Han,Sang-Lin,Baek,Mi-Young 한국상품학회 2010 商品學硏究 Vol.28 No.6

The main purpose of this study is to test empirically that used theories of retailer equity and tool of retailer equity about the two of major distribution channels - discount store and on-line shopping. We used indices from Arnett, Laverie and Meiers (2003) and those factors are retailer loyalty, name awareness, service quality, retailer associations, and perceived value. For this study, we collected data from major discount stores and on-line shopping sites in South Korea. As a result, only retailer loyalty influences on retailer equity in discount store and retailer loyalty and product quality influence retailer equity. Our paper is organized as follows. First, we discussed about retailer equity and the underlying dimensions of retailer equity. Second, based on the research of Arnett, Laverie and Meiers (2003), we demonstrate a indexes of retailer equity using regression analysis for comparing discount store and on-line shopping. Third, we discuss some managerial implications of this research for retail practitioners and suggest for future research.

Purpose : To evaluate the utility of mammography and ultrasonography in study of morphologic differential diagnosis between malignant and benign mass. Materials and Methods : Average age of patients with breast cancer was 48.4 year-old, and that of fibroadenoma was 29.4 year-old. The equipments used for examination were MF-159 high frequency mammography(Bennet Co.) and Acoustic image 5200S. We evaluated mammographic findings about breast parenchymal pattern, calcification, margin and size of the mass associated tumor nature, and ultrasonographic findings about shape, height and width, internal homogenicity and echo pattern, wall contour, boundary echo, and posterior shadow in breast mass. Thirty-seven of mammographic findings and 34 cases of ultrasonogreaphic findings in pathologically proven breast cancer and 34 case of mammographic findings and 71 cases of ultrasonographic findings in breast fibroadenoma were reviewed retrospectively. Results : In mammographic study, the parenchymal patterns of breast cancer according to Wolfe classification were NI(16.2%), PI(24.3%), P@(37.8%), and DY(21.6%) and those in fibroadenoma were NI(3.1%), Pl(11.7%), P2(35.2%),and DY(50%). Mammographic findings about presence of calcification were as follows; only calcification(16.2%), only mass(51.3%), and mass with calcification(32.5%) in breast cancer, and only mass(91.2%), mass with calcification(8.8%) in fibroadenoma. The features of mass margins were classified as ill-defined margin(45.9%), well-defined(5.4%), and well-defined with partial spiculation(48.6%) in breast cancer and ill-defined(20.5%), well-defined(73.5%), and well-defined with partial spiculation(5.8%) in fibroadenoma. The mass were grouped by size; 1-2cm(37.8%), 2-4cm(45.9%), and 4-6cm(16.3%) in breast cancer and 1-2cm(79.4%), 2-4cm(17.6%), and 4-6cm (3.0%) in fibroadenoma. On ultrasonographic study, the shape of masses in breast cancer were lobulated(82.3%),oval(14.7%), and round(3.0%),and those in fibroadenoma were lobulated(14.0%), oval(57.7%), and round(18.3%). The cases that the height was longer than width were 32.3% in breast cancer and 0% in fibroadenoma. The findings about homogenecity and echo patterns were as follows; hypoechoic(52.9%) and mixed(47.1%) in breast cancer and hypoechoic(2.8%), hypoechoic(63.4%), and mixed(33.8%) in fibroadenoma. The margin of masses were smooth in 85.9% of fibroadenoma, and irregular in 73.6% of breast cancer. The boundary echoes of masses and decreased posterior echo shadow were seen only in 61.8% and 55.9% of breast cancer, respectively. Conclusion: The margin and calcifications are more clearly delineated on mammography but breast cancer and fibroadenoma, both are more commonly developed in dense parenchymal pattern(P2+DY),and there findings are easily obscured in mammography. So ultrasoography is very useful in these masses evaluation, especially amoung young patients.

Renal artery stenosis is the one of causes of hypertension in a small percentage of all patients but is only anatomical cause that can be treated by means of surgery and percutanecous transluminal angioplasty. Angiography is the golden standard for diagnosis of renal artery stenosis, but a little invasive. With the advent of abdominal Doppler ultrasonography, renal artery stenosis could be diagnoed noninvasively. The experienced hands appears to be valuable in the doppler examination, ut some investigators consider it almost useless. The authors studied the effect of stenosis of renal artery on the downstream intrarenal blood flow, a snare was placed around renal artery in 12 rabbits and compressed to create stenosis while Doppler ultraonographic curve and flow index were obtained from main renal and interlobar arteries by means of placement of 10-MHz curved linear tranducer directly on the surface of kidney. The Doppler measurements were compared with the percentage of stenosis on angiograms. The results were as follow: 1. Ten satisfactory angiograms and Doppler ultrasonograms were obtained. 2. Three renal arteries were created stenosis below 70% (Group A), Seven were above 70% (Group B). 3. The ranges of RI (resistance index) were 0.61-0.86 (mean 0.78±0.154) at main renal arteries, 0.57-0.85 (mean 0.77±0.231) at interlobar artery. The range of PS (peak systolic velocity) were 13.1-28.8 (mean 21.65±4.445) m/sex at main renal artery, 5.2-18.1 (mean 11.74±4.095) m/sec at interlobar arteries. The RI of rabbits were higher than those of human (mean 0.58±0.05). 4. The range of RI in stenotic arteries of group B were 0.45-0.74 (mean 0.57±0.143) at main renal artery, 0.52-0.65 (mean 59±0.051) at interlobar arteries. The range of PS were 11.2-21.3 (mean 15.04±3.755) m/sec at main renal arte교, 5.7-11.3 (mean 8.24±2.056) at interlobar artery. The difference were statistical y significant (P=0.0302), but without remarkable change in group A. 5. Doppler ultrasonographic curve during progressive compression of renal artery showed dampened systolic waveform and diagonal upstroke at main renal arteries (71.4%) and interlobar arteries (85.7%) in group B, but without remarkable change in group A. 6. Release of the arterial compression caused higher than normal peak systolic velocity initially, at main renal arteries (42.9%) and interlobar arteries (28.6%). but the curve of all rabbits returned to normal within 5 minutes. The Doppler ultrasonographic index and curve were not changed on follow up Doppler ultrasonogram at 5 min. 10 min. 30 min. and 1 hour. The change of the systolic curves that compressed experimentally is identical to change in the pulsus tardus and parvus waveforms seen in both acute and chronic severe renal artery stenosis in humans, can helpul for the diagnosis of renal artery stenosis and the effects of treatment by percutaneous tranluminal angioplasty and surgery.

Surface wettability and contact angle analysis by dissipative particle dynamics

Lin, Tzung-Han,Shih, Wen-Pin,Chen, Chuin-Shan Techno-Press 2012 Interaction and multiscale mechanics Vol.5 No.4

A dissipative particle dynamics (DPD) simulation was presented to analyze surface wettability and contact angles of a droplet on a solid platform. The many-body DPD, capable of modeling vapor-liquid coexistence, was used to resolve the vapor-liquid interface of a droplet. We found a constant density inside a droplet with a transition along the droplet boundary where the density decreased rapidly. The contact angle of a droplet was extracted from the isosurfaces of the density generated by the marching cube and a spline interpolation of 2D cutting planes of the isosurfaces. A wide range of contact angles from $55^{\circ}$ to $165^{\circ}$ predicted by the normalized parameter ($|A_{SL}|/B_{SL}$) were reported. Droplet with the parameters $|A_{SL}|>5.84B{_{SL}}^{0.297}$ was found to be hydrophilic. If $|A_{SL}|$ was much smaller than $5.84B{_{SL}}^{0.297}$, the droplet was found to be superhydrophobic.

Objective: To conduct a meta-analysis to investigate the value of EBV DNA in diagnosis of nasopharyngeal cancer (NPC) in Asian populations, and provide important evidence for screening. Methods: Prospective or respective case-control or cohort studies regarding the detection role of EBV DNA for NPC were included in our study. We conducted a comprehensive literature search in PubMed, EMBASE, and the Chinese Biomedical Database (CBM database between January 1980 and March 2012. Results: A total of 18 studies with 1492 NPC cases and 2641 health controls were included. Almost of the included studies were conducted in China, and only one other conducted in Thailand. The overall results demonstrated that the pooled sensitivity, specificity, positive likelihood (+LR) and negative likelihood (-LR) were 0.73 (0.71-0.75), 0.89 (0.88-0.90), 8.84 (5.65-13.84) and 0.19(0.11-0.32), respectively. The overall EBV DNA detection showed the largest area of 0.932 under the summary receiver operator curve (SROC). The accuracy of detection by plasma for NPC (0.86) was higher than in serum (0.81), with largest areas under the SROC of 0.97 and 0.91, respectively. Conclusion: Our results demonstrated the EBV DNA detection in plasma or serum has high sensitivity and specificity in diagnosis of NPC, especially in Chinese populations with a high risk of cancer.

As seen in the recent business market situation, an increasing number of industrial manufacturers and suppliers are moving from adversarial to cooperative exchange attitudes that support the long-term relationships with their customers. This article presents the results of an empirical study of the antecedent factors of business relationships in metal industry of the United States.<BR>  Commitment has been reviewed as a significant and critical variable in research on inter-organizational relationships (Hong et al. 2007, Kim et al. 2007). The future stability of any buyer-seller relationship depends upon the commitment made by the interactants to their relationship. Commitment, according to Dwyer et al. [1987], refers to "an implicit or explicit pledge of relational continuity between exchange partners" and they consider commitment to be the most advanced phase of buyer-seller exchange relationship.<BR>  Bonds are made because the members need their partners in order to do something and this integration on a task basis can be either symbiotic or cooperative (Svensson 2008). To the extent that members seek the same or mutually supporting ends, there will be strong bonds among them. In other words, the principle that affects the strength of bonds is "economy of decision making" [Turner 1970]. These bonds provide an important idea to study the causes of business long-term relationships in a sense that organizations can be mutually bonded by a common interest in the economic matters. Recently, the framework of structural bonding has been used to study the buyer-seller relationships in industrial marketing [Han and Sung 2008, Williams et al. 1998, Wilson 1995] in that this structural bonding is a crucial part of the theoretical justification for distinguishing discrete transactions from ongoing long-term relationships.<BR>  The major antecedent factors of buyer commitment such as technology, CLalt, transaction-specific assets, and importance were identified and explored from the perspective of structural bonding. Research hypotheses were developed and tested by using survey data from the middle managers in the metal industry.<BR>  H1: Level of technology of the relationship partner is positively related to the level of structural bonding between the buyer and the seller.<BR>  H2: Comparison level of alternatives is negatively related to the level of structural bonding between the buyer and the seller.<BR>  H3: Amount of the transaction-specific assets is positively related to the level of structural bonding between the buyer and the seller.<BR>  H4: Importance of the relationship partner is positively related to the level of structural bonding between the buyer and the seller.<BR>  H5: Level of structural bonding is positively related to the level of commitment to the relationship.<BR>  To examine the major antecedent factors of industrial buyer"s structural bonding and long-term relationship, questionnaire was prepared, mailed out to the sample of 400 purchasing managers of the US metal industry (SIC codes 33 and 34). After a follow-up request, 139 informants returnedthe questionnaires, resulting in a response rate of 35 percent. 134 responses were used in the final analysis after dropping 5 incomplete questionnaires. All measures were analyzed for reliability and validity following the guidelines offered by Churchill [1979] and Anderson and Gerbing [1988]., the results of fitting the model to the data indicated that the hypothesized model provides a good fit to the data.

Why Consumers Use Mobile Commerce? - International Comparative Study of M-Commerce Model

Han, Sang-Lin,Nguyen, T.P. Thao,Nguyen, V. Anh Korean Marketing Association 2016 ASIA MARKETING JOURNAL Vol.18 No.3

Development of information and communication technology is changing commerce environment and consumer purchasing behavior has also been changed. Globalization is becoming increasingly prevalent in the world today and many factors such as culture, politics, and economics may influence the applicability of management theories. Concurrently, corporate managers are faced with the challenge of offering usable and useful applications to the local users. Besides, many scholars strongly support that the criteria for M-Commerce adoption in developing countries are different from that of developed countries, due to cultural, security, social, political, economic, and technological aspects. This research tried to investigate the differences on the adoption of mobile commerce between developed and developing countries. In this study, the motivation for studying advanced mobile phone services adoption in the South Korea and Viet Nam is presented. Second, M-Commerce adoption model is introduced as a starting point for the research model. We then integrate price, personal innovativeness, quality dimension and perceived of playfulness into our model. Next, we describe our method and report the results of our analysis. The paper concludes with a discussion of the results from both the South Korea and Viet Nam with implications.

“獨體”,“合體” 源流及其應用

( Lin Han ) 한국한자한문교육학회 2014 漢字 漢文敎育 Vol.34 No.-

“독체자”와 “합체자”는 한자 교육에서 항상 만나게 되는 상대적 개념이다. 그런 데 여기서 “체”란 무엇인가? 이전에 이에 대한 본격적인 논의가 없었다. 본문은 이 논의를 아래의 세 방향에서 진행하였다. 우선 “독체자”와 “합체자”의 원류에 대해 살펴봄으로써 “체”의 의미를 밝히려 하였다. 허신의 “문”과 “자”는 문자의 역사적 발전 단계에서 나온 것으로, ‘문’은 상형 단계의 전체 모양을 설명하는 형식의 구조를 가지고 있는 문자를 지칭하며, ‘자’는 글자의 구성 요소를 조합하여 글자를 만들어 내는 부호 문자 단계의 문자를 말한다. 그와 관련된 “독체”와 “합체”는 글자를 만들어 내는 것과 글자를 구성하는 두 가지 방면의 내용을 포함하고 있다. 두 번째는 학계에서는 이에 대해 각기 다른 분석의 각도로부터 시작한 다양한 논의가 있었는데 이에 대해 논증하였다. 그 다음으로 “독체”와 “합체”와 관련된 한자자형구조 분석법을 서술하였다. 이 분석은 두 가지 방법으로 진행하였는데, 첫째는 구조 기능 분석을 통해 글자를 구성하는 구건이 어떤 기능으로 글자의 구성에 참여하였는가를 밝히는 것이었다. 두 번째는 자소 분석법으로 자형의 조합 요소에 집중해 보면 어떤 경우는 구 건의 기능성과는 일정한 관계가 없다. 다음으로 현대한자학과 중국어 국제 교육 영역에서 구체적으로 “독체”와 “합 체”를 사용하는 양상을 분석하고 이를 서술하였다. 현대한자학에서는 구조 기능 분석과 자소 분석이 결합된 양상으로 나타나며, 중국어 국제 교육의 영역에서는 자소 분석을 따르고 있었다. 결론적으로 “독체”는 한자의 기능 생성성에만 집중되 어지고, “합체”는 구조의 분석에만 집중되어짐을 알 수 있었다. 이런 특징을 잘 살려 고금 한자의 형태를 분석하고 이용하는 것은 효과적인 교육 방법이 될 수 있다. Through observing WEN and ZI that elucidated in SHUOWENJIEZI, this thesis definates TI as construction unit in Character structure. It relates two Chinese Character systems,one hieroglyphic system,the other one symbol system. On the base of TI, there are two kinds of analysis methods that have an important role in modern Character study and teaching, one standing at the point of Character constructure and function, the other being concerned with Character constituted units. Analogic laws is beneficial to teaching penetrating ancient and modern Chinese Character.

Tests and mechanics model for concrete-filled SHS stub columns, columns and beam-columns

Lin-Hai Han,Xiao-Ling Zhao,Zhong Tao 국제구조공학회 2001 Steel and Composite Structures, An International J Vol.1 No.1

A series of tests on concrete-filled SHS (Square Hollow Section) stub columns (twenty), columns (eight) and beam-columns (twenty one) were carried out. The main parameters varied in the tests are (1) Confinement factor (x ) from 1.08 to 5.64, (2) concrete compression strength from 10.7MPa to 36.6MPa, (3) tube width to thickness ratio from 20.5 to 36.5. (4) load eccentricity (e) from 15 mm to 80 mm and (5) column slenderness (l) from 45 to 75. A mechanics model is developed in this paper for concrete-filled SHS stub columns, columns and beam-columns. A unified theory is described where a confinement factor (x ) is introduced to describe the composite action between the steel tube and filled concrete. The predicted load versus axial strain relationship is in good agreement with stub column test results. Simplified models are derived for section capacities and modulus in different stages of the composite sections. The predicted beam-column strength is compared with that of 331 beam-column tests with a wide range of parameters. A good agreement is obtained. The predicted load versus midspan deflection relationship for beam-columns is in good agreement with test results. A simplified model is developed for calculating the member capacity of concrete-filled SHS columns. Comparisons are made with predicted columns strengths using the existing codes such as LRFD (AISC 1994), AIJ (1997), and EC4 (1996). Simplified interaction curves are derived for concrete-filled beam-columns.
