2012년 기준 대한민국은 OECD 국가들 중 연간 노동시간이 3위로 집계되었다. 직장인들의 과도한 업무 스트레스는 그들의 여가생활에도 막대한 영향을 미치고 있다. 대부분의 20~30대 직장인들은 취미를 가지고 있지만, 이를 활용할 시간과 정보, 공간이 부족하다. 본 연구는 바쁜 직장인들의 여가생활을 활성화하기 위해 새로운 커뮤니티 서비스를 제안하는데 목적이 있다. 연구방법으로는 1차로 문헌연구를 통해 직장인들의 업무실태를 조사하였고, 2차로 SNS 유형별 분석을 통해서 직장인 여가생활 커뮤니티에 적합한 유형을 제시하였다. 3차로 서비스 디자인 방법론인 더블 다이아몬드 디자인 프로세스 모델을 적용하여 발견, 정의, 개발, 전달인 4단계를 거쳐 복합형 SNS ‘Mohano’를 기획하였다. 이와 같은 기준으로, 사용자들이 다양한 취미나 관심사에 따른 게시물이나 정보를 공유할 수 있고, 취미가 같은 사람과의 만남을 제공함으로써 직장인들이 유용한 여가 시간을 보낼 수 있다. 이러한 결과를 통하여 직장인들의 여가생활 커뮤니티 활성화를 위해 필요한 사항들은 다음과 같다. 첫째, 사용자가 원하는 필요한 정보나, 인간관계를 제공할 필요가 있다. 둘째, 폐쇄형과 개방형의 장점을 지닌 복합형 SNS로 사용자의 개인정보 보안에 대한 시스템을 개선함으로써, 신뢰성 높은 서비스를 제공할 수 있다. 셋째, 콘셉트 ‘circle in’을 토대로 기획된 ‘Mohano’는 다음 사용성 평가 후, 더 나은 가이드라인을 제시가 필요하다. 향후 본 연구를 바탕으로 앞서 제시된 커뮤니티 서비스를 통하여 직장인들의 여가생활이 향상되길 기대한다. In 2012, Korea has been announced as a third-place for the highest working hours of workers in OECD countries. Their stressful and excessive work incredibly affects on their leisure life. Most of workers in 20’s to 30’s have their own interests, however, they do not have enough time, information, and spaces for the hobbies. This study indicates the suggestion on the new community service in order to vitalize the leisure life for busy workers. According to the analysis, at first, the study investigates the business realities in Korea throughout reference research. Moreover, it suggests a specific form which is appropriate for the leisure community of workers in consideration of the analysis for each form. After that, the hybrid SNS called ‘Mohano’ is designed with four phases of ‘Double Diamond Design Process’ including discover, define, develop, and deliver in methodology of service design. Following the process, users can share posts and information about several tastes or interests and the workers can spend valuable leisure time as it provides a meeting with people who have similar tastes. As a result, the necessary conditions for vitalizing a leisure community are mentioned below. First, it has to provide information and human relationships as the users desire. Furthermore, the hybrid SNS offering advantages of open SNS and close SNS provides reliable service as improving the security system on personal information which users own. Depended on the concept ‘circle in’, finally, the application ‘Mohano’ which was designed with the study requires a guideline after serviceability evaluation later on. Based on the study, from now on, it is eagerly anticipated that the leisure life of workers will be advanced through the community service mentioned above.

By using the ${\beta}$-tyrosinase of Citrobacter freundii KCT2006, which was cloned and overexpressed in Escherichia coli, 3,4-dihydroxy phenyl-L-alanine (L-DOPA) was synthesized efficiently from pyrocatechol, sodium pyruvate, and ammonium acetate. Optimal temperature and pH for the reaction were determined to be about 18$^{\circ}C$ and 8.5, respectively. The effects of substrate concentrations were also examined at different concentrations of ammonium acetate, sodium pyruvate, and pyrocatechol. Ammoniumacetate and sodium pyruvate increased the reaction rate until the concentrations reached to 300mM and 50mM, respectively. Although pyrocatechol showed the optimal concentration at 20mM, it was controlled between 20mM and 50mM to avoid the depletion of substrate during the enzymatic synthesis. Meanwhile the synthetic rate was improved about 20% when ethanol was included in the reaction solution. Based on above results, a reaction medium for the productin of L-DOPA was prepared and incubated with 1 unit/ml of ${\beta}$-tyrosinase. Pyrocatechol and sodium pyruvate was added to the reaction solutin intermittently to avoid the substrate depletion during the enzymatic reaction. After 24 hour of reaction, 31.6g/l of L-DOPA was accumulated in the reaction solution as soluble and precipitated ones and the conversion yield was about 85.2%.
