Min Gew,Lee, Jun Ho,Sohn, Tae Sung,Bae, Jae Moon,Kim, Sung,Lee, Su Jin,Kim, Seung Tae,Lee, Jeeyun,Park, Joon Oh,Park, Young Suk,Lim, Ho Yeong,Kang, Won The Korean Gastric Cancer Association 2016 Journal of gastric cancer Vol.16 No.2

Purpose: In the Adjuvant Chemoradiotherapy in Stomach Tumors (ARTIST) trial, we investigated whether chemoradiotherapy after D2 gastrectomy reduces the rate of recurrence. Recently, the ratio of metastatic lymph nodes to examined lymph nodes (N ratio) has been proposed as an independent prognostic factor in gastric cancer (GC). The aim of this study was to investigate the relationship between the metastatic N ratio and prognosis of GC after curative D2 surgery. Materials and Methods: We retrospectively reviewed the data of 458 ARTIST patients who underwent D2 gastrectomy followed by adjuvant chemotherapy (XP, n=228) or chemoradiotherapy (XPRT, n=230). The disease-free survival (DFS) rates of patients were used to evaluate the influence of N ratio on the treatment outcome. To achieve this, 4 different N ratio categories (0%, 1%~9%, 10%~25%, and >25%) were compared on the basis of their influence on the treatment outcome. Results: On multivariate analysis, the N ratio remained an independent prognostic factor for DFS. The hazard ratios (HRs) for the N ratio categories of 0%, 1%~9%, 10%~25%, and >25% were 1, 1.061, 1.202, and 3.571, respectively. In patients having N ratio >25%, the 5-year DFS rates were 55% and 28% for the XPRT and XP arms, respectively (HR, 0.527; 95% confidence interval, 0.307~0.904; P=0.020). Conclusions: In patients with curatively resected GC, the N ratio was independently associated with DFS. Although this finding warrants further investigation in future prospective studies, the benefit of chemoradiotherapy for D2 resected GC appears to be more beneficial in cancers having N ratios >25%.
