The family Geometridae, which is one of the most species-rich taxa of Lepidoptera, includes more than 23,000 species worldwide and over 800 species in South Korea. Herein, we record six species of Geometridae for the first time in Korea. Jodis urosticta and Jodis amamiensis can be characterized by their greenish wings and strongly dentate ante- and postmedial lines on the fore and hindwings. These species can also be separated by the shape of the valva of the male genitalia. Pelagodes antiguadraria can be characterized by their greenish wings, whitish medial bands on the forewing and whitish postmedial line on the hindwing. Brabira kasaii can be characterized by the thick grayish band-shaped central fascia of their fore- and hindwings. Sauris marginepunctata can be characterized by the greenish ground color of the forewing, the dark ochreous medial bands and subterminal line and the grayish hindwing. Philereme vetulata can be characterized by their dark brownish wing color and the band-shaped central fascia of the forewing, as well as the medially projected postmedial line of the hindwing. Echthrocollix minuta can be characterized by their pale grayish wing color, brownish postmedial and subterminal lines and large discal dot.

Purpose: The aim of this qualitative study was to identify the experiences of smoking and smoking cessation in out-of-school youth. Methods: The participants were 12 out-of-school youths belonging the Youth support Center located in A and B area. The data were collected from January 8 to 15, 2018, using a FGI(Focus Group Interview). The main sub-domains of the experiences of smoking and smoking cessation in out-of-school youth by 7 questions were categorized from the intrapersonal, interpersonal, organizational, and community factors in ecological model. Results: The motivation, continuity, disadvantage of smoking experiences of out-of-school youth were analyzed in 10 sub-domains (curiosity, friend's invitation, mood of adapted group, habit, relieving stress, providing breaks, friendship, physical damage, loss of money, a bad sight of smoker). The reason, difficulty, advantage, reason for restarting smoking cessation experiences of out-of-school youth were analyzed in 15 sub-domains (physical damage, for future hope, invitation of others, influence of family, weight gain, emotional stress, worsening friendship, improvement physical condition, saving money, better relationships, not with bad friends, withdrawal, smoking of friends, drinking, separated a lover). Conclusion: Based on the results, it is expected that a Specialized Smoking Cessation Education Program will be developed for out-of-school youth's health activities in ecological factors.

For the first time, a single specimen (68.47 mm in total length) of Lumpenopsis pavlenkoi Soldatov, 1916 belonging to the family Stichaeidae was collected from the northernmost area of the eastern coast of Korea (Gosung, Gangwon Province) in April, 2020, using square net (1.0 m width, 0.3 m height, 2.0 mm mesh size). This species is characterized by elongated and compressed body, absence of lateral line and cirri on head, presence of scales on cheek, dorsal fin with only 50 spines, anal fin with 2 spines and 30 soft rays, and separated operculum and isthmus. The body is yellowish with 7 saddles. The new Korean name "Kko-ma-be-do-ra-chi-sog" is proposed for the genus Lumpenopsis, and "Deung-jeom-kko-ma-be-do-ra-chi" is proposed for the species L. pavlenkoi.

In this paper, we mainly study the random sampling and reconstruction of signals living in the subspace V^p(𝚽, 𝚲) of L^p(ℝ^d), which is generated by a family of molecules 𝚽 located on a relatively separated subset 𝚲 ⊂ ℝ^d. The space V^p(𝚽, 𝚲) is used to model signals with finite rate of innovation, such as stream of pulses in GPS applications, cellular radio and ultra wide-band communication. The sampling set is independently and randomly drawn from a general probability distribution over ℝ^d. Under some proper conditions for the generators 𝚽 = {𝜙_λ : λ ∈ 𝚲} and the probability density function 𝜌, we first approximate V^p(𝚽, 𝚲) by a finite dimensional subspace V^p_N (𝚽, 𝚲) on any bounded domains. Then, we prove that the random sampling stability holds with high probability for all signals in V^p(𝚽, 𝚲) whose energy concentrate on a cube when the sampling size is large enough. Finally, a reconstruction algorithm based on random samples is given for signals in V^p_N (𝚽, 𝚲).

The mechanism by which $V_H$ region gene segments is selected in B lymphocyte is not known. Moreover, evidence for both random and nonrandom expression of $V_H$ genes in matured B cells has been presented previously. In this report, the technique of in situ hybridization allowed us to analyze expressed $V_H$ gene families in normal B lymphocyte at the single cell level. The analysis of normal B cells in this study eliminated any posssible bias resulting from transformation protocols used previously and minimized limitation associated with sampling size. Therefore, an accurate measure of the functional and expressed $V_H$ gene repertoire in B lymphocyte could be made. One of the most important controls for the optimization of in situ hybridization is to establish probe concentration and washing stringency due to the degree of nucleotide sequence similarlity between different families which in some cases can be as high as 70%. When the radioactive $C{\mu}$ and $V_{H}J558$ RNA probes are tested on LPS-stimulated adult spleen cells, $2{\sim}4{\times}106cpm$/slide shows low background and reasonable frequency of specific positive cells. For the washing condition. 40~50% formamide at $54^{\circ}C$ is found to be optimum for the $C{\mu}$. $V_{H}S107$ and $V_{H}J558$ probes. The analyzed results clearly demonstrate that the level of each different $V_H$ gene family expression is dependent upon the complexity or size of that family. These findings are also extended to the level of $V_H$ gene family expression in separated bone marrow B cells depend upon the various stage of differentiation and conclude no preferential utilization of specific $V_H$ gene family. Thus, the utilization of VH gene segments in B lymphocyte of adult BALB/c mice is random and is not regulated or changed during the differentiation of B cells.

In Korea surrogate medical decision makings happen without legal grounds. The purpose of this article is to research the issues in preparing policies for decision-making on behalf of unrepresented patients. As aspects of comparative law, there are two approaches. One of them is to regulate default surrogate list. If no agent or guardian has been appointed, some legislatures provide that members of patient's family who is reasonably available, in descending order of priority of not, may act as surrogate: (1) the spouse, unless legally separated; (2) an adult child; (3) a parent; or (4) an adult brother or sister. If none of them is eligible to act as surrogate, some legislatures allow close friends to make health-care decisions for adult individuals who lack capacity. On the other hand there are other legislatures which provide no surrogate decision maker list but oblige the responsible authority to determine with advice of family members or friends of the patient. In the end the first approach can not guarantee that the surrogate decision maker like family members or friends will determine in the best interest of the patient.

Sea urchin S. intermedius occurring in the Korean east coast is a cold water species that belongs to the family Strongylocentrotidae of Echinoidea. Although it is known that there are nine species in the family, species identification criteria, phylogenetic relationships, time and process of evolution of the family members have not been uncovered clearly. In the present study, I tried to find some clues to such problems for S. intermedius by means of DNA sequences. For this, cytochrome c oxidase subunit I (COI), one of the mitochondrial genes that evolve fast and follow maternal inheritance was analyzed. DNA was extracted from the female gonad of S. intermedius, a segment of COI gene amplified by polymerase chain reaction (PCR), and finally a total of 1077 base pair sequence of COI obtained by cloning and sequencing the PCR product. The sequence was compared with homologous genes of other sea urchins and echinoderm species. Phylogenetic trees of the COI gene segment revealed that S. intenedius is a sister species of S. purpuratus which lives along the east coast of the Paciflc. With reference to the fossil records of sea urchins and genetic distances in the molecular phylogenies, it is estimated that the two species were separated about 0.89 million years ago when the earth temperature fluctuated significantly. The current disjunct distribution patterns of the two species and the climate change of the earth at the time of separation suggest that speciation might have occurred by vicariance. The COI gene sequence obtained here now can be used as a molecular character which discerns S. intermedius from the other sea urchin species of Strongylocentrotidae.

The Korean Mental Health Act was amended 2016 overall. This paper examines and evaluates the old Korean Mental Health Act since 1995 and the new Korean Mental Health Promotion Act 2016 from the Perspective of Human Rights and Inclusion of Persons with Psychosocial Disabilities. The persons with mental disabilities was separated and ruled out from society by the enactment of the Mental Health Act in 1995 and five times amendment. That has been justified and institutionally supported by medical viewpoint. The medical approach which reconsider the persons with mental disabilities as patients conceal that the aims of the involuntary admission in Mental Hospital are protection of society and the relief of the family member's duty of support for person with mental disabilities. This is institutionally supported in the 1995 Korean Mental Health Act by involuntary admission through the consent of family members as protectors. According to the old Act, the family members as protectors are authorized to consent to involuntary admission of persons with mental disabilities. Also, the psychiatrist that diagnoses the person with mental disabilities and evaluates the need for treatment by admission is not impartial in this decision. Family members as protectors may want to lighten their burden of support for the person with mental disabilities in their home by admitting them into a mental hospital, and the psychiatrist in the mental hospital can be improperly influenced by demand of hospital management. Additionally, Article 24 of the Korean Mental Health Act for the Involuntary Admission by the Consent of Family Members as Protector might violate personal liberty, as guaranteed in the Korean Constitution. The Mental Health Promotion Law was amended to reduce the scope of the persons with mental illness which are subject to forced hospitalization and to demand that a second diagnosis is made by another psychiatrist and screening by the committee concerning the legitimacy of admission in the process of the involuntary admission by the consent of family members as a method of protection. The amended Mental Health Promotion Law will contribute to reducing the number of the involuntary admissions and the inclusion of persons with mental disabilities. But if persons with mental disabilities are not providing some kind of service to the community, the amended Mental Health Promotion Law does not work for Inclusion of them.

Background: This paper aimed to verify the effects of renal replacement therapy on changing the levels of serum creatinine for different veno-arterial and veno-venous configurations in prolonged extracorporeal membrane oxygenation (ECMO) patients. Methods: The subjects were chosen 71 patients who had undergone more than 1,440 minutes (24 hours) of the therapy from among 117 patients who had undergone ECMO insertion between January 2008 and December 2012. The patients were separated into the veno-arterial configuration group I (51 patients) and the veno-venous configuration group II (20 patients). The difference in the level of serum creatinine (${\Delta}Cr$) between before or just after ECMO insertion ($Cr_I$) and the level when the pump time was between 2,880 and 4,320 minutes ($Cr_F$) was checked (${\Delta}Cr=Cr_F-Cr_I$), and the average ${\Delta}Cr$ for each group was compared using a Student t-test at the confidence interval (CI) of 95%. Results: The change in the level of serum creatinine was an increase of 0.341 mg/dL (${\sigma}$=0.9202) for group I and a decrease of 0.120 mg/dL (${\sigma}$=1.5292) for group II. The change was significantly high for group I (p=0.011, CI=95%). Meanwhile, within group I, when renal replacement therapy was not done, there was a significant increase in the level of serum creatinine (p=0.009, CI=95%). Conclusion: For ECMO insertion patients whose pump time was more than 1,440 minutes, there was a significant change in the level of serum creatinine when renal replacement therapy was not done, for the veno-arterial configuration of group I.
