The expression method of advertising photos is the work of systematically and rationally structuring expression elements so that advertising messages can be effectively delivered to consumers. By analyzing case studies and consumer reactions to the expression methods of photos appearing in advertisement images for home appliances, we try to suggest standards for how the characteristics of expression are used in advertisement pictures and how to classify advertisement pictures preferred by consumers. To this end, a classification framework for expression forms shown in advertisement photos was presented, and advertisement images of domestic home appliances were collected and analyzed by product type and release year. The representative advertisement photo expression method derived from the preliminary study was applied to the experimental object to conduct a factor design survey between 2x3 groups. As a result of the preliminary study, it was confirmed that the expression form was changed to emphasize the naturalness of everyday life. As a result of the main study, differences occurred in product attitudes and purchase intentions in the expression form of TV advertisement images, and differences occurred in the types of visual metaphors in advertisement attitudes, product attitudes and purchase intentions. As for the expression form of refrigerator advertisement image, there was a difference in product attitude and purchase intention in the visual metaphor type, and there was a difference in the advertisement effect of the expression form and visual metaphor type according to the properties of home appliances. Through this study, it is expected that it can contribute to the development of advertising photos as practical data for advertising image production by preparing standards for predicting consumer preferred advertising photo expression methods at the stage of advertising production.

The Impact of Customer-Centric Strategy for Brand Creation

Hyunjun Park(박현준) 융복합지식학회 2018 융복합지식학회논문지 Vol.6 No.2

This research investigates how the brand of a company is vital for sustainability and growth. Typically, companies follow the market trend to produce products by analyzing the market only. However, this approach can have short-term profitability. On the other hand, the customer-centric strategy can create a brand where customers are aware and can trust a specific company because of their specific brand entity. Thus, this paper will focus on the customer needs as a priority instead of following the market trend. Moreover, it produces products that can benefit the customer instead of creating a better product to gain market share. Therefore, this research paper explored a cosmetic company called Pinkwonder which have successfully utilized and applied the customer-centric strategy from the beginning and created an organic cosmetic brand where the customers can trust. Currently, the organic cosmetic industry is trendy and attractive industry, especially in South Korea. Thus, there are many different competitors with various organic products to match and follow the current market trend. Therefore, these companies have followed the market trend and have obtained some of the market shares. This paper will explore the differences and importance in brand creation for growth and sustainability between the market trend follower versus customer centric-strategy. Also, it will attempt to discover that the customer-centric strategy may be more viable and sustainable in the long-term.

A Comparative Study of the Korean Adjunct Mwel ‘What’ and Its Chinese Counterpart

Hyunjun Park,Myung-Kwan Park 언어과학회 2021 언어과학연구 Vol.- No.98

Many languages use the wh-word to produce negative speaker attitude in the negative wh- construction. In this case, the constructions do not get an interrogative reading. The Korean mwel can be used not only as an argument but also as an adjunct. When mwel is used as an adjunct, the construction mainly expresses the speaker’s negative attitude. In this paper, we investigate how the Korean adjunct mwel expresses emphatic negative force, compared with its Chinese counterpart shenme ‘what’ (Cheung 2008; Dong and Jin 2019; Lau and Tsai 2020; Pan 2014; Yang 2008; among others). Following Rizzi (1997, 1999, 2004), we have argued that the adjuncts mwel and shenme should move to ForceP of the left periphery of CP in order to appropriately derive the speaker’s negative force.

Objective: Patients with traumatic acute subdural hematoma (ASDH) often require surgical treatment. Among patients who primarily underwent craniotomy for the removal of hematoma, some consequently developed aggressive intracranialhypertension and brain edema, and required secondary decompressive craniectomy (DC). To avoid reoperation, we investigated factors which predict the requirement of DC by comparing groups of ASDH patients who did and did not requireDC after craniotomy. Methods: The 129 patients with ASDH who underwent craniotomy from September 2007 to September 2017 were reviewed. Among these patients, 19 patients who needed additional DC (group A) and 105 patients who underwent primarycraniotomy only without reoperation (group B) were evaluated. A total of 17 preoperative and intraoperative factors wereanalyzed and compared statistically. Univariate and multivariate analyses were used to compare these factors. Results: Five factors showed signifcant differences between the two groups. They were the length of midline shifting tomaximal subdural hematoma thickness ratio (magnetization transfer [MT] ratio) greater than 1 (p<0.001), coexistence of intraventricular hemorrhage (IVH) (p<0.001), traumatic intracerebral hemorrhage (TICH) (p=0.001), intraoperative fndingsshowing intracranial hypertension combined with brain edema (p<0.001), and bleeding tendency (p=0.02). An average valueof 2.74±1.52 was obtained for these factors for group A, which was signifcantly different from that for group B (p<0.001). Conclusion: An MT ratio >1, IVH, and TICH on preoperative brain computed tomography images, intraoperative signsof intracranial hypertension, brain edema, and bleeding tendency were identifed as factors indicating that DC would berequired. The necessity for preemptive DC must be carefully considered in patients with such risk factors Objective: Patients with traumatic acute subdural hematoma (ASDH) often require surgical treatment.

Exploring Knowledge Distribution in Neural Network Parameter

Hyunjun Jang,Minuk Ma,Chang D. Yoo 대한전자공학회 2019 대한전자공학회 학술대회 Vol.2019 No.6

Recently, convolutional neural networks have revealed remarkable classification performance on the ImageNet benchmark. Deep learning methods have successfully been applied to many fields including detection, reinforcement learning, natural language processing, etc. However, there is no clear understanding as to why deep learning methods perform well. In this paper, we investigate the knowledge distribution in neural network parameters specifically for policy networks. With both top-down and bottom-up investigation methods, we argue that the neurons in policy networks divide the labors in a modular way. We find that when there are too many neurons considering the complexity of the task, some neurons do not work at all, and can actually be removed for computational efficiency. Experiments on gym CartPole environment demonstrate our hypotheses.

Hyunjun Kim(김현준),Minho Kim(김민호) 한국컴퓨터그래픽스학회 2015 컴퓨터그래픽스학회논문지 Vol.21 No.2

본 논문에서는 방향성이 있는 포인트 클라우드로부터 3차원 개체의 표면을 복구하는 향상된 기법을 제안한다. 본 방법은 기존에 널리 사용되고 있는 최소 자승법에 기초하고 있지만, 7-방향 박스-스플라인과 체심입방(BCC: Body-Centered)격자를 활용하여 카티시안 격자와 B-스플라인에 기반한 기존의 방법들에 비해 좀 더 나은 품질의 곡면을 빠른 시간에 얻을 수 있다. 구체적으로는,기존의 두 방법론과 비교해 보았을 때 본 방법은 평균적으로 약 53%의 연산시간만에 좀 더 나은 품질의 곡면을 얻을 수 있다. In this paper, we propose an improved surface reconstruction method from an oriented point cloud. Our method is a classical least-square scheme, but is based on the 7-direction box-spline and the BCC (Body-Centered Cubic) lattice, which results in surfaces with superior quality and lower computational overhead, compared to other methods based on the B-splines on the Cartesian lattice. Specifically, when compared with two of the most popular techniques our method results in better surfaces but only takes ? 53% computation time.

Hyunjun Choe,이수미,황효진,주정찬,조대행,김용환 한국생물공학회 2014 Biotechnology and Bioprocess Engineering Vol.19 No.4

The efficient regeneration of nicotinamidecofactors is an important process for industrial applicationsbecause of their high cost and stoichiometric requirements. In this study, the FDH1 β-subunit of NAD-dependentformate dehydrogenase from Methylobacterium extorquensAM1 was heterologously expressed in Escherichia coli. Itshowed water-forming NADH oxidase (NOX-2) activity inthe absence of its α-subunit. The β-subunit oxidized NADHand generated NAD+. The enzyme showed a low NADHoxidation activity (0.28 U/mg enzyme). To accelerate electrontransfer from the enzyme to oxygen, four electron mediatorswere tested; flavin mononucleotide, flavin adenine dinucleotide,benzyl viologen (BV), and methyl viologen. Alltested electron mediators increased enzyme activity; additionof 250 μM BV resulted in the largest increase in enzymeactivity (9.98 U/mg enzyme; a 35.6-fold increase comparedwith that in the absence of an electron mediator). Withoutthe aid of an electron mediator, the enzyme had a substratebindingaffinity for NADH (Km) of 5.87 μM, a turnoverrate (kcat) of 0.24/sec, and a catalytic efficiency (kcat/Km) of41.31/mM/sec. The addition of 50 μM BV resulted in a22.75-fold higher turnover rate (kcat, 5.46/sec) and a 2.64-fold higher catalytic efficiency (kcat/Km, 107.75/mM/sec).

Differences among Credit Rating Agencies and the Information Environment

Hyunjun PARK,Youngtae YOO 한국유통과학회 2019 The Journal of Asian Finance, Economics and Busine Vol.6 No.2

In the Korean capital market, there are three credit rating agencies. Potential credit ratings based on credibility in the financial market are calculated independently for each rating agency. It often happens that despite the fact that the grades of the rating agencies are the same and have the same rating system, their actual ratings are different, even for the same firm. In such circumstances, investors may wonder why. In this study, we assume that the cause is the information environment in which the company operates. The credit ratings of rating agencies are mainly classified into bonds or commercial papers. The bonds are rated primarily for long-term of three years or more, and commercial papers specify ratings for less than one year. The information environment to be verified in this study was observed with a commercial paper. Under the assumption the larger the analyst following is, the more transparent is the information environment, we analyzed the influence of the number of analysts following on the degree to which ratings conflicted among credit rating agencies. The results of our analysis confirmed that opinion conflict among credit rating agencies is clearly reduced for companies with good information environments.

Hyunjun Cho 언어과학회 2021 언어과학연구 Vol.- No.97

This study examines the effects and perceptions regarding Quizlet-based middle school English performance assessment. To implement performance assessment as a variable, the researcher conducted a study divided into two phases. In the first stage, the researcher studied the effect of using Quizlet according to their autonomy on 52 middle school students. In the second stage, the same students were examined about the effects and perceptions of Quizlet-based performance assessment. This study conducted pre-and post-tests to identify the effectiveness of the Quizlet-based performance assessments. The results showed that the overall vocabulary test scores of the participants improved and that the students showed a greater degree of improvement in the second stage than in the first stage. A Likert-scale survey with open-ended questions was also used to investigate students’ perceptions of the Quizlet-based performance assessment. Students perceived the Quizlet-based performance assessment positively. These results provided pedagogical implications for Quizlet-based performance assessment.
