Since elementary school is a time in which basic concepts like attitudes and mindsets about careers are formed, career education is very important to elementary school students. This study was conducted to investigate the effects of a gardening program applying the academic disciplines of Science, Technology, Engineering, Arts, Mathematics, and Society (STEAMS) on developing career education for elementary school students. In order to determine the effectiveness of the program on career development of elementary school students, this study was conducted with 28 upper elementary students in the experimental group who participated in the gardening program, and 30 upper elementary students in the control group who did not. The program was comprised of total 8 sessions, one session per week, with various garden activities. The career development scores of the two groups before and after the program were comparatively analyzed. Before the program, the experimental group had significantly lower scores for career development than the control group. After 8 weeks of the program, the control group did not show any changes in career development, while the experimental group that participated in the program showed a significant increase in career development, resulting in no difference in career development between the two groups after the program. Therefore, the program has positive effects on improving career development of upper elementary students who previously had insufficient career development. Overall, the program had positive effects on career development of upper elementary students, and further research is needed to systematically promote the STEAMS-based gardening program to promote interest and understanding of students by associating plant-based gardening activities with various subjects such as science, art, and social studies.

This research was carried out to investigate seed germination and growth of the perennial plant Apocynum lancifolium under different NaCl concentrations, with a view for future cultivation on reclaimed land. Initial characterization revealed that the average length and weight of A. lancifolium seed pods was 133.6 mm and 0.23 g, respectively, and the thousand-grain weight was 0.59 g. Upon examining the effects of light on seed germination, we found germination to be 1.7% higher under light conditions (90%) than under dark conditions (88.3%). In terms of the response to salt stress, we found that 90% of seeds germinated in the 0.00%, 0.25%, and 0.50% salt treatment groups. Although salt treatment up to a concentration of 0.5% was found to have little effect on seed germination, the rate of germination decreased at higher concentrations and was completely inhibited in the 2% treatment. We also established that germination rates were higher in seeds sown in horticultural topsoil than in the coarse sandy soil found in the plant's natural habitats. Although the growth of A. lancifolium tends to decrease with an increase in salt concentration, we found that the stem thickness, fresh weight, and dry weight of A. lancifolium seedlings subjected to 0.25%-1.0% salt were comparable to those of the control seedling that were not exposed to salt. Furthermore, in contrast to those plants subjected to 2.0% salt, these plants continued to grow and remained viable.

Plants native in Korea have not only ornamental values but also have excellent environmental adaptability, so they can be used as garden plants. Studies on proper volumetric water content (VWC) of substrates have been reported, but many have been conducted in glasshouse conditions where environmental factors were controlled. When considering garden planting, it is necessary to perform the automated irrigation system in outdoor conditions where rainfall occurs at frequent intervals. This research aimed to investigate the VWC suitable for the growth of Minuartia laricina, Arenaria juncea, and Corydalis speciosa in open filed. Sandy soil which consisted of particles of weathered rock was used, and the VWC of 0.15, 0.20, 0.25, and 0.30 ㎥·m^-3 was maintained using an automated irrigation system with capacitance soil moisture sensors and a data logger. No significant differences in growth and antioxidant enzymes activity of A. juncea were observed among VWC treatments. However, the survival rate was low at VWC 0.30 ㎥·m^-3 treatment, which was the highest soil moisture content. Even considering the efficiency of water use, we recommended that VWC 0.15-0.20 ㎥·m^-3 is suitable for the cultivation of A. juncea. Minuartia laricina showed better growth with lower VWC. Because of frequent rainfall in open field, plant volume and survival rate was high even in VWC 0.15 ㎥·m^-3 treatment. In C. speciosa, the plant height, number of shoots and lateral shoots, and fresh and dry weight were higher in plants grown in VWC 0.25 ㎥·m^-3 as compared with that in the plants grown at 0.15, 0.20, and 0.30 ㎥·m^-3. Based on these results, M. laricina needed less water in open filed, and A. juncea and C. speciosa required higher VWC, but excessive water should be avoided.

Mt. Seokseong is located $37^{\circ}15'15'{\sim}37^{\circ}17'00'N$ in latitude at $127^{\circ}09'30'{\sim}127^{\circ}11'00'E$ in longitude in Yongin-si. As the result of cluster analysis, B site has 170 taxa of vascular plants, so it is the most abundant site in this area. And C site has 140 taxa of that, it is secondly abundant. But it has the highest similarity index (53.7%) between A site and B site. To construct natural resort for residents, it needed make thorned park just as hiking course, woods bathing site, aquatic place, pebble path, and natural garden path. And to protect ecological isolation of this area ecobridges must be constructed at Myeokjogogae and at Yongin Medical Hospital.

Vegetation and soil conditions of four sites in west coastal forests in South Korea, were examined to analyze the relationship between Pinus thunbergii forests structure and soil conditions. The P. thunbergii forests were divided into four clusters; 1) P. thunbergii - Prunus sargentii var. sargentii, 2) P. thunbergii - Robinia pseudoacacia, 3) P. thunbergii - P. densiflora and 4) P. thunbergii - Quercus serrata. The soil of each site was poor in chemical characteristics but good enough for land plants to grow because of its low salt concentration. According to the results by CCA Ordination, certain excessive soil nutrition has influenced on vegetation and specific species distribution. Forty eight species were found in the whole sites of coastal forests and some species appeared in every site. They are P. thunbergii, R. pseudoacacia, Rhus chinensis, Idesia polycarpa and Morus alba. For the tree species importance value, P. thunbergii was followed by R. pseudoacacia, Q. serrata, P. densiflora, Celtis sinensis, M. alba, I. polycarpa and Q. mongolica in order.

The natural populations of Lycopus lucidus Turcz. ex Benth. var. hirtus Regel (Lamiaceae) were found in Gangwon province, Korea. This taxon was mainly distinguished from L. lucidus Turcz. ex Benth. var. lucidus by having multicellular hairs on the stem and leaves. However, the delimitation of this taxon from the typical plants of this variety (var. lucidus) was never assessed and the existence of this taxon was obscure in Korea. So, we provide a detailed morphological description of this taxon, as well as its geographical distribution and habitat.

This study gives prospects and tasks for the development of Korean herb industries and suggests as follows; There are some preconditions to be considered for the applications of functional traits of herbs and the effect of the profits when herb garden are promoted in Korea later. To activate Korean herb industries, the development of Korean unique herbs and aromatherapies should be settled down with training of specialists to reconcile the health, the beauty and interiors using herbs with human everyday lift in Korea and the effects of economic benefits should be reconsidered with the activation of processing industries by developing the competitive goods from natural plants outside. To continue the development of Korean herb industries, some businesses should be executed step by step like the expansion of recognition far herbs, the promotion of the bases for the herb industry development and the increase of earnings with using herbs while the industrial-educational cooperation system are built and the settlement of the herb industries should be promoted with systematic devices for those systems preceded.
