  • Previously, only one species belonging to the genus Apophua was recorded from South Korea by Kim (1955). Here, six additional species, A. cicatricosa, A. evanescens, A. honmai, A. stena, A. sugaharai and A. tobensis, are reported for the first time in South Korea. In this paper, we provide a key to the Eastern Palaearctic species of Apophua and diagnoses, as well as photographs of South Korean species.

  • In this paper we proposed backward fuzzy Petri-net to diagnoses faults in power systems by using the time sequence information of protection system. As the complexity of power systems increases, especially in the case of multiple faults or incorrect operation of protective devices, fault diagnosis requires new and systematic methods to the reasoning process, which improves both its accuracy and its efficiency. The fuzzy Petri-net models of protection system are composed of the operating process of protective devices and the fault diagnosis process. Fault diagnosis model, which makes use of the nature of fuzzy Petri-net, is developed to overcome the drawbacks of methods that depend on operator knowledge. The proposed method can reduce processing time and increase accuracy when compared with the traditional methods. And also this method covers online processing of real-time data from SCADA (Supervisory Control and Data Acquisition)

  • Asynchronous digital circuits working in military and space environments are often subject to the adverse effects of radiation faults. In this paper, we propose a new hardening technique against radiation faults. The considered digital system has the structure of DMR (Double Modular Redundancy), in which two sub-systems conduct the same work simultaneously. Based on the output feedback, the proposed scheme diagnoses occurrences of radiation faults and realizes immediate recovery to the normal behavior by overriding parts of memory bits of the faulty sub-system. As a case study, the proposed control scheme is applied to an asynchronous dual ring counter implemented in VHDL code.

  • The fluorescence intensity of a single-stranded oligonucleotide containing a fluorene-labeled deoxyuridine $(U^{Fl})$ unit increases by only 1.5-fold upon formation of its perfectly matched duplex. To increase the fluorescence signal during hybridization, we positioned a quencher strand containing a deoxyguanine (dG) nucleobase, functioning as an internal quencher, opposite to the $U^{Fl}$ unit to reduce the intrinsic fluorescence upon hybridization with a probe. From an investigation of the optimal length of the quencher strand and the effect of the neighboring base sequence, we found that a short strand (five-nucleotide) containing all natural nucleotides and dG as an internal quencher was effective at reducing the intrinsic fluorescence of a linear beacon; it also exhibited high total discrimination factors for the formation of perfectly matched and single base-mismatched duplexes. Such assays that function based on clear changes in fluorescence in response to single-base nucleotide mutations would be useful tools for accelerating diagnoses related to various diseases.

  • Construction Cycle Trend Survey, which survey total value of orders and realized amounts monthly, is a valuable statistics that used to quick grasp or forecast the trend of domestic construction business. In recent periodical survey quality diagnoses, few professional users named a problem that Construction Cycle Trend Survey could not get together with the current state of the construction industry. This study examined weather Construction Cycle Trend Survey reflects the economic sentiment of construction business or not. Paired t test was performed between Construction Cycle Trend Survey and Construction Business Survey Index (CBSI), and significant differences were verified.

  • The Zopheridae Solier consisting of members from three previous families, Zopherinae Solier, Monommatinae Blanchard and Colydiinae Erichson, is considered the taxonomically most challenging group, and comprises more than 1,700 described species worldwide. The members of Zopheridae represent diverse morphological variations, and are difficult to separate morphologically from other tenebrionoid families. Two Zopheridae genera, Colobicus Latreille and Lasconotus Erichson, are identified for the first time in Korea, and two wood-boring species, C. hirtus (Rossi) and L. niponicus (Lewis), are newly reported in the Korean fauna. A key to the genera of Korean Zopheridae, and diagnoses, habitus photographs, and illustrations of diagnostic characters of the two species are provided.

  • We reviewed eight South Korean species of the genera Scambus Hartig, 1838 and Tromatobia $F{\ddot{o}}rster$, 1869. Among them, the Genus Scambus Hartig, 1838 is a moderately large group that includes 152 species worldwide. The South Korean genus Scambus Hartig, 1838 only includes one species, Scambus calobatus (Gravenhorst, 1829). The Tromatobia $F{\ddot{o}}rster$, 1869 group is a relatively small genus, including 33 worldwide species. This group is recorded for the first time from South Korea. Also, we report seven newly recorded species: Scambus nigricans (Thomson, 1877), Scambus vesicarius (Ratzeburg, 1844), Tromatobia flavistellata Uchida and Momoi, 1957, Tromatobia nipponica Uchida, 1928, Tromatobia ornata (Gravenhorst, 1829), Tromatobia ovivora (Boheman, 1821), and Tromatobia variabilis (Holmgren, 1856). A key to South Korean species of the genera Scambus Hartig, 1838 and Tromatobia $F{\ddot{o}}rster$, 1869, diagnoses and illustrations are provided.
