As digital transformation accelerates, the proportion of non-face-to-face services in financial services is also increasing. Recently, user experience has emerged to secure competitiveness in mobile services, and analysis techniques to improve user experience have emerged. User review data, one of the data used for quantitative evaluation, contains a lot of unnecessary information, which is time-consuming to derive improvement directions. Therefore, this study aims to develop a UX analysis system based on the hierarchy of UX needs by using a cosine similarity algorithm and analyze user review data of Kookmin Bank, Woori Bank, Kakao Bank, and Toss for verification. This study proved that the developed UX analysis system is a system that can effectively analyze UX through the analysis of user review data. The system of this study is expected to be easily used to identify improvement plans for the hierarchy of UX needs in an agile organization that needs to quickly reflect customer feedback.
The study surveyed care giver's perceptions of baby food and evaluated the quantitative and qualitative aspects of Korean websites related to the baby food for atopic dermatitis infants. Sources of care giver information about baby food were the internet (93%), clinics (57%), television (52%), oriental clinics (37%), and neighbors (6%). The five most commonly-used internet search engines (Daum, Google, Nate, Naver and Yahoo) were searched using the terms "atopic dermatitis", "weaning food" and "baby food". The searched websites included oriental medical clinics (38.8%), online merchant companies (13.4%), corporations (13.4%), medical clinics (11.9%), related associations (11.9%), public health centers (4.4%) and personal sites (4.4%). Website food and nutrition information included medical information about baby food for atopic dermatitis (92.6%), baby food for atopic dermatitis (67.6%), related community (58.8%), product information (32.4%) and baby food preparation for atopic dermatitis (23.5%). Qualitative evaluation was conducted based on the American Library Association website checklist; Website operator and information sources were provided for 62.7% and 38.8% of the websites, respectively. The purpose of a website was more explicitly stated in medical clinic sites than nonmedical sites. Only 24.2% of websites had a title that appropriately reflected the site's purpose. The majority (92.5%) of the sites were easy to read and understand. Information was judged to be sufficient in 65% of the medical sites and 74.1% of non-medical sites. A feedback menu and search function were enabled in 85.1% and 28.4% of the sites, respectively. The mean score for quality grade was 14.64 (range 9-19). In conclusion, in order to improve the information of baby food for atopic dermatitis infants in websites, accurate information by experts and continuing monitoring are highly required.

We present H I gas kinematics and star formation activities of NGC 6822, a dwarf galaxy located in the Local Volume at a distance of ~490 kpc. We perform profile decomposition of the line-of-sight velocity profiles of the high-resolution (~42.4" × 12") spatial; ~1.6 km/s spectral) H I data cube taken with the Australia Telescope Compact Array (ATCA). For this, we use a new tool, the so-called BAYGAUD (BAYesian GAUssian Decompositor) which is based on Bayesian Markov Chain Monte Carlo (MCMC) techniques, allowing us to decompose a line-of-sight velocity profile into an optimal number of Gaussian components in a quantitative manner. We classify the decomposed H I gas components of NGC 6822 into kinematically cold, warm or hot ones with respect to their velocity dispersion: 1) cold: < 4 km/s, 2) warm: 4 ~ 8 km/s, 3) hot: > 8 km/s. We then derive the Toomre-Q parameters of NGC 6822 using the kinematically decomposed H I gas maps. We also correlate their gas surface densities with the surface star formation rates derived using both GALEX far-ultraviolet and WISE 22 micron data to examine the impact of gas turbulence caused by stellar feedback on the Kennicutt-Schmidt (K-S) law. The kinematically cold component is likely to better follow the linear extension of the Kennicutt-Schmidt (K-S) law for molecular hydrogen (H2) at the low gas surface density regime where H I is not saturated.

Objective: The introduction of government support programs for small businesses in 1993 aimed to enhance awareness and capabilities in industrial health management among small business proprietors, marking a continuous expansion over the past three decades. Despite this growth, there has been a conspicuous absence of comprehensive evaluations regarding the efficacy of these initiatives. In response, this study endeavors to conduct a thorough policy evaluation. Method: Through a meticulous approach, we conducted an analysis of in-depth interviews with eight individuals possessing expertise in the administration of government support programs for small businesses. These interviews were sourced from personnel affiliated with government ministries and public agencies. Results: In the analysis, it was found that small-scale business government support programs operate primarily based on quantity rather than receiving support from business owners regarding their necessity or utility. Consequently, these programs have failed to yield substantial effects on altering the perception of business owners or improving the working environment within the businesses. Conclusion: This study assumes significance in its capacity to discern intricate procedural challenges in program implementation, which often elude quantitative scrutiny. Furthermore, it provides pivotal insights for enhancing government support programs.

This paper intends to develop an assesment technique for the rapid and quantitative evaluation of tunnel safety during tunnel excavation by using displacement measurements. Control criteria for the field measurements are provided at tunnel construction sites in Korea and other countries. However, it was known that the criteria were not clear and varied depending on the construction sites. In order to make a reasonable support for guidelines, critical strain concept is introduced in this study. And the engineering meanings of the critical strain concept are investigated precisely. In order to do this, at first, the engineering meanings of the original concept from the previous researchers was investigated theoretically for the evaluation of tunnel safely. Subsequently displacement data were obtained by using the commercial program, then the evaluation of tunnel safely was conducted with the view point of previous researches. Additionally, strains are determined from the feedback analyses program by inputting measured displacements that were obtained from the commercial program, then the evaluation of tunnel safety was discussed with the critical strain concept. Consequently it can be concluded that the evaluation of tunnel safety can be determined quantitatively and rapidly in the field by introducing the critical strain concept.
In this paper we designed the motor control IP Core and evaluate its quality from the viewpoint of IP reuse. The most attractive merit of this methodology, so called IP-based hardware design, is hardware reuse. Although various vendors designed hardware with the same specification and got the same functional results, all that IPs is not the same quality in the reuse aspect. As tremendous calls for SoC have been increased, associated research about IP quality standard, VSIA(Virtual Socket Interface Alliance) and STARC(Semiconductor Technology Academic Research Center), has been doing best to make the IP quality evaluation system. And they made what conforms to objective IP design standard. We suggest the methodology to evaluate our own designed motor control IP quality with this standard. To attain our goal, we designed motor control IP that could control the motor velocity and position with feedback compensation algorithm. This controller has some IP blocks : digital filter, quadrature decoder, position counter, motion compensator, and PWM generator. Each block's functionality was verified by simulator ModelSim and then its quality was evaluated. To evaluate the core, We use Vnavigator for lint test and ModelSim for coverage check. During lint process, We adapted the OpenMORE's rule based on RMM (Reuse Methodology Manual) and it could tell us our IP's quality in a manner of the scored value form. If it is high, its quality is also high, and vice versa. During coverage check ModelSim-SE is used for verifying how our test circuits cover designs. This objective methods using well-defined commercial coverage metrics could perform a quantitative analysis of simulation completeness. In this manner, We evaluated the designed motor control IP's quality from the viewpoint of reuse. This methodology will save the time and cost in designing SoC that should integrate various IPs. In addition to this, It can be the guide for comparing the equally specified IP's quality. After all, we are continuously looking forward to enhancing our motor control IP in the aspect of not only functional perfection but also IP reuse to prepare for the SoC-Compliant motor control IP design.

The primary responsibility for the oral hygiene of the disabled is usually the parents. Dental care of the disabled is early detection and recovery of lesions and continuous management. For this to be successful it is necessary to use diagnostic tool that can detect the early stages of dental caries which is difficult to detect with the naked eye. It is also important to educate and motivate the caregivers on oral hygiene management. Quantitative Light-induced Fluorescence-Digital (Billuminator, Inspektor Researh Systems BV, Amsterdam, The Netherlands), which provides overall caries inspection and visual information, can be useful for caregiver education. A 3-year-old girl who was hospitalized with Pallister-Killian syndrome, Hypothyroidism visited our clinic with chief complaint of rugged upper incisors. This girl had multiple dental caries and oral hygiene was very poor. Periodic QLF-D images were taken to provide caregiver education and oral hygiene management was improved. A 13-year-old girl with cerebral palsy visited our clinic for regular check up. Using QLF-D, we explained to the parents that there is a need for treatment of dental caries, and education of oral hygiene management was conducted. Improvement of oral hygiene in the disabled can be achieved through caregiver education. QLF-D is a diagnostic device that can detects early caries by irradiating light in the visible ray area to the teeth. It can also detects microleakage of restoration, plaque and calculus without disclosing agent. Clinicians can use the QLF-D to perform a general oral examination for the disabled. Also, QLF-D can be used to store visual information and educate caregivers. The accumulation of information using QLF-D makes it possible to provide feedback on oral care of parents, which is more advantageous for caregivers education.

Although the pulse diagnosis is the one of the most important diagnostic process to traditional medical doctors, there is no proper communication tool between experts and trainees. In this paper, we have developed a indentation training system which consists of a hardware measuring indent pressure on artificial arm quantitatively and a software providing a indentation training program. The hardware for measurement of indent pressure profile includes 3 load cells embedded in the artificial arm, signal amplification part and digitization part, NI-USB 6009 with 200Hz sampling rate. For setting up a relationship table between weights and output voltages, 8 standard weights were used. To evaluate this hardware, 3 oriental medical specialists were involved and their indent pressure profile were recorded three times respectively. From these, it was found that pulse diagnosis process could be divided into 3 periods and the maximum load were $500g{\cdot}f$ approximately while doctors perform a pulse diagnosis. The indentation training program was implemented with LabView and designed to monitor the differences between the pressure profile of a expert and that of a trainee so to offer some visual feedback to the trainee. Also, this program could provide the trends of training performances. With this developed system, the education of pulse diagnosis is expected to be more quantitative and effective.
Purpose: This study was conducted to develop, validate, and assess the reliability of a questionnaire for nutritional literacy among young Korean adults. Methods: The draft questionnaire contained 65 items in 7 domains (i.e., dietary guideline, nutrition and health, nutrients, 5 food groups [food bicycle], nutrition labeling, portion size, and nutrition management for disease prevention). The authors developed a draft questionnaire based on a literature review. After multiple drafts, 52 items were retained and 13 were eliminated in the 7 domains according to professional advice from 5 nutrition experts. A panel of experts (n = 20) comprised of clinical dietitians and nutrition professors completed the content validity assessment, including quantitative and qualitative feedback. As the results, all items of the portion size were eliminated from the questionnaire. A sample of 211 young adults completed the test-retest reliability assessment. Test-retest reliability was evaluated using intra-class correlation coefficient (ICC) and inter-item reliability by Cronbach α coefficient. Results: The final questionnaire contained 30 items with 5 questions each on the dietary guideline, nutrition and health, nutrients, 5 food groups (food bicycle), nutrition labeling, and nutrition management for disease prevention. The Lawshe content validity ratio for domains ranged from 0.60 to 1.00. The ICC scores for questions ranged from 0.64 to 0.86. Cronbach's α for domains ranged from 0.83 to 0.90 and for the overall questionnaire was 0.87. Conclusion: The questionnaire showed strong content validity, test-retest reliability, and high inter-item reliability, indicating that it is a useful tool for assessing nutritional literacy of young adults.
The dual system in Korea already plays an important role in quantitative terms in the Korean lifelong vocational competency development system. However, since most of the existing dual system performance management plans in Korea focus on qualification-linked dual system, research on the effective performance management of the four-year university-driven dual system is very insufficient. This paper presents multiple measures for developing a performance management system suitable for the university-driven dual system to achieve qualitative improvement of the contract departments of the dual colleges or universities. As an approach to the end, a performance evaluation system is established by developing the evaluation items and indicators for the dual colloeges' contract departments. Next, it analyzes the needs of various stakeholder groups such as field teachers of the involved companies, students in apprenticeship and OJT professors of KOREATECH through FGI's and polls to diagnose the current operational performance, especially the causes of high drpout rates of the contract departments. From these results, the paper presents firstly the development of measuring methods for the developed performance indicators of the evaluation system and then a systemic performance management system which is based on 'input-transformation-outcome-feedback' structure. In addition, some measures for improving the high dropout rate and performance are presented from the viewpoints of each stakeholder.
