2003년 고병원성조류인플루엔자(HPAI)가 발생된 이후 우리 양계산업은 겨울철만 되면 긴장을 늦출 수 없게 되었다. 해외에서의 인체 감염과 이에 따른 사망소식 등 위험성에 대해 미디어들은 축산농가들이 겪게 될 고통은 뒤로한 채 앞 다투어'조류독감'이라는 자극적인 표현을 내세우며 양계산업을 최악의 상태까지 몰아넣었다. 이러한 과잉보도는 국민들에게 불안감을 더욱 고조시켰으며 이는 바로 양계산물의 소비급감으로 이어져 양계산업을 큰 위기로 몰고 갔던 것이다. 정부를 비롯한 양계협회 및 관련단체들은 주요 보도 매체를 방문해 가며 기존에 사용했던'조류독감'을'AI'또는 '고병원성조류인플루엔자'라는 명칭으로 정정해 줄 것을 요청하였다. 또한 양계산물의 안전성을 보장하는 보험을 들면서까지 소비회복을 위한 노력에 동분서주하였다. 이렇듯 고병원성조류인플루엔자가 발생시마다 양계산업은 원자폭탄을 맞은 듯 큰 희생을 감내해야만 했다. 따라서 사전에 예방하고 피해를 최소화 하기위한 일환으로 고병원성조류인플루엔자의 발자취를 되돌아보고 농가들이 차단방역을 위해 준비할 내용을 정리해 보았다.

고병원성조류인플루엔자가 지난 4월 6일 전남 장흥에서 마지막으로 발생한 이후 한달 이상 추가 발생이 없어 종식단계에 접어들었다. 지난해 11월 26일 최초 발생한 고병원성조류인플루엔자는 235일간 가금농장에서 106건, 관상용 2건을 비롯해 야생조류에서 234건이 검출됐고, 이로 인해 487농가에서 3천만수에 육박하는 가금류가 살처분됐다. 이중 오리는 육용오리 96농가 184만9천수, 종오리 23농가 184천수가 살처분됐다. 특히 종오리의 경우 농가수로는 35%가 피해를 입었으며 사육수수로는 4월말 현재 산란종 오리수가 전년대비 17.1%가 줄어들었으며 평년에 비해서는 30% 가까이 줄어들었다. 때문에 당분간 육용오리 생산에 차질이 불가피하며 살처분 농가들의 입식도 늦어질 것으로 예상되고 있다. 이처럼 고병원성조류인플루엔자 발생으로 인해 국내 오리산업은 큰 피해를 입었으며 정상으로 회복하기까지는 상당한 시일이 소요될 것으로 예상된다. 우리나라 뿐만 아니라 전 세계적으로도 고병원성조류인플루엔자로 인해 몸살을 앓고 있다. 아시아는 물론 유럽, 아프리카, 북아메리카까지 고병원성 조류인플루엔자가 지속적으로 발생하고 있기 때문이다. 전 세계적인 고병원성조류인플루엔자 발생은 장기적으로 국내 오리산업에도 악영향을 미칠것으로 예상되고 있다. 원종오리를 수입하고 있는 영국 등에서도 고병원성조류인플루엔자가 발생함에 따라 가금류의 수입이 중단되면서 장기적으로 종오리 수급에도 차질이 예상되기 때문이다. 이에 이번호에서는 앞으로의 종오리 수급 현황 및 전망에 대해 살펴봤다.

This study was conducted to provide data pertaining to precocious puberty by comparing the psycho-social behavior of girls with precocious puberty to those with normal development. This study was conducted from 1 June 2016 to 25 February 2017. The subjects were 104 female patients of A group with precocious puberty visiting H Oriental medicine clinic and S clinic in Seoul, and 104 girls in control group A and 104 girls in control group B attending elementary school in gun. The psycho-social behavioral characteristics of girls with precocious puberty and those with normal development were compared among 312 girls matched for gender and age using a t-test, ${\chi}^2test$, and ANOVA. In addition, the factors influencing precocious puberty were analyzed through multinomial logistic regression. The results revealed that the primary influence factors were frequency of meat intake (p<0.01) and eating-out (p<0.05). These were followed by watching TV (p<0.001), hours of using smart phone (p<0.01) and number of private institutes attended (p<0.05). Additionally, emotional and physical indexes were lower in the precocious puberty group than the control group, indicating that they have more pathology.Finally, girls in the precocious puberty group have lower family and friendship indexes than those in the control group, which means they have more pathology. Overall, the results indicate that extensive research on the causes and frequency of precocious puberty is necessary.

This study was conducted to provide basic data for the prevention and management of precocious puberty by investigating the relevance of physical parents characteristics and behavioral characteristics of girls with precocious puberty. The research period was June 1, 2016 to February 25, 2017. The subjects were 312 girls matched depending on gender and age which were composed of 104 female patients of precocious puberty visiting H oriental medicine clinic and S one in Seoul, 104 girls of A control group and 104 girls of B control group attending elementary school in gun. A total of 312 of each group were compared though t-test, $X^2$-test, and ANOVA to examine the physical parent characteristics and behavioral characteristics between girls with precocious puberty and normal girls, after which influence factors for precocious puberty were analyzed through multinomial logistic regression. The main influencing factor was found to be the height of their own and mothers' menarcheal age in terms of body and parent characteristics. Other factors influencing behavioral characteristics included the frequency of meat intake and eating-out in terms of eating habits. Additionally, watching TV, hours of using smart phone and number of private institute girls attending were also found to be influencing factors. Thus, interest in school and society in increasing precocious puberty in girls is important and extensive investigation of the causes and frequency of precocious puberty is necessary.

This study is a qualitative study applying phenomenological methodology to understand the experiences of childrens with precocious puberty and to describe the whole meaning. Participants were randomly selected from six childrens who had been diagnosed with precocious puberty. From October 12, 2016 to November 18, 2016, data were collected through in-depth interviews with individuals and group interviews. The method proposed by Colaizzi (1978) was used to guide the process of data analysis. Four theme clusters were derived from interview data : the treatment chosen by the mother, uncomfortable treatment, illness not understood well, and don't want to get treatment again. we identified the various emotional and psychological difficulties experienced by childrens with precocious puberty. Future research should develop a nursing intervention program to reduce the burden of the children and accept the treatment as a positive emotion.

Precocious puberty (PP) is defined as the early development of secondary sexual characteristics (before the ages of 8 years in girls and 9 years in boys). The aim of this study is to identify characteristics of the dental maturity in girls with PP that discriminate them from normal healthy girls. This study included 99 girls aged 6 - 8 years with PP and 99 girls without past medical history of same chronological age (control group). The study was performed on 198 panoramic radiographs (99 PP girls, 99 control group girls). Demirjian method was used to evaluate the panoramic radiographs and determine dental maturity. Difference in dental maturity score and tooth formation stages between the two groups were analyzed. The PP group showed significant higher maturity score than control group. Among mandibular teeth, mandibular 2nd premolar and 2nd molar were significantly more mature in the PP group than control group. Logistic regression analysis showed that mandibular 2nd molar was only significant predictor for PP girls.

Congenital adrenal hyperplasia(CAH) is a recognized cause of precocious pseudopuberty. Some children with CAH also develop true precocious puberty with early maturation of the hypothalamic-pituitary-gonadal axis. We review a case of CAH who eventually developed central precocious puberty nine months after initial treatment with corticosteroid. A 3-year-old boy visited complaining of rapid growth, a large penis and frequent penile erections. This patient was diagnosed with CAH with elevated 17-OH progesterone and cortical hypertrophy of adrenal gland on CT scan. His gonadotropin levels were within the normal prepubertal range. Even on treatment with corticosteroid he grew rapidly and had testicular enlargement, pubic hair development and rapid bone maturation. At second admission, his gonadotropin levels were elevated both basally and in response to LHRH stimulation, suggesting that the CAH led to early activation of pubertal gonadotropin secretion(true precocious puberty). He was treated with monthly depot injections of a LHRH analog in addition to the hydrocortisone. His second sexual characteristics regressed gradually and rate of linear growth and bone maturation decreased.

The aim of the study was to determine Pb and Cd accumulation and to assess its trends in relation to age categories in feral pigeons from urban (Seoul) and industrial complex (Ansan) areas. This study shows that Pb and Cd concentrations in bone, kidney, liver, and lung increase with different developmental stages in feral pigeons. Particularly, Pb in the bones and Cd in the kidneys of birds were highly increased from chicks to adults. Mean Pb concentrations in pigeons from Seoul were three times higher in chicks than in eggs and six times greater in adults than in chicks. For Cd concentrations, pigeons in Seoul contained two times higher in chicks than in eggs and seventeen times higher in adults than in chicks. It indicates that Pb and Cd concentrations increase with age, and these are apparent to the results in Seoul than in the Ansan colony.

Behavior and decomposition velocity of pollutants on various forms from domestic sewage in sewage treatment plant were investigated in order to obtain the basic data for improving the removal efficiency of pollutants and to reduce the area in constructed wetland by natural purification method. The removal amounts of BODs and CODs in aerobic bed were significantly higher than those of the other beds. In aerobic bed, the removal amounts of IBOD and ICOD were more than those for SBOD and SCOD, respectively, whereas the removal amounts of BODs and CODs in anoxic and anaerobic beds were little different. The removal amounts of SSs in aerobic bed were also higher than those for the other beds, and the removal amounts of VSS in all beds were more than those for FSS. The removal amounts of DTN and DTP in all beds were more than those for STN and STP, respectively. In addition, the decomposition velocities of TBOD, TCOD and TSS in aerobic bed were 30.79, 17.15 and 29.96 $day^{-1}$. Moreover, the decomposition velocities of BODs, CODs and SSs in aerobic bed were very rapid than those in the other beds. On the other hand, the decomposition velocities of BODs, CODs and SSs in anoxic and anaerobic beds were a little different regardless of the forms of pollutant. The decomposition velocities constants of T-N in aerobic, anoxic and anaerobic beds were 4.78, 0.12 and 0.10 $day^{-1}$, respectively. Moreover, the decomposition velocities constants of T-P in aerobic, anoxic and anaerobic beds were 13.09, 0.12 and 0.13 $day^{-1}$ respectively. The decomposition velocity of T-Ns and T-Ps in aerobic bed were slightly rapid than those in the other beds, whereas the decomposition velocities of T-Ns and T-Ps in anoxic and anaerobic beds were slightly different regardless of the forms of pollutant.
