The growth performance of Eastern white pine (Pinus storbus L.) was studied with six provenances in four plantations. All growth performances were significantly different among provenances and plantations. The most outstanding source in volume growth at age 39 is North Carolina in all plantations and this trends had been started from four years old seedlings. In plantations, the growth is best in ChunCheon plantation while that is worst in GunPo plantation. The Effect of plantations was thought to be larger than that of provenances growth of P. strobus. A pattern of growth by ages was different by among plantations and even ate age about 40, the growth was still vigorous. Annual precipitation, foggy days, altitude and sand contents in soil are positively correlated with growth and the correlations between by ages were very high.

In the 1960s, both South and North Korea needed to stabilize their regimes, and propaganda films were at the core of establishing this purpose. South Korea claimed legitimacy of a military government and called for service to fulfill the government's mission of the era, while North Korea emphasized the impeccability of their leader and the superiority of their socialist system. This study investigates image reproduction strategies used in South and North Korean propaganda films at the time under the context of domestic and foreign environments in the 1960s. First, South and North Korea portrayed their rulers as a strong leader and friendly leader, respectively, to establish legitimacy. Second, South and North Korea tried to image the same incident from different views in order to instill the spirit of age defined from their own perspectives. Third, propaganda films at the time portrayed desirable images of citizens (people) and visualized a flawless government. Authoritarian governments in South and North Korea in the 1960s facilitated the establishment of the so-called official society through propaganda films.

정부에서는 공적연금 운용 업무를 수행하는 연금공단에 대해서 지방세특례제한법상 조세감면 혜택을 부여해 왔으나, 2014년도부터는 지방자치단체의 재정확충을 위해서 지방세 특례를 폐지하였다. 이러한 지방세 특례 폐지가 연금재정에 부정적인 영향을 미치게 됨에 따라, 본 연구에서는 현행 사학연금공단에 대한 지방세 감면 폐지의 문제점를 살펴보고, 이를 통해 법 개정 등의 개선방안을 모색하고자 하였다. 구체적으로 2014년 말에 시행된 지방세 감면 규정의 일괄적인 폐지는 2002년에 개정된 연금소득 과세원칙에 비추어볼 때 과세원칙 위배와 함께 미적립 연금충당부채를 지니고 있는 연금공단의 제도적인 특성을 감안하지 않는 문제점이 있어 이를 검토하고 이에 대한 개선방안을 다음과 같이 제시하고자 한다. 본 연구에서 제시하는 개선방안은 다음과 같다. 첫째, 과거와 같이 사학연금공단에 대한 지방세특례를 부활하여 연금재정의 안정화를 제고할 필요가 있다. 둘째, 연금소득 원칙상 갹출 시 공제, 운용 시 비과세 및 연금 수령 시 과세를 하도록 하고 있으므로 현행 연기금을 운용하고 있는 사학연금공단에 대하여 운용단계에서 지방세를 부과하는 것은 연금소득 과세 원칙상 재검토가 필요하다. 셋째, 현재 연금기금의 운용이익에 대해서는 법인세가 비과세되으나 지방세는 과세가 되고 있어 국세와 지방세의 형평성 측면에서 문제가 있으므로 원칙적인 검토가 필요하다. 넷째, 미적립 연금충당부채를 지니고 있는 연금공단의 성격을 고려하여 현행 지방세의 부과는 연금공단의 기관 특성을 고려하지 않은 것으로 보여진다. 마지막으로, 가장 공적인 업무를 수행하고 있는 기관임에도 불구하고 타 비영리법인에서는 아직도 지방세특례가 존재하고 있는 실정이다. 따라서 사학연금공단은 공적인 업무를 수행하는 기관임에도 불구하고 지방세 특례가 폐지되었으므로 이에 대한 지원이 필요하다. 본 연구는 사학연금공단의 연금재정 안정화와 함께 과세원칙에 부합하도록 운용단계에서 반드시 필요한 연금관리 조직의 지방세 특례 부여 방안을 모색함으로써 사학연금공단의 지방세 지원의 타당성과 개선방안을 제시했다는 점에서 연구의 의의가 있다.

The purpose of this research is to suggest economic feasibility of cultivating Acer Mono by using profitability analysis to forest owners. To achieve this research objective, forest owner household survey with intensive cultivating has been conducted about a sap production on its age of tree. And input costs and sap production costs are calculated with silvicultural system from plant to regeneration cutting. Total income is the sum of its sap sales and thinning and regeneration cutting. The method of profitability analysis was used on the NPV(Net Present Value) and IRR(internal rate of return). Finally, when 3% discount rate is applied, NPV is about 59,436 thousand won and IRR value is 9.22% at this point. This result, therefore, proves that cultivating Acer Mono is economical feasibility to forest owners.

Water distribution systems (WDSs) are a representative infrastructure injecting chlorine to disinfect the pathogenic microorganisms and supplying water from sources to consumers. Also, WDSs prescribe to maintain the usual standard (0.1-4.0 mg/L) of residual chlorine. However, the user's usage pattern, water age, network shape, and type affect the hydraulic features (i.e. nodal pressure, pipe velocity) and water quality features (i.e., the residual chlorine concentration). Therefore, this study developed an optimization approach for optimizing WDSs considering water quality-hydraulic factors using Multi-objective Harmony Search (MOHS). The design cost and the system resilience were applied as the design objective functions, and the nodal pressure and the concentration of residual chlorine are used as constraints. The derived optimal designs through this approach were analyzed according to network characteristics such as the network shapes and type. These optimal designs can meet the safety of economic and water quality aspects to increase user acceptance.

As the 3D modeling technology and conversational algorithm is developed, digital humans are being used in various fields, and also virtual bankers have begun to appear in banks, including major banks such as Shin-Han Bank and Nong-Hyup Bank. However, most of the research of digital human mainly focus on its appearance, and research on robot persona that should be considered in anthropomorphizing a robot is insufficient. In this study, an experiment was conducted to find out the user experience of three scenarios (student ID receipt, deposit and withdrawal account opening, leasehold loan consultation) in which the level of anthropomorphism of the speech strategy and the level of personal information use differed in the specific context of banking. As a result of the study, social presence and usefulness had an interactive effect on the scenario and the level of anthropomorphism. There was no interaction effect on intimacy, trustworthiness, and perceived intelligence, but a tendency could be confirmed.

The operation method of offline venues such as local festivals usually has problems such as the absence of real-time events and booth information, wasting time in the process of purchasing and receiving goods, and stagnating the movement of guests. This study increases the convenience of guests and managers by integrating all contents in the venue in the form of booth, thereby increasing the uniformity of event information and the efficiency of booth operation. In addition, a system was designed to minimize movement problems and improve performance by detecting the movement of guests within the venue and increasing the efficiency of arranging booths based on location data. It has been developed as a low-cost system that measures wireless packets with portable wireless LAN APs and control units. This has advantages in the operation of the venue, which consists of the installation and dismantling of variable booths in a short period of time. It is expected that the integrated operation of the venue will be utilized by linking the movement data of guests to activate visits and increase sales through data-based promotions.

This study attempted to propose a faceted search function to supplement metadata for existing presidential gifts. To this end, based on 3,574 presidential gifts provided online by the Presidential Archives, identified the characteristics of records extracted from the gift name, gift giver, gift country, gift date, and receipt process, specifications, and characteristics of the presidential gift. Based on this, study designed a facet-based classification of presidential gifts with 5 basic facets and 51 sub-facets and structured facets define each facet element and assign an arrangement order and symbol. This classification system can be expected to be utilized as a basis for building faceted navigation by applying it to a search system. Through the study, it was confirmed that it was necessary to develop a new classification system for presidential gifts, and it was proposed to apply facet classification as an alternative classification system for this purpose.
