Traditional cultural resources in the region have unique cultural characteristics and are highly likely to be differentiated content resources. Therefore, when local cultural resources are developed as content, they can be given a role as a brand symbolizing the region together with economic value creation. In this paper, we propose a method to utilize traditional cultural resources in Jeonnam region as content material and to strengthen the connection with 'Namdo Renaissance' project contents in Jeonnam province. We propose seven regions as a region with content relevance for inter-regional collaboration through resource elements and analysis of Jeonnam cities and counties. We suggest "Story SarangBang" so that we can uncover and systematize stories with symbolic character by region. The developed story resources are developed as experiential contents through realistic media production technology and virtual reality platform and expanded to tourism contents and expanded to the window effect of contents. Also, by expanding cooperation governance between regions, it is possible to enhance opportunities for development of joint contents and enhance utilization as tourist contents, thereby contributing to regional economic development and related industries development.

This study was conducted to provide a rational forest management method for a natural oak (Quercus variavilis) forest stand in the central part of South Korea based on characteristics of growth and water relation parameters. Average volume per hectare was 175.1 ㎥ in the study site of oak stands. Basal area and volume of each direction appeared to increase as the slope direction moves from north to south, but annual mean increment and periodic annual increment of DBH for 10 years showed the lowest value at the southern aspect. Maximum water potentials measured between 12 and 14 o'clock were analyzed by direction and elevation in the oak stands. Water potential of oak decreased as the slope changed from the north to the south aspect and water potential increased at lower elevations. Soil water content for the oak stands tended to decrease as the aspect shifted from north to south. Water potential and soil moisture content were highly correlated. It appears that oaks have a higher moisture requirement at the southern aspect, because of stand density related to intraspecific competition.

Seasonal succession of algae and water quality parameters were studied in artificial reservoirs in Daegu city from 2000 to 2001. The algal succession was evaluated with respect to dom-inant class and their frequencies. Succession order of algae in two reservoirs was : Bacillariophyceae longrightarrow Chlo-rophyceae longrightarrow Cyanobacteria longrightarrow Bacillariophyceae longrightarrow Bacillariophyceae longrightarrow Cyanobacteria longrightarrow Cyanobacteria longrightarrow Cyanobacteria. This succession order was different from other studies. The local environment condition maybe affects the succession of algae in these reservoirs. As result of correlation analysis between algal biom-ass and water quality parameters, we got low correlation coefficients. Also we got low correlation coefficients between chlorophyll-a and algal biomass. Between chlorophyll-a and water quality parameters, we got high correlation coefficients. An approach having attention to cell biovolume rather than cell number is made to understand the algal community and the ecosystem of reservoir.

The objective of this study was to isolate algae growth inhibiting microorganism to biologically control Microcystis aeruginosa, which is a harmful cyanobacterium. Various bacterial strains were isolated in this study, and four bacterial strains of M1~M4 exhibited remarkable growth inhibiting activity against M. aeruginosa. Based on the 16S rRNA analysis, the isolated M1~M4 strains were identified, and isolated four strains were rod-type and gram-negative. In particular, as well as respective single strain, co-culture of the isolated M1~M4 strains showed obvious algicidal activity against M. aeruginosa. When mixed four strains were inoculated, about 50% of the chlorophyll a was reduced after two days, about 70% after four days, and about 80% after seven days. From these results mentioned above, the four bacterial strains may contribute to the control of harmful M. aeruginosa.

Social psychological suspense has been increased rapidly because of a lack of morality by individual personality and offense by dissatisfactory desire. To help safety area from the situation, a professional private security guard company is increased remarkably. Followed by data from the National Statistical Office, the security guard companies and the guards had been increased. In 1999, there were 994companies and 25,464 employees were registered but in 2004, there were 1,081companies and 35,876 employees were registered. Based on the data, Security guard becomes a popular career but we should consider that the service also has been improved. Dissatisfactory service could occur to a fastidious person. The purpose of this study is to become a trustful and respectful private guard's activity through analyze defective activities of private guards and matters of what the customer feels.

Since some cyanobacterial isolates under selective culturing conditions are lacking of characteristic specialized cells or showing altered morphology, the morpho-taxonomic criteria are not accurate enough to discriminate between species. Instead of morphological parameters, a method based on the single or the combination of repetitive oligonucleotides in a single PCR, repetitive oligonucleotides-primed PCR (ROP-PCR), was applied to generate DNA profiles for members of the cyanobacterial genera Anabaena and Oscillatoria, both of which are responsible for causing poisonous blooms in various freshwater systems. ROP-PCR performed on 10 isolates of the cyanobacteria with ERIC and REP sequences from gram-negative bacteria, STRR1A and LTRR sequences derived from cyanobacterial genome, and eukaryotic repetitive sequences, led to the identification of distinct genotypes, and provided specific and repeatable DNA fingerprints for cyanobacterial isolates. Grouping analysis of cyanobacterial isolates showed a signifiant difference depending on the primer used in PCR.

This study was conducted to provide a national forest management method for natural Pinus densiflora forest stands in central South Korea based on growth characteristics and water relations. Average stand volume per hectare was 259.3㎥ in the pine study site. Basal area, volume, annual mean increment and periodic annual increment of DBH for 10 years at each slope aspect appeared to decrease as the aspect shifts from north to south. Stems per hectare showed the lowest value at the northern aspect. Maximum water potentials measured between 12 and 14 o'clock were analyzed by aspect and elevation. Water potential of pine decreased as the aspect changed from north to south, and water potential increased at lower elevations. Soil water content for the pine stands tended to decrease as the aspect shifted from north to south. Water potential and soil moisture content were highly correlated. Soil water deficits indicate that pines have a higher moisture requirement on the ridge and the southern aspect.

The intraocular pressure for Korean youth were measured by using tonometer (AT555-Reichert). The relative frequency distributions of intraocular pressures have been studied for samples of 1,027 persons(475 males, 552 females). The most commonly recorded IOP for both men and women was around 14.5mmHg and 17.5mmHg, respectively. They were in the range of 7 to 23mmHg(males) and 7 to 22mmHg(females). The median pressure(cumulative frequency=0.5%) is 13.0~16.5mmHg for males and 16.5~18.5mmHg for females, so the values for females are slightly higher than males. The mean pressure is 15.2mmHg for males and 15.8mmHg for females, respectively. The 98% of population was in the range of the normal IOP. There are long-term diurnal variation in mean intraocular pressure and the IOP was decreased as a function of time from morning to night. The measured IOP was affected by several factors: exercise made to decrease the IOP and tight collars, dark places and posture of decubitus position got to elevate the IOP.

2000년 이후 중국 해군은 빠르게 성장하고 있고 이러한 해군의 성장과 더불어 중국은 남중국해 내 도서를 군사기지화 하고 대함 미사일을 개발하고 있다. 이는 제1도련선 내 중국의 해양통제를 위한 노력으로써 인도-태평양 지역 내 미 해군 전력 및 기지에 심각한 위협으로 작용하여 미국의 해양 지배력을 약화시키는데 기여하고 있다. 이를 극복하기 위해서 미국은 인도-태평양 지역내 동맹국과 파트너국들과 함께 시간, 공간, 전력(화력, 군수) 측면에서 작전개념을 발전시켜야 한다. 우선 시간적인 측면에서 중국의 위협에 신속하게 대응하기 위해서 인도-태평양 지역내 국가들의 공중전력(UAVs)과 해상전력(Aegis ships)을 활용하여 대중 정보공유 체계를 강화시켜야 한다. 다음으로 공간적인 측면에서 중국의 위협으로터 인도-태평양 지역 내 미해군의 전력 및 기지를 보호하기 위해서 미 해군 전력을 일본과 호주로 분산 배치시키고 동맹국과 파트너국들의 이지스함, 잠수함 및 무인 수중전력을 적극 활용해야 한다. 전력 측면에서는 해상 기반 화력과 지상 기반 화력을 통합하여 화력의 치명성을 강화해야 하고 인도와의 협력 및 인도-태평양 지역내 함정 손상통제 시설의 확충을 통해서 해상 군수지원 능력을 발전시켜야 한다. 이러한 미 해군의 작전개념 발전 방향이 주는 한국 해군에의 함의는 다음과 같다. 첫째, 미·중간 남중국해 분쟁 발생시 중국의 미사일 위협으로부터 한국 내 위치하고 있는 한·미 해군 전력 보호를 위해 미사일 방어체계(이지스함, 사드 등)를 발전시켜야 한다. 둘째, 대중 감시·정찰 및 미 항공모함단 방호 전력으로 활용 가능한 한국형 원자력 잠수함을 개발해야 한다. 셋째, 미국 뿐만 아니라 인도-태평양 지역내 파트너 국가들을 포함하는 연합훈련을 확대·발전시킴으로써 남중국해내 중국의 해양통제 노력에 대응해야 한다. 넷째, 인명손실을 최소화하고 효율적으로 해군력을 현시할 수 있는 무인 수중·수상체계를 지속적으로 발전시켜 나가야 한다.
