Background: Swallowing function deterioration is a common problem experienced by older adults worldwide. Many studies have been conducted to improve swallowing function in older adults; however, due to differences in intervention methods and study designs, it is difficult to draw a common conclusion. This study aimed to analyze trends and intervention methods in studies of swallowing function intervention for older adults conducted from 2010 to 2022, to establish a systematic approach for developing interventions to improve swallowing function in older adults and to provide evidence for this approach. Methods: Literature research was conducted for studies published between 2010 and 2022 that applied to swallow function interventions to adults aged 60 years or older. Databases including PubMed, Medline, RISS, Science On, KISS, and KCI were used. From a total of 1,164 articles searched using keywords, 20 articles were selected for final analysis. Results: The number of published articles steadily increased over time, and the intervention period was most commonly 6 or 8 weeks. The types of interventions included focused exercises to improve oral muscle strength in 12 articles and programs incorporating education, practice, and expert management in 8 articles. Among the focused exercises, tongue-strengthening exercises were most common in 4 articles. The evaluation variables for intervention effects were muscle strength evaluation, oral function evaluation, quality of life, and oral health and hygiene status. Muscle strength and oral function evaluations were statistically significant in focused exercise interventions, while the quality of life and oral health and hygiene status was significant in program interventions. Conclusion: This literature review is meaningful as a study that can be used to select the intervention period and program contents when planning an elderly swallowing intervention program.

Objectives : To compare the quality improvement of the abstracts of original articles, according to the revised manuscript format, of the Korean Journal of Preventive Medicine (Korean J Pre Med) was adopted in 1999. Methods : A total 63 abstracts for 1997, and 49 for 2001, were selected as the original articles from the Kor J Pre Med. This study was carried out by the separate-sample pretest-posttest design. The quality of the abstracts was measured by a checklist of Narine' evaluation criteria, and the other information related to the articles were also surveyed by e-mail and fax or telephone using a self-made Questionnaire, From the response rate, a total of 62 abstracts for 1997 and 49 for 2901 were finally analyzed. Results : The mean number of words in an abstract decreased from 285 in 1997, to 250 by 2001. The mean number of key words per abstract decreased from 3.9 in 1997, to 3.6 by 2001. The mean number of inappropriate usage of key words per abstract, by the MeSH standard, decreased from 1.9 in 1997, to 0.4 by 2001 Also, the overall mean score of abstract quality increased from 0.54 in 1997 to 0.61 by 2001. The range of scores for the abstract quality was better in 2001 ($0.40{\sim}0.77$) than in 1997 ($0.20{\sim}0.81$). From the multiple regression analyses of the 1997 and 2001 databases, the intervention of the manuscript format's revision, and the number of English words to the quality score of the .abstract, were the only statistically significant factors, Conclusions : In conclusion, the quality of abstracts in the Kor J Pre Med has improved since the revised manuscript format was adopted in 1999. The Korean Society for Preventive Medicine will continuously recommend proposals for more informative abstracts in their journal, and will evaluate the abstracts' content with quality criteria. Future studies should address these issues, and compare the quality of abstracts between different international and domestic journals.

Processing methods of heat treatment in milk has been developed to increase safety for the consumer by destroying pathogens that may be found in milk. Commercial pasteurization of milk in the market started in the late 1800s in Europe and in the early 1900s in the United States. In 1962, it became a requirement in Korea that all milk for sale should be treated by heat. Nowadays, heat treatment (pasteurization or sterilization) became mandatory for all milk products sold in all over the world. However, since 1987, there was a big debate about the heat-treatment of milk. Korea Society of Dairy Science and Technology (KSDST) complied the 10 scientific articles of milk heat-treatment into the book which titled "Effects of the heat-treatment on the nutritional quality of milk". Almost several hundred copies had been distributed at the symposium KSDST in 1989. Currently, no one was able to find these articles in anywhere including library etc. Thus, author decided to re-write that books in serials because these articles should be pass on their knowledge of milk science to the next generation of milk research.

Auditory scene analysis is defined as a listener's ability to segregate a meaningful message from meaningless background noise in a listening environment. To gain better understanding of auditory perception in terms of message integration and segregation ability among concurrent signals, we aimed to systematically review the size of auditory scenes among individuals. A total of seven electronic databases were searched from 2000 to the present with related key terms. Using our inclusion criteria, 4,507 articles were classified according to four sequential steps-identification, screening, eligibility, included. Following study selection, the quality of four included articles was evaluated using the CAMARADES checklist. In general, studies concluded that the size of auditory scene increased as the number of sound sources increased; however, when the number of sources was five or higher, the listener's auditory scene analysis reached its maximum capability. Unfortunately, the score of study quality was not determined to be very high, and the number of articles used to calculate mean effect size and statistical significance was insufficient to draw significant conclusions. We suggest that study design and materials that consider realistic listening environments should be used in further studies to deep understand the nature of auditory scene analysis within various groups.

Importance-Performance Analysis(IPA) holds the assumption that the degree of physical fulfilment of quality attributes and the satisfaction of that attribute is linear. Therefore, IPA can be applied to the traditional one-dimensional attributes, not to other quality elements such as attractive or must-be attributes. To overcome this problem, several articles introduced methods that integrate IPA into the concept of two-dimensional quality. However, these articles are rather conceptual focusing on the differentiation of quality attributes depend on quality elements in IPA. To provide empirical evidence of the dependent relationship between attribute importance and satisfaction in IPA, this study introduces a weighted importance approach and provides validation method using Bacon's priority model, a regression model. For this, the current research investigates 23 quality attributes of TV set for the results of Kano's model, which are adopted from Kim et al., and conducted a survey of 118 university students for the results of the importance/satisfaction and improvement priority. The result of the proposed approach shows better result than those using the conventional way, based on R-square of the regression model.

Objectives : The purpose of this study is to review which acupoints and meridians are selected to treat visceral pain in articles published in international journals and to investigate quality of reporting acupuncture intervention according to the STRICTA guidelines. Methods : Electrical and hand search were conducted in PubMed, EMBASE, MEDLINE, and Cochrane Library for acupuncture studies on visceral pain in human and animals. Reporting quality of intervention was evaluated using the revised STRICTA guidelines. Results : We included 51 articles (7 clinical studies and 44 animal studies) in this study. The most frequently adopted meridians and acupoints were Stomach meridian, Spleen meridian, Conception Vessel meridian, and ST36, CV4, SP6, LI4, PC6, SP9, ST25, ST37 in clinical studies. In animal studies, Stomach meridian, Conception Vessel meridian, Pericardium meridian and ST36, ST37, CV12, PC6 were most frequently used. Animal studies showed significantly lower quality of reporting compared to clinical studies. According to the analysis on the effect of year of publication of articles, announcement of STRICTA guidelines did not improve the quality of reporting for studies on visceral pain. Conclusions : These results suggest that both proximal and distal acupoints based on meridian theory were used to study the underlying mechanisms of visceral pain both in human and animal studies. Guidelines of acupuncture intervention reporting for animal study is necessary to improve the quality of evidence, and it will also allow us the integrative understanding of the mechanisms and clinical effects of acupuncture treatment in human and animal.
