The purpose of this research is to develop elements of place branding and correspondent evaluation indicators for place brand strategy making, analysis and its evaluation. First, I criticise that previous research employed unclear and limited evaluation elements. I then suggest an plausible evaluation system and evaluation indicators through a theoretical proof for place branding under the concept of place-based value. Interviews with specialists for case evaluations were carried out in an effort to approve the plausibility of this suggested evaluation system. As an extension, a direction is suggested for a general and effective place branding that would satisfy a diversity of places, which could hopefully contributes for the development of future city brand and marketing evaluation criteria. Creating a specialized place brand requires precise understanding and evaluation on the place characteristics that should directly contribute to the strategy making based on the situatedness suggested by the place which meets an appropriate place branding category. In addition, a successful place branding requires active and effective communication among the participating members of interest and sustainable maintenance systems.

The study aimed to explore media use by digital natives in Korea. To date, Korea is a country that has both the highest level of digital natives and fastest Internet access in the world. The study also intended to deeply understand the simultaneous activity use of different media and determined the characteristics of Korean digital natives. Based on Korea Media Panel Data for 2015, analyses of the digital natives' traits of time-space, media use, and simultaneous use of media were made through a statistic multi-correspondent method. The results showed that spatial attribute and media use of digital natives are homogeneous in pattern and the degree of simultaneous use of media seems to be limited in type. Moreover, the study suggested the new concept of digital natives' media use and the need for various studies showing the relationship between media use and the Internet generation.

Phenomena induced by waves, such as overtopping, sediment transport, vibration/fluctuation and destruction of structures are highly influenced by the directionality of wave propagation. These phenomena are often dominated by non-linearity, and so hydraulic model experiments are widely adopted for stability analysis rather than numerical modeling, Thus, stability ofrubblc mound breakwaters(RMB) due to wavc directionality was experimentally investigated in this study. The incident wave angle $30^{\circ}$ was found more risky on the damage rate of RMB under directional regular waves, and the incident wave angle $40^{\circ}$ was found relatively risky under directional irregular waves. These results clarified the wave directionality effect on the stability ofRMB, These facts were found correspondent to the occurrence of the peak between $20^{\circ}$-$40^{\circ}$ with the directional frequency distribution of lIlO maximum water particle velocity.

In this paper, we propose the fast and secure binding update protocol as handoff or handover in the micro and pico environment based on mobile IPv6. The nodes or routers on participating in this protocol generate their addresses from cryptographically generated addresses (CGAs) method unlike previous address generation method. The mobile node (MN) includes in home network or home link has limited power and computational abilities. So the home agent (HA) of the MN executes key agreement protocol with the correspondent node (CN) on behalf of the MN. The CN then creates a ticket on including session key, lifetime of ticket. and so on. It then transmits it to the MN via the HA of the MN. The ticket is used to communicate directly between the MN and its CN. In performance analysis, we analyze security of proposed binding update protocol under various attack scenarios and efficiency by comparing proposed protocol with prior binding update protocols. Finally we make a conclusion of this paper and present future works.

This paper presents the interrelationship between undrained static and cyclic shear behavior. Laboratory works were performed through the undralned static and cyclic triaxial test using Nak-Dong River sand. And static triaxial test involved the triaxial extension test for comparison with cyclic shear behavior Cyclic triaxial test was performed with a variety of combination conditions of initial static shear stress $(q_{st})$ and cyclic stress $(q_{cy})$. In this result, the stress path of cyclic shear behavior was correspondent with static shear behavior passing the critical stress ratio (CSR) line because of the development of flow deformation. After that, a failure occurred according to failure line (FL) of static shear behavior. The stress path of cyclic shear behavior showed essentially the same with static shear behavior, although it appears a little different in test method.

This study aims to demonstrate how well SCM analysis, which indicates social cognitive map of categorizing peer subgroups of elementary school students, corresponds with that of teachers. To do this, the subject of this study includes two classes of the 3rd and the 5th grade students in D elementary school in B-gu, Busan city. Over 30 students of each gender in each grade were surveyed with social network questionnaires to collect data. The result of the social network survey was analyzed by SCM 4.0 program to categorize peer subgroups within each class. The categorized peer subgroups were reported to the class teacher. Based on the report, the class teachers observed peer subgroups in classes. After the teachers observed and categorized the students into several peer groups, an analysis was conducted to compare the peer subgrouping by students with that by teachers. The result showed the two were 80% correspondent to each other regardless of gender and grade. If interobserver reliability stays within the range of 80-100%, it is considered reliable. And this leads to the conclusion that peer subgrouping by students' cognition and that by teachers' observation can be regarded quite corresponding. In conclusion, peer subgrouping through SCM is significant when peer subgrouping Korean children, and it appears to be more significant when analyzed considering different variables including gender and grade. Peer subgrouping by girls is shown to be more accurate than that by boys.

Chemical and Pb isotope analysis were performed in order to determine the origin of bronze artefacts excavated from the Inyongsaji site in South Korea. The result of ICP-MS shows that they are tin bronzes in which lead was not intentionally added during production. Pb isotope data analyzed by TIMS are plotted in the southern region of Korea and China of the distribution map drawn by Mabuchi(1985). On the other hand, the identical isotope data are plotted in the Taebaek basin and the Olcheon metamorphic belt correspondent to zone2 and zone3 respectively. It is believed that the isotope data on the tin bronzes which have very low lead content can be used to trace the origin of copper ore rather than those of either lead or tin ore. Pb istope analysis allows diverse interpretation as it can be applied to any object containing trace amounts of lead. In addition, accumulation of isotope data as well as further studies will improve reliability of the provenance studies.

Previously two papers dealing with YoungSu(against the meridian course and following the course of the meridian) Acupuncture were published by our group. Here we are reporting the further analysis of YoungSu and WonBang(by twisting and rotating the needle) acupuncture methods. It is very important to understand objectively the Qi variation induced by the reinforcing-reducing manipulation method in the acupuncture therapy. We decided the medical treatment by utilizing the PyongChi Method (a kind of method to figure out the way of treatment by observing the unbalanced state of five phases). The Qi variation in the meridian treated by YoungSu and WonBang, the recovery of five phases deviation were measured by choosing single acupoint instead of complex acupoints. By using Youngsu and WonBang, we increased or decreased the Qi of the phase which caused the unbalanced state. We observed whether the Qi of the treated meridian can be increased and if the state of unbalance can be recovered. To achieve the effect of reinforcing-reducing, we needed a correct choice of treating method and a selection of a proper meridian in advance. This study was carried out by adding another way of acupuncture from the previous paper. We discovered that the effects of reinforcing-reducing by each manipulation method could be superposed each other when two counteracting Youngsu and WonBang methods were treated at the left and the right side of human body which was correspondent with our previous paper. We found that the Qi variation of the treated meridian, which was induced by Youngsu and WonBang, was linearly proportional to the reduction of five phase deviations. The slope of Qi variation was almost similar (y = -0.413x - 0.138) as that of previous paper (y = -0.266x - 0.038, Y = -0.446x - 0.079). It is assumed that the addition of other basic methods on the top of reinforcing-reducing manipulation method would magnify the effect of acupuncture.

This study aims to examine the attitudes toward online advertisement targeting YouTube content users and to present implications for the direction and regulation of personal media broadcasting advertisement. The study used the data from 'Awareness of On-line Ads and Blocking Tools' conducted by the Korea Press Foundation in 2020. For the statistical analysis, correspondent analysis was employed. The main results followed as: women tended to perceive more discomfort about the ads before the start of the content compared to men, and women in twenties perceived the highest discomfort with intermediate advertisement. Second, respondents who watch more YouTube contents tended to accept more ads to use contents for free. Third, respondents who are willing to use the advertisement blocking service were most aware of the inconvenience of advertisements before starting of YouTube contents. Although users are aware of the inconvenience, the use of advertisement blocking service has not yet been found to be generalized. However, the use of ad blocking service is expected to increase gradually. It would be expected that efforts to regulate advertisement to reduce discomfort about advertisement among users are also required.
