One of noticeable features in the cross flow fan is that a working fluid passes through impeller blade twice without distinction between the inlet and exit angles. Also, it does produce higher circumferential velocity than other types of blade at the same flow rate in accordance with the application of the forward curved shape. However, a design theory for the cross-flow fan has not yet been formed owing to an eccentric vortex, which is the remarkable characteristics, occurred in a cross-flow fan. Furthermore, the eccentric vortex, which is difficult to control the size and position, is the important cause of performance decrease. In this study, experiments are carried out to estimate the similarity of the cross-flow fan with various scales and rotational velocity changes. Pressure coefficients to flow coefficients with various scales of the cross-flow fan are plotted to the application of the general similarity law of the turbomachinery in the cross-flow fan with Archimedes spiral, which is the important factor having an effect on it.

Left Upper Lobar Agenesis Associated with Tracheal Trifurcation: A Case Report

김형섭,우정주,안진경 대한영상의학회 2019 대한영상의학회지 Vol.80 No.3

Lobar agenesis is a rare congenital anomaly that is characterized by the absence of the lobar pulmonary artery, pulmonary vein, bronchi, and parenchyma. We encountered a unique case of a young male patient with agenesis of the left upper lobe with tracheal trifurcation into three bronchi, all arising at the carinal level. Complex tracheobronchial anatomy was explicitly demonstrated by three-dimensional CT reconstruction and virtual bronchoscopy. Left upper lobar agenesis associated with tracheal trifurcation is an extremely rare anomaly that, to the best of our knowledge, has not been previously reported.

Objective: To investigate the possible relationship between the anthropometric data, the foot types, sex and the dynamic plantar pressure of normally developed teenagers. Method: The height, weight, body mass index and dynamic plantar pressure were measured from 98 teenagers. Foot types were classified to high arch, normal and flat foot groups depending on the value derived by dividing the minimal length of mid foot area by the maximal length of the rear foot area. Results: The area with the highest plantar pressure was the middle metatarsal area at both feet. However the plantar pressure of the right medial metatarsal and lateral calcaneal areas was greater than the left, while the plantar pressure of the left lateral metatarsal and medial calcaneal areas was greater than the right. Therefore, supinating and pronating forces were applied to the right and left feet. There were statistically significant differences in body weight and BMI among three groups. The comparison between men and women in plantar pressure measurements and foot type determinations showed that the number of pronated feet group and plantar pressures was greater in males than in females. Conclusion: The dynamic plantar pressure of teenagers showed high correlation to weight and BMI. Just like the hands, there was lateral dominance at the feet, and analysis of dynamic plantar pressure of each foot showed asymmetry and asymmetrical turning forces.

In the history of Japanese literature, Tanaka Hidemitsu is classified as a Buraiha writer. The Buraiha writers include Osamu Dazai, who made his debut as a writer by recommending Hidemitsu novels, as well as Ishikawa Jun, Oda Sakunosuke, and Sakaguchi Ango. Although Hidemitsu was not as much as the mainstream writers of Buraiha, the battlefield experience by participating in the life of Chosun during the Japanese occupation and during the Sino-Japanese War, It is a part of literature. Hidemitsu acted as a standing secretary of the Chosun Literary Society, which led the colonial Chosun in the wartime system. He collaborated with the literary system of the literary men who were promoted by the Japanese imperialism at the time and the literary magazine ‘National Literature’ as the central axis. In this study, we focus on the three aspects of the novels of Hidemitsu in the literary magazine "National Literature", seven articles, and the two lectures. Let's look closely. Unlike his published works for postwar self-excuse and justification, Hidemitsu's novels, articles, and his words and writings in the discussions reflect the way in which the society of the time was reflected, We will consider whether it is equipped. Through this, we want to approach the real meaning of what the Japanese writer Hidemitsu who lived at one point of Chosun society during the Japanese colonial period is throwing a message to us today and how to interpret and accept it.

This paper examines the affinities and cultural cognates between Slavs and Indo-Aryans from a perspective of Slavic mythology, comparative linguistics, and comparative cultural studies, etc. Of Proto-Indo-European Language Family, Slavic group belongs to the Satem Language group like Indo-Iranian(>Indo-Aryan, Iranian, Nuristani) group. For this reason, there turned out to be many linguistic evidences and cognates that Slavic and Indo-Aryan languages can share in common. Apart from biological DNA analysis that Indo-Aryans are close to Slavs in DNA types, there should be the three factors to support that Slavs and Aryans had contacted a long time before and that moreover, they still have a variety of cognates in languages and cultures, especially, in mythology, too. First, this study takes an exemplary of mythological comparisons with Slavic and Indo-Aryan gods' names, their origins, and their symbols. Secondly, linguistic analysis to compare the two languages is the best way to prove the connections between Slavic and Aryan cultural cognates. Lastly, this research investigates many cultural cognates of living culture and cults, which still remain without being extinct both in Slavs and in Indo-Aryans.

It is the essay that I can scratch “Byoshorokushaku” of Masaok Siki to 127 times from May 5, 1902 to September 17 that is two days ago to die and published serially in newspaper of “Japan”. Siki writes one’s thought that I felt in everyday life through constant intellectual curiosity and the intuitive observation for things while fighting against sufferings from illness in the limited space of 6 shakus. Siki wrote in various fields such as artistic discussion of the recollection of the event that happened in the circumference, a present condition report, a haiku and the Noh. A term and the sentence about the religion appear on 27 times particularly in that, too. Generally, in the people who reached death, the person is going to get over physical mental pain through religious faith for the help of the Absolute by oneself. This report considered it how Siki in sufferings from illness received religion through the last sentence that he left. As a result, he is not going to demand sufferings from illness through religion or a religious life and, in the case of Siki, understands what he was going to overcome through an earnest desire and the will as the literary person whom he walked so far.

The essay that “Bokujuitteki” was published serially in “a Japanese newspaper” on 164 times from January 16, 1901 to July 2 of Shiki Masaoka appears. Shiki Masaoka is the last record sentence that he wrote in one’s sad state of mind that Ⅰ felt through this sentence seeing from a sickbed at. Generally, when the people have death close at hand, is religious; is converted, or is going to overcome one’s physical mental pain for relief of God. Shiki Masaoka who faced death recognized one’s illness pain in the last sentence that oneself left how, and this report considered it whether you received it in how one’s inside world. In this report, I considered it mainly on scenery of a background and the writings space of the writings that “Bokujuitteki” showed, a symptom of the illness pain, the conquest method of the illness pain, feelings about the illness pain. As a result, “Bokujuitteki” was a method only for Shiki Masaoka for Shiki Masaoka to endure sufferings from illness. In addition, it was a driving force for Shiki Masaoka to be able to tolerate it from s oneself pain.
