This paper aims to provide an analysis of articles in major tourism journals in Korea in order to identify recent trends in tourism experience research. To achieve this goal, this study conducted content analysis on total 228 research articles published in five major tourism journals in KCI index from 2000 to 2017 based on Ritchie & Hudson(2009)'s five experience research categories-conceptualization, experience behavior, methodologies, types of experiences, and managerial concerns. This study found that experience research has evidently increased since 2000 but experience research in Korea takes up a small portion of overall tourism research, compared with international tourism journals. Also, the result also indicated that experience behavior research is significantly predominant and research themes are highly limited in comparison with international tourism journals. Furthermore, it is found that a few journals lead experience research. Finally, suggestions for future research are discussed based on the results.

Mesoporous titanium dioxide (TiO_2) thin films were prepared using poly(vinyl chloride)-graft-poly(N-vinyl pyrrolidone) (PVC-g-PVP) as a templating agent via sol-gel process. Grafting of PVC chains from PVC backbone was done by atom transfer radical polymerization (ATRP)technique. The successful grafting of PVP to synthesize PVC-g-PVP was checked by fourier-transform infrared spectroscopy (FT-IR) and gel permeation chromatography (GPC). The carbonyl group interaction of PVC-g-PVP graft copolymer with TiO_2 was confirmed by FT-IR. The porous morphologies of the TiO2 films genereated after calcination at 450oC was characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The mesoporous TiO2films with 580 nm in thickness were used as a photoelectrode for solid state dye sensitized solar cell (DSSC) and showed an energy conversion efficiency of 1.05% at 100 mW/cm^2.

본 논문은 인증서를 기반으로 한 SSO(Single Sign-On)를 구현함에 있어 LDAP(Lightweight Directory Access Protocol)의 DN(Distinguished Name)과 속성(Attribute)을 지정함에 따라 다양한 응용서비스들을 수용할 수 있는 데이타 구조를 설계하였다. 조직의 인사데이타를 바탕으로 LDAP 데이타를 구축하고, 수시 변경되는 자료에 대하여는 연동에 의한 지속적인 자동수정 기능을 적용하였다. 또한 인증서 발급을 위해서 PKI(Public Key Infrastructure) 기반의 CA(Certificate Authority) 서버를 적용하였으며, 인증통신을 위한 데이타 암호화는 SSL(Secure Socket Layer) 기반의 SHTTP(Secure Hyper Text Transfer Protocol)을 적용하였다. This paper gives a comprehensive overview of the SSO solution design on the intranet. SSO described in this paper is based on LDAP, PKI and CA. We designed the data structure to hold many various application services by changing the attribute and DN of LDAP DB. We built LDAP DB using the employee records stored in our organization database. LDAP DB is routinely updated from the database. CA Server that depends on PKI is used to issue the certificates. SHTTP based on SSL is used to protect the data between certificate server and the intranet users.
