Purpose: Concerns about accelerated aging are regularly being discussed. This study analyzed the dietary status and nutritional intake of college students who are about to enter their 30s and 40s. We further suggest ways to eat healthily. Methods: Totally, 67 students attending Daegu Catholic University were provided with a three-day meal record and analyzed. Results: The average demographics of the subjects were as follows: age 23.2 ± 2.0 years, height 165.1 ± 9.0 cm, weight 65.4 ± 13.6 kg, and BMI 23.5 ± 3.9 kg/m². Overall, 76.3% of the subjects skipped breakfast. The food intake evaluation according to the food group intake pattern and the recommended number of servings determined that 38.3% of the subjects did not consume fruits and dairy products (GMVFDS = 111001), and both men and women lacked all food groups. Analysis of the nutrient intake state revealed lesser nutrient intake than the estimated energy need. Evaluation of the %RDA found that consumption of phosphorus was above the recommended amount, whereas all other nutrients were below the recommended amount. Men had a higher intake rate of phosphorus (p < 0.01), iron (p < 0.001), and sodium (p < 0.05) than women, whereas the intake rate of dietary fiber was higher in women (p < 0.05). Evaluation of the food intake by 22 food categories revealed that intake of regular grains was more in men than in women (p < 0.05) whereas women consumed significantly more mixed grains (p< 0.01). In protein foods, men consumed more meat (p < 0.01), while women consumed more eggs (p < 0.05) and beans (p < 0.05). Evaluating the fruit intake, juices were more frequently consumed by men than by women (p < 0.05). No differences were obtained in food intake and nutrient intake status according to obesity. Conclusion: Based on these results, there is an urgent requirement for attention and support for university cafeterias in order to induce changes in the eating habits of college students. Among other initiatives, this can be achieved by providing diet improvement programs and menus that consider food preferences.

Purpose: This study examines the effectiveness of personalized goal setting and smartphone-based nutrition counseling among adults in their 20s and 30s. Methods: Nutrition counseling was conducted for a total of 30 adults through a 1:1 chat room of a mobile instant messenger, once a week for 8 weeks. The first week of counseling included a preliminary online questionnaire survey and a dietary intake survey. Based on the results of the preliminary survey, 2 dietary goals were set in the second week and the participants were asked to record their achievements on a daily checklist. From the third week onwards, counselors sent feedback messages based on the checklist and provided information on dietary guidelines in a card news format every week. Post-counseling questionnaires and dietary intake surveys were conducted in the seventh week. Changes in dietary habits during the counseling were reviewed in the eighth week, followed by a questionnaire survey on the evaluation of the counseling process. Results: The nutrition quotient (NQ) scores and self-efficacy scores were significantly higher after nutrition counseling. The NQ scores of consumption frequencies of fruits, milk and dairy products, nuts, fast food, Ramyeon, sweet and greasy baked products, sugarsweetened beverages, the number of vegetable dishes at meals, and breakfast frequency were significantly higher after nutrition counseling. The intake of protein, vitamin A, thiamin, riboflavin, folate, calcium, and iron, and the index of nutritional quality of vitamin A, riboflavin, folate, calcium, and iron were higher after nutrition education. The participants were satisfied with the nutrition counseling program and the provided nutrition information. Conclusion: Personalized goal setting and smartphone-based nutrition counseling were found to be effective in improving the quality of diet and self-efficacy in young adults. Similar results were obtained in both the underweight/normal weight and the overweight/obese groups.

This study was conducted to confirm the utilization of Pleurospermum camtschaticum root extract as an organic agricultural material. Antioxidant activity of P. camtschaticum root extract, closely related to antibacterial activity, increased in a dose-dependent manner. In mycelial growth inhibitory activity, 100% P. camtschaticum root extract supressed over 70% for Colletotrichum coccodes and over 68% for Colletotrichum dematium. In the pepper fruit anthracnose development test, the size of the lesion decreased in a dose-dependent manner, which showed the same tendency as the previous results in inhibitory activity on mycelial growth. In the pepper seed germination and red pepper growth promotion test of P. camtschaticum root extract, oposite results was confirmed. The lower the concentration, the more the seed germination and growth promotion effects were shown. The phenol content of pepper leaves was also measured after pepper growth promotion test have been completed. The phenol content related to antibacterial activity increased in all treated groups compared to the untreated group. Therefore, the results of this study showed the possibility of development as an organic material.

A delta is a depositional landform that is formed when sediment transported by a river is deposited in a relatively low-energy environment, such as a lake, sea, or a main channel. Among these, a delta formed at the confluence of rivers has a great importance in river management and research because it has a significant impact on the hydraulic and sedimentological characteristics of the river. Recently, the equilibrium state of the confluence area has been disrupted by large-scale dredging and construction of levees in the Nakdong River. However, due to the natural recovery of the river, the confluence area is returning to its pre-dredging natural state through ongoing sedimentation. The time-series data show that the confluence delta has been steadily growing since the dredging, but once it reaches a certain size, it repeats growth and retreat, and the overall size does not change significantly. In this study, we developed a model to explain the sedimentation-erosion processes in the confluence area based on the assumption that the confluence delta reaches a dynamic equilibrium. The model is based on two fundamental principles: sedimentation due to supply from the tributary and erosion due to the main channel. The erosion coefficient that represents the Nakdong River confluence areas, was obtained using data from the tributaries of the Nakdong River. Sensitivity analyses were conducted using the developed model to understand how the confluence delta responds to changes in the sediment and water discharges of the tributary and the main channel, respectively. We then used annual average discharge of the Nakdong River's tributaries to predict the dynamic equilibrium positions of the confluence deltas. Finally, we conducted a simulation experiment on the development of the Gamcheon-Nakdong River delta using recorded daily discharge. The results showed that even though it is a simple model, it accurately predicted the dynamic equilibrium positions of the confluence deltas in the Nakdong River, including the areas where the delta had not formed, and those where the delta had already formed and predicted the trend of the response of the Gamcheon-Nakdong River delta. However, the actual retreat in the Gamcheon-Nakdong River delta was not captured fully due to errors and limitations in the simplification process. The insights through this study provide basic information on the sediment supply of the Nakdong River through the confluence areas, which can be implemented as a basic model for river maintenance and management.

The fire blight caused by Erwinia amylovora (Ea) was first reported in 2015 in Korea, and the disease has rapidly spread to 22 regions until 2021. In Korea, all host plants in the apple and pear orchards where fire blight occurred should be eliminated and buried by the Plant Protection Act. To prevent the spread of the disease, all burial sites were prohibited from planting the new host plants for the next three years. To confirm the eradication efficiency of Ea and the reoccurrence of fire blight, the surveillance facilities were established on three burial sites from 2019 to 2020 in Anseong-si, Gyeonggi-do, and Chungju-si, Chungcheongbuk-do. As host plants, five apple trees of fire blight-susceptible cultivar 'Fuji', were planted in each facility. All facilities were enclosed with fences and nets and equipped with two CCTVs, motion sensors, and several other sensors for recording weather conditions to monitor the environment of the sentinel plants in real-time. The sentinel plants were checked for the reoccurrence of fire blight routinely. Suspicious plant parts were collected and analyzed for Ea detection by loop-mediated isothermal amplification polymerase chain reaction and conventional polymerase chain reaction. Until November 2022, Ea has not been detected in all sentinel plants. These results might support that the burial control of infected plants in soil works efficiently to remove Ea and support the possibility to shorten the prohibition period of host plant establishment in the burial sites.

Because of the spread of smartphones due to the development of information and communication technology, online shopping mall services can be used on computers and mobile devices. As a result, the number of users using the online shopping mall service increases rapidly, and the types of products traded are also growing. Therefore, to maximize profits, companies need to provide information that may interest users. To this end, the recommendation system presents necessary information or products to the user based on the user's past behavioral data or behavioral purchase records. Representative overseas companies that currently provide recommendation services include Netflix, Amazon, and YouTube. These companies support users' purchase decisions by recommending products to users using ratings, purchase records, and clickstream data that users give to the items. In addition, users refer to the ratings left by other users about the product before buying a product. Most users tend to provide ratings only to products they are satisfied with, and the higher the rating, the higher the purchase intention. And recently, e-commerce sites have provided users with the ability to vote on whether product reviews are helpful. Through this, the user makes a purchase decision by referring to reviews and ratings of products judged to be beneficial. Therefore, in this study, the correlation between the product rating and the helpful information of the review is identified. The valuable data of the evaluation is reflected in the recommendation system to check the recommendation performance. In addition, we want to compare the results of skipping all the ratings in the traditional collaborative filtering technique with the recommended performance results that reflect only the 4 and 5 ratings. For this purpose, electronic product data collected from Amazon was used in this study, and the experimental results confirmed a correlation between ratings and review usefulness information. In addition, as a result of comparing the recommendation performance by reflecting all the ratings and only the 4 and 5 points in the recommendation system, the recommendation performance of remembering only the 4 and 5 points in the recommendation system was higher. In addition, as a result of reflecting review usefulness information in the recommendation system, it was confirmed that the more valuable the review, the higher the recommendation performance. Therefore, these experimental results are expected to improve the performance of personalized recommendation services in the future and provide implications for e-commerce sites.

This paper take a media archaeological approach to cinema transformed into a narrative medium during its transitional period, 1903-1915. To accomplish this, I will explore the question of as which narrative medium cinema was imagined and also how it was institutionalized as a narrative medium with authorship. I will explain that the imaginary and real ideas and changes on cinema resonated with each other on the foundation of its technological aspects such as indexicality, 23 frames/sec. and montage. It was during the transitional period that cinema was transformed from a medium representing spectacle to a medium of narration. The establishment of the American film copyright law in 1912 was an institutional, real outcome from the contemporary understanding of cinema as a narrative medium. At the same time, various ideas emerged that led to imagining of cinema as a complete narrative medium, incomparable to any other. From a media archaeological perspective, the imaginary ideas of media resonate with their actual course of development. These imaginary ideas are not just imaginary, but rather reflect the contemporary desire for the medium. This paper looks into the transitional period based on this media archaeological point of view. To this end, this paper will briefly introduce the notion of media archaeology as a media theory and then discuss Eric Kluitenberg's concept of 'an archaeology of imaginary media' and its methodologies. Second, it will explore literary and cinematic imagining of cinema as a powerful medium of storytelling, while discussing the ways in which cinema's technological characteristics played a decisive role in these imaginings. Also to show the techno-deterministic role of cinema in the real world, this paper will explore how its technological characteristics were considered as an important element in the processes through which America's first motion picture copyright was institutionalized in 1912 after two historical copyright cases: one is Edison v. Lubin in 1903 and Kalem v. Harper Brothers in 1909. Ultimately, this paper will lead us to an understanding of the history of cinema as a medium and its developments in more multi-layed way, as communication between the real and imaginary, and give us perspectives toward what cinema is.

Objectives : The purpose of this study is to investigate the characteristics of patients referred for delirium and depressive disorder and to find direction of improvement of consultation-liason psychiatry in general hospital. Methods : We performed a retrospective computed chart review of the 4,966 inpatients hospitalized at Konkuk University Hospital who were referred to the Department of Psychiatry from August 1, 2005 to December 31, 2011. Results : Depressive disorder shows the order of frequency of consultation type Parallel-Complementary-Mending. Delirium shows the order of frequency of consultation type Mending-Parallel-Complementary. When comparing 'follow up consultation' and 'without follow up consultation' group within the depressive disorder, the proportion of men in the 'follow up consultation' group was higher. In the analysis of the consultation type, the 'follow up consultation' group showed the order of consultation type Parallel-Mending- Complementary, and type Parallel-Complementary-Mending in the 'without follow up consultation' group. When comparing 'follow up consultation' and 'without follow up consultation' group within the delirium, the proportion of the surgical field in the 'follow up consultation' group was higher. In the analysis of the consultation type, both group showed the order of consultation type Mending-Parallel- Complementary. Conclusions : Doctors in each department and psychiatrists should pay attention to delirium symptoms that may occur in surgical inpatients and preventive measures should be taken. Screening tests should be conducted in medical patients to properly evaluate coexisting psychiatric diseases. Risk factors of Delirium and Depressive disorder should be identified from the time of hospitalization, and actively discussing treatment plans and early interventions could improve the quality of medical services.

This paper aims to study on conceptual suitability or unfitness of Silhak(實學). It is general that by criticizing Chujahak(朱子學) or beyond the limitation of Seonglihak(性理學), Silhak has developed practical tendency to reforming the society in the middle and end of Chosen Dynasty, related to the context of Korean national reflection in modern times. However, it is unfortunate to be understood. As presented in Chosenwangjosillok(『朝鮮王朝實錄』), there has been a few usages in the term 'Silhak'. In short, it was different from its contemporary meaning. At that time, it was usually used to have the meaning of Gyunghak(經學), compared to Sajanghak(詞章學), or rarely, of 'the true study' or 'the practical study'. Therefore, it is to claim that its conception has been manipulated or exaggerated very seriously. Since 1930s, in particular, its conception has been misused in interpreting works of Jung Yak-Yong by some scholars, such as Jung In-Bo, Moon Il-Pyung and An Jae-Hong, who tried to apply the term to overcome the Japanese colonial era symbolised as modernity based on the future life of Korea. Even though their attempt has led to have crucial discussions on the conceptions of Silhak, it has an unnecessary result that there has been a new and totally different understanding of Silhak in South Korea, North Korea, China, Japan, etc., which means that the unsustainable conception of Silhak has been one of major problems in studying of Silhak. To give an practical solution, I would try to make sense of 'time spirit' whose scholars studied Silhak in the middle and end of Chosen Dynasty. A problem, however, is that a scholar group in the name of Bukhakpa(北學派) had certain links and bonds. This is because many scholars studying of Silhak were usually features out of the main stream, which made them it difficult to form any various groups. That is to say, it seems to be natural that they have dreamed of utopian imaginations less than of overlapping points in reality. To sum up, it would be concluded at least that any approach to human lives and thoughts in the given conceptions of Silhak, e.g. ethical thoughts of Silhak, enables us to be indifferentiated to take its true meaning and time spirit of Chosen Dynasty. To be disenchanted of its social roles in Chosen Dynasty, fundamentally, it should be escaped from the wrong net of illusions and sings in understanding Silhak in certain eclectic steps.

대순사상은 인간의 행위와 정신적 틀, 즉 몸과 마음을 닦고 세상을 다스리며 백성을 평안하게 하는 도리를 설파하고 있다. 우주 공간의 질서와 깊은 연관을 맺는 이러한 도리는 인간 자신의 인지(認知)와 심신 수양의 내용을 포함하며, 사람이 사회와 우주자연과의 관계를 어떻게 처리해 나갈 것인지에 관한 문제도 다루고 있다. 따라서 대순사상을 인문이라는 관점에 입각하여 분석해 볼 필요가 있다. 이탈리아에서 시작된 서양의 인문주의와 비교해 볼 때, 중국 전통의 인문정신은 인류 개체의 창조력과 그 성과를 인정하고, 인격적 수양과 개선을 주장하며, 사회의 조화를 강조하는 한편, 인류가 반드시 천지인의 조화로운 관계 속에서 개체와 전체의 생존을 파악해야 함을 강조한다. 이러한 인문정신은 『전경』에서도 찾아볼 수 있다. 그 하나가 모악산과 단주(丹朱)에 대한 서술인데, 모악산은 산 즉 '간'(艮)괘이며 단주는 적색에 상응하니 곧 '리'(離)괘가 된다. 이 두 괘가 서로 조합하면 '비(比)'괘가 되며, 『주역』의 비괘와 연관하여 서로 간의 모순을 없애고, '바둑'을 두는 기법을 거울삼아 심성을 다스리며, 인격을 완성하고, 인신이 조화를 이루도록 하며, 사회를 안정시킬 것을 말한다. 대순 신앙의 최종 목표는 지상천국을 건설하는 것인데, 이런 목표를 실현하기 위해서는 인격수양을 그 출발점으로 삼아야 한다. 인격수양의 목표는 바른 도인이 되기 위한 것이며, 이를 위해서는 수도 공부를 해야만 한다. 수도는 춘추시기 노자 이래로 유구한 문화적 전통을 지닌 것이지만, 대순진리회는 한국사회 역사의 경향과 현실의 필요에 부응하여 수도 이론을 새롭게 수립하였다. 이를 살펴보면, 대순진리회는 수도자가 '성(誠), 경(敬), 신(信)'에 힘쓰는 품격 함양을 매우 중시한다. 또 도인들이 가정의 화목에 힘써야 하며, 솔선수범하는 도인으로서 사회의 모범이 되어야 한다고 말한다. 이렇게 볼 때, 대순진리회는 '인도'(人道)를 함양함을 강조하고 있으며, 이것은 전통적인 유가에서 말하는 '수신, 제가' (修身, 齊家)의 정신과 그 의미가 맞닿아 있다. 또한 중국 도교의 '선도(仙道)를 이루고자 하면 먼저 인도(人道)를 행하라'는 사상적 취지와도 일치한다. 대순진리회에서 수도의 최종 목표는 도통이다. 도통은 수도자가 매우 높은 경지에 이르게 되었을 때 가지는 특수한 능력과 정신의 경지이다. '도통'에 대한 기록은 『장자·제물론』, 『문자』의 「부언편>(符言篇) 등에서 찾아볼 수 있는데, 대순진리회가 말하는 도통은 중국의 도가 전통에 보이는 도통과도 연관되지만 강한 인륜수양(人倫修養)적 특색을 지니고 있다는 점에서 차이가 있다. 이것은 대순진리회가 가지는 중요한 인문적 함의라 하겠다. 대순진리회는 수도 공부로써 광제창생·보국안민·지상천국건설의 사회적 이상을 실현하고자 한다. 조화로운 사회적 관계를 수립하기 위한 토대는 대순진리회의 종지 첫 번째인 음양합덕이다. 음양합덕은 대순진리의 인문 취지의 이론적 기초를 형성하는 사상이다. 음양합덕의 철학적 사고는 종지 두 번째인 신인조화(神人調化)의 이상으로 이어진다. 신인조화는 『상서·순전』(尙書·舜典)의 신인이화(神人以和)에서 그 사상적 연원을 찾아 볼 수 있다. 다만 신인이화가 율려 조화의 '결과'를 표현한 것이라면, 신인조화에서 중시하는 것은 '과정'이며 인간과 신의 상호작용이라는 점에 그 특징이 있다. 신인조화를 이루기 위해서는 공부를 해야 하며, 그 배후에는 인본(人本)의 사상이 깃들어 있다. 그것은 종지 세 번째인 '해원상생'의 내용에서 더욱 명확하게 드러난다. 신인조화가 인간과 신의 관계를 조화롭게 하는 것을 말한다면, 해원상생은 인간과 인간의 관계를 조화롭게 하는 것을 말한다. 또 다른 한편으로는 긴 역사의 과정 속에서 맺힌 원을 풀어 우주의 기운을 잘 통할 수 있게 하고 인간 사회의 정상적인 교류를 이루도록 한다. 이러한 내용은 사회적인 인문적 관심과 배려를 다분히 포함하고 있는 것이다. 대순진리회의 종지 네 번째인 도통진경은 수도의 가장 높은 경지를 말하는데, 이러한 이념은 노장 일파의 도가 학자들이 말한 순박한 본성으로 회귀하자는 정신에서 그 원류를 찾을 수 있을 것이다. 또한 이는 한진(漢晉)시대 이래 중국 도교가 추구했던 '진경' 의 의미와도 합치된다. 그러나 시대와 환경이 다름으로 인해, 대순진리회의 '진경'은 사회생활의 의미까지 내포한다. 비록 대순진리회의 경전이 인본(人本)을 명확히 밝히고 있지는 않으나, 대순진리회의 요의(要義) 중 하나인 인존사상은 대순진리회의 인문정신을 말해주는 것이다. 인존사상의 직접적인 기능은 평안(平安)으로서 삶을 이롭게 하는 것이다. 대순진리회는 우주대원의 진리를 '도'라 하였는데 이러한 '도'는 중국의 도가에서 말하는 '도'와 동일하며, 여기에는 '안(安)'의 의미가 포함되어 있다. 대순진리회의 신조 중 '안심', '안신'은 마음을 정(靜)하게 하고, 몸을 편하게 하는 것으로 볼 수 있지만, 심신의 공포와 두려움을 떨쳐내어 안전과 보호를 얻는다는 의미도 있으므로 결국 평안이 전제가 된다. 이렇듯 대순진리회에서는 '평안에 대한 희구'를 근본으로 하여 신앙인들이 열심히 수도에 정진하고 있다. 대순진리회가 인류 평안을 기본으로 하는 종교라는 점에서, 반드시 세인들의 환영을 받을 것임을 믿어 의심치 않는다.
