In this study, keywords from representative online portal sites such as NAVER, Google, and Youtube were collected based on text mining analysis technique using TEXTOM to check the changes in the restaurant industry before and after COVID-19. The collection keywords were selected as dining out, food service industry, and dining out culture. For the collected data, the top 30 words were derived, respectively, through the refinement process. In addition, comparative analysis was conducted by defining data from 2018 to 2019 before COVID- 19, and from 2020 to 2021 after COVID-19. As a result, 8272 keywords before COVID-19 and 9654 keywords after COVID-19, a total of 17926 keywords, were derived. In order for the food service industry to develop after the COVID-19 pandemic, it is necessary to commercialize the recipes of restaurants to revitalize the distribution of home-use food products that replace home-cooked meals such as meal kits. Due to the social distancing caused by COVID-19, the dining out culture has changed and the trend has changed, and it has been confirmed that the consumption culture has changed to eating and delivering at home more safely than visiting restaurants. In addition, it has been confirmed that the consumption culture of existing consumers is changing to a trend of cooking at home rather than visiting restaurants.

최근 살인 사건의 살해도구에 관한 연구 - 칼을 중심으로 -
정석준,채종민,Jeong, Suk-Joon,Chae, Jong-Min 대한수사과학회 2006 대한수사과학회지 Vol.1 No.2
최근 살인사건의 실태를 보면 칼을 이용한 살인사건이 가장 많다. 살인을 음모하고 예견된 살인도 있지만, 순간적인 분노로 인한 우발적으로 저질러지기도 한다. 우발적인 범행에서 주변 가까이에 있는 가정용 칼을 범행에 사용하는 경우가 많지만 일상생활에서 칼의 위험성을 인식하는 경우가 드물다. 이에 전국에서 발생하는 살인사건의 범행방법 중 칼에 의한 범행에서 동기 분석과 함께 살해에 사용한 칼의 종류를 분석하였다. 그리고 칼에 대한 인식을 알아보고자 성인 남녀 500명을 대상으로 가정용 칼에 대한 21항목의 설문조사를 실시하였다. 그 결과를 일반 가정에서 사용하는 칼의 대부분이 칼끝이 날카로워 사실상 범행에 사용하기가 용이하였다. 그렇기 때문에 범인들이 칼을 휴대하기보다는 범행 장소에서 칼을 쉽게 구하여 범행에 사용하는 경우가 많다. 그리고 우발적인 살인의 경우에도 주방이나 식탁 또는 거실에서 칼을 쉽게 구할 수 있기 때문에 살인 사건이 더욱 빈발할 수 있다. 일반인의 칼에 대한 인식에서 칼의 위험도를 낮추기 위하여 칼끝을 둥글게 하자는 여론은 매우 높은 결과로 나타나지만 실제로 칼의 위험성에 대한 인식이 낮았다. 따라서 가정이나 가까운 사이에서 우발적 충동적인 살인을 예방하기 위하여 생활도구로 사용하는 칼도 위험한 물건으로 분류하여 인식전환과 함께 칼의 제작과 판매에 있어서 적절한 규제가 필요하다고 생각한다. 칼에 대한 인식을 새롭게 하여 가정에서 칼의 보관과 잠금장치의 필요성에 대한 홍보가 절실하다고 생각한다. I searched the recent murder cases for other criminal methods of homicides the monthly statistics of the local police agencies of the whole country, I found that there are many criminal cases where knives were used. Based on this finding, I decided to conduct my survey about kitchen knives. The statistics indicated more than five hundread male and female adults were reported to have committed murders. Of the 500 people, 21 used a kitchen knife to commit murder. This study showed that when people have a conflict, the kitchen knife is as a tool that can be easily changed into a weapon. If the points of the knife is round, more homicides could be avoided. If regulations were established, as we have with dagger when producing, selling or purchasing, I would assume that the number of the crimes with knives will be remarkably diminished. It is our responsibility to create a bill concerning regulatory standards in understanding the dangers of kitchen knives. We must immediately participate in active publicity campaigns.

The Effect of 0.5% Sodium Tetradecyl Sulfate on a Venous Lake Lesion
정석준,서영주,박은주,김철우,조희진,김광호,김광중 대한피부과학회 2008 Annals of Dermatology Vol.20 No.4
Background: A venous lake lesion is a venous ectasia that occurs on the exposed skin of elderly people. Although a number of therapies such as surgical excision, laser therapy, infrared coagulation, cryotherapy and sclerotherapy have been used to treat venous lakes, there is no guideline for treating this lesion. Objective: The purpose of this study was to determine whether 0.5% sodium tetradecyl sulfate (STS) is effective for the treatment of venous lake lesions. Methods: Twelve patients with venous lake lesions were enrolled In this study. After proper antiseptic preparation, 0.5% STS was slowly injected into each subject's lesion, and this was followed by immediate compression for 10 minutes. Results: After treatment, all of the patients' lesions cleared completely. The average number of treatments was 2.15±1.28. Two patients experienced mild side effects such as light pain and paresthesia, and these soon disappeared. There were no serious side effects reported during treatment. The mean follow up period was 29.58±13.48 months. Conclusion: We have demonstrated that sclerotherapy with 0.5% STS was quite effective for treating venous lake lesions, and this treatment caused no serious adverse effects.
