스마트팜으로 알려진 지능형 온실환경 제어(스마트제어)가 겨울철 장미 ‘비스트’의 절화품질에 미치는 영향을 기존의 농 가 수동제어(수동제어)와 비교하여 조사하였다. 그 결과 지능 형 스마트제어가 온실환경인 기온, 배지온도, 상대습도를 겨 울철 절화 장미 생산에 적합하게 유지시켰다. 반면, 수동제어 는 적정한 환기와 상대습도 관리에 다소 불리하였고, 결과적 으로 겨울철 과습으로 흔히 발생하는 잿빛곰팡이 발병이 증가 했으며 절화수명이 단축되었다. 절화의 생체량, 길이, 수명 등 절화품질 역시 스마트제어를 통해 상대적으로 개선되었다. 이 번 연구를 통해 스마트제어 방식이 시설환경관리 측면에서 겨 울철 고품질 절화 장미 생산에 유리하다는 것을 확인하였다.

Black soldier fly (BSF, Hermetia illucens) has been noted as an excellent feed ingredient. However, there is limited information on rearing and processing technology. Thus, this study was conducted to evaluate the substrates for rearing BSF and the optimal processing method for BSF performance. Study separated as 2 experiment, BSF rearing and drying method(Exp 1.) and EP-processing method(exp 2.). During the study, 30 clutches were reared, with 10 per substrate. Three substrates, namely food waste (FW), tofu by-product (TF), and vegetable waste with two drying methods, namely hot air dry (AD) and microwave dry (MW) at expanding (EP) ratios of 5:5 and 7:3, were examined by evaluating their rearing performance, nutrient contents, in vitro digestibility and lipid oxidation stability during storage (0, 14 and 28 days). In experiment 1, the rearing substrates and drying methods were evaluated. Compared with that of conventional methods (FW, AD), the TF substrates and MW method showed higher dry matter contents (3.43%) and in vitro digestibility (1.62%) but lower ether extract contents(3.53%; p<0.05). However, the malondialdehyde (MDA) concentration under MW treatments decreased during storage (5.77%, 4.69% and 3.24%; p<0.05). In experiment 2, compared with that of the 7:3 EP-BSF ratio, the 5:5 EP-BSF ratio showed higher in vitro digestibility (2.70%) and lower MDA concentration during storage (19.19%, 7.96% and 6.42%; p<0.05). In conclusion, the optimal conditions for BSF rearing and ensuring product quality were TF substrates, MW methods and a 5:5 corn:BSF ratio. Therefore, the optimal conditions for producing EP-BSF can present an excellent feed ingredient alternative for swine feed.

생태계서비스란 자연생태계가 인간에게 주는 혜택을 통틀어 일컫는 용어이다. 생태계서비스를 정량화하기 위하여 다양한 모형이 개발되어 적용되고 있다. InVEST는 대표적인 생태계서비스 모형이며 그 중 서식지질 평가가 폭넓게 사용되고 있다. 우리나라에서는 국립공원을 대상으로 서식지질 평가가 실시되고 있다. 서식지질 평가를 위해서는 서식 지질 초기값으로 위협인자에 대한 민감도 평가가 이뤄져야 하는데, 이는 국가 및 적용분야에 따라 판이하다. 그래서 그동안 진행된 국립공원 서식지질 평가를 바탕으로 전문가 설문(AHP)을 실시하여 서식지질 초기값인 민감도의 기준을 조정하였다. AHP실시 결과 자연초지, 경지정리가 안된 밭 등 10개 항목이 상향조정되었으며, 하천, 호소 등 8개 항목이 하향조정되어 총 18개 항목이 조정되었다. 조정된 민감도 결과를 바탕으로 도시형인 북한산국립공원과 계룡산국립공 원, 사적형인 경주국립공원, 해상해안형인 한려해상국립공원 그리고 산악형인 지리산국립공원과 설악산국립공원을 대상지 서식지질 분석을 실시하였다. 분석결과 국립공원내 분포하는 시가화건조지역과 수역에 대한 부분이 서식지질 평가에 반영되었음을 알 수 있었다. 향후 이 기준을 이용하여 자연공원의 서식지질 평가가 가능할 것이다.

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.

Occurrence of process environment changes, such as influent load variances and process condition changes, can reduce treatment efficiency, increasing effluent water quality. In order to prevent exceeding effluent standards, it is necessary to manage effluent water quality based on process operation data including influent and process condition before exceeding occur. Accordingly, the development of the effluent water quality prediction system and the application of technology to wastewater treatment processes are getting attention. Therefore, in this study, through the multi-channel measuring instruments in the bio-reactor and smart multi-item water quality sensors (location in bio-reactor influent/effluent) were installed in The Seonam water recycling center #2 treatment plant series 3, it was collected water quality data centering around COD, T-N. Using the collected data, the artificial intelligence-based effluent quality prediction model was developed, and relative errors were compared with effluent TMS measurement data. Through relative error comparison, the applicability of the artificial intelligence-based effluent water quality prediction model in wastewater treatment process was reviewed.

This research investigated the preparation of activated carbon derived from Krabok (Irvingia malayana) seed shells to improve the quality of crude glycerol obtained during biodiesel production. The activated carbon was prepared using a dry chemical activation method with NaOH, utilizing an innovative biomass incinerator. The results revealed that the resulting KC/AC-two-step exhibited favorable physicochemical adsorption properties, with a high surface area of 758.72 m2/g and an iodine number of 611.10 mg/g. These values meet the criteria of the industrial product standard for activated carbon No. TIS 900-2004, as specified by the Ministry of Industry in Thailand. Additionally, the adsorption efficiency for methylene blue reached an impressive 99.35 %. This developed activated carbon was then used to improve the quality of crude glycerol obtained from biodiesel production. The experimental results showed that the KC/AC-two-step increased the purity of crude glycerol to 73.61 %. In comparison, commercially available activated carbon (C/AC) resulted in a higher crude glycerol purity of 81.19 %, as analyzed by the GC technique. Additionally, the metal content (Zn, Cu, Fe, Pb, Cd, and Na) in purified glycerol using KC/AC-two-step was below the standards for heavy metals permitted in food and cosmeceuticals by the Food and Drug Administration of Thailand and the European Committee for Food Contact Materials and Articles. As a result, it can be inferred that Krabok seed shells have favorable properties for producing activated carbon suitable as an adsorbent to enhance crude glycerol purity. Furthermore, the improved crude glycerol from this research has potential for various industrial applications.

High-quality diamond films have attracted extensive attentions due to their excellent optical and electrical properties. However, several issues, such as random orientation, stress accumulation, and slow growth rate, severely limit its applications. In this paper, high-quality polycrystalline diamond films with highly ordered (100) orientation were prepared by microwave plasma chemical vapor deposition. The effects of growth parameters on the microstructure, quality and residual stress of diamond films were investigated. Experimental results indicate that relatively high temperature at low methane concentration will promote the formation of (100) oriented grains with a low compressive stress. Optimized growth parameters, a methane concentration of 2% along with a pressure of 250 Torr and temperature at 1050 ℃, were used to acquire high growth rate of 7.9 μm/h and narrow full width at half maximum of Raman peak of 5.5 cm− 1 revealing a high crystal quality. It demonstrates a promising method for rapid growth of high-quality polycrystalline diamond films with (100) orientation, which is vital for improving the diamond related applications at low cost.

This study examined the impact of two bacterial strains, H05E-12 and H05R- 04, on alleviating non-irrigation-induced stress and its subsequent effects on the fruit productivity of sweet pumpkin plants. When subjected to non-irrigation-induced stress, the lipid peroxidation, proline, total phenol, and total soluble sugar content significantly decreased in plants treated with either H05E-12 or H05R-04 compared to the control. In a greenhouse experiment under non-irrigated conditions, H05E-12-treated plants exhibited higher stomatal conductance than the control, although there was no significant change in the soil plant analysis development (SPAD) value due to treatment. Upon re-watering, an increase in fruit diameter was observed in H05E-12-treated plants, and the L-ascorbic acid content in the fruit also showed a significant increase compared to the control. The H05E-12 strain was identified as Kushneria konosiri. To the best of our knowledge, this is the first report detailing the beneficial effects of K. konosiri on the alleviation of non-irrigation-induced stress and the promotion of plant growth in sweet pumpkin plants.

Abstract Purpose : This study was conducted to determine the effect of cataracts on quality of life in adults over 40 years of age using raw data from the 7th National Health and Nutrition Survey (2016-2018). Methods : We analyzed the relationship between gender, age, depression, and illness-related quality of life among 4,394 adults aged 40 years and older who responded to a diagnosis of cataract in the 7th National Health and Nutrition Examination Survey (2016-2018). Dichotomized variables were analyzed using the chi-square test (X2). Relationships between cataract, depression, and quality of life sub-variables were analyzed using logistic regression, adjusting for the effects of age and gender. A value of p<0.05 was considered significant. Results : In the logistic regression analysis results corrected for age and gender, cataracts were significantly related to cataracts in terms of motor ability (walking activity), pain and discomfort, anxiety and depression. In terms of restrictions on motor ability (walking activity), cataract disease patients were 1.37 times (95% CI: 1.14-1.65), pain and discomfort were 1.3 times (95% CI: 1.11-1.51), and anxiety and depressive symptoms were 1.38 times (95% CI: 1.10-3.75) at increased risk, confirming that cataracts significantly lowered the quality of life of the subjects. However, in terms of self-care (bath or dressing) and daily life, after correcting age and gender, a significant relationship with cataracts could not be confirmed. Conclusion : It was confirmed that cataracts affect exercise ability, pain/comfort, anxiety/ depression, etc., which can also reduce the quality of life.

이 연구는 1세대 스마트 온실의 재배환경 데이터와 장미 절 화의 품질 특성 데이터를 수집하고 그 요인들 간의 상관 관계 를 분석하여 절화수명 예측 및 최적 환경 조성의 기초 자료를 얻고자 수행되었다. 이를 위해, 토경재배(SC) 및 암면배지경 양액재배(RWH) 하우스 각 1개소를 선정하여 1년간 기온, 상 대습도(RH) 및 수증기압차(VPD), 일적산광량(DLI), 근권온도 등의 환경 데이터와 매월 말 수확된 장미 ‘Miss Holland’ 절 화의 품질 특성 데이터를 수집하였으며, 이 데이터와 절화수 명과의 상관관계를 분석하였다. 절화수명은 10월과 11월을 제외하고는 SC 하우스에서 RWH 하우스보다 더 길었다. 절 화수명과 환경 및 생육 특성 간의 상관관계 분석에서 SC 하우 스의 상관계수는 RWH 하우스보다 조금 더 높았으며, 절화수 명 예측을 위한 요소들도 두 하우스 간에 차이가 있었다. SC 하우스의 절화수명 Y=0.848X1+0.366X2-0.591X3+2.224X4- 0.171X5+0.47X6+0.321X7+9.836X8-110.219(X1-X8: 최고 RH, RH 일교차, DLI, pH, Hunter’s b value, EC, 절화 장, 잎 두께; R2=0.544)로 예측되었고, RWH 하우스의 절화수명 Y=-1.291X1+52.026X2-0.094X3+0.448X4-3.84X5+0.624X6 - 8.528X7+28.45(X1-X7: 경경, 야간 VPD, 최고 근권온도, 최 저 근권온도, 기온 일교차, RH 일교차, 최고 VPD; R2=0.5243) 로 예측되었다. 이 두 모델식으로부터 SC 하우스에서는 RH, EC 및 pH가, 그리고 RWH 하우스에서는 근권 온도가 절화수명에 더 큰 영향을 미친다는 것을 추론할 수 있다. 따라서 각 재배 방법에 따라 장미의 절화수명에 더 큰 영향을 미치는 환경적 요인을 효율적으로 관리할 필요가 있다.

본 연구는 생육시기별 한지형 잔디인 왕포아풀에 생장조정 제 trinexapac-ethyl(TE)과 prohexadione-calcium(PC) 을 처리 시 잔디의 품질 변화와 생장 억제 효과를 조사하였다. 처리구는 대조구와 생장조정제 처리구인 TE 처리구와 PC처리 구로 설정하였다. 1차 시험(여름철, 8월)과 2차 시험(가을철, 10월) 조사에서 대조구와 비교하였을 때, 왕포아풀의 가시적 품질 및 엽록소 함량은 통계적으로 유의적인 차이는 없었고, 약해는 발생하지 않았다. TE와 PC처리 후 28일 경과 시 잔디 초장은 1차 시험에서 대조구보다 각각 34.9%와 32.2% 정도, 2차 시험에서는 35.5%와 33.8% 정도 감소하였다. 대조구와 비교 시 TE와 PC처리구의 잔디 예지물은 1차 시험에서 각각 47.2%와 45.0%씩, 2차 시험에서 35.6%와 31.0%씩 감소되 었다. 생육시기별 비교에서 TE는 약제처리 후 28일 경과 시, PC는 7일 경과 시 각각 1차 시험에서 생장 억제 효과를 나타 냈다. 상기 결과들의 종합한 결과는 TE와 PC 처리 시 왕포아 풀에서 약해가 발생하지 않았고, 잔디의 경엽신장과 예지물을 감소시키는 것을 확인하였다. 또한, 생장조정제는 잔디 관리 에서 여름철과 가을철 모두 이용할 수 있으나 여름철에 생육 억제 효과가 높게 나타났다.

In this paper, we present a case study of developing MVIS (Machine Vision Inspection System) designed for exterior quality inspection of stamping dies used in the production of automotive exterior components in a small to medium-sized factory. While the primary processes within the factory, including machining, transportation, and loading, have been automated using PLCs, CNC machines, and robots, the final quality inspection process still relies on manual labor. We implement the MVIS with general- purpose industrial cameras and Python-based open-source libraries and frameworks for rapid and low-cost development. The MVIS can play a major role on improving throughput and lead time of stamping dies. Furthermore, the processed inspection images can be leveraged for future process monitoring and improvement by applying deep learning techniques.

Approximately 40,000 elevators are installed every year in Korea, and they are used as a convenient means of transportation in daily life. However, the continuous increase in elevators has a social problem of increased safety accidents behind the functional aspect of convenience. There is an emerging need to induce preemptive and active elevator safety management by elevator management entities by strengthening the management of poorly managed elevators. Therefore, this study examines domestic research cases related to the evaluation items of the elevator safety quality rating system conducted in previous studies, and develops a statistical model that can examine the effect of elevator maintenance quality as a result of the safety management of the elevator management entity. We review two types: odds ratio analysis and logistic regression analysis models.

Mid-sized manufacturing companies, which account for 0.7%(5,480 companies), 13.8%(1.169 million persons) of total employment, and 15.7% of total sales, have recently experienced a lot of difficulties in management activities due to the impact of COVID-19, the U.S.-China trade war, and the collapse of global supply chains. To overcome this, revitalization of quality management activities to strengthen corporate competitiveness is emerging as an urgent task. In order for these quality management activities to achieve their intended purpose, the positive leadership of corporate managers is very important above all else. There have been many studies related to positive leadership, but most have focused on charismatic leadership and transformational leadership centered on large companies or small and medium-sized enterprises. Therefore, this study aims to present ways to strengthen the leadership of managers by empirically analyzing how the positive leadership of managers of mid-sized manufacturing companies, which was relatively under-researched, affects quality management activities and Business performance(Balanced Score Card; BSC).

In this study, we have developed a movable defect detection system based on a vision module with machine-learning algorithm for distinguishing product quality. Machine-learning model determined the results in good or no good through images acquired from the vision module consisting of a camera, processor unit, and lighting. To ensure versatility for use in a variety of settings, we have integrated a robot arm and cart for the movable defect detection system, and the robot arm that adjusts the focus length is made to be able to rotate in all directions. The type of defect was divided into eccentricity defect and printing defect. As a result, it was confirmed that classification accuracy showed 0.9901 in our developed device.

The aim of this study was to determine the quality characteristics of bread with 2%, 4%, 6%, and 8% cuttlefish ink added. The pH of the dough decreased as the addition percentage increased, and the addition of 8% was the lowest. The pH of the bread and the fermentation expansion power of the dough decreased as the addition percentage increased. Moisture and ash content were positively correlated with the addition percentage, and the crude protein and crude ash content were negatively correlated. As the addition percentage increased, the color of the bread became darker, and the bread volume decreased. The inside and outside color of the bread also decreased as the addition percentage increased. The volume and specific volume of bread decreased as the addition percentage increased. The amino acid analysis indicated glutamic acid was the largest, free amino acid analysis pointed out aspartic acid the highest. The springiness, cohesiveness, gumminess, brittleness, and hardness of the bread were positively correlated with the addition percentage. Overall, it seems possible to develop bakery items using cuttlefish ink as a functional ingredient.

In this study, quality properties of rapeseed oil by different roasting temperatures (140, 160, 180, and 200℃) were investigated. Roasted-pressed oil (RPO) showed a decrease in lightness and an increase in redness and yellowness with an increase in temperature compared to cold-pressed oil (CPO). In addition, the β-carotene and tocopherol content also increased in RPO as the roasting temperature increased. The tocopherol content increased by 18~20% in RPO at 200℃ compared to CPO. This increase in bioactive components led to improved radical scavenging activity dependent on roasting temperature, and RPO at 200°C showed a 2.7-fold improvement compared to CPO. Finally, it was observed that higher roasting temperatures resulted in an extended oxidation induction period, increasing by up to 3.3 times. In conclusion, roasting is an effective method for enhancing the oil functionality of domestic rapeseed varieties. This study provides basic data for producing high-quality oil.

This study investigated the quality characteristics and antioxidant activities of salad dressing prepared with Jerusalem artichoke powder (0%, 4%, 8%, and 12%). The pH, soluble solid content, and viscosity increased as the content of Jerusalem artichoke powder increased. The titratable acidity showed no significant differences between samples. The lightness values decreased, while the redness and yellowness values increased with increasing amounts of Jerusalem artichoke powder. The total polyphenol content ranged from 52.00-69.64 μg GAE/g, and increased with the increase in Jerusalem artichoke powder levels. The antioxidant activities measured via DPPH and ABTS radical scavenging activity and reducing power also increased with increasing Jerusalem artichoke powder, at a higher rate than in the control. These results suggest that it is beneficial to add Jerusalem artichoke powder when in salad dressing.
