Social media is a form of communication based on the internet to share information through content and images. Their choice of profile images and type of image they post can be closely connected to their personality. The user posted images are designated as personality traits. The objective of this study is to predict five factor model personality dimensions from profile images by using deep learning and neural networks. Developed a deep learning framework-based neural network for personality prediction. The personality types of the Big Five Factor model can be quantified from user profile images. To measure the effectiveness, proposed two models using convolution Neural Networks to classify each personality of the user. Done performance analysis among two different models for efficiently predict personality traits from profile image. It was found that VGG-69 CNN models are best performing models for producing the classification accuracy of 91% to predict user personality traits.

Coverage-based software reliability growth models (SRGMs) have been developed and successfully applied in practice. Performance of a coverage-based SRG M depends on the coverage function employed by the SRGM. When the coverage function represents the coverage growth behavior well irrespective of type of the testing profile the corresponding coverage-based SRGM is expected to be widely applicable. This paper first conducts a study of selecting the most representative coverage functions among the available coverage functions. Then their performances are empirically evaluated and compared. The result provides a foundation for developing widely applicable coverage-based SRGMs and monitoring the progress of a testing process.

Human powered aircraft (HPA) is an airplane that uses only human power for its propulsion. The human power as a power resource and an engine produce the available power that is very crucial to the success of the HPA. In the present paper, the human power characteristics for completing the mission profile are discussed focusing on the take-off and climbing performance. The mission profile is designed by using an athlete's power generation. It is believed that present analysis can be helpful for the mission profile design and athletes exercise program development for the HPA competitions.

A method to compute the reactive powers of the added buses by the decoupled UPFC model for the optimal voltage profile is presented, by which the voltage magnitudes of PQ buses can get closer to the reference value(usually one p.u.). The performance index for assessing how much the voltage magnitude is closer to the reference value is defined as the squared sum of the present voltage minus the reference voltage multiplied by the weighting number associated with the relative importance of the buses. Numerical example in a 10-unit 39-bus power system with 2 UPFC's shows that the performance index can be very much reduced by operating multi UPFC's with the reactive powers for the optimal voltage profile proposed in this paper.

A reversible axial flow fan called jet fan has been widely used for longitudinal ventilation in road tunnels to secure a safe and comfortable environment cost-effectively. As shifting the flow direction is usually made by only switching the rotational direction of an electric motor due to heavy duty, rotor blades having identical aerodynamic performance for bidirectional flow should be necessary. However, such aerodynamically desirable blades haven't been developed sufficiently, since most of the related studies have been done from the viewpoint of unidirectional flow. In the present paper, we demonstrate a method to profile the blade section suitable for bidirectional flow, which is validated by studying the aerodynamic performances of rotor blades of a two-stage jet fan experimentally and numerically.

The auxiliary gas-shielded MAG (AMAG) process, which was devised to provide an argon-rich shielding environment using small amount of argon gas, was investigated experimentally to figure out its effects on metal transfer and weld quality. Proper conditions for the AMAG process including the argon gas ratio, position and direction of the auxiliary nozzle were determined experimentally. Performance of the AMAG process was compared with that of the double gas-shielded MAG(DMAG) and MAG processes by monitoring the bead profile, current and voltage waveforms. The AMAG process was found to provide better bead profile, more stable arc and wider operating range of spray transfer mode compared with the DMAG process. In general, performance of the AMAG process using the argon ratio of 30% was comparable to that of the MAG process using 80% argon and 20% CO₂ gas.

In recent years, BLE technology has received extensive attention and has been applied to all aspects of life. The existing BLE device has two methods, one is the connection method, and the other is a non-connection method. The representative profile of the connection method is the proximity file. The most typical example of Non-connection method BLE device is a beacon. However, they are both independent and have their own shortcomings. Connection method device can provide service for only one user, others can't use. Security performance of Non-connection method BLE device is poor and the device can't be controlled by the user. In this paper, a combination-mode BLE device profile design scheme is presented, which combines with the previous two methods, and solves the defaults. And We define a dual purpose advertising package that can be used in a normal environment as well as in a disaster environment. Finally, a unidirectional Control idea is proposed. Through performance evaluation, we found that the device has strong stability and low power consumption.

This study was conducted to determine the effects of dietary non-genetically modified organism (non-GMO) wheat-based diets on the growth performance, nutrient digestibility, blood profile and meat quality of grower-finisher pigs. A total of 70 [(Landrace × Yorkshire) × Duroc] growing pigs with an initial body weight of 26.15 ± 1.57 kg were used in a 112 day trial. The dietary treatments were as follows: (I) CD, corn-based diet and (II) non-GMO WD, a non-genetically modified organism wheat-based diet. Each treatment consisted of 7 replicate pens with 5 pigs per pen. In the current study, the pigs fed the corn-based diet had a higher body weight than the pigs fed the non-GMO wheat-based diet at day 21 and day 77 (p < 0.05). There was a significant difference in the average daily gain (ADG) during the first 21 days (p < 0.05). The non-GMO wheat-based diet had no effect on nutrient digestibility. In addition, the non-GMO wheat-based diet had no effect on the blood profile except for blood urea nitrogen (BUN) at d 21. In conclusion, the non-GMO wheat-based diet only had a slight effect on the growth performance of growing pigs but had no significant impact on the nutrient digestibility, fecal score, blood profile and meat quality of the pigs during the grower-finisher period.

본 연구는 전반적인 발달지연, 감각 예민성, 촉각 방어와 작업수행의 문제를 가진 골덴하르 증후군 아동에게 감각통합치료를 적용하여, 골덴하르 증후군 아동의 감각통합 치료적 중재 개입방향을 제시하고자 하였다. 본 증례 아동은 만 7세 10개월 남아로 학교와 일상생활에서, 놀이와 학습에 대한 어려움, 운동발달 지연을 주 호소로 하여 검사가 의뢰되었다. 감각통합치료를 위한 평가로 캐나다 작업수행 측정(Canadian Occupational Performance Measure)시 바른 자세로 한글 읽고 쓰기가 첫째 작업수행 목표로 나타났고, 단축 감각프로파일(Short Sensory Profile) 과 감각 인터뷰에서는 감각 예민성과 촉각 처리영역에서 확연한 차이로 감각통합치료 중재가 요구되었다. 발달 프로파일 -3(Developmental Profile -3)은 5개 발달영역에서 전반적인 발달 지연이 나타났고, 운동 숙련도 검사 (Bruininks-Oseretsky Test of Motor Proficiency-2)에서 운동발달 수준이 평균 이하로 나타났다. 본 증례 아동에 대한 감각통합 치료를 통해 전반적인 발달, 감각예민성, 촉각방어와 같은 감각조절 기능이 향상되고, 작업수행이 개선되는데 도움이 되었다. 본 사례연구를 통해서 국내 골덴하르 증후군 아동의 감각통합치료 접근법에 기초 자료가 될 것이라고 사료된다.
