TTT

There are sex differences in stages of addiction (see Table 1: (Becker et al., 2017, p. 137)). Women tend to show a greater sensitivity to stress and are less supported for being abstinent. A social problem is the greater stigmatization of addicted women, hindering their recovery [1]. Additionally, women in drug abuse treatment report more severe functional impairment as well as an overall lower quality in life. Women tend to seek treatment more quickly after the initiation of drug use and addiction onset than men. Differences in treatment outcome might emerge from gender differences, but overall behavioral therapy studies found similar outcome in men and women for treatments like cognitive behavior therapy or contingency management. There are controverse findings whether gender-specific treatments produce better outcome due to enhanced comfort, feelings of safety, etc. among women, but no evidence had been yet found [2].

In der nordwestlichen Ecke des Gebiets des Ortsteils Isenbruch befindet sich der westlichste Punkt[3] Deutschlands, der am 20. Juni 2015 feierlich als Erlebnisraum eingeweiht wurde. Auch schon vor[4] den Grenzverschiebungen nach dem Ersten Weltkrieg bei Eupen und Malmedy galt Isenbruch


Anonymization

Data discovery - [5]BC will make detail analysis of the system to find all the tables and fields that need to be updated during anonymization process. BC will deliver to HT list of tables and fields that will be included in process of anonymization in technical specification after analysis. Some tables will not be under anonymized/deletion by some short period of time (LOGS) or they don’t have the specific data even though they are extension of original table (HIST). Table that contains list of customers that HT has put on blacklist (BLACKLIST tables) will not be anonymized.

Anonymization – A new recurring process for anonymization. Update on the data (anonymization) will be done without sending update of master data to other systems (CRM and SAP) and with making Note in Notes but with special message defined only for anonymization.

The contract OIB identifies customers to be anonymized.

Processing

Processing is separated in two processing steps. First validation of data and secondly the anonymization process, supported by queue tables:

  • Validation: HTC_CUST_ANONYM_VAL_QUEUE
  • Anonymization: HTC_CUST_ANONYM_REQ_QUEUE


Preconditions

Postal Code 99999 for all countries has to be available in POSTAL_CODES_REF.

Validation
Candidate Check

Verify for data of queue table HTC_CUST_ANONYM_VAL_QUEUE that it adheres to the following rules:

  • Number of cancellation days defined in setting HTC_ANONYM_MIN_CANC_AGE (minimum number of months a customer has to be in cancellation before it can be anonymized).
  • Contract / Subscriber cancelled
  • Products cancelled
  • Service cancelled
  • Contract: all subscribers in a contract are in status cancelled or contract is empty
  • In case of duplicate OIB / JMBG: the first OIB / JMBG is processed if preconditions are fulfilled. The second one and perhaps further will be ignored.
Check Target Anonymized OIB

The purpose of this process is to check whether an OIB, JMGB that has been detected by DWH and Trust Center as candidate for anonymization can be anonymized in Billing Components. It is verified that the new planned anonymized OIB - OIB/JMBG is not already in use.
