Purpose: This study conducted an Importance-Performance Analysis (IPA) of selective attributes of Home Meal Replacement (HMR) as well as it examined the consumers' needs and willingness to buy HMR products to explore the need for developing more HMR products. Methods: This study was conducted among domestic consumers living in Seoul and its metropolitan areas, in the age range from the 20s to the 50s, and who had experience in purchasing HMR products. From the 490 surveys retrieved, 472 (96.3%) valid surveys were analyzed. Results: The analysis of the frequency of consuming HMR products showed the following results: 247 respondents answered '1-3 times a month' (52.3%); 167 respondents stated '1-2 times a week' (35.3%). With respect to the reason of purchase, 'simplicity of the recipe' was the most common, accounting for 188 respondents (39.8%), followed by 'time efficiency' accounting for 172 respondents (36.4%). Analysis of the demand for bibimbap (mixed rice) HMR products showed that 'chicken bibimbap' had the highest preference with 5.32 points, followed by 'bulgogi bibimbap' (5.08 points), and 'kimchi bibimbap' (4.96 points). In the case of HMR products that need to undergo further development, 'low-sodium products' received the highest points of 5.41 points, followed by 'small packaged products' (5.05 points), and 'functional products' (4.98 points). The factor analysis of the 13 selective attributes showed that they can be divided into 3 factors. The IPA analysis of the selective attributes of HMRs showed 'hygiene', 'taste', 'easy to go packaging', 'convenience in intake', and 'accessibility' in the 1st quadrant. In the 2nd quadrant, 'price' and 'freshness' were shown as the factors. In the 3rd quadrant, 'easy to serve', 'familiar food menu', and 'consistent menu' were shown as the leading factors, and in the 4th quadrant, 'saving labor' was the only factor. Conclusion: Based on these results, the research concludes that with respect to developing HMR products, there is a high demand for low sodium, low calorie, small packaged products; thus, showing the need to develop various HMR products for customer satisfaction. Furthermore, it shows that there is a need to consider developing HMR products that can maintain freshness at an affordable price.

The impact of summer monsoon on water quality of the lower Nakdong River was evaluated during the summer(June∼August) in 1997. Several limnological variables were measured in the interval of 1∼3 day using an automatic monitoring system(Hydrolab Recorder^TM) to detect water quality changes caused by rainfall on one-hour basis. During the monsoon period(from late June to mid July), 5 times of major rainfall events of >50㎜ were recorded in the river basin. Dynamic changes of water quality were observed during the monsoon, and the first rainfall event(June 25∼27) had a significant influence on the water quality at the lower part of the river. All parameters were largely changed due to the first rain event, and the changed level was maintained until the end of monsoon period. Nutrient concentrations and turbidity increased and values of the other parameters were declined as a result of water dilution. This rainfall event, Changma, is a meteorological phenomenon caused by the East-Asian monsoon climate. The magnitude and frequency of the rainfall during the early monsoon play an important role in change of water quality and ecosystem characteristics of large river system.

최대 엔트로피 부스팅 모델을 이용한 영어 전치사구 접속과 품사 결정 모호성 해소

박성배(Sung-Bae Park) 한국정보과학회 2003 정보과학회논문지 : 소프트웨어 및 응용 Vol.30 No.5·6

최대 엔트로피 모델은 자연언어를 모델링하기 위한 좋은 방법이다. 하지만, 최대 엔트로피 모델을 전치사구 접속과 같은 실제 언어 문제에 적용할 때, 자질 선택과 계산 복잡도의 두 가지 문제가 발생한다. 본 논문에서는, 이런 문제와 자연언어 자원에 존재하는 불균형 데이터 문제를 해결하기 위한 최대 엔트로피 부스팅 모델(maximum entropy boosting model)을 제시하고, 이를 영어의 전치사구 접속과 품사 결정 모호성 해소에 적용한다. Wall Street Journal 말뭉치에 대한 실험 결과, 문제의 모델링에 아주 작은 노력을 들였음에도 불구하고, 전치사구 접속 문제에 대해 84.3%의 정확도와 품사 결정 문제에 대해 96.78%의 정확도를 보여 지금까지 알려진 최고의 성능과 비슷한 결과를 보였다. Maximum entropy models are promising candidates for natural language modeling. However, there are two major hurdles in applying maximum entropy models to real-life language problems, such as prepositional phrase attachment: feature selection and high computational complexity. In this paper, we propose a maximum entropy boosting model to overcome these limitations and the problem of imbalanced data in natural language resources, and apply it to prepositional phrase (PP) attachment and part-of-speech (POS) tagging. According to the experimental results on Wall Street Journal corpus, the model shows 84.3% of accuracy for PP attachment and 96.78% of accuracy for POS tagging that are close to the state-of-the-art performance of these tasks only with small efforts of modeling.

[Purpose] The main purpose of this current study is two-fold. Firstly, it attempts to develop a model to determine the true market value of Korean professional baseball players (hitters only) solely based on their athletic performances on the field. Secondly, it is to provide the evidential data for the market value of baseball players in Korea. [Methods] The statistical data and performance information were obtained from baseball almanac from KBO from 1997 to 2016. Seven hundred and ninety three players were included for data analysis. Principal component factor analysis was utilized to eliminate multicollinearity among 12 sabermetrics indices (OPS, GPA, SECA, TA, RC, RC/27, XR, ISO, PSN, sOBA, %OW, BABIP) and increase power of explanation of the proposed model with KMO(=0.77), p<0.001. [Results] The proposed model was successfully developed with YSalary = Years of Experience*921.5 + FA (free agent)*53528.9 + PHI(Power Hitter Index)*7313 + CHI(Contact Hitter Index)*5893.6. Furthermore, the proposed model explained 64.5% of variances of the market value for the Korean professional baseball players and proved to be statistically valid. [Conclusions] The newly developed model in this study was very helpful for us to identify the variables that affect the true market value of baseball players. It is expected that this model could make an important contribution in determining true market value of the baseball players in Korea. [목적] 이 연구의 목적은 크게 다음과 같은 두 가지로 나눌 수 있다. 첫째, 한국프로야구 선수들(타자들)의 성적에 따른 시장가치를 결정할 수 있는 모델을 개발하는 것이며 둘째, 이 모델을 기반으로 하여 선수들의 시장 가치에 대한 객관적인 근거 자료를 제공하는 것이다. [방법] 1997년부터 2016년까지 활약한 선수 중 각해당연도 규정에 따라 최소 타석 기준을 충족한 793명의 자료를 한국야구위원회위원회가 제공하는 연감의 데이터를 바탕으로 재구성 및 편집 과정을 거친 후 통계 분석을 하였다. 12개의 세이버메트릭스 지수들의 다중공선성을 제거하고 동시에 모델의 설명력을 높이기 위해 주성분 분석을 실행하여 강타자 지수 (PHI)와 교타자 지수 (CHI)를 얻었다. [결과] 선수들의 연봉에 영향을 미치는 경력(연수)과 FA의 유무를 독립변수로 하여 선형회귀분석을 하여 다음과 같은 모델을 얻었다. 선수연봉 = 연차*921.5 + FA유무*53528.9 + 강타자 지수*7313 + 교타자 지수*2197.3 + 5893 (단위: 만원). 제안된 모델은 한국프로야구 내 선수가치의 64.5%를 설명하는 것으로 나타났으며 통계적 유효성이 검증되었다. [결론] 본 연구를 통해 새롭게 개발된 모델을 통해 선수의 가치평가에 영향을 주는 변수들을 밝혀낼 수 있었으며 이러한 결과가 시장에 적용된다면 프로야구선수 가치평가 시장에 큰 공헌을 할 수 있을 것으로 기대한다.

박성배(Park, Sung-Bae Roger),이완영(Lee, Wan-Young),전홍권(Jeon, Hong-Kweon) 한국사회체육학회 2016 한국사회체육학회지 Vol.0 No.66

Since the notion of Sabermetrics was introduced into the business of baseball operations, several meaningful outcomes (i.e., win/loss prediction model and econometric indices of performances) have been developed and utilized in the past decade. As the salary amount of free agents (FA) baseball players skyrocketed, whether being FA athletes or not has become the most critical factor measuring their current and future market value in the baseball industry. Therefore, the main purposes of this current study are (1) to segregate FA and non-FA athletes into two groups and (2) to extract the meaningful factors which would eventually contribute to valuation of their market value, respectively. The performance records and salary information of total 3,343 former and current professional baseball players from 1997 to 2015 were obtained. 728 players were qualified and met the minimum conditions to be included in this study. The results included that XR (.30), SecA(0.30), batting average (0.29) were determined to be critical factors to affect market value for FA players while RC/27(0.47), homerun (0.27), age (0.11), and double hits (0.05) for non-FA players.

[결론] 첫째, 심리적 도박 심각도 지수에 영향을 미치는 요인은 직업의 유무, 직업의 안정성, 흡연 및 음주와 같은 생활 습관에 따라 심리적 중독 심각도 지수가 높았다는 점이다. 둘째, 행동적 도박 심각도 지수에 영향을 미치는 요인은 성별, 직업의 특성, 직업의 유무, 자기 통제에 대한 확신, 자기 향상에 대한 욕구 등이었다. PURPOSE This study aimed to a) develop suitable screening tools for identifying gambling severity in Korea and b) explore factors that affect the gambling severity index in order to prevent Korean sports betting users from easily falling into gambling addiction, thus providing practical and useful guidelines in this regard. METHODS This study examined Korean sports fans who had experiences of participating in sports betting (Sports Toto), a legal sports betting system in Korea. Toward this end, an online survey was conducted from May 10 to June 25, 2022. A total of 214 questionnaire results, excluding 23 who gave insincere and/or incomplete answers, were analyzed for normal distribution through skewness and kurtosis, and subscale scores were calculated after performing exploratory factor analysis and reliability analysis using Cronbach’s α. RESULTS A psychological gambling severity index and behavioral gambling severity index were developed based on a stepwise regression analysis, which was conducted using the demographic characteristics of domestic sports betting participants and their lifestyle habits (e.g., smoking and drinking, problem gambling severity index, self-control scale, and gambling expectation scale). CONCLUSIONS First, factors affecting the psychological gambling severity index were identified (having a job, job stability, and security) along with lifestyle habits (smoking and drinking). Second, gender, occupational characteristics, full-time employment, confidence in self-control, and desire for self-improvement were indicated as significant factors that influenced the behavioral gambling severity index.

박성배(Sung Bae Park),김현철(Hyun Chul Kim),박관규(Kwan Kyu Park),이상수(Sang Su Lee),박경대(Kyoung Dae Park),황은아(Eun Ah Hwang),이기태(Ki Tae Lee) 대한신장학회 2000 Kidney Research and Clinical Practice Vol.19 No.1

N/A Asymptomatic urinary abnormalities are one of the most frequent abnormalities in clinical nephrology. Between April 1981 and February 1999, we conducted retrospective follow-up studies of 159 patients with asymptomatic urinary abnormality that was proven by kidney biopsy, and evaluated their histologic findings and natural course. Mean age was 34.7 years old and sex ratio of male to female was 78: 81. They were divided into three groups according to the initial urinalysis findings' six patients with isolated hematuria, 33 patients with isolated proteinuria, and 120 patients with concomitant hematuria and proteinuria. The mean follow-up period was 35.5±30.5 months. In pathologic findings, 95 cases(59.3%) had IgA nephropathy, 27 cases(17.5%) had minor lesion, 12 cases(7.5%) showed focal and segmental glomerulo- sclerosis, 10 cases(6.3%) had membrannvs glomer-ulonephritis, 9 cases(5.6%) had mesangial prolifera- tive glomerulonephritis. Amyloidosis and thin base-ment membrane disease were seen in two cases, respectively. There were no specific correlations between morphologic patterns and degree of proteinuria. During the mean follow-up period, hematuria or proteinuria disppeared in 14%, persisted in 49%, and developed renal insufficiency in 21%. During the mean follow-up period, isolated proteinuria disappeared in 24%, persisted in 36%, and developed renal insufficiency in 21%. We conclude that the most common cause of asymptomatic urinary abnormalities was IgA nephropathy and early diagnosis through renal biopsy and management is needed to prevent or slow the progression to chronic renal failure.
