Allergic rhinitis is an IgE-mediated disease, leading to inflammation of the nasal mucosa. Typical symptoms of allergic rhinitis are nasal congestion, rhinorrhea, sneezing, and/or nasal itching. Allergic rhinitis is a major health problem worldwide that causes illness and disability in daily life, affecting social life, sleep, school, and work. The economic cost of allergic rhinitis is substantial. Management of allergic rhinitis can be categorized largely into ①allergen avoidance, ②pharmacotherapy, ③immunotherapy, and ④surgical treatment. Although the general consensus is that allergen avoidance should lead to an improvement of symptoms, it is nearly impossible to completely avoid all allergens in real life. The importance of allergen avoidance is that minimizing allergen exposure can decrease medication dosage. Pharmacotherapy of allergic rhinitis may include any of histamine antagonist, topical/oral corticosteroid, leukotriene antagonist, decongestant, mast cell stabilizer, and cholinergic antagonist alone or in combination. Oral and intranasal spray of these medications are the main routes of administration. Immunotherapy is the medical procedure that uses controlled exposure to known allergens to reduce the severity of allergic disease. There are two ways of administering this treatment: subcutaneous immunotherapy (SCIT) and sublingual immunotherapy (SLIT). Surgical treatment of the allergic rhinitis patient aims to resolve nasal obstruction by performing septoplasty or turbinoplasty.

In the fishery industry, digital innovation called the 4th industrial revolution is continuously spreading. The fishery industry is also in the process of changing jobs related to digital technology. The change and importance of digital innovation in the fishery industry should be identified. In order to convert the existing model in the fishery industry, a full-scale study should be conducted. In the changing environment of the paradigm shift, the fishery industry must also come up with a strategy to secure a competitive advantage. Strategies and operations for the growth and survival of the fishery industry must change along with the 4th industrial revolution. In order to improve the survival and profitability of the fishery industry, it is fundamentally important to introduce information technology and recognize its value. Because the speed of change is fast, the fishery industry is highly likely to go out of business. In order to solve the chronic problems of the fishery industry, the role of the 4th industrial revolution is necessary. The purpose of this study is to analyze the relationship between the environmental factors of the introduction of information technology in the fishery industry and the impact on the value perception of fishery development and profitability improvement. For the basic statistical analysis of the questionnaire, SPSS 22.0, a statistical package, was used. For hypothesis testing, concentrated validity and discriminant validity were verified using the structural equation package Smart PLS 2.0. Factors that determine the environmental factors of the introduction of information technology are divided into external environment of fishery, internal environment of fishery, and environment of public sector. The recognition of the value of fishery development was divided into opportunity capture and process improvement. A summary of the study follows. First, the environmental factors of the introduction of information technology in the fishery industry and the recognition of the value of the development of the fishery industry were partially adopted. Public sector environment and opportunity seizing did not have a significant effect. Second, the value recognition of the development of the fishery industry had a significant effect on profitability improvement. 수산업에서도 4차 산업혁명이라는 디지털 혁신이 계속적으로 확산되고 있다. 수산업도 디지털 기술과 관련된 직업군은 변화의 과정에 있다. 수산업에서 디지털 혁신의 변화와 중요성을 파악하여야 한다. 수산업에서 기존모델을 전환하기 위한 본격적 연구가 진행되어야 한다. 변화하는 패러다임 전환의 환경 속에서 수산업도 경쟁우위를 확보하는 전략을 도출해야 한다. 수산업의 성장과 생존을 위한 전략 및 운영은 4차 산업혁명과 더불어 변화하여야 한다. 이러한 수산업의 생존과 수익성 향상을 위해서는 기본적으로 정보기술도입과 수산업 발전의 가치인식이 중요하다. 변화의 속도가 빠르기 때문에 수산업도 도태될 가능성이 높기 때문이다. 수산업의 고질적인 문제를 해결하기 위해서는 4차 산업혁명의 역할이 필요하다. 본 연구는 수산업 분야에서 정보기술도입의 환경적 요인이 수산업발전의 가치인식과 수익성향상에 미치는 영향관계를 분석하는데 연구의 목적이 있다. 설문지의 기본통계분석을 위해 통계 패키지인 SPSS 22.0을 사용하였다. 가설검정을 위해 구조방정식 패키지 Smart PLS 2.0을 사용하여 집중타당성과 판별타당성을 검증하였다. 정보기술도입의 환경적 요인을 결정하는 요인으로 수산업의 외부환경, 수산업의 내부환경, 공공부문 환경으로 나누었다. 수산업 발전의 가치인식은 기회 포착과 프로세스 개선으로 나누었다. 연구의 요약은 다음과 같다. 첫째, 수산업에서 정보기술도입의 환경적요인과 수산업 발전의 가치인식은 부분채택되었다. 공공부문환경과 기회 포착은 유의한 영향을 미치지 못하였다. 둘째, 수산업 발전의 가치인식은 수익성 향상에 유의한 영향을 미쳤다.
