This paper is aimed to study the late Neolithic Age in North Korea in order to closely examine a transition process into the Bronze Age in the Korean peninsula. Thus, the pottery with lightning design was selected as target data. Since the pottery with lightning design is fundamental data that North Korea's archeologists have used for chronological recordings of the late Neolithic Age in the northwest region, the parallel relationship between the eastern and the western region was established with comparison of pottery with lightning design in the northeastern region. The examination focuses on data that cover the target region of the pottery with lightning design of the adjacent Southern Primorskii region including the counterpart of the northwestern and the northeastern region. As a result, some attribute analyses revealed that the pottery with lightning design was affected by the counterpart of the northwestern region near the Yalu River. Prior to genealogical and chronological recordings of the pottery with lightning design in the northeastern region, the pottery with lightning design in the northwestern region was recorded chronologically in order to examine its specific development process. Consequently, in the second period of the Neolithic Age, the pottery with lightning design in the northwestern region was assumed to have an impact on the counterpart in the northeastern region. The classification of the pottery with lightning design in the northeastern region shall be based on 4-period development. According to this classification, the pottery, which was found in the Tumen river basin, was thought to belong to the first period. The pottery went through genealogy differentiation in the second period and when entering into the third period, the pottery spread to inland of south Primorskii. The pottery was assumed to exist in the southern Primorskii region until the tip end (the fourth period) of the Neolithic Age. It is assumed that considering the fact that climate change led to the agriculture movement, Zaisanovka culture, i.e. the late Ne Neolithic Age, moved to the southern Primorskii region along the Tumen River basin.

With the development of media, modern times are actively exchanging cultures and information around the world. Therefore, product development using traditional material, which are Korean cultural heritages, can be said to be another medium that can promote our unique culture to the world. Therefore, this study attempted to develop a product suitable for the modern lifestyle that combines tradition and modernity by investigating and analyzing Korean roof tiles and applying the formative elements identified as a result of the study. Among the types of roof tiles, a Sumaksai, which is located on the front of the roof and stands out for decoration, was selected as the subject of the study, and it was developed by combining it with lighting and plates as an item for modern people seeking a life full of personality. In product development, we tried to express the traditional style as it is by making the most of the elements of the Sumaksai, and the lotus pattern, which was most commonly used in each era when roof tiles were made, was simplified and applied to the product. As the products developed in this way are used in our daily lives, we hope that users' interest in ours will increase, and that the development of various products through research on traditional material can be activated as a way to spread our culture around the world.

As paprika plants grew in a glass greenhouse from November 2022 to March 2023, the amount of light at each plant height, leaf temperature, transpiration rate, and water vapor pressure were measured. Accumulated leaf temperature was higher at the top of the plant than at the bottom. Over time, the leaf temperature measured around 11-13 AM changed from 26.55→23.21→22.80→26.67℃ in the lower part (pL), and from 26.52→24.48→24.55→27.78℃ in the upper part (pAs). And VPD changed from 1.45→0.94→0.74→1.46kPa in pL and from 1.11→0.86→0.71→1.28kPa in pAs. Accordingly, the transpiration rate changed from 4.25→0.17→4.08→0.52mmol·m^-2·s^-1 in pL, 7.61→2.45→1.94→4.39→0.52mmol·m^-2·s^-1 in pAs, and from pAs to pL. It was significantly higher than The difference between the lower and upper parts (pL-pAs) was higher in pAs than pL in leaf temperature, light intensity, and transpiration rate, but the water vapor pressure difference was higher in pL. In this way, paprika shows differences in the environment and photosynthetic factors between the upper and lower parts during the cultivation period, so it is judged that this needs to be taken into consideration in future research.

Task of circling the pagoda of Waljeongsa(Woljeongsa Tabdori) is the major intangible cultural heritage with representativeness and historical meaning as a Buddhism culture, one of the Buddhism folk plays, which was firstly played after the liberation. Woljeongsa Tabdori holds significant designation importance in terms of Buddhism folklore heritage with Korean unique tradition and identity of Gangwon-do province. Temples are demonstrating Tabdori nationwide but Woljeongsa Tabdori is the unique case that systematically inherits the culture based on the designation of being intangible cultural heritage. That is why it is needed to focus on the cultural and internal value of Woljeongsa Tabdori. Tabdori is the integrated symbol of Buddhism respect and worship to the Buddha and pagoda. It is hard to presume the originality of Woljeongsa Tabdori: given the history of Woljeonsa temple, it lies into Goguryeo traditional play and Bokhui(Pagoda circling folk play) in Silla era. It fits into the courtesy of Circumambulating Stupa considering Moon in Goguryo mural, background of Odaesan Hwaeom thought/tripitaka and essence of Octagonal 9-story stone pagoda. At the first stage of Tabdori, Buddhist musical instruments such as Buddhism temple bell, singing bowl, cloud-shaped gong and wooden-fish. However, later, Samhyeon Yukgak has been added and then, Boyeom and Bakpaljeongjinga were singing: it could be interpreted that it was a pure Buddhist ceremony but it has become to have traditional aspect and been spread to the public. The origin of Woljeongsa Tabdori is related to the explanation of Circumambulating Stupa that experiences the glory of the ending ceremony. When a temple has a rite, the Buddhists make an offering to the Buddha. At that time, Buddhist prayer, sermon and chant are followed. After the rite, the Buddhists are circling the pagoda with the monks while praying for Buddhist charity and making their own wishes. It prays not only going after death to Nirvana of the one but also national prosperity and the welfare of the people for peaceful reign. As the temple holds bigger rites, many Buddhists gather and the Tabdori was a success. The scene of circling the pagoda and making own wishes in line with the Buddhist sermon was solemn. The idea on changes and convergence of Woljeongsa Tabdori requires strategic inheritance to promote the transmission while maintaining the paragon and purpose of designating the cultural heritage and reviving its identity. Korean Tabdori was held in Buddha's birthday in April and the mid-autumn day. Tabdori is a memorial service type Buddhist ceremony that once the monk holds the Buddhist rosary, circles the pagoda and sings the great mind and charity of the Buddha, Buddhists follow the step, lighting the lantern, circling the pagoda and praying for the gentle and easy death. Transmission education of the successor, diversified approach of the expert's advice and discourse on the revival of the origin should be reinforced in phases.

The goal of this research was to develop the effectiveness of in vitro culture method for A. formosanus and study the environment in vitro conditions affecting on growth. The first series of experiments were examined to investigate the response of three different basal media, MS (Murashige and Skoog, 1962), Knudson (KC; Knudson, 1946) and modified hyponex on growth and multiplication during in vitro culture. Multiple shoot proliferation was induced in shoot tip explants on Hyponex (H3) media supplemented with BA (1 mg1$\^$-1/) or TDZ (1-2 mg1$\^$-1/). Addition of activated charcoal (1%) to the TDZ containing medium promoted rapid shoot tip proliferation (11.1 shoots per explant) but the same medium had an opposite effect resulting in poor proliferation in the nodal explants. However, the regenerated shoots had slow growth rate and failed to elongate. This problem was overcome by transferring the shoot clumps to a hormone free H3 media supplemented with 2% sucrose and 0.5% activated charcoal. Using bioreactor culture for scaling up was also shown the best way for multiple shoot induction and growth of this plant. The second series of experiments was studied to investigate the effect of physical environment factors on growth of in vitro plantlets. The Anoectochilus formosanus plantlets were cultured under different air exchange rate (0.1, 0.9, 1.2h$\^$-1/), without sucrose or supplement 20g.1$\^$-1/ (photoautotrophic or photomixotrophic, respectively), and different photosynthesis photon flux (40, 80, 120 ,${\mu}$mol.m$^2$.s$\^$-1/- PPF). Under non-enrichment CO$_2$ treatment, slow growth was observed in photoautotrophical condition as compared with photomixotrophical condition on shoot height, fresh weigh and dry weight parameters; High air exchange (1.2.h-l) was found to be inadequate for plant growth in photomixotrophical condition. On the contrary, under CO$_2$, enrichment treatment, the plant growth parameters were sharply (visibly) improved on photoautotrophic treatments, especially on the treatment with air exchange rate of 0.9.h-1. The growth of plant in photoautotrophic condition was not inferior compared with photomixotrophic, and the best growth of plantlet was observed in treatment with low air exchange rate (0.9.h-1). Raising the PPF level from 80 to 120${\mu}$mol.m$\^$-2/.s$\^$-1/ decreased the plant height, particularly at 120${\mu}$mol.m$\^$-2/.s$\^$-1/ in photoautotrophic condition, fresh weight and dry weight declined noticeably. At the PPF of 120${\mu}$mol.m$\^$-2/,s$\^$-1/, chlorophyll contents lowed compared to those grown under low PPF but time courses of net photosynthesis rate was decreased noticeably. Light quality mainly affected morphological variables, changes of light quality also positively affected biomass production via changes in leaf area, stem elongation, chlorophyll content. Plant biomass was reduced when A. formosanus were grown under red LEDs in the absence of blue wavelengths compare to plants grown under supplemental blue light or under fluorescent light. Stem elongation was observed under red and blue light in the present experiment. Smaller leaf area has found under blue light than with other lighting treatments. Chlorophyll degradation was more pronounced in red and blue light compared with white light or red plus blue light which consequent affected the photosynthetic capacity of the plant. The third series of experiment were studied to investigate the effect of physical environment factors on growth of ex vitro plants including photosynthesis photon flux (PPF), light quality, growing substrates, electrical conductivity (EC) and humidity conditions. In the present experiments, response of plant on PPF and light quality was similar in vitro plants under photosynthesis photon flux 40${\mu}$mol.m,$\^$-2/.s$\^$-1/ and white light or blue plus red lights were the best growth. Substrates testing results were indicated cocopeat or peat moss were good substrates for A. formosanus growth under the greenhouse conditions. In case of A. formosanus plants, EC is generally maintained in the range 0.7 to 1.5 dS.m-1 was shown best results in growth of this plant. Keeping high humidity over 70% under low radiation enhanced growth rate and mass production.

Along with hardware implementation of cultural arts, the importance of cultivating and securing professionals who are able to operate and mange it from the political perspective is highlighted as a political issue. In addition, with growing public demand for culture, performing arts are enlarged and professionalized, and this increased the number of large-scale musicals and activated exchanges with overseas performances, which raised the demand for personnel of performing technology. Like this, growing theaters require professionals in the performing technology field for technically safe and quality performance. The certification system for performing arts professionals is to develop quality of theaters and performing arts by increasing vocational professionalism and safety in the performing technology field. This system performed since 2000 is getting positioned, and employees who worked for the performing technology field at this time showed a lot of attentions with certainty they would receive credit for artistic professionalism and raise pride as a performing arts professional. However, the government's political strategy to secure professionals of cultural arts and interest in human resource(HR) policy in the performing arts field were relatively insufficient. Therefore, this study examined the problems by looking into actual conditions regarding operation and role under the initial purpose of the certification system, and purposed the improvement plan as a first certification system to cultivate Korean performing arts professionals.
