Carbon nanotubes (CNTs) stand at the frontier of nanotechnology and are destined to stimulate the next industrial revolution. Rapid increase in their production and use in the technology industry have led to concerns over the effects of CNT on human health and the environment. The prominent use of CNTs in biomedical applications also increases the possibility of human exposure, while properties such as their high aspect ratio (fiber-like shape) and large surface area raise safety concerns for human health if exposure does occur. It is crucial to develop viable alternatives to in vivo tests in order to evaluate the toxicity of engineered CNTs and develop validated experimental models capable of identifying CNTs' toxic effects and predicting their level of toxicity in the human respiratory system. Human lung epithelial cells serve as a barrier at the interface between the surrounding air and lung tissues in response to exogenous particles such as air-pollutants, including CNTs. Monolayer culture of the key individual cell types has provided abundant fundamental information on the response of these cells to external perturbations. However, such systems are limited by the absence of cell-cell interactions and their dynamic nature, which are both present in vivo. In this review, we suggested two viable alternatives to in vivo tests to evaluate the health risk of human exposure to CNTs.

As human brands, Idols, the central members of K-pop, are actively engaging in various industries based on the support of their fandoms, greatly impacting the national economy. In particular, due to the development of digital devices and technologies, they are active both online and offline, and idol avatars are a significant part of their activities across diverse contexts. Therefore, this study aims to categorize avatars used in various contexts and explore fandoms' perceptions according to each type. Based on case studies and literature review, idol avatar usage was categorized into products, supplier-led content, and interactive content, and accordingly, surveys and in-depth interviews were conducted. As a result, regardless of category, fandom showed a negative perception of idol avatar usage, as shown in the order of interactive content, supplier-led content, and products. Regarding human brand characteristics of idol avatars, attractiveness was evaluated higher than intimacy and likeability. However, the attachment to real-life idols showed a higher correlation with the characteristics of intimacy and likeability than attractiveness. This study is significant as it looked at the future directions of idol avatar usage by analyzing the fandoms' perception of avatar usage in the K-pop industry from a human brand perspective.

It is not sufficient to control the indoor thermal environment using only one or two parameters by itself as human response for the control of indoor thermal environment. So a proper environmental thermal index is required for the control of indoor thermal environment effectively. In this study, the physical environment was measured and analysed and the skin temperature of the subjects and their response were investigated to evaluate the optimum thermal comfort range for cooling season in an apartment house. As a result, the optimal temperature was 26.1$^{\circ}C$ and the temperature ranges which more than 80% responded as satisfactory were 24.1~28.$0^{\circ}C$, respectively. As the OT had most significant interrelation with the PMV, it is desirable to use the OT in evaluating the thermal environment during cooling. Also, the comfort range was concluded between OT 25.5~27.3$^{\circ}C$ by appointing the PMV of -0.5~0.5 as the optimum comfort condition. In addition, the Human responses were compared with calculated PMV, OT and MRT and the relationships are suggested in order to utilize to control indoor thermal environment.

This paper reviewed the concept of the environ ment in Korean traditional thought according to Shamamism, Buddhism, Confucianism, and Taoism. The differences in the views of the environment between Korean traditional thought and Western thought were compared according to the ontological point of view. This study attempted to investigate the concept of environment, one of the four metaparadigm(human, environment, health, nursing)as it is experssed in Korean traditional thought. However, it was difficult to find the concept of environment separated out in the traditional thought pattern. Instead, environment concepts are represented in the natural views and universal views. Even though the four traditional thought patterns (Shamaism, Buddhism, Confucianism and Taoism) represent some difference in their view of nature, the combination of natural and human harmony, anti-dichotomy and so forth are emphasized in common in four thought patterns. Korean traditional thought includes a more comprehensive meaning than the unitary-transformative perspective discussed in modern Westen thought patterns. Environment has been dealt with in narrow view until now. Now we avoid this narrow view and must regard environment as an integrated concept with person. Through this research, it is hoped that a contribution will be made to the development of nursing knowledge suitable to Korean culture.

${\delta}$-Aminolevulinic acid (ALA) is an endogenous metabolite formed in the mitochondria from succinyl-CoA and glycine, and plays a key role in the living body as an intermediate of the compound in the porphyrin biosynthesis pathway. ALA has been commonly used in photodynamic therapy for several years, because ALA is of interest as a biodegradable mediator, a growth regulator, and an effective agent used in dermatology. Here, we determined which ALA derivatives were the most effective for the inhibition of the cell proliferation and growth of human fibroblast. As a result, we found that the treatment of ALA derivatives including ALA, ALAP (ALA phosphate salt), MAL (Methyl 5-aminolevulinate hydrochloride salt), PBGL (phophobilinogen lactam) and PBGH (phophobilinogen-HCl) could attenuate cell proliferation of human fibroblast cells. Among them, PBGH was the most effective derivative. In addition, PBGH treatment could induce mitochondrial membrane depolarization, leading to cell death of human fibroblast. These results suggest that mitochondrial membrane depolarization induced by ALA and PBGH treatment might be responsible for inhibition of cell proliferation and death. Taken together, our results propose the possibility that PBGH can be used as one of the effective drugs in human skin disease, psoriasis.
