Purpose - Focusing on the FGI research method, the current status and issues of barrier-free tourism in Gangwon State were identified, and specific activation plans were derived Design/methodology/approach - This study conducted in-depth interviews with 20 experts related to the tourism industry. The issues, current status, and activation plan of barrier-free tourism in Gangwon State recognized by experts in tourism policy, tourism administration, tourism management, and tourism service industry were derived. Findings - First, the tendency of businesses to be promoted based on the non-disabled by not recognizing the weak as the main tourism demand group, second, confusion caused by the unification of terms related to barrier-free tourism, third, lack of finding tourism constraints subdivided according to the type and degree of disability, fourth, tourism information and evaluation indicators provided by prioritizing the convenience of suppliers rather than consumers, and fifth, the nature of the project focused on improving access to physical infrastructure. Subsequently, the results of the analysis of the plan to revitalize the barrier-free tourism industry in Gangwon State were as follows. First, education and programs to improve disability awareness appropriate to local conditions were activated, second, related information was unified and project sustainability was improved by creating a control tower for the barrier-free tourism industry at the provincial level, third, to overcome the employment crisis based on finding locally tailored jobs related to tourism care professionals, and fourth, to continuously secure quantitative and qualitative data and establish utilization plans. Research implications or Originality - First, it presents theoretical implications for related fields by providing issues and activation measures related to barrier-free tourism from the perspective of experts who are still lacking in research in academia. The practical implications are that based on the opinions of experts working in the tourism field, more specific issues of the barrier-free tourism industry in the province were presented, and policy and practical solutions were presented accordingly, suggesting realistic alternatives that can be carried out in the actual field.

This study investigated the changes in water quality parameters and microbial colonies when ozone was applied to a semi-recirculating aquaculture system (semi-RAS) for the olive flounder Paralichthys olivaceus (500 g in average weight). Concentrations of ozone-produced oxidants (OPO) in rearing tanks were maintained at 0, 0.014, 0.025 mg/L as Cl₂ for 26 days. Except total ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, phosphate phosphorus, chemical oxygen demand, and total suspended solids decreased significantly with increasing OPO concentration in daily and weekly monitoring (P<0.05). Colony forming unit (CFU) counts of heterotrophic marine bacteria decreased in an OPO concentration-dependent manner. Overall reduction rates of microbial colonies in the treatments were 80% higher than those of the control (P<0.05). During the experiment, the OPO concentration-driven ozonation was reliably practiced without any adverse effects on the animals cultured in semi-RAS. Considering the biohazard, operating cost, and stability of ozonation, an OPO concentration of 0.014 mg/L would be sufficient to control water quality parameters and microbial colonies in a semi-RAS.

The purpose of the study is to explore strategies to revitalize the distribution of landscaping plants in Gangwon State (hereinafter referred to as Gangwon-do). To understand the current distribution status and perception of landscape materials in Gangwon-do, a survey was conducted on producers and consumers focusing on cultivation area and method, cultivated species and quantity, purchase species and quantity, and purchase area. Producers often cultivated open land, and in the case of trees and shrubs, most of them cultivated <5 species. On the other hand, consumers preferred field cultivation products when purchasing trees and shrubs. Approximately 6-10 species of trees and shrubs were preferred for a single purchase, confirming an imbalance in the supply and demand of landscaping plants. In addition, both producers and consumers had a positive perception of landscape plant transactions in Gangwon-do; however, the dissatisfaction factors for producers included a small consumer base and difficulties for them in securing standards and quantities. Based on these results, it is necessary to establish a platform that can interconnect producers' landscape plant cultivation information with consumers' requirements to rejuvenate the landscape plant distribution market and enhance competitiveness in Gangwon-do. In addition, this platform is expected to have a positive impact on improving the quality of landscaping plants, setting reasonable prices, and increasing domestic demand in Gangwon-do by providing opportunities for cultivation, promotion, and marketing education through producer support projects.

This study investigated the effects of ozone-produced oxidants (OPO) on the growth, hematology, and histology of olive flounder Paralichthys olivaceus (average weight 500 g), raised in an ozonated semi-recirculating aquaculture system. The system was ozonated to maintained OPO concentrations of 0.004 (Control), 0.014 (OPO15), and 0.025 (OPO25) mg $Cl_2/L$ in culture tanksfor 26 days. The specific growth rate, feed conversion ratio, and survival rate did not significantly differ among the groups (P>0.05), while the daily feeding rate decreased OPO-dose-dependently (P<0.05). OPO appeared to affect the gill, hepatopancreas, and kidney tissues of fish from ozonated tanks. Hematologically, OPO affected some blood indices. The levels of chloride, glucose, glutamic oxaloacetic transaminase, and glutamic pyruvic transaminase were significantly increased in the ozonated groups, while the total cholesterol and cortisol decreased dose-dependently. These results imply that long-term exposure of olive flounder to an OPO concentration ${\geq}0.014mg\;Cl_2/L$ might result in damage to the gill, hepatopancreas, and kidney tissues and cause physiological stress, albeit with no apparent short-term effects on growth or survival.

Alnus japonica is indigenous to korea and usually grows in wet lowlands and damp regions in the mountains. Oregonin, is known as a representative compound of the diarylheptanoid mainly found in Alnus species and has been reported to have anti-inflammatory and antioxidant effects. In this experiment, we conducted a study on the presence of orogonin in the native Alnus japonica from the Baekdudaegan mountain range in Korea. We collected a total of 30 samples from Chuncheon, Yangyang, and Jeongseon and conducted experiments. In the HPLC analysis, we confirmed that oregonin was detected in all samples. After the quantitative analysis, samples with the highest content from each region were selected and LC-MS/MS experiments were performed. As a result, the same molecular weight as oregonin, 477.2 m/z, was confirmed in all samples.

An analytical method was developed for the determination of phenol (P) and the seven substituted phenols in water samples and fish tissue samples collected from three streams located in eastern Gangwon State in spring and summer. The phenols were extracted and then derivatized to phenyl acetates using acetic anhydride. The derivatives were subsequently identified and quantified using gas chromatography coupled with mass spectrometry. P and 4-nitrophenol (4NP) were found at relatively high levels in water, ranging from below the method detection limit (MDL) to 3.32 ㎍/L and from < MDL to 4.91 ㎍/L, respectively. P and 4NP were also the dominant compounds in the fish tissue, ranging from < MDL to 407 ㎍/kg and from < MDL to 870 ㎍/kg, respectively. Phenol concentrations were significantly higher in spring than in summer. The ecological risk quotient calculated for P was higher than 4NP but not high enough to pose any risk of adverse effects to fish health.

This study investigated the effects of photoperiod (NL 12L:12D and LL 24L:0D) and body sizes (30 g and 50 g) on parr-smolt transformation, post-smolt growth and blood properties in the off-season parr-smolt stage of Atlantic salmon reared in a recirculating aquaculture system (RAS). Potential off-season salmon smolt were reared in a freshwater RAS for 80 days and then all experimental fish were transferred to seawater. In both LL groups (LL-30 and LL-50), we recorded and increase in specific growth rate and reduction in feed conversion, although there were no significant difference in body size. The values of osmolality, and serum Na⁺, Cl^- and cortisol concentrations in the LL groups were maintained at lower levels than in NL group fish, and LL group fish were observed to recover to the pre-seawater adaptation state more rapidly than those in the NL group. ID chips were inserted in all smolts reared in freshwater. These fish were subsequently transferred to full-strength seawater and thereafter individual growth rates were monitored for 120 days. The results indicated that compared with smolt reared under natural photoperiodic condition, 24 h lighting in freshwater contributed to enhancing post-smolt specific growth rate in seawater.

Previously, we reported the concept of a cloud-based telemedicine platform for patients with intracerebral hemorrhage (ICH) at local emergency rooms in rural and medically underserved areas in Gangwon state by combining artificial intelligence and remote consultation with a neurosurgeon. Developing a telemedicine ICH treatment protocol exclusively for doctors with less ICH expertise working in emergency rooms should be part of establishing this system. Difficulties arise in providing appropriate early treatment for ICH in rural and underserved areas before the patient is transferred to a nearby hub hospital with stroke specialists. This has been an unmet medical need for decades. The available reporting ICH guidelines are realistically applicable in university hospitals with a well-equipped infrastructure. However, it is very difficult for doctors inexperienced with ICH treatment to appropriately select and deliver ICH treatment based on the guidelines. To address these issues, we developed an ICH telemedicine protocol. Neurosurgeons from four university hospitals in Gangwon state first wrote the guidelines, and professors with extensive ICH expertise across the country revised them. Guidelines and recommendations for ICH management were described as simply as possible to allow more doctors to use them easily. We hope that our effort in developing the telemedicine protocols will ultimately improve the quality of ICH treatment in local emergency rooms in rural and underserved areas in Gangwon state.
