PURPOSES : The effect of yellow carpet visibility enhancement was verified and its impact on traffic safety for effective introduction of traffic safety facilities was studied. METHODS : There is currently no scientific evidence demonstrating that yellow carpets improve pedestrian awareness. In this study, the effect of increasing visibility caused by the installation of yellow carpet was verified, and the effect of improving the level of traffic safety was examined through an objective analysis. A drone was used to collect and analyze video data to compare the driving speeds of vehicles passing near yellow carpets at six different sites and diagnose the effects of speed reduction. RESULTS : The results showed that the visibility improvement values before and after the installation of the yellow carpet differed from place to place, but a visibility improvement effect existed in certain cases. In terms of the adequacy of the installation site, the yellow carpet had no deceleration effect on vehicles driving on signalized local streets and collector highways. It was found that there was a speed reduction effect on unsignalized local streets. CONCLUSIONS : To enhance traffic safety promotion, yellow carpets should be placed on unsignalized local streets. It is important to place the yellow carpet in the right place in a proper manner.

PURPOSES : High temperatures induce excessive expansion in pavements, thus causing the closure of contraction joints between expansion joints. This results in the integration of slabs within the expansion joints into a unified slab. Compressive forces are generated owing to the friction that ensues between the unified slab and lower base layer. As the integrated slab expands and exceeds the allowable width of the expansion joint, the end restraint generates an additional compressive force. The escalating force, which reaches a critical threshold, induces buckling, thus compromising stability and causing blow-up incidents, which poses a significant hazard to road users. The unpredictable nature of blow-up incidents render their accurate prediction challenging because the compressive force within the slab must be predicted and the threshold for blow-up occurrence must be determined. METHODS : In this study, a GWNU blow-up model was developed to predict both the compressive force and period of blow-up incidents in jointed concrete pavements. The climate conditions, pavement structure, materials, and expansion joints were considered in this model. In the first stage of the model, the time at which the integrated slab expanded and surpassed the allowable width of the expansion joint was determined, and the compressive force was calculated. Subsequently, the compressive force within the integrated slab, considering both the end restraints and friction, was predicted. A large-scale blow-up test was performed to measure the blow-up force based on changes in the geometric imperfections. The measured blow-up force was adopted as the blow-up occurrence threshold, and the point at which the predicted compressive force within the slab exceeded the blow-up force was identified as the blow-up occurrence time. RESULTS : Using the GWNU blow-up model, the blow-up occurrence on the Seohean Expressway in Korea is predicted in the presence or absence of the alkali-silica reaction (ASR). Analysis is conducted using the expansion joint spacing and width as variables. As the expansion joint spacing increases, blow-up occurs sooner, and as the width increases, only the expansion joint life decreases. When applying an expansion joint spacing of 300 m and a width of 100 mm under an ASR with 99.9% TTPG reliability, the sum of the expansion joint life and blow-up occurrence time is 16 years. CONCLUSIONS : In the case of jointed concrete pavements where ASR occurred, installing an expansion joint spacing of 300 m and a width of 100 mm does not satisfy the design life of 20 years, and the expansion joint width minimally affect the blow-up occurrence time. To prevent blow-up incidents, a spacing of less than 300 m for the expansion joint is recommended. Based on the analysis results, the blow-up occurrence time and location can be predicted from the characteristics of the installed expansion joint, through which blow-up incidents can be prevented via preliminary maintenance.

본 연구는 광시성(广西省)을 사례로 중국의 아세안 국가에 대한 고등교 육 협력 정책을 분석하는 데 목적이 있다. 연구 결과, 광시성은 중국 중서 부와 해상 실크로드를 연결하는 관문이라는 지정학적인 위치를 적극 활용 해 아세안 국가를 대상으로 한 고등교육 협력을 강화하고 있다. 중국 중앙 정부는 국가 전략적으로 광시성에 해상 실크로드 전략 중 ‘민심상통’에 토 대가 되는 아세안과의 고등교육 협력 강화를 중점 과업으로 부여하고, 광 시성 지방정부는 지역이 가지는 지경학적 특성을 고려해 아세안 국가를 대상으로 고등교육 협력을 강화하고 있다. 구체적으로 보면, 광시성은 “유 학 광시”를 브랜드화해 아세안 국가 학생을 유치하고, 아세안 국가 장학금 을 신설해 지원을 확대하고 있다. 또한 중국과 아세안과의 교역 관계와 산 업 분업구조가 심화함에 따라 아세안을 대상으로 한 직업교육을 강화해 일대일로 구축에 필요한 기술 인력을 양성하고 있다. 즉, 광시성의 아세안 국가와의 고등교육 협력은 자국 고등교육의 국제화 수준을 제고하는 한편 중국과 아세안과의 산업 분업구조에서 필요한 산학 인재를 육성하는 전초 기지로 역할하고 있다. 나아가 아세안과의 ‘교육 공동체’ 구축을 강화하고 있어 ‘중국몽’의 토대가 되는 ‘교육 강국’, ‘인류운명공동체’ 구축을 뒷받침 하고 있다.

In this study, we report the microstructural evolution and shear strength of an Sn-Sb alloy, used for die attach process as a solder layer of backside metal (BSM). The Sb content in the binary system was less than 1 at%. A chip with the Sn-Sb BSM was attached to a Ag plated Cu lead frame. The microstructure evolution was investigated after die bonding at 330 °C, die bonding and isothermal heat treatment at 330 °C for 5 min and wire bonding at 260 °C, respectively. At the interface between the chip and lead frame, Ni3Sn4 and Ag3Sn intermetallic compounds (IMCs) layers and pure Sn regions were confirmed after die bonding. When the isothermal heat treatment is conducted, pure Sn regions disappear at the interface because the Sn is consumed to form Ni3Sn4 and Ag3Sn IMCs. After the wire bonding process, the interface is composed of Ni3Sn4, Ag3Sn and (Ag,Cu)3Sn IMCs. The Sn-Sb BSM had a high maximum shear strength of 78.2 MPa, which is higher than the required specification of 6.2 MPa. In addition, it showed good wetting flow.

Plastics are widely used in industries in human society and because of their structural stability, degradation is a serious global issue. To estimate the degradation of plastic, 31 edible mushrooms were cultured with the selected plastic films (polyethylene [PE], polystyrene [PS], and poly(ethylene terephthalate) [PET]) for 3 months at 25 °C. Measuring the weight of the films showed that four species of mushrooms, namely Porostereum spadiceum, Ganoderma lucidum, Coprinellus micaceus, and Pleurotus ostreatus, exhibited the highest degrees of plastic degradation. In addition, the mushrooms and fungi that exhibited the most significant plastic degradation were cross-cultured to promote this degradation. As a result, cross-cultivation of G. lucidum and Aspergillus niger showed a weight loss of 2.49% for the PET film. For the PS film, Aspergillus nidulans showed a weight loss of 4.06%. Cross-cultivation of A. nidulans and C. micaceus, which showed a weight loss of 2.95%, was noted as an alternative for PS biodegradation, but is harmful to humans. These bio-degradation effects of edible mushroom will contribute to the development of alternatives for eco-friendly plastic degradation.

As a member of ectomycorrhizal fungi, Tricholoma matsutake has a symbiotic relationship with its host, Pinus densiflora. To cultivate T. matsutake artificially, the co-cultivation of T. matsutake mycelia and bacteria from shiro was introduced. In this study, bacteria were isolated from soil samples in Bonghwa-gun, and seven bacterial isolates (B22_7_B05, B22_7_B06, B22_7_B07, B22_7_B08, B22_7_B10, B22_7_B13, and B22_7_B14) promoted the growth of T. matsutake mycelia (147.48, 232.11, 266.72, 211.43, 175.17, 154.62, and 177.92%, respectively). Sequencing of the 16S rRNA region of the isolated bacteria was performed. B22_7_B05 and B22_7_B10 were identified as Bacillus toyonensis, B22_7_B06 and B22_7_B08 as Paenibacillus taichungensis, B22_7_B07 and B22_7_B14 as P. gorilla, and B22_7_B13 as P. odorifer. These bacterial isolates were associated with the shiro community and are expected to contribute to the cultivation of T. matsutake.

Tricholoma matsutake is a traditional favorite food in East Asia, cultivated in fairy rings called “shiro,” which are found near Pinus densiflora. For effective artificial cultivation of Tri. matsutake, microorganisms from symbiotic fairy rings are co-cultivated. In this study, one bacterial isolate (Y22_B35) and two fungal isolates (Y22_F64 and Y22_F68) displayed growth-promoting effects on Tri. matsutake mycelium (158.47, 125.00, and 122.26% enhanced growth, respectively). For identification, 16S rRNA or ITS regions from the microorganisms¡¯ genomes were sequenced. Other sequences, including BenA, CaM, and RPB2 were sequenced in the fungal isolates. The bacterial isolate Y22_B35 was identified as Bacillus cereus. Y22_F64 and Y22_F68 were identified as Umbelopsis nana and Aspergillus parvulus, respectively. To identify the effects of the dominant microorganisms on Tri. Matsutake cultivation, metagenomic analyses were performed. Discovery of these Tri. matsutake mycelium growth-promoting microorganisms and metagenomics analyses are expected to contribute to our understanding of Tri. matsutake fruiting body growth and construction of biomimicry.

In this study, the expression of genes related to fruit ripening was investigated using realtime PCR. The study aimed to determine the effective conditions of calcium compounds (Calcium citrate, calcium chloride, calcium nitrate, GH-Ca, OS-Ca) and chitosan treatment to extend the shelf-life in the ‘Kumhong’ nectarine and ‘Madoka’ peach fruits. In this study, in the ‘Kumhong’ and ‘Madoka’ fruits, the expression of genes related to cell wall degradation, pectin lyase (PL), polygalacturonase (PG), and pectin methylesterase (PME), was inhibited by calcium, chitosan, or a mixture (Chitosan+CaCl2) treatment. In ‘Madoka’ peach, although the expression of the PG gene was suppressed at pre-harvest Ca and chitosan treatment, the expression of the PL gene was induced at pre- and post-harvest Ca and chitosan treatment compared to the control. The spray of calcium, chitosan itself, or a mixture (Chitosan+ CaCl2) on the trees at the ripening stage and harvested fruits can extend the shelf-life by suppressing the expression of cell wall degrading enzymes genes (PL, PG, PME) in ‘Kumhong’ nectarine and ‘Madoka’ peach tree. These results provide valuable information for the development of technology for the extension of the shelf-life of peach and nectarine fruits.

This study addresses the environmental impact associated with waste management and natural aggregate production. It explores the potential of utilizing Coal Bottom Ash (CBA) and Reclaimed Asphalt Pavement Aggregate (RAPA) as complete replacements, respectively, for fine and coarse aggregates in concrete. Despite their similarities to natural aggregates, CBA and RAPA often end up in landfills. Laboratory tests were conducted, revealing satisfactory performance in drying shrinkage and air void parameters. However, while the flexural strength met design requirements, the compressive and splitting tensile strengths were lower than predicted. The deviation in strength development behavior from natural aggregate concrete (NAC) was attributed to weak agglomerated aggregates in RAPA and the large size of the interfacial transition zone (ITZ) due to the old asphalt coating surrounding RAPA. To enhance the strength behavior, two methods were employed: compaction in the form of roller-compacted concrete and RAPA abrasion carried out by rolling RAPA in a concrete mixer. Compaction improved aggregate interlock, while RAPA abrasion decreased agglomerated aggregates and minimized asphalt coating, reducing ITZ size. These treatments resulted in improvements in compressive, flexural, and splitting tensile strengths, with the combination of both treatments having the most significant effect. Analysis of relationships between flexural, splitting tensile, and compressive strengths indicated that CBA and RAPA concrete behaved more similarly to NAC after the treatments. This research suggests that with appropriate interventions, it is feasible to utilize CBA and RAPA in concrete, contributing to sustainable construction through improved waste management, carbon footprint reduction, and conservation of natural resources.

Acknowledging the limited opportunities faced by learners of Korean in the US, this study investigates the efficacy and challenges of immersive Korean language-focus residential programs in US college dormitories. Through an examination of a Korean language dormitory (called K-house) at a Midwestern university in the US, the current study sheds light on the optimal experiences and effective immersive environments that college langauge dormitory programs in the US can foster for both linguistic and cultural learning of Korean. By delving deeper into the specific programming and experiences of K-house residents, the study demonstrates that K-house facilitates access to Korean language and culture, enhances motivation of Korean language study, and cultivates a sense of belonging to the K-house community among K-house residents. Additionally, the findings of this study provide valuable insights for designing effective Korean language dormitory programs that promote language and cultural immersion in the context of teaching and learning Korean as a foreign language. Furthermore, this study offers suggestions for future research in this area.

In this study, we proposed a novel concept of liquid level indicator that can stably measure the liquid level even with changes in liquid density by enormous temperature changes. This uses a distributed optical fiber sensor based on Rayleigh scattering with high spatial resolution. Additionally, taking advantage of the flexibility of an optical fiber sensor, we introduced a bendable supporting structure and made it possible to freely adjust the angle for ease of installation of the liquid level indicator. In the proof-of-concept experiment using a prototype incorporating the proposed concept, we confirmed that the interface location can be effectively detected by utilizing the difference in heat transfer characteristics between liquid and gas phases, demonstrating the feasibility of liquid level measurement. Such a liquid level indicator is expected to enable more accurate level measurements in environments with huge temperature changes and to be conveniently used even in situations where installation and maintenance of the level meter are challenging due to complex internal structures.

Gastrodia elata has been used in traditional Chinese medicine for treating headaches, dizziness, and convulsive illness for centuries. G. elata has traditionally been processed by steaming or blanching to increase the content and quality of its main ingredients. This study aimed to identify changes in physicochemical properties and active ingredients of G. elata depending on the steaming time. Data of this study could be used to develop traditional medicine and health foods. No steaming was used as a control. Steaming time was 5, 10, 20, 30, 60, or 120 min. The drying yield according to the steaming time ranged from 20.2% to 22.9%, with the lowest drying yield at 120 min. As the steaming time increased, gastrodin content increased more than that in fresh G. elata due to inhibition of β-glucosidase enzyme activity, 4-hydroxybenzyl alcohol condensation, and parishin decomposition. Steamed G. elata did not show higher total polyphenols, total flavonoids, or ABTS radical scavenging activities than fresh G. elata even with an increase of steaming time. The steaming time to improve the quality of G. elata may varied depending on the size of G. elata. Thus, it is important to set the steaming time taking these characteristics into consideration.

Friction stir spot welding (FSSW) is a solid-state joining process and a rapidly growing dissimilar material welding technology for joining metallic alloys in the automotive industry. Welding tool shape and process conditions must be appropriately controlled to obtain high bonding characteristics. In this study, FSSW is performed on dissimilar materials AA5052-H32 aluminum alloy sheet and SPRC440 steel sheet, and the influence of the shape of joining tool and tool insertion depth during joining is investigated. A new intermetallic compound is produced at the aluminum and steel sheets joint. When the insertion depth of the tool is insufficient, the intermetallic compound between the two sheets did not form uniformly. As the insertion depth increased, the intermetallic compound layer become uniform and continuous. The joint specimen shows higher values of tensile shear load as the diameter and insertion depth of the tool increase. This shows that the uniform formation of the intermetallic compound strengthens the bonding force between the joining specimens and increases the tensile shear load.

한국 남해 동부 해역인 통영해역에 설치된 연안 수온 분석 결과, 태풍이 남해안에 상륙하기 전에 수온이 급격하게 상승한 것으 로 나타났다. 수온 상승은 표층(5m)은 물론 저층(15m)까지 같이 발생하였다. NOAA 위성에서 관측한 표면수온자료 분석 결과, 태풍이 상 륙하기 전 한국 남해 동부 해역의 동쪽 해역에 30℃의 수온을 가지는 해수가 존재하였다. 한국 남동해역은 대마난류에 의해 서쪽에서 동 쪽으로 해류가 우세한 지역이나 위성 자료 분석 결과, 30℃의 해수는 동쪽에서 서쪽으로 이동한 것으로 나타나 태풍 상륙 전에 태풍에 의 한 에크만 수송의 영향을 받은 것으로 나타났다. 또한 남해 동부 해역은 한국 동해 해역과 달리 수심이 깊지 않기 때문에 바람에 의한 연 직 혼합으로 인해 전 수층의 수온이 일정하게 나타날 수 있다. 수층별 수온 상승이 같은 날에 발생하였기 때문에 저층 수온 상승은 연직 혼합에 의한 결과라 볼 수 있다. 따라서 한국 남동해역은 태풍의 접근 방향과 고수온의 형성 위치에 따라 에크만 수송에 의해 수온이 급 상승할 수 있는 해역임을 알 수 있다.

Fluorine-doped tin oxide (FTO) has been used as a representative transparent conductive oxide (TCO) in various optoelectronic applications, including light emitting diodes, solar cells, photo-detectors, and electrochromic devices. The FTO plays an important role in providing electron transfer between active layers and external circuits while maintaining high transmittance in the devices. Herein, we report the effects of substrate rotation speed on the electrical and optical properties of FTO films during ultrasonic spray pyrolysis deposition (USPD). The substrate rotation speeds were adjusted to 2, 6, 10, and 14 rpm. As the substrate rotation speed increased from 2 to 14 rpm, the FTO films exhibited different film morphologies, including crystallite size, surface roughness, crystal texture, and film thickness. This FTO film engineering can be attributed to the variable nucleation and growth behaviors of FTO crystallites according to substrate rotation speeds during USPD. Among the FTO films with different substrate rotation speeds, the FTO film fabricated at 6 rpm showed the best optimized TCO characteristics when considering both electrical (sheet resistance of 13.73 Ω/□) and optical (average transmittance of 86.76 % at 400~700 nm) properties with a figure of merit (0.018 Ω-1).

고등학생의 시기에서는 대인관계가 매우 중요한 역할을 수행한다. 하지만, 불안정한 대인관계는 심리정서적 문제를 유발하는 등 부정적 문제를 유발할 수 있다. 대인관계에 있어 심리정서적 측면을 남성 보다 더 고려하는 여자 고등학생들의 특성에 기초하여 이러한 문제는 두드러질 수 있다. 본 연구는 여자 고등학생들의 대인관계의 질이 스마트폰 과의존에 영향을 미치는지 분석 하는데 목적이 있다. 연구대상은 J시 W고등학교에 재학 중인 여자 고등학생 53명이다. 대인관계의 질은 Korean ver. of Friendship Quality Questionnaire를 활용하여 조사하였다. 대인관계의 질은 21문항이며, 5점 척도로 점수가 높으면 높을수록 대인관계의 질이 높음을 의미한다. 스마트폰 과의존은 스마트폰 과의존 척도를 활용하여 조사하였다. 스마 트폰 과의존은 10문항이며, 4점 척도로 점수가 높으면 스마트폰 과의존 수준이 높음을 의미한다. 그 결과, 대인관계의 질이 스마트폰 과의존에 부적 (-) 영향을 미치는 것으로 나타났다. 이러한 결과는 대인관계의 질이 높아질수록 스마트폰 과의존 수준이 저하된다고 설명할 수 있다. 이에 기초하여, 여자 고등학생들의 대인관계, 스마트폰 사용과 관련한 교육과 접근에 있어서 이러한 결과를 고려해야 할 것이며, 대인관계를 향상시킬 수 있는 접근이 필요할 것이다. 후속 연구들에서는 대상의 범위를 확대하여 다양한 대상군들과 비교 분석할 필요가 있으며, 스마트폰 과의존과 대인관계의 질의 관계에 있어서 영향을 미칠 수 있는 다양 한 변수들을 고려한 심층 분석연구들이 수행되어야 할 것이다.
